Description

The invention relates to mechanical engineering, in particular to the use of steel ropes as elastic elements in the supports of motion transducers and vibration isolators.

The purpose of the invention is to ensure the maintainability of the assembly by using a liner with a chamfer facilitating directional penetration of the metal during pressing, and dividing the metal of the insert during pressing into two easily removable parts formed by the inner surface of the sleeve.

FIG. 1 shows the end of the rope with a liner and sleeve; in fig. 2, the process of pressing the liner and sleeve onto the end of the rope in FIG. 3 - device assembly; in fig. A - insert1, section; Fig / 5 - sleeve, cut.

The device for fixing the end of the rope 1 consists of a support 2 with a hole 3 in which the cup 4 is pressed with an annular groove 5 under the retaining ring 6.

The end of the rope is placed in the liner 7, the inner surface of which has a bevel 8, cylindrical. Section 9, and two conical sections 10 and 11, extending in opposite sides.

At least three longitudinal cuts 12 are made in the two conical sections. The sleeve 13 is made with two conical sections 14 and 15 extending to the ends of the sleeve. The insert 7 and the sleeve 13 are pressed onto the end of the rope and the whole assembly is installed in the glass 4 of the support 2 and secured with a retaining ring 6.

The assembly of the device for fastening the elastic elements (ropes) in the supports of the converter is carried out as follows.

At the end of the elastic element 2, for example, the rope 1, which is first inserted into the calibrated hole in the plate 2, the insert 7 is put on, after which the sleeve 13 is put on and the stop 16 and the plug 17 are placed under the press.

When the punch 17 moves, the sleeve 13 deforms the insert 7, while the material insert 7 flows and fills the free space of the internal cavity 13 and penetrates into the space between the strands and wires of the rope 1. As a result, the sleeve is securely fastened to the rope. For convenience of execution

the operation of the internal cavity of the metal sleeve 13 is made conical. The angle of inclination of the outer surface of the insert 7 is somewhat greater than the angle of inclination of the generatrix of the lower

cone of the inner surface of the sleeve 13. This prevents the liner from being squeezed and facilitates the penetration of its metal into the interconnect and interwire space.

The presence of chamfer on the inner surface of the insert makes it easier to put it on the end of the rope. And also contributes to the directional penetration of the metal during pressing.

To increase the reliability of fixing the sleeve on the rope 1 and, further, the possibility of reuse of the sleeve, its inner surface is made in the form of two

truncated cones connected by smaller bases.

When pressing the sleeve 13 metal t

The insert 7 is positioned to form the juice of the jB at its upper end and its bottom1

cone. In addition, part of the metal is in the interconnect and interwire space;

At the bottom of the calibration hole 2 there is a recess 18 located around the circumference of the circle.

large diameter. The depth of the calibrated hole in the plate 2 together with the recess 18 is 1.5 mm less than the height of the sleeve 13. This contributes

rounding in the lower part of the liner 7 with the sleeve 13 and, further, fastening the rope in the support of the motion converter or vibration isolator.

Metal removal force

the cable sleeves are equal to the force of the material breaking the insert.

Next, the elastic element (rope) 1 with a fixed end

a metal sleeve 13 is inserted into the cup 4, previously pressed into the hole 3 in the support 2 of the transducer of movements or the vibration insulator, and fixed with a stop

ring 6, which is inserted into the groove 5 of the cup 4 and supported by the bent part of the metal sleeve 13.
