They are diametrically arranged on mutually perpendicular planes. The ends of the driving member (1) and a driven member (2) are shaped as cylindrical forks (3).There are spherical contact surfaces (4) at the inner side thereof. On them, there are formed a driving tooth (5) and a driven tooth (6). The rectangular-section teeth are arranged in the rectangular channels (7) of the spherical part (8). End stops (10) are fastened to each end of the spherical forks (3) by means of fixing bolts (9). The inner surfaces (11) of the end stops (10) touch the bottom of the rectangular channels (7). Antifriction plates (13) are placed between each contact surface (4) of the driving tooth (5) and a driven tooth (6) and the respective working plane (12) of the rectangular channels (7).

Description

Technical field

The utility model relates to a hinged clutch that is used in metalworking machines, rolling mills and other machines that require high torque transmission at relatively low rpm and low assembly space, as well as in combination hand tools.

BACKGROUND OF THE INVENTION

A universal variable axis clutch (1) is known, comprising a guide and a guide member, bent in the form of an ear and made of circular material. At the opposite end of the pins of the two units on the inside, cutouts are formed for ease of installation. The leading and driving members are connected to each other by a spherical rubber element. Rectangular grooves are formed on its surface, which are arranged on mutually perpendicular surfaces. Said construction is such that the centers of the two forks are displaced relative to each other and have a constant eccentricity.

The well-known variable-axis universal coupling is eccentric and therefore not suitable for rotary motion. However, if it is subjected to one, it will result in uneven loading with each revolution and vibration of the structure. In addition, its construction is unable to withstand heavy loads due to the presence of a rubber spherical element, and also the leading and guiding members are made of material with a circular cross-section, and thus the contact between them and the spherical element is made not on a plane, but on line that increases contact voltages. The forks of the forks, on the other hand, are of double material with circular cross section, which makes them unsuitable for installation in nodes with rotary motion without the use of additional connecting elements. In addition, the construction of the famous universal connector does not allow it to be installed in a small installation space.

The technical nature of the utility model

The object of the utility model is to provide a hinged clutch that allows the transmission of large torques without vibration, being convenient for installation in units with rotary motion and with little assembly space, and the contact voltages between its elements are minimized.

The hinge clutch consists of a guide member and a guide member, which are connected to each other by a spherical element. Rectangular grooves are formed around it, arranged diametrically on mutually perpendicular planes. According to a useful model, the ends of the guide member and the guide member are shaped like cylindrical forks. Spherical contact surfaces are made on their inside. A guide tooth is diametrically formed thereon and a tooth having a rectangular section is formed. These teeth are located in the rectangular grooves of the spherical element. End stops are secured to each end of the cylindrical forks by means of locking bolts. Their inner surfaces are in contact with the bottom of the rectangular grooves. Antifriction plates are placed between each contact surface of the guide tooth and the guide tooth and the corresponding working plane of the rectangular grooves.

The advantage of the swivel clutch is that it rotates evenly and without vibrations when rotating, as there is no eccentricity when connecting the link and the link. Another advantage is that the design allows for large torques to be transmitted at relatively small overall dimensions of the swivel clutch and is possible to be mounted in a small mounting space. The advantage is that direct assembly into machine units is possible without the use of intermediate units.

An example of a utility model

As can be seen from the accompanying drawings, the hinge connector includes a guide member 1 and a guide member 2 connected to each other by a spherical element 8. Rectangular grooves 7 are arranged on its circumference, which are diametrically arranged on mutually perpendicular planes. The ends of the guide member 1 and the guide member 2 are shaped like cylindrical forks 3. Spherical contact surfaces are formed on their inner side 4. They are formed respectively by a guide tooth 5 and a guide tooth 6. These teeth have a rectangular section and are located in the rectangular grooves 7 of the spherical element 8. End stops 10 are attached to each end of the cylindrical forks 3 by means of locking bolts 9. Their inner surfaces 11 are in contact with the bottom of the rectangular grooves 7. Between each contact surface 4 of the water shtiya tooth 5 and the driven tooth 6 and the respective working plane 12 of rectangular channels 7 are housed antifriction plates 13.

Using the utility model

The hinge connector is used as follows. Between the power drive of the machine and the respective end actuator (eg bending rolls or pull-shafts), a size-fitting swivel coupling is installed to ensure normal transmission of the required torque. Before mounting, a hinge (not shown in the figures) is placed on the hinge, which is pre-filled with grease. Given that the rotations of these end executive units are relatively low, other permanent lubrication is not necessary. The hinge clutch and its attachment to the other elements are installed by conventional means. The presence in the construction of the antifriction plates 13 guarantees its reliability in operation and its minimum wear. Because there are only two retaining bolts 9 in the structure, changing the antifriction plates 13 is quick and easy.
