[0002] The compressor clutch pulley is an important part of the compressor power transmission system, which is responsible for transmitting power from the driving end to the driven end.
[0003] The traditional compressor clutch pulley has some shortcomings in structural design. First, its structure is often bulky and uses more materials and parts, which not only increases the manufacturing cost, but also leads to an increase in the overall mass, thus affecting the energy consumption and efficiency of the compressor. Secondly, the traditional compressor clutch pulley has obvious defects in dust prevention. Due to the lack of effective dust prevention design, the pulley is prone to inhaling dust and impurities during operation. These dust and impurities will accumulate inside the pulley. Over time, it will have an adverse effect on the operation of the pulley, causing the pulley to wear more and reduce its service life. In severe cases, it may cause the pulley to get stuck or fail, causing compressor failure. Therefore, a dustproof compressor clutch pulley is proposed to solve the above-mentioned problems.
