The frictional heat energy was concentrated on the thermal effect layer with the thickness of 4 mm, The temperature gradient of contact surface is the highest, and decreased rapidly with the radius direction of the lining's groove. The temperature gradient and TEL's thickness increased with the increasing of the sliding speed. The temperature decreased rapidly with the radius direction and also with the increasing of center angle of the lining's groove. The sliding speed and distance are obtained under two sliding conditions when the lining fails, which supply the theoretical basis with the antislip design of friction hoist.
