90mm 750W 51: 1 Flange Output High Torsional Rigidity Speed Reducer

90mm 750W 51:1 flange output high torsional rigidity speed reducer for five axis machining center developed and manufactured by WEITENSTAN together with German and Taiwan technicians for many years.

High precision miniature cycloidal gearbox has the characteristics of smaller, ultra-thin, lightweight and high rigidity, anti-overload and high torque. With good deceleration performance, smooth operation and accurate positioning can be achieved. Integrated design, can be directly connected with the motor, to achieve high precision, high rigidity, high durability and other advantages. It is designed for high speed ratio, high geometric accuracy, low motion loss, large torque capacity and high stiffness applications. The compact design (minimum OD ≈40mm, currently the world's smallest precision cycloidal pin-wheel reducer) allows it to be installed in limited Spaces.

 

90mm 750W 51:1 flange output high torsional rigidity speed reducer advantages:

 

1, fine precision cycloidal structure

Ultra flat shape is achieved through differential reduction mechanism and thin cross roller bearing, contributing to the compact size of the equipment. The combination of small size and unmatched superior parameters achieves the best combination of performance, price and size (high cost performance).

 

2. Excellent accuracy (transmission loss ≤1 arcmin)

Through the complex meshing of precision cycloid gear and high precision roller pin, higher transmission accuracy is achieved while maintaining small size and high speed ratio.

 

3, high rigidity

Increase the mesh rate to disperse the load, so the rigidity is high.

 

4. High overload capacity

It maintains trouble-free operation under abnormally low noise and vibration conditions while ensuring excellent overturning and torsional stiffness parameters. Integrated axial radial cross roller bearings, high load capacity and overload capacity of the reducer, can ensure users to provide a variety of temperature range of applications.

 

5, the motor installation is simple

Electromechanical integration design, can be directly connected with the motor, any brand of motor can be installed directly, without adding any device.

 

6. Maintenance free

Seal grease to achieve maintenance free. No refueling, no mounting direction restrictions.

 

7, stable performance

The manufacturing process of high wear-resistant materials and high precision parts has been certified by ISO9000 quality system, which guarantees the reliable operation of the reducer.
