Problems solved by technology

The reason is that when the planetary bevel gear rotates on the cross shaft journal, there is a relatively high relative speed and friction between the cross shaft journal and the cylindrical surface of the inner hole of the planetary bevel gear, and it is difficult for the lubricating oil to form on the friction surface. Effective lubrication, and the lubricating oil on the friction surface is difficult to replenish in time after it is consumed, it is easy to directly cause rapid wear or ablation of the cross shaft journal and the mating surface of the planetary gear, causing movement disorders

Abstract

The invention relates to a cross shaft with spiral line oil storage grooves and a differential mechanism, and relates to the technical field of transmission speed change walking systems. The spiral line oil storage grooves are formed in the cylindrical surfaces of four shaft necks of the cross shaft; the differential mechanism comprises a right shell and a planetary bevel gear; the differential mechanism further comprises the cross shaft with the spiral line oil storage grooves; each shaft neck of the cross shaft is divided into two sections; one outward section is inserted in a correspondinghole of the right shell; and the other section is sleeved with the planetary bevel gear. According to the cross shaft with spiral line oil storage grooves and the differential mechanism, the spiral line oil storage grooves are formed in the cylindrical surfaces of the shaft necks of the cross shaft, the lubricating performance between the planetary bevel gear and the cross shaft is improved.

Description

technical field [0001] The present application relates to the technical field of transmission variable speed walking system, in particular to a cross shaft and a differential with a helical oil storage tank. Background technique [0002] The car drive axle is located at the end of the transmission system, its main function is to increase the torque transmitted by the drive shaft or transmission, and at the same time distribute the torque to the left and right driving wheels or the front and rear axles, so that the left and right driving wheels or the front and rear axles have the driving force of the car. Differential function required by kinematics. The differential function is mainly realized by the differential. When the differential is working, the planetary gears of the differential not only revolve around the center line of the half shaft, but also rotate themselves. [0003] The planetary bevel gear rotates around the centerline of the cross shaft journal of the diff...
