Numerical control machine for lapping spiral bevel gear

Abstract

The invention discloses a numerical control spiral bevel gear lapping machine, which comprises a bed piece, an upright post, a driving headstock, a driven headstock, and a numerical control system, wherein the bed piece is provided with a driving guide rail and a driven guide rail, the upright post is arranged on the driving guide rail, and an automatic moving mechanism is arranged between the bottom of the upright post and the bed piece; the driving headstock is laterally suspended at the side surface of the upright post, and the bottom of the driving headstock is provided with an automatic moving mechanism; the driven headstock is arranged on the driven guide rail on the bed piece, and an automatic moving mechanism is arranged between the bottom of the driven headstock and the bed piece;the driving headstock and the driven headstock are provided with a driving spindle and a driven spindle respectively, and inner holes of the driving spindle and the driven spindle are provided with adriving gear and a driven gear respectively. The numerical control spiral bevel gear lapping machine has the advantages that the numerical control spiral bevel gear lapping machine has a compact structure, ensures that an operator can furthest approach workpieces, automatically recognizes teeth and adjusts the mounting distance and the side clearance of a bevel gear pair, adopts an electric spindle technology to realize the zero transmission of the revolution of the two spindles and improve the speed and maintain the dynamic stability at high speed, and has high production efficiency.

Description

technical field [0001] The invention relates to a numerically controlled bevel gear grinding machine, in particular to a numerically controlled spiral bevel gear grinding machine. Background technique [0002] The CNC spiral bevel gear grinding machine is used for high-speed and precise grinding of spiral bevel gears and hypoid gears. Its purpose is to correct the deformation of the gear heat treatment, improve the tooth surface finish, improve the position and size of the contact area, and achieve stable transmission. Reduce noise and improve carrying capacity. The processing method is to install a pair of bevel gears on the two corresponding main shafts of the gear grinding machine, and maintain a certain side clearance, and at the same time grind the large and small wheels in the axial direction and offset distance. ~50Nm braking torque, and add a certain flow rate and pressure of grinding fluid to the meshing point of the two wheels, and grind until the tooth surface tu...
