Abstract
The utility model discloses an electromagnetic clutch. The electromagnetic clutch comprises a magnet yoke body. Armatures are arranged on the magnet yoke body. The portions, corresponding to the armatures, of the magnet yoke body shrink inwards in the axial direction, wherein the shrinking distance equals to the axial width of the armatures. The armatures are welded to the magnet yoke body. A permanent magnet coil is arranged in the magnet yoke body and is connected with the magnet yoke body through a coupler. The permanent magnet coil is provided with a bent portion, wherein the edge curvature of the radial section of the bent portion equals to the edge curvature of the radial section of the coupler. The two ends of the bent portion extend to the inner side of the center of the permanent magnet coil to form bent sections. The center end faces, facing towards the permanent magnet coil, of the bent sections are opposite to the end face of the magnet yoke body. An internal gear sleeve is arranged in the permanent magnet coil. A plurality of through grooves are formed in the inner wall of the internal gear sleeve, wherein the width of the grooves ranges from 1 mm to 2 mm. According to the electromagnetic clutch, the radial width of the whole magnet yoke body is shortened, raw materials are saved, stability of installation is effectively ensured, and the service life of the electromagnetic clutch can be prolonged to a certain extent; meanwhile, safety is good, and the installation method is flexible.
