In ancient times, wooden, copper and cast iron gears were all handmade.exist17end of the century,Precision gear machiningIt can be cut by forming methods, but cast iron technology is still the main method of gear machining.Since then, with the improvement of gear metal cutting level, the development of gear processing technology has been greatly promoted.In recent years, with the development of science and technology, people areMachining gearThe strength and load-carrying capacity of the gears have put forward higher requirements, and the precision gear processing and forming technology has emerged as the times require.Among them, the precision forging of bevel gears has become increasingly mature.

What are the types of precision gear machining?

According to the shape of the tooth profile and the shape of the tooth profile curve, the types of precision gear processing can be divided into involute gear transmission, cycloid gear transmission,Arc gearTransmission and parabolic wheel transmission.Involute gear transmission is widely used.

There are three main types of plasticity in precision gear machining: rolling and hammering deformation, corrugation and ridge extension.

In order to prevent the plastic deformation of the tooth surface, precision gear processing spiral bevel gears can be used to increase the hardness of the tooth surface and choose a higher viscosity lubricant.

The gear tooth surface of precision gear processing is abraded, and the high-power soft tooth surface gear is driven. When the lubrication condition is not good and the tooth surface is strongly friction, the precision spiral bevel gear is manufactured according to the order, and it is easy to produce glue damage on the tooth surface.When the damage is light, scratches and grooves along the sliding direction are formed on the feeding surface; when the precision gear processing damage is severe, the welding adhesion phenomenon of the tooth surface is formed due to the local high temperature.Although the plastic deformation of the tooth surface generally occurs on the tooth surface of soft and ductile metal, the failure of the plastic deformation of precision gear processing may also occur on the completely hardened and surface-hardened tooth surface.This is the result of the metal in the contact area being subjected to loads exceeding the yield stress.
