4.1. Power P

P1 = [KW]

P1n ≥ P1 [kW]

P1 Input powerP2 Output powerP1n Rated power of motorn Transmission efficiency

The efficiency of WAH gear units varies with the number of gear stages, between 92 % (2-stage), 90%(3- stage).

4.2. Rotation speed n

n1 Input speed of reducern2 Output speed of reducer

If driven by the external equipment,1400r/min or lower rotation speed is suggested to be used in order to optimize the working conditions and prolong the service life. Higher input rotation speed is permitted, but in this case,the rated torque M2 will be reduced.

4.3. Transmission ratio i

i =

Usually transmission ratio is decimal fraction with 2 radix point tagged in selection tables.

Three load classifications are considered depending on the inertia coefficient. You can read off theservice factor applicable to your application in following Figure.The service factor selected using this diagram must be less than or equal to the service factor as given in the performance parameter table.

4.5.1 Load Classifications

A Uniform shock load, permitted mass acceleration factor fa ≥ 0.2B Moderate shock load.permitted mass acceleration factor fa ≥ 3C Heavy shock load.permitted mass acceleration factor fa ≥ 10

Load classifications:

A Screw feeders, fans, assembly lines, conveyor belts, small mixers, lifts, cleaning machines, fillers, control machines.B Winding devices, woodworking machine feeders, goods lifts, balancers, threading machines, medium mixers, conveyor belts for heavy materials, winches, sliding doors, fertilizer scrapers, packing machines, concrete mixers, crane mechanisms, milling cutters, folding machines, gear pumps.C Mixers for heavy materials, shears, presses, centrifuges, rotating supports, winches and lifts for heavy materials, grinding lathes, stone mills, bucket elevators, drilling machines, hammer mills, cam presses, folding machines, turntables, tumbling barrels, vibrators, shredders.

4.5.2 Interial co-efficient

The interial coefficient is calculated as follows:

fa =

fa Coefficient of inertiaJc All external moments of inertia(kgm2)Jm Moment of inertia of the motor (kgm2) If coefficient of inertia fa> 1O

To keep the lifetime of reducer, the use factor feselected from the catalogue must be equal or slightly higher than actual application service factor fs.

Example: Inertial coefficient of 2.5(1oad classification B), 14 hours/day operating time (read off at 16 h/d) and 200 stop/hour result in a service factor fs = 1.48. According to the parameter sheet, we choose the service factor fB ≥ 1.48

4.6. Radial loads and axial forces

When determining the resulting radial loads, the type of transmission elements, mount-ed on the shaft end must be considered. Various transmission elements are corresponding with following transmission element factors fz:

The radial loads exerted on the motor or gear shaft is then calculated as follows: Fr = [N] Fr Resulting radial load [N]M Torque on the shaft [Nm]do Mean diameter of transmission element mounted on shaft [mm]fz Additional transmission factor

The basis for determining the permitted radial loads is based on the rated service life L10th of the bearings (according to 150281). Function point is placed in the middle of exposed part of output shaft.

The permitted radial loads given in the selection tables must be calculated using the followingformula in the event of force application not in the center of the shaft end. The smaller of the twocalues FxL(according to bearing service life)

FxL according to bearing service life:

FxL = Fr2 • [N] Fr2 = Permitted radial load (x=L/2) according to he selection tables in [N]x = Distance from the shaft shoulder to the force application point in [mm]a,b = Constant conversion of radial load [mm]

1. Check whether the rotation direction of output shaft of reducer is correct before fitting to the machine.2. Before connect with the prime mover and device, please check every axial diameter, aper ture, key and key slot, to be sure their dimensions are not deviation, and avoid assembling too tight or too loose, or it could influence the performance.3. The mounting on the machine must be stable to avoid any vibration.4. Whenever possible, protect the reduction unit against solar radiation and bad weather.5. In the case of particularly lengthy periods of storage (4-6 months), if the oil seal is not im-mersed in the lubricant inside the unit, it is recommended to change it. It is because the rubber could stick to the shaft or may even have lost the elasticity.6. When connect with hollow or solid shaft, please grease the joint to avoid lock or oxidation.7. Check the correct level of the lubricant through the oil mirror, if there is one.8. Starting must take place gradually, without immediately applying the maximum load.9. Supporting unit is required when using reducer that connects with motor directly, if the weight of motor is comparatively heavy.10. Ensure the motor cools correctly by assuring good passage of air from the fan side.11. Standard working temperatures should be between -5˚C to +40˚C, if not, please call the Technical Service.

10. INSTALLATION 10.1. Note Recommendations

10.2. Service Restrictions

1. As speed increase based on datasheet.2. Applications with especially high inertia.3. Use in services that could be hazardous for people if the reduction unit fails.4. Applications with high dynamic strain on the case of the reduction unit.5. When working temperature is under - 5˚C or over +40˚C.6. Use in chemically aggressive environments.7. Use in a salty environment.8. Use in radioactive environments.9. Use in environments pressures other than atmospheric pressure.10. Mounting positions not mentioned in the catalogue. Avoid applications where even partial immersion of the reduction unit is required. The maximum torque that the gear reducer can support must not exceed two times the nominal torque (fs=1) stated in the performance tables. Intended for momentary overloads due to starting at full load, braking, shocks or other causes, particularly those that are dynamic.

Specification on this catalogue is organized according to standard of general reducer. It is also neces-sary to take due consideration of and carefully assess the following applications by calling our Tech-nical Service:

WAH... Lubricant fill quantity

11.2. Lubricant VolumeThe specified fill quantities are recommended values.The precise values vary depending on the number of stages and gear ratio. When filling, it is essential to check the oil level plug since it indicates the precise oil capacity. The following tables show guide values for lubricant fill quantities in relation to the mounting position (B3, B6, B7····)

11. LUBRICATION 11.1. Types of Lubrication

*It means the lubricant can’t be added according to the oil mirror level, but also higher than the plug. The filled volume is shown in the table.

1. First oil change should be done after 300 working hours (run-in period) or three months. Never mix the syntheic oil and mineral oil together.2. Every 3000 working hours, at least every 6 months, check the oil and oil level, the seals visu-ally for leakage.3. Depending on the operating condition (see chart below), every 3 years.

1. Protected against rainand snow, no shock loads.2. Lay block or other material between the ground and equipment.3. The opened but not used gear units should have anti-corrosive oil on its surface, and then return to the packing containers.4. If reducer is storage for 2 years or more, please check cleanliness and mechanical damage, and whether corrosion protection is still there.

Please offer the following information when place the orders:1. Type of the reducer(type,ratio,power and mounting position2. Generally the gear units paint in silver3. Order quantity4. Other special requirements5. Company, contact person and telephone number
