Abstract
Description
Technical Field
[0001] The utility model specifically relates to the technical field of motor shells, in particular to a vibration-absorbing and noise-reducing motor shell. Background Art
[0002] The motor housing is the core component of the motor. During the use of the motor, the problems often encountered are vibration, noise, and heat dissipation, especially in high-speed rotation mode. The vibration of the motor will cause the motor housing to vibrate together. The harm caused by the motor vibration may be the extrusion and friction between the parts, which may cause the parts to be scrapped; the friction of the parts may cause noise, which will aggravate the noise pollution of the equipment.
[0003] Chinese utility model publication number CN 213585417 U discloses a vibration-damping and noise-reducing motor housing, wherein the housing of the motor housing is divided into an upper housing and a lower housing, and first fixing parts are arranged on the left and right sides of the upper housing and the lower housing, and a plurality of threaded mounting holes are arranged on the first fixing part, and the upper housing and the lower housing are fixedly connected by bolts; a plurality of positioning grooves are also arranged on the first fixing part, and a plurality of limiting cylinders are arranged in the positioning grooves, and replaceable colloid gaskets are placed in the positioning grooves, and the thickness of the colloid gaskets is greater than the depth of the positioning grooves, and a blind hole is arranged at the bottom of the colloid gaskets, and the limiting cylinders and the blind holes are arranged in multiple rows of staggered positions, and the housing cooperates with the stator bracket, and a second fixing part is arranged on the left and right sides of the stator bracket, and the second fixing part is arranged as a positioning plate extending to the outside of the stator core, and the second fixing part is located between the positioning grooves of the upper housing and the lower housing, and the colloid gasket is used to clamp the positioning plate;
[0004] The above-mentioned shock-absorbing and noise-reducing motor housing reduces vibration and noise by adding a rubber gasket between the upper shell and the lower shell. However, when the whole vibrates, the vibration is easily transmitted to the base, which cannot effectively reduce the noise. For this reason, we provide a shock-absorbing and noise-reducing motor housing, which absorbs the noise generated by the sound-absorbing cotton on the inside, and reduces shock through the upper and lower rubber gaskets on the bottom, and cooperates with the shock-absorbing rod and spring contraction to further buffer and reduce shock, thereby effectively compensating for the above-mentioned problems.
