SPN series planetary Reducer
MOQ: 10 PCS
Note: If you have any questions,please contact us
- 1.SPN series planetary reducer adopts two structural forms of coaxial type and angle type, with 1-4-stage transmission.
- 2.The box body is made of nodular cast iron with high bearing capacity. The sun gear and planetary gear are meshed with straight teeth. The gears and bevel gears are hardened, shaped and ground.
- 3.The internal gear ring is mainly quenched and tempered at high temperature. The gear teeth are designed for infinite fatigue life according to the given torque.
- 4.This series of products are widely used in metallurgy, mining, cement, chemical industry, building materials, engineering machinery, hoisting, port ships, belt transportation and other subdivided fields.
- 5.It can be flexibly combined into multiple types. It can be combined with four series of products to make the transmission ratio larger and the application range wider

OUTPUT TORQUE
Reference torque M2[Nm]
Indicative output torque to easily establish the performance class for each gearbox basic size
Nominal torque Mn2[Nm]
The condition is that the torque of the gearbox can be transmitted safely:
Uniform load,the safety factor is 1
Theoretical life is 10000 hours
Maximum torque M2max[Nm]
It is the output torque that the reduction unit can withstand in static or highly intermittent conditions.
It is considered as instantaneous load peak torque or stanting torque under load.
Required torqueMr2 [Nm]
This is the torque corresponding to application requirement.
It must always be equal to or less than rated output torque Mn2 of the selected geart
Calculate torque Mr2[Nm]
Torque value to be used for selecting the gearbox,considering required torque Mr2 and service factor fs,and is obtained by formula
