Abstract

A gear milling spindle box directly driven by a torque motor is characterized by comprising the low-speed high-torsion torque motor (1), a driving synchronous belt pulley axle (3), a first driving synchronous belt pulley (4), a second driving synchronous belt pulley (8), a spindle box body (9), a motor support (21), a first synchronous belt (10), a second synchronous belt (20), a disc milling cutter (11), a driven synchronous belt pulley axle (14) and a cutter bar (15). The low-speed high-torsion torque motor is directly connected with the disc milling cutter by the tensioned synchronous belts with arc teeth, a transmission path is short, and transmission efficiency is high. In addition, the tensioned synchronous belts can realize stable transmission without backlashes, nonlinear vibration of a transmission system due to fluctuating cutting load is avoided, cutting noise is lowered, surface roughness of a cut tooth surface is improved, and the risks of impact pitting corrosion of the tooth surface during gear transmission are avoided.

Description

technical field [0001] The invention relates to gear machining equipment, in particular to a torque motor direct-driven milling spindle box of a cylindrical gear numerical control milling machine. Background technique [0002] Large cylindrical gears are widely used in mechanical transmission in mining, metallurgy, chemical industry and other industries, and are very important basic parts of mechanical manufacturing. The traditional method of machining large cylindrical gears usually adopts hobbing or slotting, which is very inefficient. In recent years, with the technological development of numerical control technology, cutting tool technology and other related fields, the process of milling large gears with numerical control forming gear milling machines has been gradually popularized and applied. The CNC forming gear milling machine is equipped with a forming disc milling cutter with non-regrinding blades, and uses the non-instant center envelope method to directly mill ...
