Low noise axial sleeve used for electromagnetic brake

Abstract

The invention discloses a low-noise shaft housing used in a magnetic brake, comprising a shaft housing body which is provided with teeth at the periphery, the peripheral surface of the shaft housing body is provided with a ring-shaped groove, and a rubber dentiform ring, which is matched with the ring-shaped groove, is embedded in the ring-shaped groove. A method for manufacturing the low-noise shaft housing used in the magnetic brake includes the following steps: arranging the ring-shaped groove on the peripheral surface of the shaft housing body 1; adopting a pouring way to manufacture the rubber dentiform ring with a diameter slightly smaller than that of the shaft housing body; sheathing the rubber dentiform ring in the ring-shaped groove of the shaft housing body to be matched with the ring-shaped groove, etc. The low-noise shaft housing overcomes the defects of the prior art, can maintain certain axial slippage and good radial torque transmission function after being installed, and can effectively reduce or eliminate noise as well; meanwhile, the low-noise shaft housing is easy to process and manufacture and has good wearing resistance and high temperature resistance.

Description

technical field [0001] The present invention relates to a shaft sleeve, and more particularly, the invention relates to a toothed shaft sleeve for an electromagnetic brake. Background technique [0002] At present, the gear sleeves used for electromagnetic brakes are all metal parts, the inner hole of which is connected with the rotating shaft of the motor, and the outer diameter is connected with the rotor of the electromagnetic brake. When the sleeve is installed in the electromagnetic brake, it is required to have a certain amount of axial sliding, and at the same time, it must also have the function of transmitting radial torque, so it is necessary to leave an assembly gap between it and the rotor, and the The existence of the gap causes unavoidable noise pollution during the use of the electromagnetic brake. For this reason, those skilled in the art have studied the noise elimination technologies such as "circlip-groove", "tooth-ball", "tooth (tooth side)-spring leaf",...

AI Technical Summary

Problems solved by technology

When the sleeve is installed in the electromagnetic brake, it is required to have a certain amount of axial sliding, and at the same time, it must also have the function of transmitting radial torque, so it is necessary to leave an assembly gap between it and the rotor, and the The existence of the gap causes unavoidable noise pollution during the use of the electromagnetic brake

For this reason, those skilled in the art have studied the noise elimination technologies such as "circlip-groove", "tooth-ball", "tooth (tooth side)-spring leaf", although these technologies can receive certain noise reduction. Noise effect, but inconvenient to process, wear resistance and high temperature resistance are not good
