Precision gear machiningIntroduction:

Gear edges have teeth that continuously mesh with mechanical elements that transmit motion and power.Gear is a kind of toothed mechanical parts that mesh with each other, and it has been used in gear transmission for a long time. At the end of the 19th century, the principle developed into the pick method and special machine tools and tools that used the principle to pick teeth appeared one after another. With the development of production, the stability of gear rotation was paid more attention.

Generally there are teeth, tooth spaces, end faces, normal faces, addendum circles, tooth root circles, base circles, and index circles

With the development of science, gears have gradually changed from metal gears to plastic gears.Because plastic gears are more lubricating and wear-resistant.Can reduce noise, reduce costs, and reduce friction.

Commonly used plastic gear materials include PVC, POM, PTFE, PA, nylon, PEEK, etc.

There are two types of involute gear processing methods.One is the profiling method, which uses a foam grinder to cut out the tooth grooves of the gears to "imitate the shape."The other is Fan Cheng Fa (Zhan Cheng Fa).

(1) Hob: can process helical teeth with less than 8 modules

(2) Milling machine scraping teeth: can process straight trucks

(3) Insert ring: internal teeth can be machined

(4) Cold stamping teeth: chip-free processing is possible

(5) Gear picker: can process large gears with 16 modulus

(6) Precision cast gear: can process a large number of cheap pinions

(7) Gear grinding of gear grinding machine: gears of precision mother machine can be processed

(8) Die casting machine casting teeth: processing multiple non-ferrous metal gears

(9) Gear shaving machine: a metal cutting machine for gear finishing
