Principles of Transmission Technology
The Roller Driver transmission uses the arc surface indexing principle,which is currently the most accurate motion control method.The work plece is composedof an input shaft (curved index roller)and a roller (output shaft).The roller groovesurface on the input shaft meshes with the outer ring surface ofthe driven rollerelement on the roller in line contact,so that to drive the wheel (the worktable)torotate.The driven roller element utilizes internal roller bearings to transmit torqueduring rotation.This working principle guarantees zero backlash,excellent workingaccuracy and working efficiency,and effecively avoids the loss of intemal parts,and provides a lasting high-precision working state.
