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.

What is a Gearbox and How Does It Work?
A gearbox is a mechanical device that transmits power and changes the speed or torque of a rotating input shaft to a different output shaft. It is commonly used in various machines and equipment to control the speed and direction of motion.
Here’s how a gearbox works:
- Input Shaft: The gearbox receives rotational energy from an input shaft connected to a power source, such as an electric motor or an engine.
- Gears: Inside the gearbox are a set of gears with different sizes. These gears mesh with each other, and their arrangement determines the gear ratio, which defines how many revolutions the output shaft will make for a given rotation of the input shaft.
- Output Shaft: The output shaft is connected to the machinery or equipment that needs to be powered. As the gears rotate, the motion and power are transmitted from the input shaft to the output shaft.
- Gear Ratio: By selecting different gear combinations, the gearbox can change the speed and torque of the output shaft. A higher gear ratio results in higher torque and lower speed, while a lower gear ratio provides higher speed and lower torque.
Gearboxes play a crucial role in various applications, including automobiles, industrial machinery, robotics, and more, enabling efficient power transmission and speed control.
