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 and a processing technology. The planet carrier body comprises two planet carried members which are separate individuals. The two planet carrier members form the planet carrier body through connection and are detachable connected; since the two planet carrier members are fixedly connected through bolts, the two planet carrier members are convenient for disassembly and assembly, and can be respectively processed and then be connected through the bolts, one of the planet carrier members can be fixedly connected with gears, the other planer carrier member is provided with a sleeve supporting part on which transmission parts such as gears are arranged so as to lead the planet carrier to achieve more driving functions; and one of the planet carrier members is provided with ratchet gear teeth which can be matched with other parts to achieve the brake of the planer carrier. The invention has the advantages of easy process, high processing precision and simple processing technology.

Description

technical field [0001] The invention relates to a supporting device for a transmission, in particular to a planet carrier and its processing technology, and belongs to the field of machinery. Background technique [0002] 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 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 divid...
