Abstract

The utility model relates to an automotive tension wheel and idle wheel bearing which comprises an outer ring, an inner ring, rolling bodies, retainers and sealing rings, shoulder parts are arranged on the two sides of the outer ring, the section of the outer ring is T-shaped, the outer side part of the outer ring with the T-shaped section is equivalent to a bearing pedestal, and the inner side part of the outer ring is equivalent to an outer ring of an ordinary bearing. The automotive tension wheel and idle wheel bearing has the benefits that the outer ring of the bearing in the automotive tension wheel and idle wheel bearing and the bearing pedestal are designed into an integral structure, and in fact, the outer ring is a combined body of the outer ring of the ordinary bearing and the bearing pedestal; the automotive tension wheel and idle wheel bearing has the main advantages that a clearance is fixed, is stable and facilitates heat radiation, so that the service life is prolonged; the assembly is simplified, so that the overall quality is reduced, and the production cost is reduced.

Description

Automobile tension pulley and idle pulley bearing
Technical field
The utility model belongs to technical field of automobile parts, particularly relates to a kind of automobile tension pulley and idle pulley bearing.
Background technique
Automobile tension pulley bearing and idle pulley bearing are applied very extensive in automobile, tension wheel shaft bearing acts on synchronous belt slack list conventionally, be used for adjusting driving belt tension force, idle pulley bearing acts in synchronous belt pilled-in selvedge conventionally, for fixing, increase driving belt cornerite.Traditional automobile tension pulley bearing and idle pulley bearing are made up of bearing and the bearing support being arranged at outside bearing, and bearing adopts interference fit to be embedded in bearing support, as shown in Figure 1.This automobile tension pulley bearing being combined by bearing and bearing support and idle pulley bearing, because the effect of magnitude of interference can make the race deformation of bearing, raceway groove circularity is destroyed, the intrinsic play compression of bearing, while finally causing bearing to rotate, vibration becomes large, heating increases, and job insecurity and easily stuck, has affected working life.
Summary of the invention
The utility model is to solve the deficiency that above-mentioned prior art exists, and has proposed a kind of automobile tension pulley and idle pulley bearing, and its play no change is stable, has guaranteed working life.
The technological scheme that the utility model technical solution problem is taked is, a kind of automobile tension pulley and idle pulley bearing, comprise outer ring, inner ring, rolling element, retainer and seal ring, it is characterized in that, described both sides, outer ring are provided with shoulder, and its cross section is "T"-shaped.
The lateral part that described cross section is "T"-shaped outer ring is equivalent to bearing support, and inside portion is equivalent to the outer ring of plain bearing.
Outer ring and the bearing support of the bearing in automobile tension pulley bearing and idle pulley bearing are designed to integrative-structure by the utility model, is designed to cross section and is "T"-shaped outer ring.In described structure, outer ring is actually the combination of plain bearing outer ring and bearing support; Also be that in fact the utility model has changed the design that original automobile tension pulley bearing and idle pulley bearing are combined by bearing and bearing support, but directly this Combination Design become one structure.Owing to being integrative-structure, do not produce interference assembling, there is not any change in the original precision of bearing, and the life-span is ensured, assembles also simple; Meanwhile, owing to being integrative-structure, the lateral part that is equivalent to bearing support can be designed thinlyyer, it is large that space becomes, and makes the diameter of rolling element can be larger, thereby make dynamic load rating and the static load of tension wheel shaft bearing and idle pulley bearing larger, also be more conducive to heat radiation, increased working life; And total quality can alleviate 35% left and right, reduce cost of production.
Major advantage of the present utility model is: play no change, and stable, be conducive to heat radiation, increase working life; Simplify assembling, total quality alleviates, and has reduced cost of production.
Brief description of the drawings
Fig. 1 is product structure schematic diagram in prior art.
Fig. 2 is a kind of embodiment structural representation of the utility model.
In figure: 1-outer ring, 2-inner ring, 3-steel ball, 4-retainer, 5-seal ring, 6-bearing support, 7-shoulder.
Embodiment
As shown in Figure 2, it comprises outer ring 1, inner ring 2, steel ball 3, retainer 4 and seal ring 5, does not establish bearing support, and 1 both sides, outer ring are provided with shoulder 7, and its cross section is "T"-shaped.The lateral part of outer ring is equivalent to bearing support, and the inside portion of outer ring is equivalent to the outer ring of plain bearing.

Claims (2)

1. automobile tension pulley and an idle pulley bearing, comprise outer ring, inner ring, rolling element, retainer and seal ring, it is characterized in that, described both sides, outer ring are provided with shoulder, and its cross section is "T"-shaped.
