Description

"I

The invention relates to instrumentation and can be used to smoothly convert rotational motion, mainly of medium and high torques. A transfer device for transforming and transforming and rotational movement is known, comprising a housing, a lead shaft housed therein and a drive shaft displaced axially in parallel thereto, a drive shaft mounted on them in radial bearings of the bottom of the disk, numbered on facing each other grooves, and intermediate elements in the form of balls, placed in grooves, and nap1) an automatic device for balls (see Czechoslovakia, ed. St. I76638j of class F 6 H 27/06, 1979).

A disadvantage of the known device is the incomplete connection of the transfer Kasiana in the meshing zone, friction in the transfer channel and unreliable rolling of the transforming common elements of the balls at the ends of the sections of the conversion grooves.

Fig. 1 shows a transfer device for converting and transforming a rotary twin | FIGS. 2 and 3 show double-arm cranks.

The transfer device Dp transformation and rotational movement transformation includes a housing, made of two parts 13 and lAp, a drive shaft 11 placed in it and parallel to it an axially displaced E displaced shaft 2p mounted on u {x. 26 two disks 23 and 24, having grooves 21,22 on facing each other and intermediate elements in the form of balls 9 ,, arranged in the grooves 21,22 and pointing the device for balls in the grooves 21,22, made in the form of a disk 30 s On its periphery, mounted on ovorotnoy pin 41 with the slots between dnska. In addition, the transfer device contains two two-arm cranks, one of the shoulders 39 and 40 of which are connected by means of a rotary axle 41, and the other axles 37 and 38 are housed in the bearings 27 of the drive P and the driven 12 shafts.

Both parts of the housing 13 and 14 are attached to each other and connected by locking elements (not shown 2278992

us). The disks 23 and 24 are attached to the dances 31 and 32. The leading shaft H with the disk 23 is mounted on a turntable in part 13 of the hull on two

§ bearings 25, the outer ring of which is placed in the bearing hole between the flange of the cover 17 and the spacer ring 35, its inner ring is in contact with to the shaft 1I in the radial direction, and the inner one is supported by its outer ring in the end direction in the spacer ring 35, and the inner ring is 1S in contact with the shaft II in the radial direction, and the outer ring of the bearing in the face direction rests on the spacer ring 35 and is located in the circumferential recess of the jig hole, and Cored oil-count: Tzom is in force contact with socket shaft shoulder 11.

In the axial hole of the lid 17, attached to the body part 13 with screws 20, there is an inner groove, inside which a sealing ring 33 is placed, preventing the penetration of contaminants into

30 the cavity of the transfer device and the leakage of grease to the outside The driven shaft 12, which is 1 1 parallel to the drive shaft 1 parallel, is displaced in the axial direction by the difference of running times, together with the disk 24 is placed in part 14 of the housing on two podgipnikah 26, the outer ring of which is placed between the collar of the lid 18 and the spacer ring 16 ,, serves to provide a radial load, and in -gut. The outer ring on the lipnik 26 is placed between the 1G1-reductive ring 36 and the flange of the shaft 12 and is intended to receive the radial and

5 axial forces. In the axial hole of the cover 7, screwed to the body part 13 of the screw-20, in the inner circumferential recess is placed the sealing ring 33, preventing

JQ penetration of contaminants into the internal cavity of the lubrication transfer device.

In the end plane of the disk 23 facing the common end cavity 55, there are formed six evenly spaced pericycloid transforming grooves 21, on the sides of which lancet platforms are made. Similarly, in the end plane of the disk 23 facing the common end cavity, nine uniformly placed hypocycloid transforming grooves 22 are formed with lance-shaped areas formed on the lateral sides.

The device is directed towards the chain (according to FIG.) Made in the form of a disk 30 with holes on its periphery in which balls 19 are placed. The shoulders of the cranks are connected to the groove and sleeve 10 by an end tooth, and are mounted in the axial direction (not shown) . Against the axial movement, the disk 30 is fixed with end beads placed on the surfaces of the arms 39 and BEFORE the crank.

In the second embodiment (FIG. 3), the crank is integral one-piece. Such an operation is advantageous in cases where the axial distance of the axes 0, 0 of the arms 37, 38 and the axial displacement P,, Pj of the axis Oj of the trunnion 41 are relatively small.

Transmitter operation: to transform and transform rotational motion.

The disc 23 rotated by the drive shaft 1I presses the grooves 21 to 22 of the HA balls 19. Thus, the generated pressure by the balls 19 is transferred to the slots 21 and 22 of the disk 24. The active axial component of this pressure is transmitted to the bearing 25 and the safety ring 36, the reactive axial component The center of this pressure is transmitted to the bearing 25 and the spacer ring 35 of the disk 23. The circumferential composition of this pressure causes the rotation of the disk 24 and the shaft 12. When both disks 23 and 24 rotate, the balls 19 rolling in their grooves 21 and 22 rotate on the crank. by n The direction of rotation of the discs 23 and 24. Balls 19, located at the extreme points of the grooves and outside the engagement floor, conversely move in engagement with the disc smoothly between the discs 23 and 24.

Placing the guiding device allows, in a certain range, to change the mutual relation between the axial displacements P,
