Description

one

The invention relates to the field of mechanical engineering and can be used, for example, in spring-loaded machines or devices for measuring the cutting of wires.

Knuckle couplings for transmitting rotation are known, with shutdowns, containing two coupling halves with mutually interlocking face cams, one of which is spring-loaded, is installed with the possibility of axial movement and is connected to the "depilar case by means of rolling elements.

In order to obtain a predetermined number of revolutions, a bracket is mounted on the fixed holder in the proposed coupling on a fixed holder, on which are fixed storage tanks filled with rolling bodies made in the form of balls, which one after another rotate during rotation into the wedge half made in the coupling half and move along a radial an annular groove provided on the ends of the half-coupling and cage facing one another before falling out of the window made in the cage, the number of revolutions per cycle being determined by the number of balls.

FIG. 1 shows the proposed coupling in operating condition; on fit. 2 is a section along A-A in FIG. one; in fig. 3 is a view along arrow B of FIG. 2; in fig. 4 shows a section along BB in FIG. 2

The clutch consists of a drive shaft 1 installed in the brackets and a coaxial shaft 2 aligned with it. Both shafts are equipped with coupling halves 3 and 4, for example, a cam shaft. The drive shaft is placed in the fixed frame 5, which serves simultaneously as shaft 1 for the shaft 1

slip. The shaft 1 is mounted with the possibility of axial movement, and in the non-working state it moves to the position corresponding to the open position of the coupling half, under the action of the spring-loaded pusher 6. On

The holder 5 is rotatably mounted to the holder 5, which is fixed in certain positions by means of a clamp 8. At least two storage containers 9 are mounted on the bracket (in the simplest case, tubes), the necessary number of balls 10 is filled into one of the (upper) ends. holder 5 and the end of the coupling half 3 facing one another are provided with annular radius grooves. Half coupling 3 at the end with a groove has a wedge notch II for gripping the balls, and the end of the stationary holder has a window 12 for ejecting the balls and directing them into the empty container 9 located below. The storage tanks are provided with covers 13, which simultaneously serve as handles for turning the arm 7.

The coupling works as follows. The bracket 7 is mounted and fixed with the aid of the handle 13 in a position in which the lower storage capacity 9 coincides with the window 12 of the fixed casing 5 (Fig. 2). The drive shaft 1 can be used as a mandrel for winding springs or it can be equipped with a measuring pulley, for example, in a device for merry cutting wires, etc. In the upper cumulative: a capacity is filled up with a certain number of balls 10 corresponding to the required number of revolutions of the driven shaft 2. The coupling is ready to work. The drive shaft begins to rotate. The pitch begins to rotate and the half coupling 3, fitted with a wedge cut 11. As soon as this cut is under the upper container with balls, a ball falls into it, which rolls along the annular radius tracks into the gap between the ends of the sleeve 5 and the coupling half 3 and moves the coupling half 3 to the closing with coupling half 4 on the driven shaft. The driven shaft begins to rotate, and the ball between the sleeve 5 and the coupling half 3 rolls toward window 12. For one revolution of the half coupling 3, roll the ball half of a circle. At this time, the cutout of 1 G captures the new ball, and the prediction,} th | Mb; p1 (it is called in the indented section, then gets into the window 12, and then into the empty container 9. The driven shaft makes as many revolutions as the balls were filled. the ejection of the half-coupling 3 into the lower capacity of the last ball opens with the coupling half 4 under the action of a spring-loaded pusher 6. The driven shaft 2 stops, after a certain number of revolutions.

To repeat the cycle, it is enough to rotate the bracket 7 with the help of the knobs 13, change into the container 9 empty and filled with balls. This switching on for the repetition of cycles can be easily carried out automatically with the necessary time delay, for example using the Maltese mechanism, the driving link of which can be communicated from a continuously rotating drive shaft.

Cam sleeve for transmitting rotation with

5 stops, containing two coupling halves with mutually interlocking face cams, one of which is spring-loaded, is installed with the possibility of axial movement and is connected with a fixed holder by means of

0 rolling bodies, characterized in that, in order to obtain a predetermined number of revolutions before stopping, a bracket is mounted on a stationary cage, on which storage tanks are fixed, filled with rolling bodies made in the form of balls, one by one that rotate during rotation into a wedge cut-out in the leading half coupling and moving along a radial annular groove provided on the facing one

to the other ends of the half coupling and the cage, before falling out of the window, made in the cage, and the number of revolutions per cycle is determined by the number of balls.
