Description

Technical Field

[0001] This utility model belongs to the field of auxiliary measuring device technology, and more specifically, relates to a clutch chuck clearance gear matching instrument. Background Technology

[0002] An air conditioning electromagnetic clutch typically includes components such as a pump body, pump shaft, pulley, electromagnet, and suction cup. The suction cup is attracted by the electromagnet and comes into contact with the friction drive surface of the pulley. The compressor is driven by electromagnetic force and the friction between the two surfaces. However, due to issues with machining and installation precision, the clearance between the suction cup and the friction drive surface of the pulley varies in each clutch. Shims need to be added during installation to adjust this clearance. Currently, there is no measuring tool to directly measure this clearance. Generally, a dial indicator and some auxiliary tools are used to measure the values, and then the actual clearance is calculated before selecting a shim of appropriate thickness. However, existing measuring tools have limitations in reference and measurement accuracy, leading to errors in the required clearance. Therefore, a convenient measuring and calculation tool is needed. Utility Model Content
