Title:
MANUFACTURE OF ROTOR FOR ELECTROMAGNETIC CLUTCH
Document Type and Number:
Japanese Patent JP3252572
Kind Code:
B2
Abstract:
PURPOSE: To provide a rotor for an electromagnetic clutch where the number of part items is reduced, the positioning can be dispensed with, and the attracting force without the magnetic leakage is obtained by conducting the plastic working for an inner circumferential wall, an outer circumferential wall and a bottom part of one ring- shaped plate.
CONSTITUTION: When an electromagnetic coil 6 is electrified, the electromagnetic coil 6 generates the magnetic force to attract armature 4 to a rotor 3. The magnetic path as indicated by the dashed line α is formed. A connecting member 22 made of the non-magnetic material is connected between an inner circumferential wall 8 and a bottom part 11. Because the connecting member 22 and a friction material 13 which are made of the non-magnetic material are connected between the bottom part 11 and an outer circumferential wall 9, no magnetic flux is leaked between the inner circumferential wall 8 and the bottom part 11, between the bottom part 11 and a rotor, and between the bottom part 11 and the outer circumferential wall 9 in the rotor 3. Thus, an armature 4 is securely attracted to a friction surface 10a of the rotor 3. As a result, the rotational power of the engine to be transmitted to a pulley 2 through a V-belt is transmitted to an input shaft of a coolant compressor through the rotor 3, the armature 4 and a rotationally-driven body.
