Production process for engine flywheel

Abstract

The invention discloses a production process for an engine flywheel. The production process is characterized by comprising the following steps: (1) producing a flexible disc; (2) producing a gear ring; (3) machining a mesh gear on an outer side of the gear ring through a gear hobbing machine; (4) hotly pressing and assembling the flexible disc and the gear ring; (5) checking; (6) cleaning; (7) finally checking. Therefore, the quality of a flywheel assembly is greatly improved, production steps are reduced, and the production efficiency is improved.

Description

technical field

[0001] The invention relates to the field of flywheel manufacturing, in particular to a production process of an engine flywheel. Background technique

[0002] The flywheel is the key starting part of the automobile engine. It is generally a thick disc. Its weight and balance performance seriously affect the performance of the engine. Therefore, it has certain weight requirements and certain dynamic balance requirements. With the improvement of automobile engine performance requirements, the requirements for flywheel dynamic balance also increase accordingly.

[0003] The traditional flywheel assembly consists of a flywheel disc, a flywheel ring gear, and a triangular support plate. The flywheel ring gear is shrunk onto the flywheel disc to form a flywheel tray assembly. The flywheel disc has rectangular teeth for transmitting speed signals. The flywheel disc Connected with the engine crankshaft, the torque is transmitted to the triangular support pad, and t...
