Rotary table in market mainly includes 4 kinds of mechanism that is worm gear, roller cam, DD driver and harmonic structure. The following is the introduction:
1.Worm Gear: It's one of the most popular structrue in NC rotary table because of its irreversibility and costs.The worm is generally made of bronze, but the wear resistance is poor. In order to improve the service life, some manufacturers use the alloy steel.
2.Roller Cam: This is the most popular deceleration mode in the Chinese market. Compared with worm gear, it has many advantages, such as wear resistance, high transmission efficiency , good price and basically no maintenance. Chinese consumers like it very much.
3.DD Motor: It's the most efficient rotary table with the highest precision. It has the highest precision because it has no mechanical structure, which is directly driven by motor , no reducer. It has high technical difficulty and high price. It is generally used for five axis machine tools.
4.Harmonic Driver: Harmonic reducer is a new transmission structure in gear reducer. It uses flexible gear to produce controllable elastic deformation and cause relative staggered teeth between rigid wheel and flexible wheel to transmit power and motion. This kind of transmission is essentially different from the general gear transmission, and has particularity in meshing theory, set calculation and structural design.
