Inspection and maintenance of hard gear reducer

Cycloid pinwheel deceleration and all transmission devices can be divided into three parts: input part, deceleration part and output part. The input shaft is equipped with a 180 ° offset double eccentric sleeve, and two roller bearings called the rotating arm are installed on the eccentric sleeve to form a roller table of H mechanism and the central holes of the two cycloidal wheels are the bearings of the rotating arm on the eccentric sleeve. In the reducer with small speed ratio, the needle teeth are equipped with a needle gear sleeve to reduce friction. When the input shaft rotates for one circle with the eccentric sleeve, due to the characteristics of the cycloid's upper profile curve and its limitation by the pinions, the cycloid's movement becomes a plane motion with both revolution and autobiography. When the input shaft rotates for one circle, the eccentric sleeve also rotates for one circle, and the cycloid turns a tooth in the opposite direction to obtain deceleration. Then, with the help of W output, the low-speed rotation movement is transmitted to the output Shaft for a lower output speed.
