Problems solved by technology

This causes increased friction between the gear shaft and the overrunning clutch or other components
[0003] In addition, after a period of operation, the lubricating oil on the gear shaft also tends to pick up dirt or material fragments worn off from the various components, so that an undesired mixture may also form on the surface of the gear shaft
This can also lead to increased friction and eventually the starter will fail

Abstract

The invention relates to a gear shaft (10). The gear shaft is used for matching with a clutch in an engine starter, wherein the gear shaft (10) comprises an axially extended elongated circular column structure and a spiral spline part (101), which is near a starter motor and comprises a spiral spline structure that is an en externally spiral spline (1011) on the external surface; wherein, an oil chamber (30) is arranged in the gear shaft (10), and at least one oil filer (20) is arranged between the oil chamber (30) and the external surface of the gear shaft (10). The invention also relates to a starter of the gear shaft (10). The gear shaft and the starter are used in order to provide lasting and effective lubrication for a contact surface between the gear shaft of the vehicle engine starter and an overrun clutch, and transmission efficiency and reliability of the vehicle starter are improved.

Description

technical field [0001] The present invention relates to the field of vehicle engines, and more specifically, relates to a gear shaft capable of ensuring effective lubrication on the outer surface of the gear shaft while driving, and also relates to a starter comprising the aforementioned gear shaft . Background technique [0002] A starter is often included in a vehicle engine, which is configured to drive the engine flywheel to rotate through the rotation of an electric motor. The electric motor typically outputs torque and rotates through an overrunning clutch (ORC for short) and a gear shaft (or pinion shaft) that are nested with each other. When the starter starts running, the motor drives the overrunning clutch and the gear shaft, and the gear shaft tends to move in a direction away from the motor relative to the overrunning clutch. During this process, the lubricating oil or grease on the gear shaft tends to separate from the surface of the gear shaft under the actio...
