Embodiment Construction

[0010] Depend on figure 1 From the schematic diagram shown, it can be known that the composite roller of the present invention is composed of an outer bearing assembly and an inner slider assembly.

[0011] The outer bearing assembly is composed of an outer ring 1, an inner ring 3, a roller 2, a retaining ring 5 and a spacer 4. There are two inner rings 3 in total, and a spacer 4 is installed between the two inner rings 3. There is a raceway evenly opened on the surface of the ring 3, the rollers 2 are installed in the raceway, the two rows of rollers 2 are inclined in opposite directions, and the direction of inclination is that the rollers 2 gradually penetrate into the inner ring 3 from the outside to the inside, and the outer ring 1 is directly set on the two rows of rollers 2, and there is a retaining ring 5 connected between the outer ring 1 and the inner ring 3. There are two retaining rings 5, which are respectively located on both sides of the two rows of rollers 2. ...

Abstract

The invention relates to a composite roller wheel with full complement tapered rollers, which comprises an outer bearing component and an inner sliding block component, wherein the outer bearing component consists of an outer ring, inner rings and rollers, the inner sliding block component comprises a side roller wheel bracket, sliding block screws and a metallic gasket, the side roller wheel bracket is sleeved with the outer bearing component and is in a stair shape, one end of an inside wall of the outer bearing component pushes against the side roller wheel bracket, the other end of the inside wall of the outer bearing component is fixed by an outer cover in a limiting manner, and the outer cover is fixed on the side roller wheel bracket by screws. With the adoption of the device, a double-row tapered roller bearing can bear a certain axial force, the axial loading capacity of the composite roller wheel can be improved, besides, the outer bearing component can move horizontally, and the inner sliding block component can move vertically, so that the effect of rotation in two directions is achieved.

Description

technical field [0001] The invention relates to a compound roller with full complement of tapered rollers. Background technique [0002] At present, for equipment that needs to use rollers that rotate in two directions, such as bearings for forklift masts, etc., ordinary bearings are used in existing equipment to operate, and ordinary bearings can only bear diameters Directional force, but cannot withstand axial force, and can only move in one direction, so ordinary bearings cannot meet the needs of the work. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a roller that can rotate in two directions and can carry loads. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a composite roller, the innovation point of which is to include an outer bearing assembly and an inner slider assembly; [0005] The outer bearing assembly is composed o...
