FLEXWAVE Strain Wave - Harmonic Gear Unit from Nidec Shimpo

 

Take your robot to the next level with FLEXWAVE. NIDEC-SHIMPO has a history of supplying the leading robotics and machine tool manufacturers in Japan. NIDEC-SHIMPO's loyal customers within these industries strongly urged them to develop our harmonic gear technology and leverage our primary competencies modularity and flexibility of the core design and highly consistent production in mass volume to help them become more competitive in the global marketplace. After an extensive effort to refine harmonic gear technology and to manufacture at a level that exceeds customer expectations, NIDEC-SHIMPO has released FLEXWAVE.

FLEXWAVE is a compact harmonic gear reduction mechanism that achieves zero backlash, as well as exceptional positioning accuracy, torque density and repeatability. FLEXWAVE consists of three internal elements the flexspline, the circular spline and the wave generator. The elasticity properties of the flexspline and the teeth differential between the flexspline and the circular spline result in its unique reduction characteristics.

FLEXWAVE comes in various form factors, including component sets, simple contained assemblies, and complete gear units. Cup, hat, solid, and hollow input shaft configurations give engineers true freedom in design. FLEXWAVE is also available in Ultra-Flat and High Torque variations for applications with demanding footprint and performance requirements. Dimensions are interchangeable against industry standards, making them easier to implement in legacy equipment. When compared with other gear technologies, FLEXWAVE offers the following advantages:
