Processing technology and dynamic balance fixture of flywheel assembly for diesel engine

Abstract

The invention discloses a diesel engine flywheel assembly processing technology and a dynamic balancing fixture, comprising the following steps: step 1: rough turning the small end face of the flywheel; rough turning the large end face of the flywheel; step 2: adopting a fan-shaped special fixture to clamp on the largest outer circumference of the flywheel surface, the small end face of the flywheel of the fine car meets the design requirements; Step 3: Use a fan-shaped special fixture to clamp the outer circumferential surface of the installation place of the flywheel ring gear on the flywheel, and the large end face of the flywheel of the fine car meets the design requirements; Step 4: Process the large end face of the flywheel and the flywheel Each hole on the small end face; Step 5: Process the sensor hole on the outer peripheral surface of the flywheel; Step 6: Shrink fit the ring gear; Step 7: Perform dynamic balance detection and deduplication process and detection process; the flywheel assembly is supplied in the form of an assembly, It can greatly improve the quality of the dynamic balance of the flywheel assembly; the tension head of the dynamic balance fixture acts on the inverted conical surface, and the tension flaps are expanded outwards, making full use of the downward axial force to increase the joint degree of the positioning surface and improve the dynamic Balance detection accuracy.

Description

technical field [0001] The invention relates to a processing technology of a flywheel assembly. Background technique [0002] The flywheel is a cast iron inertia disc with a large mass. It stores energy and supplies the demand of the non-power stroke, so as to ensure the uniformity of the inertial rotation of the engine crankshaft and the uniformity of the output torque. The dynamic balance detection is the consideration of the processing accuracy of the flywheel. a key indicator of . However, the flywheel exists in the form of components in the complete machine. The flywheel parts are transported to the complete machine factory, transferred to the sub-assembly line, pressed into the ring gear, and then transferred to the complete machine assembly line. This affects the dynamic balance quality of the flywheel components, and the logistics of the sub-assembly line Turnover leads to potential quality hazards such as potential bumps on the friction surface of the flywheel, whi...
