Abstract
The utility model provides a tensioning wheel comprising a mandrel and a bearing, wherein the bearing comprises an inner bearing ring, an outer bearing ring and a ball arranged between the outer surface of the inner bearing ring and the inner surface of the outer bearing ring; the mandrel is arranged in the inner bearing ring and fixedly connected with the inner bearing ring; the end surface of the mandrel is provided with a regulating groove; and one end surface of the mandrel is provided with a locating pin, and the other end surface of the mandrel is provided with a locking mechanism for fixing the mandrel. The tensioning wheel has the beneficial effects of capability of realizing a belt tensioning function through the coordination of the mandrel and the bearing, simple structure and low cost.
Description
Technical field
The utility model relates to tension device, relates in particular to Idle wheel.
Background technique
At present, the volume of the motor of automobile constantly dwindles, and this causes the tensioning space of Idle wheel constantly to be compressed; In order to accomplish tension in limited space, the structure of Idle wheel becomes increasingly complex; Cause cost to increase.
The model utility content
In order to solve the problems of the prior art, the utility model provides a kind of Idle wheel.
The utility model provides a kind of Idle wheel; Comprise mandrel, bearing; Said bearing comprises bearing inner race, bearing outer ring and the ball between said bearing inner race outer surface and said bearing outer ring internal surface, and said mandrel is positioned at said bearing inner race and said mandrel and said bearing inner race and is fixedly linked; Said mandrel end face has regulating tank, and said mandrel one end face is provided with locating stud, and said mandrel other end is provided with the locking mechanism of fixing said mandrel.
As the further improvement of the utility model, said regulating tank is curved.
As the further improvement of the utility model, this Idle wheel also comprises dust cover, and said dust cover is installed between said mandrel outer surface and the said bearing outer ring internal surface.
As the further improvement of the utility model, the gap is between 0.2 millimeter to 0.3 millimeter between said dust cover and the said bearing outer ring internal surface.
As the further improvement of the utility model, said locking mechanism is screw hole and the bolt that matches with said screw hole.
The beneficial effect of the utility model is: this Idle wheel is through having realized mandrel and cooperating of bearing the effect of tightening belt, and simple in structure, cost is low.

Fig. 1 is the stereogram of the utility model.
Fig. 2 is the plan view of the utility model.
Fig. 3 is the rear view of the utility model.
Fig. 4 is the sectional view of the utility model.
Embodiment
Extremely shown in Figure 4 like Fig. 1; The utility model discloses a kind of Idle wheel; Comprise mandrel 2, bearing; Said bearing comprises bearing inner race 6, bearing outer ring 5 and the ball between said bearing inner race 6 outer surfaces and said bearing outer ring 5 internal surfaces, and said mandrel 2 is positioned at said bearing inner race 6 and said mandrel 2 is fixedly linked with said bearing inner race 6; Said mandrel 2 end faces have regulating tank 4, and said mandrel 2 one end faces are provided with locating stud 1, and said mandrel 2 other ends are provided with the locking mechanism of fixing said mandrel 2.
Said regulating tank 4 is curved.
Because the engine stretching wheel bearing very easily receives muddy water and invades, cause Idle wheel to damage, so this Idle wheel also comprises dust cover 7, said dust cover 7 is installed between said mandrel 2 outer surfaces and said bearing outer ring 5 internal surfaces.
The gap is between 0.2 millimeter to 0.3 millimeter between said dust cover 7 and said bearing outer ring 5 internal surfaces.
Said locking mechanism is screw hole 3 and the bolt that matches with said screw hole 3.
This bearing outer ring 5 is as the belt wheel surface of Idle wheel, and bearing outer ring 5 contacts with belt.In order to regulate the degree of tightness of belt; The Idle wheel degree of tightness of must the mobile position regulating belt so; This Idle wheel moves through regulating tank 4 just, and positioning rod or latch insert in the regulating tank 4, and this Idle wheel is that displacement is carried out at the center with positioning rod or latch; Because regulating tank 4 is curved, so the displacement of this Idle wheel just can change the degree of tightness of belt; After Idle wheel moves into place, through locking mechanism Idle wheel is fixed, for example the cooperation through screw hole 3 and bolt is fixed on a certain position with Idle wheel.
This Idle wheel simple in structure, cost is low, installation and easy to adjust, and has the dust and water protection performance, has promoted the quality of Idle wheel.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
