Summary: | The utility model relates to the technical field of precursor automobile differential mechanisms, in particular to a durable differential mechanism used for precursor gearbox. The durable differential mechanism used for precursor gearbox aims at solving the problem that a positioning pin is prone to being cut off after a planet gear shaft is ground and corroded or the size is too large when the planet gear shaft is axially positioned outside a differential mechanism shell in planet gear shaft axial positioning modes of an existing precursor automobile differential mechanism. A first half-axle gear and a second planet gear of the durable differential mechanism are in meshed connection with a first planet gear and a second planet gear respectively. A first snap spring groove is formed in the position, close to the end face of the first planet gear, of the middle of a plant gear shaft. A second snap spring groove is formed in the position, close to the end face of the second planet gear, of the middle of the plant gear shaft. A first snap spring is connected in the first snap spring in a sleeved mode. A second snap spring is connected in the second snap spring in a sleeved mode. On the premise that limitation of the axial position of the planet gear shaft is guaranteed, the grinding corrosion fault of the planet gear shaft is completely eradicated, and meanwhile the outline size and overall weight of the differential mechanism are reduced. |
