*Specification with * mark: The D/F/K indicate the mounting positions in the shaft direction and allowance of the three parts--wave generator, flex spline, circular spline.
Strictly follow the requirement of these specifications as they affect the performance and intensity.

*Please note that in the circular spline there does not incorporate an O-ring groove (ymbol f). Please provide alternate sealing arrangements during the designing and installing.

*Due to the deformation of the Flexspline during operation, it is necessary to provide a minimum housing clearance, dimensions Φa, b, c.

*The wave generator is packed separately when the product is delivered.

*The following dimensions can be modified to accommodate customer-specific requirements.
Wave Generator: C
Flexspline: O and P

Circular Spline: X1 and X2

Note 1: It is recommended to have a housing undercut on the install concave.

Note 2: Refer to the confirmation drawing for detailed dimensions. Especially be certain to check the delivered specifications since the configuration of the wave generator varies depends on the size.

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

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

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.

Overload

* After reducer working under over-load for 5min with 125% rated torque, dudring the running, it have no noise and other damage.

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
