Explanation on the structural characteristics of planetary cycloid reducer

planetCycloid reducerIt adopts cycloidal pin-tooth meshing and planetary transmission principle.This kind of reducer is a supporting reducer for machinery manufacturing units such as power generation, chemical industry, metallurgy, cement, winemaking, grain, food processing, construction, environmental protection, pharmaceuticals, mining, petroleum, tobacco, transportation, textile, lifting, and steel.

Principle of planetary cycloid reducer: The transmission of gears is completely realized by two eccentric wheels.A double eccentric sleeve dislocated by 180° is installed on the input shaft, and two roller bearings are installed on the eccentric sleeve to form an H mechanism. The center hole of the two cycloidal wheels is the raceway of the arm bearing on the eccentric sleeve, and The cycloidal wheel is meshed with a group of annularly arranged needle gears on the needle gear to form a small tooth difference internal meshing deceleration mechanism. In order to reduce friction, in the reducer with a small speed ratio, the needle teeth are provided with needle gear sleeves.When the input shaft rotates with the eccentric sleeve for one week, due to the characteristics of the tooth gallery curve on the cycloid wheel and the limitation of the needle teeth on the needle gear, the movement of the cycloid wheel becomes a plane movement with both revolution and rotation. When the input shaft rotates for one round, the eccentric sleeve also rotates one round, the cycloid wheel rotates in the opposite direction through a tooth difference to obtain deceleration, and then with the help of the output mechanism, the low-speed autorotation motion of the cycloid wheel is transmitted to the output shaft through the pin shaft , so as to obtain a lower output speed.But its allowable input speed range is very low.The cycloidal pinwheel can generally be integrated with the planetary gear, and its reduction ratio can be very large.
