Abstract: To satisfy the increasing requirements of high-precision and zero-backlash transmission in the modern machine tools and industrial robots, a precision measurement method of roller enveloping hourglass worm tooth surface ...

Abstract: A systematic process of matrices-based wear profile modeling and a new optimization approach for planetary roller screw mechanism (PRSM) was proposed in this paper to improve the anti-wear performance with varied thread ...

Abstract: Due to the low error sensitivity, the local conjugate enveloping hourglass worm drive based on medium gear is being intensively investigated, and this article examines the local conjugate meshing performance of such a worm ...

Abstract: To avoid the negative influence of sliding contact, this paper tries to investigate the spiral bevels of pure-rolling contact that can be manufactured by existing manufacture technology. In this process, spatial conjugate ...

Abstract: The load distribution analysis plays a significant role in the performance evaluation of cycloid speed reducer. However, current analytical models usually ignore elastic deformation, clearances, or assembly errors. These ...
