The unique stability of cycloidal pin gear reducer can replace many impact transmission mechanisms to play a stable transmission role. Its characteristics are as follows: small quality, long life and easy maintenance. The cycloid reducer is a new type of deceleration equipment, which uses the basic principle of small tooth difference and large planetary transmission system. It can be widely used in manufacturing as a drive or deceleration device. The cycloidal pin gear reducer of the design scheme considers the dynamic model and design criteria, such as stable operation, load sharing of multi-tooth gear transmission and gearbox gear, to maintain high transmission efficiency and high load-bearing capacity. And it is very easy to manufacture. The cycloidal pin gear reducer used in this design has the advantage of simple design method. We can see from the analysis results that the performance index of the bearing is also fully in accordance with the use regulations. In this paper, the research paper discusses the following aspects of the pin wheel output pin-oscillating planetary transmission: First, the traditional method of designing the basic parameters of the pin wheel output pin-oscillating planetary transmission key components is referred to Design and calculation of basic parameters of planetary transmission. Second, the force calculation and analysis of the transmission system including the load of the support bearing and the arm bearing. Third, the final assembly drawings and key parts drawings are drawn using drawing software. Fourth, improve the life calculation and strength check of key parts and bearings such as studs and cycloid wheels.
