Description

(5) COLLAR

J

The invention relates to mechanical engineering, namely a yoke, and can be used in the assembly and disassembly of compressors and internal combustion engines, in particular rotors with spring-loaded sealing elements.

The known collar, containing an elastic element in the form of a tape., At one end of which, on the outer surface, grooves are made, and a spring connected rigidly with the other end. an elastic element and interacting with the grooves 11.

A disadvantage of the known construction is that it has limited technological capabilities.

The closest in technical essence to the present invention is a yoke containing an unequal square with a longitudinal window in an elongated shelf, an elastic band with a stop and placed in a short shelf of the elbow

clamping screw with nut for crimping the part 2.

However, this clamp does not provide an expansion of technological capabilities.

The purpose of the invention is the expansion of technological capabilities.

This goal is achieved by the fact that an additional elastic band is rigidly attached to the elongated shelf, and a transverse slit under the pressure screw is made on the short shelf, and the length of the elastic band is made at least two part perimeters.

FIG. 1 shows the clamp, about 15 cut; in fig. 2 - installation of the clamp on the rotor of the trochoid compressor in the process of disassembling it; in fig. 3 shows section A-A in FIG. 2; in fig. k is node G in FIG. 3

. The proposed design of the clamp contains an unequal angle 1 with an elongated and C-shaped shelves, the elastic tape is rigidly connected to the square — the main 2 and additional 3, rigidly connected to the tape 2, the stop 4, and the pressure screw 5 with a finger 6, in which it is perpendicular to its The axis has a threaded hole for the screw shaft 5. In the elongated shelf of the square 1, a longitudinal window 7 is made, the width is equal to or slightly larger than the width of the tape 2. The C-shaped shelf is made with a uniformly thinned, spring-acting end and transversely PS) with a cutout 8, located perpendicular to the shelf, the depth of which is more than half the height of the shelf and a width equal to or slightly larger than the diameter of the push rod screw 5. By means of a slot 8 in the C-oa different shelf and its thin end, the pressure is removed quickly screw 5 together with finger 6. Elastic tape 2 has a length of not less than two perimeters along which the parts to be crimped are located. The stop A is made in the form of an angle with a tapered angle in the shelf at the end of the pressure screw 5 and is fastened on the belt 2 at a distance from the edge of the square 1 equal to the perimeter, in which the crimped de / ali are located. Additional elastic tape has a length of not less than the perimeter, crimped parts are arranged according to KOTopoViy. The work of the collar during assembly and disassembly of parts with parts freely installed relative to each other and having their fixation elements in 1L) basic or basic parts, in particular, trochoidal compressors, is carried out in the following sequence. When disassembling, all the nuts clamping the end cover 9 to the compressor housing 1 are pre-swaged from the studs, and the end cover 9 moves along the studs so that the angle bracket 1 can be laid into the resulting gap, but at the same time this gap should not significantly exceed the width of the square 1. From the C-shaped shelf of the square 1, pull out the pressure screw 5 with the finger biv forming the slot for the hairpins of the plant and the belt 2 together with the fixed stop with it, so that it completely covers all spring-loaded sealing elements 11, located at the tops of the rotor 12. 9 54 Then the end of the spring 2 is driven into the longitudinal window 7 of the square 1 and pulled until the stop k does not pass through the window 7 and becomes pro-TIB C-shaped shelf of the square 1, This tape 2 almost tightly covers all sealing elements 11. For the final tightening of the spring-loaded sealing elements 11 in order to prevent them from falling out from the tops of the rotor 12 and subsequent damage to them, finger 6 is inserted into the C-shaped shelf of the elbow 1 together with the pressure screw 5 so that its end went into deepening emphasis. Thereafter, by rotating the pressure screw 5, the spring-loaded sealing elements 11 are fully tightened and the rotor is removed from the compressor housing 10. The pp assembly end cap 9 with the rotor 12 installed is mounted horizontally, for example. on the workbench, so that the rotor 12 is located on top. Springs, intermediate and sealing elements-rollers 11 are installed in slots of the rotor 12. The clamp is screwed into the ring - for this, pull out the screw 5 with the finger 6 from the C-shaped shelf of the square 1; The plant ends the elastic tape 2 into the window 7 of the square 1 and pulls it so that the stop 4 almost fits to the window 7 of the square 1. Then the clamp is mounted on the rotor 12 so that it covers the sealing elements 11, draw the final elastic tape 2 until the stop k completely enters the window 7 of the square; in the C-shaped shelf of the square 1, plant a finger with a stop screw 5 and, by rotating the screw 5, tighten the clamp until the sealing elements 11 are fully inserted in the slots of the rotor 12. After that, the end cover 9 together with the clamped rotor 1.2 is mounted on the body studs 10, it should be ensured that the vertices of the rotor 11 go into the recesses of the working cavity 13 and slide toward them so that it does not reach the mating surface of the housing 10 by a distance equal to or slightly larger than the width of the square 1. Then, the clamp is loosened by slightly turning out the pressure screw 5, which is then pulled out of the C-shaped shelf of the square 1 together with the finger 6. Then the clamp is removed by pulling the tape 2 together with the stop k through the window 7 of the square 1 After removing the clamp Finally, the end cap 9 is slid over the studs of the housing 10 and secured with nuts. The technical and economic effect of using the clamp can be achieved by expanding the technological capabilities of the clamp. Claims containing a non-parallel square with a longitudinal window in the Rig. Shelf of the shelf, an elastic band with an emphasis and placed in the short shelf of the square with a compression screw with a nut that, in order to expand technological capabilities, an additional elastic band is rigidly attached to the elongated shelf, and a transverse slit under the pressure screw is made on the short shelf, and the length of the elastic ribbon is made at least two of the perimeters of the part.
