  Principle of cycloidal pinwheel reducer: The cycloidal pinwheel reducer is a novel transmission device that applies the principle of planetary transmission and adopts the meshing of cycloidal needle teeth.The entire transmission device of the cycloidal pinwheel reducer can be divided into three parts: input part, deceleration part and output part.A double eccentric sleeve with a displacement of 180° is installed on the input shaft, and two roller bearings called swing arms are installed on the eccentric sleeve to form an H mechanism. The center holes of the two cycloids are the upper swing arm bearings of the eccentric sleeve. In order to reduce the friction, in a reducer with a small speed ratio, the cycloidal wheel meshes with a set of circularly arranged needle teeth on the needle gear to form an internal meshing reduction mechanism with a tooth difference of one tooth. , Needle tooth sleeve is attached to the needle tooth).When the input shaft rotates with the eccentric sleeve, due to the characteristics of the upper tooth profile curve of the cycloidal gear and the limitation of the needle gear on the needle gear, the motion of the cycloidal gear becomes a plane motion with both revolution and rotation. When the input shaft rotates in the forward direction, the eccentric sleeve also rotates once, and the cycloidal wheel rotates one tooth in the opposite direction to obtain deceleration. Then, with the help of the W output mechanism, the low-speed rotation motion of the cycloidal wheel is transmitted to the output shaft through the pin shaft. In order to obtain a lower output speed.

1. Features of cycloid reducer:
  1) High-speed ratio and high-efficiency single-stage transmission can achieve a reduction ratio of 1:87, and the efficiency is above 90%. If multi-stage transmission is adopted, the reduction ratio will be greater.
  2) Compact structure and small size. Because of the planetary transmission principle, the input shaft and output shaft are on the same axis, so that the size of the model is as small as possible.
  3) Smooth running and low noise. Cycloid needle teeth have a large number of meshing teeth, a large overlap coefficient and a mechanism of mechanical balance, so that vibration and noise are limited to a minimum.
  4) Reliable use and long life. Because the main parts are made of high-carbon chromium steel, they are quenched (HRC58-62) to obtain high strength, and part of the transmission contact uses rolling friction, so it is durable and has a long life.
  5) Reasonable design, convenient maintenance, easy disassembly and installation, minimum number of parts and simple lubrication, so that the cycloid reducer deeply gains the trust of users.
