The Roller Driver transmission uses the arc surface indexing principle, which iscurrently the most accurate motion control method. The work piece is composed of an input shaft (curved index roller)and a roller (output shaft). The roller groove surface on the input shaft meshes with the outer ring surface of the driven rollerelement on the roller in line contact, so that to drive the wheel (the worktable) to rotate. The driven roller element utilizes internal roller bearings to transmit torque during rotation.This working principle guarantees zero backlash,excellent workingaccuracy and working efficiency,and effectively avoids the loss of internal parts,and provides a lasting high-precision working state.
