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) intended to be adapted to a clutch (11) in an engine starter, wherein the gear shaft (10) has an axially extending elongated cylindrical structure and comprises: helical flowers The key portion (101), which is close to the starter motor and has a helical spline structure external helical spline (1011) on its outer surface; wherein, the inside of the gear shaft (10) has an oil chamber (30), and at least one oiler (20) is arranged between the oil chamber (30) and the outer surface of the gear shaft (10). The invention also relates to a starter comprising a gear shaft (10) as described above. By adopting the gear shaft and the starter of the invention, the contact surface between the gear shaft of the vehicle engine starter and the overrunning clutch can be provided with lasting and effective lubrication, thereby improving the transmission efficiency and reliability of the vehicle starter.

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...
