Product Description
Product Description
High-speed gearboxes designed and manufactured in MASPTT are designated primarily for power generation industry, compressor and pump applications. The manufacture is carried out on the modern machine tools and gearboxes are assembled using own components or components supplied by professional manufacturers. All products undergo thorough testing on a dynamic test bench.
The design and gear strength calculation are performed according to API 613 5th Edition and AGMA 6011(Other standard can be applied if requested.).
The gearbox is self supporting and does not need any reinforcement. It has a foot flange for mounting to a foundation and jack bolts (levelling bolts) for easy installation. The gearbox does not require any special maintenance. It is recommended to change the oil on regular basis or when changing the climate conditions – see the Operating Manual for details.
Standard gearbox is adjusted for high speed operation in the temperature range between -50 / +50°C provided the oil preheating at low temperatures and oil cooling at high temperatures. Should the gearbox be operated in hazardous area or under other special conditions, it has to be contractually agreed. The standard gearbox effi ciency is usually higher than 98,5%. Total efficiency depends on plenty of factors, such as mesh losses, bearing losses, windage losses etc. Wikov is capable to prepare customized solution to increase the gearbox effi ciency up to 99,5%.
Mesh losses
gearing is sized based on the transmitted power. Power is given by a customer. It is not possible to reduce mesh losses considerably, however MASPTT aims to optimize the losses to achieve the best compromise together with gear life, durability and NVH behaviour.
Bearing losses
these losses have the biggest influence on the gearbox efficiency. It is necessary to design and size the bearing properly.
Windage losses
Windage losses have big influence on the gearbox efficiency if the gear circumferential velocity is high. It is possible to reduce these losses (up to approx 50%) by using the windage cover.
Other losses
gearbox efficiency is also affected by the oil pump losses (if used), oil injection loss etc.
Product Parameters
Main Gearbox Components
Housing
The housing consists of 2 parts: the upper and the lower case. It is fabricated steel construction. The housing is optimized by CAE methods to ensure for good stiffness, low noise emissions, excellent cooling properties and minimum weight.
In the lower part there are feet for fixing the gearbox to the foundation equipped by jack bolts and with provision for mounting of earthing screw (if the gearbox is determined to the hazardous area). There is also located the oil input/output fl CHINAMFG and provision for temperature detectors conduction to the junction box. In the upper part there is an inspection cover, checking the proper lubrication of meshing gears, a breather and provision for vibration probes. Split face of the casing is horizontal, parallel to shaft axis. Both parts are connected by bolts and fixed by dowel pins.
Shafts and gears
Both shafts are forged pieces. HS shaft is forged from 1 piece along with gearing. LS shaft and the gear are forged separately and the gear is heat assembled on the shaft. The backsplash ring is usually forged from 1 piece with the shaft or heat assembled. Both gears are ground to high precision. Teeth fl anks of HS pinion have special modifi cations to reduce the noise level and compensate the deflection of shafts due to heavy load.
A hunting tooth combination exists for mating gears when a tooth on the pinion does not repeat contact with a tooth on the CHINAMFG until it has contacted all the other CHINAMFG teeth.
The shape of shafts ends depends on customer’s request (cylindrical, tapered, fl anged etc.).
Both shafts are dynamical balanced according to ISO 1940 or API 613.
Bearings
Solely hydrodynamic bearings with more sliding faces are used due to high speeds and bearing load. These bearings are divided into bearings with:
• fixed geometry – there is no movement of sliding faces • tilting pads – sliding faces are moving.
LS (low speed) shaft is usually placed in plain journal bearings with cylindrical clearance (fi xed geometry). One of the bearings is radial (on the non-driving end) and the other 1 (on the driving end of the shaft) is combined radialaxial bearing. The design and calculation of the bearings are performed according to the latest methods.
Bearings on HS (high speed) shaft are usually tilting pad type due to high speed and pitchline velocity and both of them are radial bearings.
Tilting pad bearings usually have 4 or 5 pads and static load direction goes either on 1 pad or between pads. Lubrication of these bearings can be reached by overflowing the space between pads or oil injection between pads by means of several nozzles which also protects pads against circumferential movement. When oil injection is used it is possible to reduce friction losses considerably. These bearings have the highest resistance against rotor instability because they do not generate any load causing instability.
Shaft sealing
Shafts sealing is provided by means of labyrinth seals and backsplash rings. Sealing design generally depends on the shaft revolution, operating conditions and environment. The advantage of labyrinth seal is that it is not exposed to friction scuff . That is very eff ective way of touch free sealing proper particularly for high speed and relatively dusty environment. It is possible to use it for low and high temperatures without any special provisions.
Labyrinth seal shall operate in horizontal position. It is necessary to size the oil drain from bearing space the way to prevent the oil leakage.
Case sealing
The gear case sealing in the split face and under all lids is ensured by LOCTITE or another similar sealant.
Lubrication
Lubrication of gears is performed by internal piping with spraying nozzle. Bearing lubrication is provided through internal oil passages in the gearbox casing. Oil drain from bearing space is ensured by means of adjustment of gearbox casing.
The nominal oil pressure is in the range of 0.1 – 0.15 MPa. Oil viscosity is ISO VG 46 or 32. Oil working temperature at bearings should be between 80° and 95°C at maximum.It is necessary to prevent mechanical impurities getting in the lubrication system. The permitted size of oil impurities behind the oil fi lter is 10 – 25 µm.
Cooling
Sufficient cooling of the gearbox is ensured primarily by natural radiation, i.e. the heat accumulated in the oil is released into the surrounding area by radiation and convection. The temperature of oil entering the gearbox shall not exceed 50°C. Unobservance of this temperature results in reduced service life of the product. Standard lubrication unit (incl. cooler, fi ltration etc.) shall be used for gearbox cooling and lubrication.
Sensors and monitoring
Gearboxes can befitted with various temperature, vibration, speed and shaft axial displacement probes. Remote gearbox diagnostics is optional equipment of the gearbox.
Gearbox Testing
Load tests of high-speed gearboxes Testing laboratory for high-speed gearboxes is a camera monitored modern workplace at Wikov manufacturing plant in Pilsen. The Dynamic Test Bench is a testing facility equipped with a computer controlled 1 CHINAMFG motor with speed up to 3.600 rpm, controlled load by a generator up to 710 kW of power, auxiliary gearboxes enabling testing of the main gearbox with speed up to 35.000 rpm. The test bench have a lubrication centre with adjustable oil fl ow from 10 to 1.600 liters/ minute, controllable oil temperature and water cooling up to 800 kW of power. The lubrication is backed up with pneumatic pumps supplying full volume of oil in case of power outage. The testing process is automatically recorded while oil and bearing temperature, pressure, noise, absolute and relative vibrations are measured and transferred to a control room for assessment by a specialized software.

Types of Gearboxes Used in Wind Turbines
Many manufacturers of wind turbines have chosen different solutions for the drive train of the turbines. Most prefer gearboxes because of their durability. These have several design features that make them well suited to shocks, stresses and wear. Regardless of the type of gearbox used, continuous maintenance and monitoring can extend the lifespan of these machines. Performing these tasks regularly can help detect and resolve any problems before they become serious. Here are some of the problems associated with gearboxes.
Coaxial helical gearbox
The R series helical inline gearbox is a high-quality speed reducer for heavy-duty industrial applications. These units are designed with increased power density in mind and are equipped with various cooling options. High-grade seals and lubricants help to increase efficiency and minimize thermal loading. They are ATEX-compliant. Their reversible modules are an excellent choice for high-speed applications, such as compressors, compressor blowers, and pumps.
The normal module set of helical gearbox is manufactured using the same tooth-cutting techniques as spur gears. This allows the production of higher-quality, more economical, and more compact helical gears. Although the performance of helical gears is lower than spur gears, they are durable and capable of transferring motion and power between two shafts. And because they are able to handle a much greater load, they are preferred for heavy-duty applications.
The main tooth form of a helical gearbox presents fixed velocity ratios, even if the center gap is not completely set. This requirement is sometimes referred to as the fundamental rule of gearing. A helical gearbox is similar to a set of paper spur gears, with the exception that the sections must stagger in opposite directions. There are two kinds of helical gears for parallel shafts: left-handed and right-handed.
The Industrial Gearbox market is segmented based on product type, application, and geography. The report analyzes the competitive scenario by segmenting the market by region, company, and type. Using this information, it estimates market size, revenue, and consumption. The report also features key information about COVID-19 and its impact on the overall industry. And it also provides a competitive landscape with industry-leading players.
Industrial gearboxes are integrated with devices and make automation processes more efficient and reliable. Increasing labor costs, shortage of skilled labor, and the ageing workforce are driving the demand for automation technologies. The industry requires newer and more advanced models and technologies to compete in the global market. You can use Coaxial helical gearbox in a variety of applications. Its benefits are endless. If you are looking for a reliable, high-performance industrial gearbox, CZPT can help you find it.
Worm reduction gearbox
As a general rule, larger center distance worm reduction gearboxes are more efficient than smaller ones. Worm gearboxes with 2.6-in. center distances start to lose efficiency as their ratios increase. Larger center distances tend to have higher efficiency than smaller ones. However, this difference may not always be enough to justify the higher investment. Worm gear reducers typically cost less than equivalent helical units.
The use of aluminum for worm reduction gearboxes is a popular choice for those involved in the manufacturing of Packaging Equipment. In addition to being lightweight, aluminum worm reduction gearboxes have high strength and rigidity. Manufacturers recommend this choice because of its high rigidity and durability. While purchasing aluminum worm reduction gearboxes, keep in mind that they are more expensive than steel versions. However, they have a longer lifespan and are highly resistant to wear.
The worm’s helix angle is larger than a helical gear, which allows a much higher gear ratio. In addition, the worm’s body is usually longer in the axial direction than helical gears. Worm reduction gears are often left-handed, and British or Indian standards are usually followed. The worm wheel is made of hardened alloy steel PB2-C, while the gearbox case is made of hardened alloy steel FG 220 or FG 250res.
The worms in a sacrificial system are relatively safe from wear. Instead, the softer wheel is the cause of most wear and tear. The oil analysis report for a sacrificial system shows low iron levels and high copper concentrations. However, if a worm reduction gearbox has a bad reputation, you should consider purchasing a new one. If the worm gears are in good condition, the gearbox is still a viable option for a new or replacement vehicle.
The advantages of a worm reduction gearbox are numerous. The worm gearbox is widely used in industrial settings, where it provides torque and speed reduction to move products. Worm gearboxes are also commonly used in automatic security gates, which will not run in reverse. Most security gates use two separate worm drives to keep the gate in the closed position. There are also many other uses for worm reducers. You can learn more about the benefits of worm gearboxes by reading below.
Stainless steel gearbox
Stainless steel gearboxes offer a number of advantages over standard gearboxes. They match the existing stainless motor design and cost 50 percent more on average. They have stainless output shafts and housings as well as corrosion resistant hardware and a food grade lubricant. Stainless steel gearboxes feature IP 65 sealing, Viton shaft seals at the input and output shafts, and a Buna o-ring between the housings. Stainless steel gearboxes also eliminate flat surfaces and allow for a cylindrical design.
Stainless steel gearboxes are more durable than traditional cast iron or epoxy-painted gearboxes. These gearboxes can withstand repeated washdown operations without damage. They also do not collect particles or bacteria. And because stainless steel does not corrode, stainless steel gearboxes can withstand harsh environments, such as oily or greasy environments. Because stainless steel gearboxes are corrosion-resistant, they require little maintenance. They are also easier to clean and maintain, resulting in fewer replacements and a longer life span for your gearbox.
Stainless steel gearboxes are a great choice for food and other industries that require high hygiene standards. In addition to its durability, stainless steel gearboxes are ideal for applications in environments that require high levels of humidity and water. They are also life-lubricated, and they can be supplied with food-grade oils or water. The CZPT Gears stainless gearbox is a versatile option for a variety of applications.
Stainless steel gearboxes offer superior corrosion protection and can withstand harsh environments. The stainless steel cover, housing, and external hardware ensure superior corrosion protection. If you have questions about the varying benefits of stainless steel gearboxes, contact a CZPT Gear sales representative to learn more about your options. And if you are not sure which type is right for your needs, contact a CZPT Gear sales representative to find the perfect solution for your business.
1 speed gearbox
Volkswagen Group Components manufactures the one speed gearbox. The gearbox has a high-performance electric drive motor that produces 310 Nm of torque over a wide speed range. Designed for maximum range, this gearbox uses a single gear for all driving situations. It is extremely quiet, too, and requires precision manufacturing. Volkswagen has also made it available in a reverse-gear configuration with power electronics. Volkswagen’s ID.3 EV’s e-drive motor is a perfect example of this.
The first part of the transmission corresponds to the even and odd gears, while the second part has the straighter gears. A single gear set can change between both modes. An intermediate gear set is also possible. A lastshelf gear can be formed by hydraulically betigte Lamellenkupplungen. Both types of gears can be exchanged between partial transmissions. The invention may furthermore include a transmission with the same gear ratios as the first part of the transmission.
Another variation of the one speed gearbox is the CVT. This type of gearbox has only one drive unit, which means it does not require a clutch or brake. Its power is derived from the torque generated by the Internal Combustion Engine at a particular speed. The engine cannot sustain such high torque levels above 5500 RPM, which will reduce the MPG. Also, raising the RPM will reduce the acceleration, and in severe cases may lead to an engine crash.
As the number of applications for a 1 speed gearbox increases, its design and functionality will continue to evolve. Bosch Rexroth has developed its eGFZ gearbox based on customer feedback. They are currently working on various pilot projects and hope to put it into production in the next few years. However, if you want to buy a 1 speed gearbox now, consider the benefits of a first-rate design.
