Gear aligning device for lapping machine and gear aligning method

Abstract

The invention discloses a gear aligning device for a lapping machine. The gear aligning device comprises a driving box, a driving shaft, a fixed driven box, a driven shaft and a reciprocating mechanism, the driving shaft is connected with a motor through a transmission mechanism, the reciprocating mechanism comprises a connecting rod and a compound cylinder, the compound cylinder comprises a cylinder body, a guide sleeve and a piston rod, a radial partition plate with a central hole is arranged in the cylinder body and divides the cylinder body into a front main oil cavity and a rear accessory oil cavity, oil supply for the main oil cavity and the accessory oil cavity is respectively and automatically controlled by two proximity switches and a PLC (programmable logic controller), and the piston rod drives the driving box to move front and back to align teeth. The invention further discloses a gear aligning method. Machining efficiency is high, uniformity of grinding gear backlashes can be ensured, and gear lapping effects are improved.

Description

technical field [0001] The invention relates to a gear aligning device and a method of a gear grinder. Background technique [0002] The gear grinding machine is used for high-speed and precise grinding of gears. Its purpose is to properly correct the deformation of the gear heat treatment, improve the tooth surface finish, and improve the position and size of the tooth surface contact area, so as to reduce noise, improve transmission stability and load capacity. Purpose: At present, the gear alignment device of the gear grinding machine mostly uses a separate hydraulic cylinder to drive the active box to reciprocate to align the teeth. If a top tooth occurs, manual observation is required, and then the pinion is turned to eliminate the top tooth, and the processing efficiency is low; Grinding liquid is used during grinding, and there must be a backlash between the gear pairs, and ensuring the stability of the backlash has an important impact on the grinding effect. At pr...

Purpose: At present, the gear alignment device of the gear grinding machine mostly uses a separate hydraulic cylinder to drive the active box to reciprocate to align the teeth. If a top tooth occurs, manual observation is required, and then the pinion is turned to eliminate the top tooth, and the processing efficiency is low; Grinding liquid is used during grinding, and there must be a backlash between the gear pairs, and ensuring the stability of the backlash has an important impact on the grinding effect. At present, the backlash value can only be preset by the stroke of the hydraulic cylinder, but after the gear heat treatment There are deformations of different sizes, so the backlash value cannot be adjusted according to the current state of the actual grinding gear, and the consistency of the backlash of each group of grinding gears cannot be guaranteed, which affects the grinding effect
