Cycloid pin gear reducer is a novel transmission device which applies the principle of planetary transmission and adopts cycloid pin tooth meshing. All transmission devices of cycloidal pinwheel reducer can be divided into three parts: input part, deceleration part and output part. The input shaft is equipped with a double eccentric sleeve with a dislocation of 180 °, and the eccentric sleeve is equipped with two roller bearings called the rotating arm to form the H mechanism. The center holes of the two cycloid wheels are the raceway of the rotating arm bearing on the eccentric sleeve, and the cycloid wheel is meshed with a group of annular needle teeth on the needle gear to form an internal meshing reduction mechanism with a tooth difference of one tooth, (in order to reduce friction, in the reducer with small speed ratio, the needle tooth is equipped with a needle tooth sleeve).

Brief introduction of cycloid pinwheel reducer: when the input shaft rotates with the eccentric sleeve for one cycle, due to the characteristics of the tooth profile curve on the cycloid gear and its limitation by the needle teeth on the needle gear, the motion of the cycloid gear becomes a plane motion with both revolution and rotation. When the input shaft rotates forward for one cycle, the eccentric sleeve also rotates for one cycle, and the cycloid gear rotates one tooth in the opposite direction to obtain deceleration, and then with the help of W output mechanism, The low-speed rotation motion of the cycloid wheel is transmitted to the output shaft through the pin shaft, so as to obtain a lower output speed.

Characteristics of cycloidal pinwheel reducer: it can achieve high reduction ratio of 1:87 and high efficiency single-stage transmission of more than 90%. If multi-stage transmission is adopted, the reduction ratio is greater. The reduction ratio of primary transmission is 9 ~ 87, the reduction ratio of dual transmission is 121 ~ 5133, and the multi-level combination can reach tens of thousands. Moreover, the needle tooth meshing system has sleeve rolling friction, and the meshing surface has no relative sliding, so the primary reduction efficiency is 94%. Compact structure and small volume. Due to the planetary transmission principle, the input shaft and output shaft are on the same axis line, so that the model can obtain the smallest size as possible. Stable operation, low noise, large number of meshing teeth of cycloid needle teeth, large overlap coefficient and the mechanism of machine part balance limit the vibration and noise to a minimum. During operation, the number of teeth in contact at the same time is large, the coincidence degree is large, the operation is stable, the overload capacity is strong, the vibration and noise are low, and the noise of models of various specifications is low. Reliable use and long service life. Because the main parts are made of bearing steel, high strength is obtained after quenching treatment (hrc58 ~ 62), and some transmission contacts adopt rolling friction, so they are durable and long service life. Because the main parts are quenched by bearing steel (HRC58-62) and then finely ground, and the cycloid teeth are meshed with the needle gear sleeve and transmitted to the needle teeth to form a rolling friction pair, the friction coefficient is small, so that there is no relative sliding in the meshing area and the wear is very small, so it is durable. Reasonable design, convenient maintenance, easy disassembly and installation, minimum number of parts and simple lubrication make the cycloid pin gear reducer deeply trusted by users. Compared with other reducers with the same power, the weight and volume are more than 1 / 3 smaller. Due to the planetary transmission, the input shaft and output shaft are on the same axis to obtain the smallest size as possible.
