Embodiment Construction

[0009] The present invention as figure 1 shown.

[0010] The automobile air conditioner clutch pulley noise reduction structure includes a pulley 1, and a friction plate 2 is arranged on the outer friction surface of the magnetic isolation groove of the pulley 1.

[0011] Specifically, a ring groove matching the size of the friction plate is processed on the friction surface of the pulley (not on the magnetic isolation groove), and a high-temperature curing adhesive is applied to the friction plate, and it is baked at 180°C for 1.5 hours and cooled to room temperature, and then finishing the friction surface, friction plate and bearing hole. Through improvement, the air-conditioning clutch suction noise is reduced by 15-20 decibels, and the use of friction plates increases its service life by 20%.

Abstract

The invention provides an automobile air-conditioning clutch belt pulley noise reduction structure which comprises a belt pulley, wherein a friction piece is arranged on the friction surface outside a magnetism partitioning groove of the belt pulley. The automobile air-conditioning clutch belt pulley noise reduction structure utilizes the wearing resistance and the buffer property of the friction piece, the noise of the belt pulley is reduced to be less than 60-65 decibels, the service life is prolonged by 20% when the noise is reduced, and the reliability is improved.

Description

technical field [0001] The invention relates to an automobile air conditioner clutch, in particular to an automobile air conditioner clutch pulley noise reduction structure. Background technique [0002] At present, there is no friction pair between the pulley and the suction cup in the scroll type automotive air-conditioning clutch assembly. It is steel-to-steel contact, and the suction noise reaches 80 decibels. This structure does not meet the market demand, and the friction between steel and steel will There are adverse phenomena such as reduced lifespan, inconvenient maintenance and reduced reliability. Contents of the invention [0003] In order to prolong the service life of the vortex automobile air conditioner clutch and reduce the friction noise between the pulley and the sucker, the present invention proposes a noise reduction structure for the pulley of the automobile air conditioner clutch. [0004] Therefore, the technical solution of the present invention i...
