Description

Belt separators for rectilinear rolling bearings are known, which consist of separate links that are articulated and made in the form of an endless chain with rolling bodies located between the links.

In the proposed belt separator, in order to increase the wear resistance of the separator elements and the performance of the support, as well as to ensure the best direction of the rolling bodies when moving along the bearing surfaces, the separator link is interconnected by trunnions placed in the holes of the conjugate link, while the trunnions and holes are located on the four protrusions of the links of the links, two on each side, and the links are kept from being separated by the rolling bodies inserted into the sockets formed by the jumpers and their lateral projections.

In order to keep the rolling bodies in the sockets, the curvature of the rolling bodies surrounding the rolling bodies of the guide surfaces of the jumpers of the links is made close to the curvature of the rolling bodies.

FIG. 1 shows a diagram of four separator links, of which one link is shown at the moment of separation; in fig. 2 is a diagram of three connecting links, of which the latter is placed at almost the right angle to the previous one for embedding the rollers; in fig. 3 shows diagrams of separator links for cylindrical rollers or needles and barrel-shaped rollers and balls; in fig. 4 is a diagram of a complete prismatic support, in which the first part is presented in section.

The link / is connected to three assembled links 2, for which the pin 3 is hingedly inserted into the hole 4 of the tongue of the 5 link. Each link has the same size and shape. When connected, the links must lie on a straight line.

Only after coupling of each next link is inserted the needles 6 or rollers, for which the last link is placed at almost a right angle to the previous one and with a slight pressure the needle 6 or the roller is pressed between the thickenings 7 or between the guide surfaces 8 of the bridges 9.

The nested needles 6 or rollers, at the slightest waste, prevent the links from uncoupling, and they turn out to be connected in one piece.

The guide surfaces 8 can be fitted to any shape of the rolling elements.:

In separators from individual links, the radius of curvature is very small, due to which it is possible to make infinite supports of small height. The rolling surfaces of the supports consist of two parts 10. At the ends of the supports, the separator enters the unloaded area and can support the main part for the entire length of the stroke.

Subject invention

1. A belt separator for rectilinear rolling bearings consisting of separate links that are hinged together and made in the form of an endless chain with rolling bodies between the links, characterized in that, in order to increase the wear resistance of the separator elements and the performance of the support, as well as providing a better direction of the rolling bodies when moving along the supporting surfaces, the separator link is connected between the trunnions placed in the holes of the conjugate link, while the trunnions and the holes are located at four degrees ah jumper links, two on each side, and the units are retained by releasable rolling bodies, vstavlennymi- in the nest formed by the webs and lateral projections.

2. Tape separator on. 1, characterized in that, with the holding body of the rolling bodies in the sockets, the curvature of the surrounding rolling bodies of the guide surfaces of the jumpers of the links is made close to the curvature of the rolling bodies.
