<p>PURPOSE:To length the life of an electromagnetic coupler as well as prevent a biting phenomenon by projecting the friction transmission surface of a lining on an amateur side in the face to the end of a magnetic pole portion and making the injectional amount adjustable according to the wearing of the lining. CONSTITUTION:A gap adjusting part 8 is inserted into a magnetic pole portion 6 in the face of an amateur 4, and a notch 5a formed in a yoke 5 is coupled with a projection 8a formed on the gap adjusting part 8 in such a manner that it can not move in the turning direction but can move in the axial direction. The gap adjusting part 8 is fixed to the yoke 5 by means of a screw 8b and a nut 8c provided to the projection 8a of said gap adjusting part 8. Also, the friction transmission surface 9a of the lining 9 is beforehand fixed in such a way that it is projected from the magnetic pole portion 6.</p> |
