Claims (1)

[Scope of utility model registration request] An annular input side gear 1 is rotatably supported on a bearing 2 supported by an internal support 4 and an external support 5 coupled to an output shaft 11, and a disk 6 is attached to the cylindrical portion of the external support 5 so as to be able to freely come into contact with and separate from the internal support 4. spline fitting to the inner circumference of input side gear 1,
A lining 3 that can freely slide between the external support 5 and the disk 6 is provided, and a return spring 7 that presses the disk 6 against the internal support 4 is provided, and a yoke 16 that accommodates the coil 17 is fixed to a fixed part, and the internal support Sleeve bearing 14 in the cylindrical part of 4
An armature 15 is provided to be able to slide freely through the coil 17, and when the coil 17 is not energized, a gap is maintained between the armature 15 and the yoke 16.
When the coil 17 is energized, the armature 15 is attracted to the yoke 16, and its end face presses the disk 6 against the lining 3 via the presetting ball 19 against the elasticity of the return spring 7, and the lining 3 is connected to the disk 6 and the outside. In the electromagnetic clutch or electromagnetic brake that is clamped to the support 5, the internal support 4 and the disk 6 are connected via thrust generating balls 20 held in respective conical holes. Electromagnetic clutch or electromagnetic brake.
