Description

Tooling for machining planet carrier and machining method thereof

Technical Field

The invention belongs to the field of planetary gear machining, and particularly relates to a planetary carrier machining tool and a planetary carrier machining method.

Background

A planetary gear transmission refers to a gear transmission in which the axis of one or more gears revolves around the fixed axis of another gear. The planet wheel not only rotates around the axis of the planet wheel, but also rotates around a fixed axis along with the planet carrier. The sun gear, the planet carrier and the internal gear are all rotatable about a common fixed axis and are coupled to other components which are the three basic elements of such a train to withstand the applied torque. If the three components are not fixed, the angular speeds of the two components need to be given when the mechanism moves, and the transmission is called a differential gear train; if the internal gear or the sun gear is fixed, the planetary gear train is called. Both of these gear trains are commonly referred to as planetary gear drives.

The planet carrier is one of the main components of the planetary gear transmission device, and the planet wheel shaft or the bearing is arranged on the planet carrier. When the planet wheel is used as a basic component, the planet wheel is the part which bears the largest external moment in the mechanism. The structural design and manufacture of the planet wheels has a great influence on the load distribution among the planet wheels, so that the bearing capacity, noise, vibration and the like of the transmission device are greatly influenced.

Traditional planet carrier course of working generally directly can accomplish through pouring the reverse mould, nevertheless in practical application because fashioned planet carrier corner unevenness behind the reverse mould appears the unstable problem of installation easily in later stage installation, and then influences planetary gear's rotation, consequently for the stability of guarantee follow-up installation, need carry out certain processing of polishing to pouring fashioned planet carrier.
