Strain Wave Drive


Strain Wave Drive ® strain wave gearing utilizes a unique operating principle which is based upon the elastic mechanics of metals. The greatest benefits are the zero-backlash characteristics and the weight and space savings compared to other gears because our gear mechanism consists of only three basic parts. They are the: Wave Generator, Flexspline and Circular Spline.

This simple three element construction combined with the unique operating principle allows extremely high reduction ratio in a very compact and lightweight package. Neither the size nor weight of the gear vary with the reduction ratio. The high performance attributes of this gearing technology including zero backlash, high torque, compact size, excellent positional accuracy and repeatability are all a direct result of the unique operating principle.

Harmonic Drive

Strain Wave Drive LHSG

The LHSG high-torque hollow-shaft flexspline strain wave gear uses high-rigidity bearings and an overall strengthened design to increase the torque carrying capacity by more than 30% compared to the LHS harmonic speed reducer standard series. In addition to reducing the weight of machinery and equipment, the decrease in the weight of industrial robots can increase the robot's speed and payload weight


Strain Wave Drive LCSG

The LCSG high-torque cup-shaped flexspline strain wave gear is the high-torque version of the standard LCG model. It comprises high-rigidity roller bearings and an overall strengthened design. The torque carrying capacity is 30% higher than that of the LCS series. The LCSG high-torque cup-shaped flexspline strain wave gear has high torque capacity, a simple structure, high rigidity, low backlash, and long life. While bearing high torque, it can increase the operating speed to save installation space and reduce overall costs.
