Description

Technical Field

[0001] This utility model belongs to the field of gear shafts, and relates to a gear shaft, and particularly to a self-lubricating gear shaft. Background Technology

[0002] A gear shaft is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque, or bending moment. It consists of a gear and a shaft as a whole, and the different sections of the shaft can have different diameters.

[0003] When installing gears, manufacturers install oil reservoirs inside the gear shaft to continuously replenish oil to the gear. The oil reservoir melts the grease inside the reservoir when the gear is working to provide lubrication. However, the oil reservoir is usually fixed to the gear shaft, making it inconvenient to disassemble and replace the gear shaft. At the same time, it is difficult to determine the amount of grease remaining in the oil reservoir.

[0004] For example, a gear shaft with application number 202322411082.6 includes a shaft body, a gear part sleeved on the shaft body, a positioning ring on the shaft body, a positioning ring sleeved on the other side of the gear part, an oil reservoir rod fixedly inserted into the positioning ring, and a fixing plate installed on the positioning ring to fix the positioning ring, the gear part and the positioning ring together, and a fixing bolt connected to the fixing plate.

[0005] In the aforementioned patent, the oil reservoir stores grease, which melts due to high temperature and outputs oil to the outside of the gear when the gear shaft is working. However, since the oil is liquid, it will leak even when the gear stops without a seal, resulting in frequent replacement of the oil reservoir. In addition, replacing the oil reservoir requires disassembling the fixing plate and positioning ring, making the replacement process cumbersome. Utility Model Content
