Planet carrier introduction

The planet carrier is one of the main members of the planetary gear transmission, the planet wheel shaft or bearing mounted on a planet frame. When a planet wheel as a basic component, it is the moment of maximum parts bear mechanism. The structure design and manufacture has great influence on transmission capacity, noise and vibration on the load distribution of each of the planetary wheels so that the planetary wheel.

Planet carrier feature

Reasonable structure of planetary frame should be light in weight, good rigidity,convenient processing and assembly. The common structural form of bilateral platetype, side plates separated and unilateral plate three. Bilateral plate integral rigidity.This structure if the whole forging, machining quantity is very large, and can therefore be used casting and welding method to get the structure and size of the blank tofinished products, but should pay attention to eliminate casting or welding defects and stress, may cause deformation or side will affect the strength, the machining quality and the use of the planet carrier at. Bilateral plate separated relatively complicated structure is mainly used to drive the condition of small. Because when the planet wheeldiameter is small, a planetary wheel bearing arranged on the planetary frame are both side plates, the outer diameter of addendum circle diameter is larger than the planet carrier gear; planetary frame side aperture is less than the sun wheel center.
