Embodiment Construction

[0009] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0010] see figure 1 , a transmission bushing for reducing the operating noise of an electromagnetic disc brake, comprising a bushing body 1, meshing teeth are arranged on the outer peripheral surface of the bushing body 1, a noise-reducing coating 2 is provided on the meshing teeth, and a noise-reducing coating 2 It is obtained by coating functional materials such as nylon T66, nylon T6 or nylon T1010. This embodiment utilizes the characteristics of elasticity, wear resistance and high temperature resistance of the functional material forming the noise reduction coating to ensure a certain amount of axial sliding and radial torque transmission between the transmission sleeve and the friction plate rotor.

[0011] This embodiment adopts the s...

Abstract

The invention discloses a driving sleeve for reducing the running noise of an electromagnetic disc brake. The driving sleeve comprises a shaft sleeve body of which the peripheral surface is provided with engaged teeth; and a noise reduction coating is coated on the engaged teeth and is a nylon 66, nylon T6 or nylon T1010 coating. The invention also discloses a manufacturing method for the driving sleeve. The manufacturing method comprises the following steps of: 1) performing sand blasting on the shaft sleeve body; 2) performing electrostatic coating on the shaft sleeve body subjected to sand blasting, and forming the noise reduction coating on the surface, wherein a paint is any of nylon 66, nylon T6 or nylon T1010 powder; 3) hanging the driving sleeve with the noise reduction coating into an oven, and heating and molding the driving sleeve; 4) taking the driving sleeve out of the oven, and naturally cooling the driving sleeve; and 5) reshaping the engaged teeth provided with the noise reduction coating on a press machine by using a push broach. The driving sleeve has the functions of damping and reducing noise to fulfill the aim of quiet operation of the brake, also can improve the wear resistance of a rotor of a friction plate, and prolongs the service life of the brake.

Description

technical field [0001] The invention relates to a shaft sleeve and a manufacturing method thereof, in particular to a transmission shaft sleeve for reducing the running noise of an electromagnetic disc brake and a manufacturing method thereof. Background technique [0002] With the application of brakes and brake motors more and more widely, some industries, such as stage technology, elevators, and military industry, have put forward higher and higher requirements for them. However, due to the existence of radial clearance between the rotor and the bushing, the traditional brake inevitably generates noise during operation. In order to reduce the above noise, CN100595449C on March 24, 2010 disclosed a low-noise bushing used for electromagnetic brakes, which consists of a bushing body with teeth on its outer periphery, and the outer peripheral surface of the bushing body is provided with The annular groove is embedded with a rubber toothed ring matching the annular groove.
