Note 1: The rated torque is the output torque of the output speed of 15 r/min. The input power considers the efficiency of the reducer

Note 2: Torque calculation formula: T=9549XPXη/N （T: Nm, P: Kw, N: r/min, η: % )。T=9549XPXη/N (T: Torque Nm, P: Power Kw, N: Speed r/min, 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.

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
