Title:
SLIDING FRICTION DEVICE
Document Type and Number:
Japanese Patent JPS6081526
Kind Code:
A
Abstract:
PURPOSE:To obtain a contact state whose adhesive properties are high through heating of friction contact, by forming a constitution component in relation to a contact action of a friction contact mechanism of a shape memory alloy. CONSTITUTION:An armature 13 is constituted unitarily with a friction sliding contact component 14 on the side fronting on a rotor 6, a ferromagnetic component 15 for formation of a magnetic circuit between the rotor 6 and a stator 8 and the friction sliding contact component 14 is formed of a shape memory alloy. In this consequence, although the armature 13 is sucked to a rotor 6 side by electrifying a coil of the stator 8, high friction heat is generated between the sliding contact component 14 and the rotor 6 made of a shape memory alloy through a matter that a driving shaft 5 is rotating at high speed or that transmission of high torque is about to carry out. Then unevenness of a pattern is generated on the surface of the sliding contact component 14, and a friction coefficient between the sliding contact component 14 and the rotor 6 is improved instantaneously.
