Note 1: The rated torque is the output torque of the output speed of 15rpm. The input power considers the efficiency of the reducer.
Note 2: Torque calculation formula:
T=9549XPXη/N （T: Nm, P: Kw, N: RPM, η: % )。T=9549XPXη/N (T: Torque Nm, P: Power Kw, N: Speed RPM, η: Efficiency %).
Transmission Precision, Torsional Stiffness, Backlash And Backlash
* The torsional stiffness, backlash and backlash of the gear reducer shall meet the requirements of table 5 and table 6.
* The transmission accuracy of gear reducer shall conform to the requirements of table 5 and table 6.
Life
* When the reducer is working on rated speed and on-loading, reducer ‘s lift time is more than 6000 hours.
Allowable Torque (Bending Torque)
* The instant allowable torque is generally twice the allowable torque of the reducer.
* The allowable torque of the gear reducer shall meet to the requirements of table 5 and table 6.
Overload
* After reducer working under over-load for 5min with 125% rated torque, dudring the running, it have no noise and other damage.

Note: Inertial moment value is the value of the reducer unit, without considering the inertial moment of the central gear and the input gear. For the inertia moment value converted by the motor shaft, refer to the following formula.
Lubrication
* The lubrication grease is not filled before gearbox leave factory. Please fill in the suggested lubrication grease during assembly, the amount is roughly 70~90% of the gearbox inside cavity volume
* Lubricating grease is generally replaced in 2000 hours. When the grease is contaminated or is used in harsh environments, it is necessary to check the condition of aging and pollution and to change the time
* Reducer using lubricating oil: Molywhite RE-00 or VIGO-grease REO other similar grade precision reducer special grease
