Abstract
A slip coupling comprised of a hub with extending flexible vane(s). The vane(s) extend from the hub at an acute angle which allows them to flex when coming in contact with a relatively rotatable friction cylinder. The friction between the vane(s) and the friction cylinder creates resistance to movement. Relative motion between the hub and friction cylinder occurs only when the frictional force between them is overcome.
Claims20
A two piece slip clutch comprising:
- an inner rotary member having a hub with an outer diameter formed by at least one flexible member which is attached to said hub and extends radially outward from said hub at an acute angle;
- an outer member having a cylindrically shaped inner diameter smaller than said outer diameter of said flexible member such that said flexible member must flex inward when positioned inside of said outer member and when the outer member is subjected to an overload condition, said inner rotary member can rotate in relation to said outer member and wherein the flexible memeber engages the inner diameter of the outer member at a point spaced from the end of the flexible member so that as the flexible member wears it will expand outwardly and the torque will not change substantially.
A two piece slip clutch comprising:
- a rotary member having a flexible member which is attached to a hub and extends axially from said rotary member at an acute angle from said rotary member;
- a second member positioned generally concentric and axially aligned with said rotary member such that said flexible member must flex when positioned against the face of said second member whereby when said rotary member is subjected to an overload condition, said rotary member can rotate relative to said second member and wherein the flexible memeber engages the inner diameter of the outer member at a point spaced from the end of the flexible member so that as the flexible member wears it will expand outwardly and the torque will not change substantially.
