Abstract

PURPOSE:To increase the transmission torque of an electromagnetic clutch in an early stage of use by a simple treatment and to hold it in a stable state thereafter by applying magnetic grains and nonmagnetic grains in a mixed state on transmission/friction faces. CONSTITUTION:Mixture consisting of Fe magnetic grains and SiC nonmagnetic grains with average grain diameter about 0.5mum is manually applied on transmission/friction faces 14a, 32a. As a result, the transmission/friction faces 14a, 32a remarkably increase their catching resistances through the mutual bite of grains themselves due to the interposition of both grains, specially high hardness nonmagnetic grains, infiltrating into the recesses of those surfaces. Improvement in fight adhesion property due to the interposition of, principally, the magnetic substance filling up the gaps at interfaces makes molecular force very strong and also decreases the leak of magnetism produced due to the gaps at the interfaces to reinforce magnetic flux, i.e. electromagnetic attracting force. Such operations can remarkably improve the transmission torque of an electromagnetic clutch in an early state of less familiarized use, and also this condition can be maintained in a stable state thereafter.
