Abstract

Disclosed is a novel forklift pump drive shaft. The novel forklift pump drive shaft comprises a drive shaft body and a spline sleeve. The drive shaft body comprises a first section portion, a second section portion, a third section portion and a fourth section portion. One end of the first section portion is connected with the second section portion, and the other end of the first section portion is connected with the third section portion. The suspension section portion of the second section portion is connected with the fourth section portion. External teeth are arranged on the circumferential surface of the third section portion, and external splines are arranged on the circumferential surface of the fourth section portion. The spline sleeve is fixedly connected to the exterior of the drive shaft body in a sleeving mode, an inner cavity is formed inside the spline sleeve, the inner cavity and the spline sleeve are coaxially arranged, and internal splines which are matched with the external splines are arranged on the wall portion of the inner cavity.

Description

technical field [0001] The invention relates to a forklift pump drive shaft. Background technique [0002] Traditionally, the internal and external splines of the pump drive shaft are processed as a whole. Generally, the stroke of the internal spline slotting machine is not enough. Because the product itself is relatively slender, the rigidity during processing is poor, and the cumulative error of gear shaping and division is large, and the processing accuracy is difficult. ensure. After continuous exploration, our company designed a pump drive shaft that is easy to process, and successfully adopted the method of separate processing, anti-carburization during heat treatment, and then welding, which improved the processing efficiency, ensured the processing accuracy of the product, and saved production costs. . Contents of the invention [0003] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a new type of forklift p...
