Specification

Advantages

The DHSG-IV series flexible wheel is a hollow flange standard cylinder structure, with an integrated input real shaft of the wave generator; built-in direct support bearing; fully sealed structure, easy installation, very suitable for applications where synchronous belt or bevel gear transmission is installed from the input end.

1.High torque The torque capacity of the high-torque type is 30% higher than that of the ordinary series, and the service life is increased by 40%
2.The lightweight shell design is lighter, faster in heat conduction, and less vibration than the full-steel type.
3.Ultra-low backlash, Large-diameter hollow hole flat shape
4.Compact and simple design Excellent positioning and rotation accuracy
5.High torque capacity. Input and output coaxial
