Overload Release Clutch

An overload release clutch can be constructed to permit translatory as well as rotational motion, by providing grooves for the drive rollers parallel to the rotational axis.

Referring to the figures, hub 1 is the driving member and has secured thereto a split coupling with two halves 2a and 2b. The driven member is shaft 3 having integral therewith an enlarged shoulder 4 having a pair of diametrically opposite grooves 5 parallel with the shaft axis. Shaft 3 also has an annular groove 6 engaged by a U-shaped reciprocating element 7 for translating shaft 3 axially.

Each coupling half 2 has resiliently secured thereon a drive cap 8. Each drive cap 8 is mounted on its respective coupling half by cap screws 9 and springs 10 urging the drive cap toward the coupling.

Each drive cap 8 also supports a roller 11 mounted for rotation on shaft 12. Shafts 12 may be retained by a press fit in the respective caps or in the rollers. The caps 8 are guided for movement toward and away from the coupling halves by pins 13, each fixedly mounted on the coupling halves 2.

Between each drive cap 8 and its respective coupling half are mounted for axial reciprocation, a pair of slides 14 urged away from the coupling and hub by springs 15. Each slide 14 is provided with a cam surface 16 which is effective to aid in further urging the drive caps 8 outwardly after being moved a predetermined distance from the coupling half 2.

In operation, hub 1 is rotated carrying co...
