Gear coupling is a common mechanical part for gear reducer to transmit torque. It consists of two parts, the active axis and the driven axis.
The lubrication of gear coupling:
1, Oil storage lubrication. The lubricating oil is fired by the nozzle, and the lubricating oil is kept in the outer circle of the gear by the centrifugal force when the lubricating oil is rotated.
2, Self flow lubrication. Lubricating oil is injected by the nozzle and flows through the gear backlash, which flows out from the sleeve hole. The main way of cooling is to cool down. The oil film is hard to form, and the gear surface wear is faster than the following strong lubrication.
