Abstract
The utility model discloses a belt tensioner, which comprises a casing and a tensioner arm. The casing is internally equipped with a spring, the head end of the tensioner arm is in axial linkage with the casing through a central shaft sleeve, and the tail end of the tensioner arm is coaxially fixed with a belt pulley. The belt tensioner is characterized in that the outer end face of the casing is equipped with a mounting positioning hole. The utility model has the advantages of small vibration, stable operation, long service life and the like.
Description
Technical field
The utility model relates to a kind of belt tightener, specifically is meant a kind of belt tightener that is applicable to motor car engine.
Background technique
The main effect of the belt tightener of automobile is the drivign belt of devices such as tensioning automobile engine crankshaft belt pulley driving automobile water pump, power assistance pump for steering, generator, air conditioning pump, so that devices such as auto pump, power assistance pump for steering, generator, air conditioning pump keep proper functioning.Its main defective of existing belt tightener is to lack effective positioning means, and the stretcher Oscillation Amplitude is bigger during work, has a strong impact on the working life of interior belt of motor and belt tightener itself.
The model utility content
The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and provides a kind of vibration little, working stability, the belt tightener of long service life.
For achieving the above object, the technical solution of the utility model is to include housing, tension arms, be provided with spring in the described housing, the head end of described tension arms axially is linked by central axle sleeve and housing formation, and the coaxial belt pulley that is fixed with of the tail end of this tension arms, it is characterized in that: the exterior edge face of described housing is provided with the installing and locating hole.
Further being provided with is that described installing and locating hole has two, and these two installing and locating holes become same straight line with the axis hole of central axle sleeve.
Further being provided with is that described tension arms is provided with the switching hole.
Further being provided with is the flange that has been fixedly connected on the sidewall of head end of described tension arms, and described switching hole is arranged on this flange.
Advantage of the present utility model is: be provided with the installing and locating hole make after the installation of housing more solid and reliable, the vibration when having reduced work, the working life of having improved stretcher and belt.The tension arms that can use spanner to have an effect stretcher when needing the dismounting belt in the switching hole is set in addition draws back belt, make things convenient for the dismounting of belt.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
