DEVICE FOR CONNECTING SHAFT WITH BUSH Russian patent published in 1998 - IPC

FIELD: mechanical engineering; machine elements. SUBSTANCE: device for connecting shaft 1 with bush 2 includes keys 3 and 4 received by slots of bush 2. Surfaces of these keys are engageable with flats of shaft 1. Slots and flats are formed by cylindrical surface; keys 3 and 4 are made in form of regular cylinders whose axes are parallel to axis of shaft. Axes of keys are located on cylindrical surface 5 of engagement of shaft and bush. Keys are locked against axial displacement by means of flat disk 6 provided with end round seats 7 engageable with projecting ends of keys 3 and 4. EFFECT: simplified construction and facilitated manufacture at reduced concentration of stresses in bush slots and at shaft flats. 2 cl, 2 dwg
