Embodiment Construction

[0006] Clean up the oil stains and rust on each assembly part first, and then carry out sequential assembly: use a gasket selection machine to measure the inner cavity of the differential case, detect the required planetary gear gaskets and side shaft gear gaskets, and place the side gears respectively , Side gear spacers, planetary gears and planetary gear spacers, and planetary gear shafts are installed in the inner cavity of the differential case. Use a special measuring device to measure and adjust the gap between the planetary gears and the side gears. When turning the side gears There must be no stagnation or looseness. Apply thread locking agent to the bolt thread, fasten the driven gear to the differential case by the bolt to the specified torque, and use special tools to press the differential bearing into the differential. The two ends of the gearbox housing are rolled out into products.

Abstract

An automobile differential assembly assembly process, which is characterized in that the oil stains and rust on each assembly part are cleaned first, and then sequential assembly: use a pad selection machine to measure the inner cavity of the differential case and detect the required planetary gears Gaskets, side gear spacers, respectively put the side gears, side gear spacers, planetary gears and planetary gear spacers, and planetary gear shafts into the inner cavity of the differential case, and use a special measuring device to measure and adjust the planetary gears When turning the side gear, there must be no sticking or loosening. Apply thread locking agent to the bolt thread, and the bolt will fasten the driven gear to the differential case until According to the specified torque, special tools are used to press the differential bearings into the two ends of the differential housing, and then the products are rolled off the assembly line. The gap between the planetary gear and the side gear is stable, the product consistency is good, the precision is high, the pass rate is high, the production efficiency is high, the cost is low, the operation is simple, and it has a wide range of popularization and application value.

Description

technical field [0001] The invention relates to a mechanical assembly method, in particular to an assembly process of an automobile differential gear assembly. Background technique [0002] The automobile differential assembly is a transmission component installed inside the automobile reducer housing, which consists of a differential case, planetary gears, side gears, planetary gear shafts, driving gears, driven gears, planetary gear gaskets, half Shaft gear gaskets and differential bearings. The gap between the planetary gears and the side gears must be strictly controlled to ensure that no jamming occurs during operation. In the traditional assembly process, the measurement, selection and assembly of the planetary gear gasket and the side shaft gear gasket are all manually operated, the accuracy is low, and it is difficult to control the accuracy of the gap between the two, which affects the differential. The assembly quality of the assembly is unstable and the first pas...
