[0002] The car starter is an important part of the car engine. It is responsible for converting the battery's electrical energy into mechanical energy, driving the engine flywheel to rotate, and starting the engine. In order to meet the torque and speed requirements of the starter when starting the engine, planetary gears are usually used in car starters for transmission.

[0003] During the production and processing of planetary gears, the burrs generated during the gear processing need to be eliminated to ensure the accuracy and smooth operation of the gears. There are many ways to remove burrs, but for components with more complex structures such as planetary gears, special methods are required to remove burrs. Among them, flexible physical grinding methods such as the Smank abrasive flow process can efficiently and thoroughly remove the burrs on the internal teeth of planetary gears while maintaining the accuracy of the gears.

[0004] A common deburring mechanism for the production and processing of planetary gears for ultra-precision automobile starters requires the gear to be placed inside a tooling during deburring with a Smank abrasive flow, and then the abrasive flow is connected for grinding. However, in order to ensure the grinding effect, the opening size of the tooling is close to the gear, making it easy to put the gear into the tooling but difficult to take it out. In view of this, the present application proposes a deburring mechanism for the production and processing of planetary gears for ultra-precision automobile starters. Utility Model Content
