Abstract

The invention relates to the field of mechanical engineering and can be used in various devices for detachable connection of parts. The goal is to increase the transmitted torque. The joint consists of shaft 1, female parts 2, split ring 3 and pins 4 and 5. Female body 2 is made with two open longitudinal grooves in which the ends of the main pin 4 are placed. In the same grooves the protrusions of the split ring 3 are arranged, made in place of the half-ring semi-ring elements of the split ring 3 and forming with their end surfaces radial grooves interacting with the side surfaces of the protruding ends of the pin 4. The split ring 3 is made not with two diametrically opposed openings in which the ends of the additional pin 5 are located, and with longitudinal threaded holes 10 in which the ends of the screws 11 are mounted for axially fixing the female part 2 on the shaft 1. The design allows to increase the transmitted torque for counting the possibility of transmitting rotation from shaft 1 to the female part 2 by means of two pins 4 and 5. 4 sludge. and S (L S

Description

The invention relates to mechanical engineering and can be used in various devices for the detachable connection of parts,

The purpose of the invention is to increase the load capacity,

Figure 1 shows the connection section; in fig. - view A in FIG. one; on fig.Z - section BB in figure 1; figure 4 - section bb In figure 1.

The joint consists of the shaft 1, the enclosing part 2, the split ring ™ 3 and the pins 4 and 5. The shaft 1 is made with two transverse holes for mutually perpendicular pins 4 and 5 located in parallel planes of the body. made with two open longitudinal grooves 6, in which the ends of the first pin 4 are placed. In these same grooves there are protrusions 7 of the detachable ring 3, made in the place of the thickening of the semicircular elements of the split ring and forming radial grooves 8, which interact with base surfaces of the protruding ends of the pin 4. The split ring 3 is made with two diametrically opposed openings 9i in which the protruding ends of the additional pin 5 are located, and with longitudinal threaded holes 10 in which the ends of the screw 11 are installed for axial fixation of the ox fitting piece 2 on the shaft 1 o

The assembly of the compound is made after

In the hole of the shaft 1 is pressed with pins: 4 and 5 so that their ends protrude from it to the same size equal to the thickness of the wall of the hub covering parts. After that, a detachable ring 3 is mounted on the shaft 1 so that its transverse holes 9 cover the ends of the additional pin 5, and the radius surfaces 8 of the protrusions 7 cover the ends of the pin 4. Then the female part 2 is installed on the shaft end so that its grooves 6 cover the ends of the first pin 4 and the protrusions 7 of the split ring 3 "After that, screws 11 are installed in the longitudinal holes of the female part 2 and the split ring 3, which, when screwed into the threaded holes 10 of the split ring 3, tighten the The etal 2 is attached to the pin 4, since the split ring 3 does not have a longitudinal movement due to the presence of the second pin and because of its extension 7 abut against the ends of the pin 4.

Disassembling the connection is straightforward and is carried out as follows. The screws 11 are twisted from the holes 10 of the split ring 3 and the female part 2 is removed from the shaft 1, freeing the projections 7 of the ring 3 "Parts of the ring 3 are then easily removed.

The proposed plug-in design allows an increased steepness of the moment to be transmitted due to the fact that the female part is fastened to the shaft with two pins and a split ring, the All-powerful shaft and its protrusions with the ends of the first pin and the longitudinal grooves of the cov- eral parts, and the transverse holes and the holes with the ends of the second pin, with both the pin attached to the shaft in two mutually perpendicular planes.

Claims (1)

Claims. A detachable joint containing a shaft, a female part not mounted thereon, means for its circumferential fixation, executed in the form of diametrically oppositely located on the end surface of the female part — open part of the grooves in which the ends of the pin installed in the diametrical hole of the shaft are located, as well as means for axial fixation of the female parts made in the form of mounted on the shaft and rigidly connected in the axial direction with the latter by means of threaded elements of the ring with axial profiled The grooves covering the ends of the pin on the side opposite to the grooves of the female part, are different in that in order to improve the load capacity, it is provided with an additional pin installed in the diametrical hole of the shaft in a plane parallel to the plane of the main pin and perpendicular to the last, the ring is located coaxially to the gapping part and is made detachable in the form of two half-ring elements connected to the shaft in the circumferential and axial directions by means of flax pin on the end surfaces of the semi-ring elements from the main The pin is made adjacent axially directed protrusions, and the above shaped recesses are formed by the end surfaces of the corresponding protrusions of the semirings. fag. five Compiled by E.Ivanov.
