Abstract

PURPOSE:To prevent a brake ring from transforming and waving against frictional heat and to attain the prevention of dust scattering and the promotion of braking effect by providing radial and circumferential grooves on the sliding surface of a brake ring. CONSTITUTION:In this device, an essentially annular brake ring 2 is provided in the lower side of a rotor 1 to be rotated in one body with the rotor 1, and under the ring 2, a brake 3 supported by a thrust bracket 4 is arranged to face to with a dust-collecting cover 5 around. Here, on the sliding surface 2A of the above-written brake ring 2, radial heat-radiating grooves 6 and circumferential thermal-transformation-preventing grooves 7 are provided respectively in a required number. In this construction, when the rotor 1 is braked by the sliding friction between the brak 3 and the brake ring 2, the heat by the sliding friction can be radiated from the heat radiating grooves 6, and the waving or the transformation of the brake ring 2 by the sliding heat can be absorbed by the thermal-transformation-preventing grooves 7.
