SU585332A1 - Torque transmitting coupling - Google Patents

Description

one

The invention relates to mechanical engineering and can be used in sleeves for transmitting torque during synchronous rotation of the driving and driven members by mixing the effects of backlashes, inaccuracies and preparations and mounting the floor of the couplings.

A known clutch for the transmission of torque, containing a drive and a driven half-coupling, interconnected by mating protrusions and depressions lj.

However, this coupling does not eliminate the effect of manufacturing inaccuracies (within accepted tolerances) and installation, which adversely affect the synchronism of rotation and unaccented operation.

The aim of the invention is to reduce the influence of manufacturing and installation inaccuracies on the technical characteristics and increase synchrony and smoothness, operation,

This is achieved by the fact that the interacting surfaces of the coupling halves are made with pockets connected by hydraulic resistances with an external source of pressure of the working medium,

At the same time, the pockets made on the load-1X and unloaded at one and the same direction of rotation of the interacting surfaces of the coupling halves, respectively, connect each other and: the source of the pressure of the medium by the general hydraulic resistance.

Fig, 1 shows the described coupling, a longitudinal section; in fig. 2 shows a cross-section A-A in FIG. one.

Claims (2)

In the respective supports (not shown), shafts 1 and 2 are installed. On shaft 1, an external splined coupling half 3 is fixed, on a veleu 2 — internal half coupling 4. Hydrostatic pockets 5 are made on the working surfaces of coupling half 4, the working medium is supplied from an external source to pressure throttle m 6 and 7, through the throttle 6 and the annular groove 8 feed the pockets, transmitting the torque when rotating counterclockwise (see Fig. 2), and through the choke 7 and the groove 9 - pockets, transmitting the torque clockwise . When rotated counterclockwise, for example, shaft 2, by changing the gaps in the sealing pockets, pockets can be made so that the gaps will not change under the route, i.e., the rigidity within certain limits will be absolute if the resistance changes as the load changes. chokes 6 and 7 will automatically change as a function of pressure in the pockets) the pressure in the channel 8 and the corresponding pockets increases, and in the canape 9 and the corresponding pockets it decreases, and torque is transmitted to the shaft 1 through the hydrostatic cushions From the direct contact of coupling half 3 and 4. With the inevitable inaccuracy of manufacture (misalignment and misalignment of shafts 1 and 2 and coupling half 3 and 4), however, within the limits excluding direct contact between coupling 3 and 4 between them, the pressure p in the pockets of one direction will be the same, since They are fed from one throttle, and almost constant, since the working surfaces of the coupling halves are symmetrical. Therefore, the driven coupling half 3 will have only pure torque, and this shaft will rotate evenly. Obviously, if you carry out hydrostatic pockets also on the centering surfaces of the slit joint and feed them through the appropriate special hydraulic connectors, then the transverse force will descend onto the driven shaft, and this joint will transform into the centering spline connection having hydrostatic contact surfaces. Such a connection can work as a non-hazardous one and provides chioto liquid friction between the slit-on and the splined bushing during their mutual movement. Thus, the proposed connection practically provides for elimination of backlashes and compensation for inaccuracies in the mounting of coupling halves, increasing the accuracy, smoothness and synchronism of rotation, reducing shock and edge pressure, i.e. increased load capacity, and the possibility of using in the manufacture of non-deficient materials.
