Experimental investigation into the implications of transmission errors for rack-and-pinion drives

Abstract Rack-and-pinion drives are the preferred option in machine tool sector when long ranges of motion and high loads involved. However, their shortcomings particularly include deficiencies achievable positioning path accuracy. The backlash as one main issues is well described literature numerous solutions to reduce its negative effects exist. In contrast, there a lack regarding scientific systematic analysis transmission errors rack-and-pinion drives. this paper, displacements originating drive train system with industrial components measured under different operating conditions. observed thoroughly analyzed no-load operation sources discussed. Subsequent investigations show significant load-dependent alterations direction-dependent characteristics, causes which explained. It shown, that negatively affect accuracy position controlled drives, amplified by excitation structure certain To address issue, error compensation concepts presented.
