Description
Technical field
The utility model relates to motor air-conditioning train design field, more particularly to a kind of wear-resistant high-intensitive motor are empty
Adjust train tensioning wheel.
Background technique
Motor air-conditioning train tensioning wheel in high-intensitive use process, due to supporting plate rotation ontology it is motionless so between shape
At very big friction, plastic washer is often set between supporting plate and wheel body, although can play for supporting plate in existing situation
Certain protective effect, but since body outer wall is relatively thin, so the contact area very little between ontology and plastic washer, steel
Ontology often breaks washer, to directly contact friction with supporting plate, causes the service life of entire tensioning wheel very short, and calorific value is big,
The problems such as noise is big.
Utility model content
The utility model devises a kind of wear-resistant high-intensitive motor air-conditioning train tensioning to solve the above technical problem
Wheel, including supporting plate, supporting element, ontology and setting clockwork spring in the body, the supporting element setting the supporting plate with it is described

As a result, since the clockwork spring is the steel bar for rolling tightly sheet, once friction will be generated by contacting with the fagging, opening
Not only abrasion can have been generated in the bearing up pulley course of work but also will cause very big noise, and the effect of the block body is to prevent the clockwork spring direct
It is contacted with the fagging, to reduce rigidity friction and noise.
As the preferred of the utility model, the axle sleeve and the fagging carry out plastic connection.
The axle sleeve wraps up the fagging as a result, and the difference in areas of the axle sleeve is more than or equal to the supporting plate and waits connecting
The area in face reduces the pressure that the axle sleeve is subject to so that the contact area of the supporting plate and the axle sleeve is maximum, reduces
Axle sleeve attrition.
As the preferred of the utility model, the axle sleeve is preferably plastics.
The abrasion for reducing described and the ontology can either be played as a result, and rigidity friction is become to the friction of plastics and steel
Also the noise that tensioning wheel generates during operation can be reduced, additionally it is possible to reduce the generation of frictional heat.
As the preferred of the utility model, the supporting plate, the supporting element, the clockwork spring and the ontology pass through center
Shaft connection positioning.
The supporting plate and the body central are provided with the axis hole of connection central rotating shaft, the clockwork spring setting as a result,
It in the cavity of the ontology and covers outside the central axle sleeve of the supporting plate, the supporting element is arranged in the supporting plate and institute
The outside junction of ontology is stated, i.e., the described supporting plate is connect at plane with the ontology and the clockwork spring.
The utility model has the following beneficial effects:
The utility model applicability is very strong, there is very big development prospect, and compared with prior art, the utility model is by axle sleeve
On the body, fagging plays supporting role, prevents the deformation of axle sleeve, and increase supporting plate and axis with the plastic fixation afterwards of fagging
The contact area of set reduces the pressure that axle sleeve receives, prevents the premature attrition of axle sleeve, improve the service life of entire wheel.
Below by drawings and examples, the technical solution of the utility model is described in further detail.
