Abstract
A mutual-lapping device and mutual-lapping method for improving processing precision based on the principle of error averaging is proposed. The device including driving friction wheel, driving belt pulley, transmission belt A, connecting rod A, rotation shaft segment A, multi-ball sleeve, mutual-lapping gear A, tension spring, driven friction wheel, pendulum bar of the driven friction wheel, driven belt pulley, transmission belt B, connecting rod B, pressure spring of tensioning pulley, tensioner mechanism, rotation shaft segment B and mutual-lapping gear B. By mutual lapping the high-precision gears, not only the pitch deviation, tooth profile deviation, helix deviation and runout can be reduced synchronously, but also the machining cost is low. Meanwhile, the effect of improving pitch accuracy, profile accuracy, helix accuracy and runout accuracy and reducing surface roughness is remarkable.
