Problems solved by technology

At present, there are generally two types of planet carrier structures: one is the integral type, and the integral planet carrier is formed in one piece. It needs to process multiple planet wheel cavities in the circumferential direction of the planet carrier. During the processing, it is not easy to clamp Positioning, the processing technology is complicated, and the processing is difficult; the other is welding type. The welding type planetary frame is to divide the planetary frame into two independent planetary frame parts, and the two planetary frame parts are processed separately, and then the two planetary frame The parts are welded into one body, the welding process needs to be positioned, and there is a temperature change during the welding process, which affects the overall accuracy. The planetary carrier currently used is connected to the drive shaft through a spline. The planetary carrier cannot be directly connected to the gear and other transmission components. The planetary carrier Can not achieve the ratchet brake function

Abstract

The invention relates to a planet carrier, wherein a planet carrier main body comprises two planet carrier members, the two planet carrier members are independent monomers, the two planet carrier members are connected to the planet carrier main body, the two planet carrier members are detachably connected, the two planet carrier members are fixedly connected through bolts, so that the two planet carrier members are conveniently detached and installed, and the two planet carrier members can be respectively processed, the two planet carrier members are connected through bolts after being respectively processed, so that the processing is easy, the processing precision is high, and the processing technique is simple, one planet carrier member can be fixedly connected with a gear, a sleeve supporting part is arranged on the other planet carrier member, and such transmission components as gears can be arranged on the sleeve supporting part, so that the planet carrier can realize more transmission functions, and ratchet teeth are arranged on one planet carrier member to be matched with the other components to brake the planet carrier.

Description

[0001] This application is a divisional application with the application number 201010131106.7, the application date of March 24, 2010, and the title of the invention "a planet carrier and its processing technology". technical field [0002] The invention relates to a supporting device for a transmission, in particular to a processing method for a planet carrier, and belongs to the field of machinery. Background technique [0003] Planetary carriers are commonly used in transmissions and their transmission mechanisms and play an important role. With the continuous improvement of vibration, noise and transmission accuracy, the requirements for the design and processing of planetary carriers are also getting higher and higher. At present, there are generally two types of planet carrier structures: one is the integral type, and the integral planet carrier is formed in one piece. It needs to process multiple planet wheel cavities in the circumferential direction of the planet car...
