Abstract

A device is disclosed for supporting a first member which is rotatable about a mainly vertical axis on a second member. The device is primarily intended to be used for supporting very large members, which carry very heavy loads. The device incorporates two races and a plurality of rollers cooperating therewith. In order to avoid sliding movements in the contact between the rollers and the races at varying loads and for achieving an even load distribution on all rollers, the rollers are resiliently suspended in support members which are adjusted such that the rollers will engage their associated race under preload. The rollers and/or the races may be cambered or the support members may be displaceable in the longitudinal direction of the rollers and contact the adjacent elements via arcuate supporting surfaces for achieving a pure rolling movement in the contact between the rollers and the races due to race movements.

Description

one

The invention relates to mechanical engineering, in particular to a roller coin, mainly for rotating elements with vertical clues.

The purpose of the invention is uniform load distribution by independent adjustment and self-installation of yor elements.

Figure 1 shows the direction, general view} in FIG. 2, enlarged parts of the supporting elements; on fig.Z - roller with samoustanaayuyuschimi- with supporting elements; 4 is a spring support element.

Roller guide, predominantly for a rotating element with a vertical axis, containing movable elements relative to each other, one 1 of which is made with a conical guide surface 2 and a working flat surface 3, and the other 4 - from rolling surfaces in the form of mounted on the base 5 on the supporting elements of the rollers 6, which are installed with the possibility of contact with the said conical guide surface and the flat working surface, as well as a means for adjusting the tension, associated with onopiibiMH e the elements of the rollers 6, made in the form of bearings -. Rolling coils .7, placed on an axis on both sides of roller 6, and the tension wedge for rollers in contact with the working flat surface is made in the form of an elastic element 8, and for rollers in contact with a conical guide surface, in the form of a preloaded spring 9 and the supporting elements and the base are installed to the men, while the working surfaces of the rollers 6 are made spherical; the rollers with the supporting elements are mounted movably in the axial direction, and the tension adjustment means is made with arcuate installation surfaces 10 and mounted on the support elements and the base 11 by means of the installation fingers 12; The preloaded spring 9 is provided with an element for adjusting its position - a nut 13.

The element for adjusting the position of the spring. Is made in a view of the hydraulic cylinder with a piston 14.

When the load is applied at an angle of the code, the group of rollers remains in contact with the corresponding surface due to the installation of each roller on the supporting elements. In this case, the rollers do not overload due to the fact that their supporting elements are made resilient, and the change in the position of one element relative to another is insignificant, since the springs are preloaded. The roller 6 is radially movable in the frame structure 15, in which it is guided by guides. The roller also has the possibility of axial movement relative to the base, since the frame, the structure is placed on the base-1 with the possibility of movement, the adjusting elements have arcuate-shaped mounting surfaces 10 interacting with the base 11 and with the surface of the supporting elements. Due to this, the adjustment elements can tilt, with the result that the rollers will roll over the respective surfaces without slipping. The adjustment elements are guided and held by the adjusting fingers 12. These fingers enter into the corresponding grooves at the ends of the support surfaces. The distance between the bearing surfaces of the adjustment element to a certain extent depends on the load perceived by the adjustment elements.

Under normal load, the arcs that define the two surfaces of the adjusting elements preferably have a common center. Since the length of the adjusting elements varies very slightly with varying loads and their deflection angle is relatively small, the change to the axial movement of the roller can be ignored.

Changes in the position of the treadmill relative to the base may

be valid due to the mobility of the roller. Another adjusting element in the form of a preloaded spring 9 contains a packet of belleville springs 16, which is clamped between

BOTTOM 17 AND THE SUPPORT RING 18. By turning the nut 13 you can compress the package to the required pre-load. The bearing element in the form of a bearing rests on a cylindrical

surface of the outer face surface of the adjusting element. The position of this cylindrical surface is fixed, while the load does not exceed the value of the preload of the spring package. If this force is transferred to the bearing, then an adjustment element can be provided with a hydraulic displacement device made in the form of an annular piston 14 acting on the nut 13. As the pressure in the medium increases, the support ring 19 moves to create a preload of the spring package. The adjustment element can be

installed without a gap between the bearing and the base, as a result of which the pressure in the medium will decrease, and the spring force will act on the bearing, freeing the nut 13,

Other installation options for adjusting elements are possible. Oim can be rigid and interact with the base, which can be made elastic. The surfaces of the rollers are made with spherical working surfaces that allow the rollers to self-align without slipping, if the running are expensive: and are displaced due to the elasticity of the adjusting elements. In this case, the adjusting elements may not have arcuate mounting surfaces and should be rigidly fixed relative to bearing and base. Due to this embodiment of the roller guide, the load is evenly distributed between the rollers.
