Tool and method for measuring static torque of flywheel assembly

Abstract

The invention relates to a tool for measuring static torque of a flywheel assembly. The tool is characterized by comprising a tool fixing base (1), a gear (6) and an adjusting device, wherein the gear (6) is fixedly arranged on the tool fixing base (1) through a gear fixing seat (7); the flywheel assembly (5) is arranged on the tool fixing base (1), and the adjusting device is used for adjusting the relative position of the flywheel assembly (5) and the gear (6) to guarantee gear mesh of a gear ring on the flywheel assembly (5) with the gear (6); the adjusting device comprises slide guide rails (2), a positioning block (3) and a thrust bolt (4), the flywheel assembly (5) is arranged on the slide guide rails (2) through a flywheel fixing seat (8) and can slide along the slide guide rails (2), and the thrust bolt (4) is arranged at one end of each slide guide rail (2) through the positioning block (3); one end of the thrust bolt (4) cooperates with the flywheel fixing seat (8) for work, so that the position of the flywheel fixing seat (8) on the slide guide rails (2) is adjusted.

Description

technical field [0001] The invention belongs to the technical field of tooling for manufacturing automobile engines, and in particular relates to a tooling for measuring the static moment of a flywheel assembly and a measuring method thereof. Background technique [0002] The main function of the engine flywheel assembly is to provide sufficient moment of inertia for the engine, so that the engine can pass through the compression top dead center smoothly, and it is also an indispensable component for engine power output, starting the engine and obtaining engine signals; The speed of the small engine fluctuates, and the engine runs more smoothly, that is, the NVH of the whole vehicle is reduced. [0003] The flywheel assembly consists of a flywheel body, a flywheel ring gear and positioning pins. The flywheel body and the flywheel ring gear are joined by interference fit, which is mainly to shrink fit the flywheel with the flywheel ring gear after processing. Since the flywh...

Problems solved by technology

[0004] Generally, a special torque measuring machine is used to measure the static torque of the flywheel assembly, which is characterized by relatively expensive equipment, used for mass production, and low flexibility. When changing, the torque measuring machine needs to be modified, and the cost of the modification is relatively high. Usually, the torque measuring machine is mainly used by flywheel manufacturers.
