Abstract

The clutch effects transmission of rotation on two torque levels, one of which is adjustable. Exceeding the torque level results in slipping of the clutch.

Two Torque Spring Slip Clutch

The clutch effects transmission of rotation on two torque levels, one of which is adjustable. Exceeding the torque level results in slipping of the clutch.

Drive shaft 1 is rigidly mounted to inner sleeve 2 and outer sleeve 3. High torque spring 4 is wound around surface 5 of sleeve 3 and surface 6 of hub 7 which is rigidly connected to driven shaft 8. A high torque is transmitted by virtue of friction between spring 4 and surfaces 5 and 6.

The outer end 9 of spring 4 is connected to ring 10 which, during high-torque transmission, is in rotation with outer sleeve 3. If ring 10, however, is restrained against rotation, e. g., by arresting at one of the notches 11, spring 4 is unwound by outer sleeve 3 and brought out of action.

Under these conditions a low torque is transmitted by spring 12, fixed with its end 13 to inner sleeve 2 and wound around surface 14 of hub 7. Its friction is controlled by twisting inner and outer sleeves 2 and 3 against each other and biasing adjusting spring 15. This adjustment is locked by screw 16.
