Description

Technical Field

[0001] The utility model relates to the technical field of automobile gear ring processing, in particular to an automobile gear ring press-fitting tool. Background Art

[0002] The press-fitting process of an automotive flywheel ring gear is a meticulous and complex operation. First, the flywheel to be fitted with the ring gear must be secured to the workbench. The new ring gear is then heated to a desired temperature using a heating medium such as waste engine oil to expand its inner diameter. Once heated and expanded, the ring gear is quickly and vertically inserted onto the outer edge of the flywheel, ensuring a natural fit without misalignment or tilt. After the ring gear cools, it is inspected for proper installation and a natural fit.

[0003] However, the traditional press-fitting of the gear ring adopts the manual knocking method. The operator needs to manually knock the gear ring into the outer edge of the flywheel. Often, due to uneven force control, the force on the gear ring is unbalanced, making it impossible for the gear ring to fit completely with the flywheel after installation, resulting in local gaps or misalignment, which reduces the assembly accuracy and shortens the service life of the gear ring. It is also easy to have an adverse effect on the transmission efficiency and system stability in subsequent use. Utility Model Content

[0004] The purpose of the utility model is to provide a press-fitting tool for an automobile gear ring, so as to solve the problem that in the existing gear ring press-fitting process, the force on the gear ring is unbalanced due to uneven control of the operator's force, which affects the fit between the gear ring and the flywheel, reduces the assembly accuracy, and shortens the service life of the gear ring.
