The harmonic drive transmission is using the flexible components elastic deformation of controllable to deliver the movement and power, its characteristic is, big transmission ratio and wide range, high precision, small returned empty, high loading , high efficiency, small volume, light weight, low noise, smooth transmission, to seal space.

The harmonic drive transmission includes three basic components: wave generator, soft wheel, just wheel and flexible bearing. The flexible bearing is the core component, the transmission through the bearing of the elastic deformation to achieve high performance requirements of the deceleration.

Flexible bearing at work, inner ring installation in the oval on the just round, work under cyclic stress load, outer ring installation in the gentle round up, work with soft round elastic deformation of the constant change, not only under cyclic stress load, but bear alternating stress load.

These characteristics of bearing inner ring and outer ring and maintains a design and manufacturing put forward high requirement , foreign, only Japan and the United States, and a few countries can production. Luoyang bearing group Co., LTD. The harmonic drive speed changing device is used for the design and manufacture of flexible bearing level, has fully meet the international advanced level. The design of flexible bearing has formed a set of complete theoretical system, of the product manufacturing process improvement, mature, the product quality is stable.

 
LYC series harmonic drive reducers special bearing reliable quality stable performance, has been successfully used in "shenzhou", series of spacecraft harmonic drive device, for our country's manned space to make the contribution.
