Abstract

The invention makes it possible to simplify the manufacturing technology of a device for automatically connecting and disconnecting shafts. The clutch contains two coaxial coupling halves in the form of sleeves 1 and 2, inside which is located the driving sleeve 3. On its outer surface there are rollers 4 with two annular grooves 7 and 8, the axes of which are offset relative to the axis of the roller and are diametrically opposed. Between the clips and rollers, the jamming bodies are placed in the form of balls 11 and 12. Depending on the direction of rotation of the sleeve, balls 11 or balls 12 are wedged between the corresponding roller groove and the holder, transferring the rotation to one side or the other on the holder. 1 3. p.

Description

The invention relates to mechanical engineering.

The aim of the invention is to simplify the manufacturing technology of the coupling elements.

FIG. 1 shows the proposed coupling axial section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

Dual reversible freewheel clutch contains two coaxial driven ball seizure

coupling halves in the form of sleeves 1 and 2, freely mounted on the hubs of the leading coupling half, made in the form of sleeve 3 and rollers 4, evenly spaced on the outer surface of sleeve 3. Roln are installed in pairs and are interconnected by rings 5 and 6. Each roller 4 is made two annular grooves 7 and 8, the axes of which are eccentric to the axis of roller 4 and are diametrically opposite to each other between the annular groove 9 of the yoke 1 and the grooves 7 of the wedging rollers 4 (FIG. 3) and, simultaneously, the gap S between the annular groove 10 of the yoke 2 and the balls 12 (FIG. . 2) and clearance between these balls 12 and the groove 8 of the rollers 4 (Fig. 1). The transmission of torque from the sleeve 3 to the holder 1 occurs. The holder 2 has the opportunity to freely rotate in any direction relative to the sleeve 3. When worn. On the inner surface of the clips, changing the direction of rotation of the sleeve 3

annular grooves 9 and 10 are filled, the radius of which is equal to the radius of the jamming bodies made in the form of balls 11 and 12. Each ball is located simultaneously s ring grooves of two adjacent rollers 12 and 12 are wedged between the ring groove 10 of the yoke 2 and grooves 8 of the rollers 4 and simultaneously the balls 11 are wedged between the annular groove 9 of the holder 1 and the groove

forks and clips. The surfaces of the grooves of each of the rollers 4 provide the necessary rear of a pair of rollers symmetrically relative to the radial plane passing through the center of the ball. In cages 1 and 2 mounting holes are made.

the gap between THIS annular groove and the balls 11 and the gap between these balls 11 and the groove 7 of the rollers 4 (not shown). A torsional monapod example of a closing, threaded, outlet, g ment sleeve 3 to the clip 2 is transferred. The clip 1

running into treadmills for mounting balls 11 and 12 (not shown). The magnitude of the eccentricity e from the grooves 7 and 8 of the rollers 9 is chosen in such a way that, in the course of free movement of one of the clips, the balls will not be able to rotate freely in any direction relative to the sleeve 3.

The proposed dual reversible freewheel clutch ensures that the ring grooves 9 and 10 fall, i.e. 35 the increased reliability due to the fact that the gap S was less than the depth of the treadmills 9 and 10. The details of the dual reverse freewheel clutch can be made of polymeric or wood-polymer materials.

The installation of the dual reversible one-way clutch is carried out as follows.

Initially, jammed rollers 4 are arranged in pairs in cylindrical bags, tying the rollers together by rings 5 and 6. Then, the bag is placed on the outer surface of sleeve 3, while rollers 4 are positioned so that their axes of rotation and axis of rotation of the grooves 7 and 8 lay on the same line (horizontal) and the surfaces of the grooves 7 and 8 were arranged in the same way. After ;-) on both sides of the sleeve 3, the sleeves 1 and 2 are put on the hubs and fixed against axial mixing. Next, through the mounting holes in the clips 1 and 2, the balls 11 and 12 are installed in the grooves 7 and 8 of the rollers 4 arranged in pairs, after which these holes securely close.

the views of the skewing of the bodies of wedging, as well as the manufacturability of manufacturing the leading half-coupling due to the performance of its composite of parts having cylindrical surfaces.

Claims (2)

1. Dual reversible clutch of free stroke, containing a leading coupling half, covering its two coaxial driven coupling halves and jamming bodies, placed in the gap between the driving coupling and the driven coupling coupling, characterized in that, in order to simplify manufacturing technology, jamming is made in the form of balls, and the leading coupling half is in the form of a sleeve and in pairs located on its outer surface of the rollers, each of which is made with two annular grooves, the axes of which are eccentric to the axis of the roller and are located diametrically ivopolozhno, each ball is placed simultaneously on two adjacent grooves The removal of the dual reversing freewheel is performed in the reverse order. Dual reversible freewheel works as follows. When the sleeve 3 rotates clockwise, the rollers 4, due to the forces of friction, begin to rotate in the opposite direction, moving the balls 11 and 12 located in the grooves 7 and 8 and providing ball seizure between the annular groove 9 of the yoke 1 and the grooves 7 of the wedging rollers 4 (FIG. 3) and, simultaneously, the gap S between the annular groove 10 of the yoke 2 and the balls 12 (FIG. 2) and the gap between these balls 12 and the flute 8 of the rollers 4 (Fig. 1). The transmission of torque from the sleeve 3 to the holder 1 occurs. The holder 2 has the opportunity to freely rotate in any direction relative to the sleeve 3. When the direction of rotation of the sleeve 3 changes Similarly, the balls 12 are wedged between the annular groove 10 of the sleeve 2 and the grooves 8 of the rollers 4 and, simultaneously, balls 11 are wedged between the annular groove 9 of the holder 1 and the groove the gap between THIS annular groove and the balls 11 and the gap between these balls 11 and the groove 7 of the rollers 4 (not shown). Torsional transmission is made possible to rotate freely in any direction relative to the sleeve 3.
