Abstract

551,892. Slipping-clutches. SULZER FRERES SOC. ANON. Sept. 11, 1941, No. 11638. Convention date, Nov. 8, 1940. [Class 80 (ii)] A clutch which slips upon overload comprises friction plates 8 splined to a drum 6 fixed to a gear wheel 2 and co-acting friction plates 5 splined to a spider 4, the plates 5, 8 being pressed together by annular members 10 under the action of springs 11. A pair of axially movable concentric rings A, B engage one another by inclined teeth 13, 14 and are splined to a hub 3 on a shaft 1 and to the spider 4 respectively by teeth 17 .. 20. In operation, torque is transmitted to the spider 4 from the shaft 1 through the rings A, B which, due to the inclined teeth 13, 14, tend to separate the annular members 10. If the torque exceeds a predetermined amount the members 10 move apart and the clutch plates 5, 8 slip. To prevent overheating of the parts easily fusible material 9 is inserted between some of the plates 5, or the friction surfaces may be of such material. Heating up of the dutch then causes the fusible material to be melted and discharged whereupon the annular members 10 are pressed against the side faces of the spider 4, the clearance between the clutch members being great enough, due to the escape of the fusible material, to prevent further clutch engagement. Instead of an easily fusible material a material which breaks up into small particles upon a rise of temperature may be used. The teeth 13, 14 may be axial and the teeth 17 ... 20 inclined.
