Electromagnetic clutch and method of manufacture |
摘要 |
An electromagnetic clutch includes a pair of rotatable driving and driven members adapted to be electromagnetically coupled together and uncoupled from each other. At least one of the driving and driven members comprises a pair of concentric annular members both made of magnetizable material and having opposed and radially spaced peripheral surfaces in which annular grooves are formed, respectively. An annular bond member of a non-magnetizable material is swaged into the annular space between the annular magnetizable members and thus into the annular grooves to mechanically connect the magnetizable members as well as to magnetically disconnect them from each other.
