Gear processing equipment is a special machine used to manufacture various gears. Gears play a vital role in mechanical transmission, and are widely used in many fields such as automobiles, aerospace, machine tools, and construction machinery. The following is a detailed introduction to gear processing equipment:
1. Gear processing method and corresponding equipment
Milling teeth
Equipment: universal milling machine, gear milling cutter, etc.
Working principle: Use gear milling cutter to cut the gear blank on the milling machine. The shape of the milling cutter is similar to the shape of the tooth slot of the gear, and the tooth shape of the gear is gradually cut by rotating the gear blank and moving the milling cutter.
Features: low processing accuracy, suitable for single piece small batch production and repair work.
2.Gear hobbing
Equipment: Gear hobbing machine.
Working principle: The gear hobbing machine uses the meshing movement between the hob and the gear blank to simulate the meshing process of a pair of helical gears, so as to cut out the tooth shape of the gear. The rotary motion of the hob is the main motion, and the rotary motion of the gear blank and the axial feed motion are the auxiliary motions.
Features: high processing precision, high production efficiency, suitable for mass production.
3.Gear shaping
Equipment: Gear shaper.
Working principle: The gear shaper makes up and down reciprocating cutting motion on the gear blank through the gear shaper cutter, and makes meshing rotating motion without clearance with the gear blank, so as to cut the tooth shape of the gear.
Features: Suitable for machining internal gear, multi-coupling gear and sector gear, etc., high machining accuracy.
4.Gear shaving
Equipment: Shaving machine.
Working principle: The gear shaving machine uses the free meshing transmission between the gear shaving cutter and the gear being processed, and micro-cuts the gear tooth surface through the cutting edge of the gear shaving cutter to remove the burrs and trace metals on the gear surface, so as to improve the precision and surface quality of the gear.
Features: High processing efficiency, can significantly improve the precision and surface quality of gear, suitable for intermediate precision gear finishing.
5.Gear honing
Equipment: Gear honing machine.
Working principle: The gear honing machine uses the relative motion between the honing wheel and the gear to grind and polish the gear tooth surface in a small amount, so as to improve the precision and surface quality of the gear. The honing wheel is generally composed of abrasive and binder, and its shape is similar to the tooth shape of the gear.
Features: high machining precision, good surface quality, suitable for high-precision gear finishing.
6.Gear grinding
Equipment: Gear grinding machine.
Working principle: The gear grinding machine uses the relative motion between the grinding wheel and the gear to grind the gear tooth surface, thereby improving the precision and surface quality of the gear. The shape and size of the grinding wheel are selected according to the tooth shape and accuracy requirements of the gear.
