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.
