RVE Type Reducer Installation Essentials

In order to make fully use of RVC type reducer, it is need to make a best design of the assembly precision, installation method, lubrication and seal.

■Assembly Precision

Coaxiality tolerance (a) of motor shaft and reducer is lower than 0.03mm (For models above 280BX, lower than 0.05).

Because of the poor assembly accuracy, especially easy to cause vibration and noise.

•Figure C.1: Assembly precision

•Figure C.2: Assembly seal

■Assembly Method

•The assembly according to the specified dosage specified sealed grease.

•Reducer assembly in the supporting parts of the standard icon, shown in figure C.2, figure C.2 in the "O" ring position to be sealed.

•If the structure is not allowed to use the "O" - shaped ring, please use the table C.3 liquid sealant.

•Assembly diagram and "O"-shaped ring seal size, see figure C.2, figure C.3, figure C.4, and table C.1, table C.2.

■Input Gear

•Standard input gear is without any machine mouting hole of the motor.

•Install sample as shown in picutre C.5: (Three way)

•Input gear customized service

Our company can provide input gear customized service according to motor.

150BX, 190BX have 2 planetary gears. Please pay attention to put gear directly, correctly, and lightly when mounting gear. Do not use force, do not be incline when mounting. (Figure C.6)

•To be able to hole-through ratio of gearbox and cann't hole-through ratio.

To be unable to hole-through ratio as table C7, install sample as shown in picutre C.8.

Note: Table 2 is shown hole-through ratio. To be able to hole-through ratio of gearbox is C.7:

•Figure C.7: To be able to hole-through ratio of gearbox intall shown

•Figure C.8: To be unable to hole-through ratio of gearbox intall shown

■Lubrication

•Reducer using lubricating oil: Molywhite RE-00 or VIGO-Grease REO other similar grade precision reducer special grease.

•When the gear reducer is not filled with grease, it is recommended to fill the grease at the time of installation, and the filling amount is about 90%. of the internal cavity volume of the reducer.

•Lubricating grease standard replacement time is 20000 hours. When the grease is contaminated or is used in harsh environment, it is necessary to check the condition of aging and pollution, and changed within the allotted time.

•Reducer lubrication grease recommended dosage as shown in table C.8:

•Grease filling position as shown in figure C.9, figure C.10:
