DETACHABLE COUPLING DEVICE FOR TORQUE TRANSMITTING SHAFTS

摘要

A coupling device comprises a conical coupling element on one shaft which is inserted into a tapered opening in the end of a yoke element extending from a universal joint connected to another shaft. The outer surface of the conical element has an annular groove in which are positioned two semi-circular blocking members pivotally mounted on the open end of the yoke element and having bent ends extending outwardly through openings in the yoke element. Spring means urge the blocking members inwardly into the groove to retain the coupling elements in driving relationship. A protective housing surrounding the conical coupling element has a lever pivotally mounted thereon which is operatively connected to a cylindrical slide element having an inner conical surface engageable with the projecting ends of the blocking members to release the blocking members from locking engagement with the conical coupling element.
