Summary of the invention
The utility model is at the diesel-oil vehicle dynamo belt expansion tightening wheel assembly above shortcomings of conventional design, provides that a kind of product antivibration coefficient height, sealing are good, performance safety, reliable and stable diesel-oil vehicle dynamo belt expansion tightening wheel assembly.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of diesel-oil vehicle dynamo belt expansion tightening wheel assembly comprises frames and work rocking arm, described frames and the formation that links to each other of work rocking arm, described joint has a cavity, is provided with both arms flexion torsion spring in the described cavity; Be provided with a central shaft at itself and work rocking arm connecting place on the described frames, described central shaft links to each other with frames; Have a center hole at itself and frames connecting place on the described work rocking arm, be provided with first rolling bearing and second rolling bearing in the described center hole.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, the described first Mounting of Rolling Contact Bearing position is provided with the first metal plain cushion, and the described second Mounting of Rolling Contact Bearing position is provided with the second metal plain cushion.
Further, described frames and the junction that links to each other of work rocking arm are provided with a plastic seal and intercept and enclose.
Further, described frames links to each other with the work rocking arm by fastening screw.
Further, be provided with metallic sealed cover below the described fastening screw.
Further, the end of described work rocking arm is provided with drive wheel, and described drive wheel top is provided with the metal dust cover.
Further, described drive wheel is installed in the end of work rocking arm by fastening screw.
Further, the installation of described both arms flexion torsion spring exposes the position, hole and is provided with rubber closure.
The beneficial effects of the utility model are: the utility model diesel-oil vehicle dynamo belt expansion tightening wheel assembly forces by both arms flexion torsion spring and reverses, drive work rocking arm and drive wheel are regulated the expanding force of belt under different tightness automatically, make the transmission system stability and safety reliable; The structure that assembles of the utility model frames, the rocking arm of working, the product antivibration coefficient that doubled has been stopped the phenomenon of conventional this product work rocking arm skew and split, has improved working life; In addition, the utility model is provided with a plastic seal and intercepts circle in frames, work rocking arm junction, on the mounting hole site of torsion spring angle, rocking arm upper end, be provided with rubber closure, thereby improved sealability, stopped to cause to reduce the phenomenon that life of product reduces and taken place because of sealing is bad; The utility model can be regulated the tensioner rate and the tensioner rate of belt under the different operating state of diesel car dynamo belt, thereby guarantees dynamo belt transmission driving force normal when.
