Abstract
The utility model discloses an idler wheel type slewing bearing. The idler wheel type slewing bearing comprises a rail, an idler wheel and a rotating disc. The rail is an inclined-plane rail, the idler wheel is an inclined-plane idler wheel matched with the inclined-plane rail, and the rail and the idler wheel are of inclined planes. During rolling, rolling friction is generated between the idler wheel and the rail, and abrasion between the idler wheel and the rail is small. The idler wheel type slewing bearing is simple in structure, durable in use, and suitable for popularization.
Description
Technical field
The utility model relates to a kind of roller type pivoting support, belongs to field of bearings.
Background technique
Often adopt roller type pivoting support structure on all kinds of turning round equipment, roller adopts single-wheel or with two roller structures of equalizer bar.Existing roller type pivoting support often adopts flat tread wheel and planar tracks, its shortcoming is: the roller that turns round under a certain angle of circumference speed, and due to the wide existence of wheel, wheel is inboard exists speed difference with the outside, roller produces sliding friction, and roller and the track rate of wear are very fast.
The model utility content
The utility model is intended to provide the roller type pivoting support that can reduce roller and track wearing and tearing.
The purpose of this utility model can reach by following measures: a kind of roller type pivoting support, comprise track, roller and rotating disk, and described track is the inclined-plane track, roller is the inclined-plane roller that matches.
The technique scheme difference with the prior art is: described track and roller are the inclined-plane, and during rolling, roller inboard and the outside speed difference can not occur, and roller and track produce rolling friction, and the wearing and tearing of roller and track are little.
The utility model is simple in structure, and is durable in use, is suitable for promoting.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the utility model roller type pivoting support embodiment's structural representation.
Embodiment
With reference to Fig. 1, a kind of roller type pivoting support comprises track 3, roller 2 and rotating disk 1, and roller 2 is connected with rotating disk 1 and can rolls on track 3, and this track 3 is the inclined-plane track, and roller 2 is the inclined-plane roller that mates with inclined-plane track 3.
In roller when motion,, because the rolling surface of roller 2 is the inclined-plane, roller 2 is inboard speed difference can not occur with roller 2, and roller 2 produces rolling friction with inclined-plane track 3, and the wearing and tearing of roller 2 and track 3 are little, long service life.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (1)
1. a roller type pivoting support, comprise track, roller and rotating disk, it is characterized in that: described track is the inclined-plane track, and roller is the inclined-plane roller that matches.
