The typical structure of the cycloidal planetary reducer, which consists mainly of four parts:

(1) The planetary frame consists of an input shaft and a double eccentric sleeve, and the eccentric sets of eccentric sets are 180 degrees.
(2) planetary wheel, also known as cycloid, the tooth profile is usually short outside the Cycloidal reducers of the inside of the equidistant curve. According to the requirements of the movement, a planetary wheel can be driven, but in order to make the input shaft to achieve static balance and improve the carrying capacity, for a tooth difference pin pendulum drive, often with two identical odd teeth of the planetary wheel Transmission is not subject to this limit), installed in the double eccentric sets, two rounds of position just 180 degrees difference. A roller bearing (called a boom bearing) is fitted between the planetary wheel (cycloidal wheel) and the eccentric sleeve to reduce friction. In order to save radial space, rolling bearings usually use roller bearings that do not have outer race The pinhole surface of the variable gear motor is directly used as a raceway. In recent years, the structure of the optimized design of the double eccentric sleeve and the bearing made of a whole, said the overall double eccentric bearing.
(3) Central wheel, also known as hypoid gearbox wheel, needle shell with a set of needle pin, usually pin pin is also equipped with needle sets.
(4) Output mechanism This is often used pin-type output mechanism.
