    A shaft connecting mechanism is provided between a slip-on hub and a power takeoff shaft by means of a control ring which extends around the slip-on hub and which is formed to have a pressure screw extend through a threaded bore therein, the pressure screw engaging against a clamping wedge in the slip-on hub which is formed with a trapezoidal configuration generally conforming with the configuration of an axiallly extending groove formed in the slip-on hub. Blocking members are arranged in radial apertures in the slip-on hub and pockets are formed in the control ring. The pressure screw when angularly aligned with the clamping wedge, places the control ring in the locked position and when the pressure screw and the clamping wedge are angularly unaligned, the blocking members enter the pockets in the control ring.

    The invention relates to transport engineering, in particular, to shaft connections, mainly drives a drive shaft with a shaft for selecting the power of a tractor or a similar machine.
    The aim of the invention is to prevent backlash in the circumferential direction and to increase the reliability of the axial locking of the connected shafts.

Concentricly, the sleeve 1 is set to a control — 25 liters of ring 2, which can be rotated between two boundary positions. The control ring 2 is spring-loaded in the circumferential direction by a torsion spring 3 and has deaf radially directed pockets k on the inner surface. In the sleeve 1 is made through radial holes 5 in which are installed radially movable locking elements 6, made in the form of balls. On the splined section of the shaft 7 is filled with an annular groove. The locking elements 6 are installed with the possibility of contact with the surface of the annular groove of the shaft 7 and the pockets 4. On the inner surface of the sleeve 1 in the area of the slot is made a groove 8 of the trapezoidal profile, extending towards the control ring 2. On the outer 40

    its coil, and rigidly connected with the key 10 and the control ring 2. The ends of the spring in one of the mutual positions of the sleeve 1 and the ring 2 can contact each other or with the bottom of the groove along the surface of the coil. The key 10 can be set relative to the axis of the slot of the shaft 7 with an offset in the direction opposite to the direction of main rotation. The pressing force acting on the key can be transmitted through an intermediate element 14, made in the form of a ball. With this arrangement, the pressure screw 12 is installed in an axial hole made in the control ring 2, and the end of the screw in contact with the ball 14 is conical.
    The connection shaft works as follows.
    8, the free position, the thrust screw 12 is reversed and allows the rotation of the control ring 2 between two boundary positions, i.e. the receiving pockets k of the ring 2 are located in the zone of the radial holes 5, which ensures the release of the locking elements 6 from the groove of the power takeoff shaft 7 (Fig. 3).
    In the locked position (Fig. 2}, the locking elements 6 are located in the annular groove of the shaft 7 and are fixed against radial movement of the inner surface of the control ring 2. The key 10 is tucked in by the screw 12 and eliminates play in the circumferential direction of the sleeve 1 on the power take-off shaft 7. the position of the pockets 4 is coordinated with the angular position of the screw 12 in such a way that in the position of one hundred
    the surfaces of sleeve 1 are knocked out radially, the pockets are always displaced from the right-directed nest 9 intersecting the groove 8. In the groove 8 there is a key 10 in the keystone profile that contacts one of its inclined faces with the side surface of the shaft of the shaft being connected 7 "Control ring 2 is made with a threaded hole 11 in which the pressure screw 12 is installed with the possibility of radial movement and contact with the large base of the key 10. In the control ring 2, an annular rim is also made on its inner surface az 13 in which is installed 50

    The radially directed socket 9, jointly with the screw 12, performs the function of a turn stop. The ends of the torsion spring 3 in the locking position are in contact with each other, limiting the further rotation of the control ring.
    In the free position, the spring 3 rests on the inner wall of the groove 13, which also prevents further rotation of the ring 2.
