In pulley drive process, easily suck a large amount of dust in side.
In order to solve above-mentioned technical problem, Chinese patent CN105042036A discloses a kind of compressor pulley used for automobile air conditioning, this compressor pulley used for automobile air conditioning includes pulley body, caulking groove, outer shroud, convex body, dust cap, described pulley body is provided with caulking groove, pulley body and outer shroud connect by caulking groove is fixing；The described fluted structure of outer shroud arranged outside；Described outer shroud inside edge is provided with the bulge-structure corresponding with the caulking groove in pulley body；The top, side of described belt pulley is provided with convex body, and equipped with the dust cap corresponding with belt pulley；Convex body in described dust cap and belt pulley is bolted.
But above-mentioned prior art still suffers from following technological deficiency:
It is bolted, it is necessary on dust cap and convex body, process corresponding screw thread respectively, and once screw thread process completes, described dust cap and belt pulley just can only be fixed by the bolt of a kind of specification, install and are restricted.
Utility model content
This utility model is intended to provide a kind of belt pulley retention mechanism installing less-restrictive.
Belt pulley retention mechanism in this programme, including pulley body and dust cap, the outer peripheral face of pulley body is provided with caulking groove, and described pulley body outer sheath is provided with outer shroud, and the inwall of described outer shroud is provided with and the convex key of described caulking groove grafting；The side of described outer shroud is provided with convex body, fixing installation set it is provided with between described dust cap and described convex body, described set of installing includes a hollow sleeve and is fixedly arranged on the flat bolster of hollow sleeve one end, the other end of described hollow sleeve is provided with the spring steel plate that circumference is distributed in hollow sleeve, the length direction of spring steel plate is perpendicular with the axis direction of described hollow sleeve, being provided with mean for, on described dust cap and convex body, the installing hole that described hollow sleeve penetrates, described dust cap and convex body are clamped between described flat bolster and spring steel plate.
Adopt the technical solution of the utility model, have the following technical effect that
Described dust cap and convex body are clamped between flat bolster and spring steel plate, cannot loosen between such dust cap and convex body.Bolt is replaced by the installation set with flat bolster Yu spring steel plate, thus offer screw thread without on dust cap and convex body, have only to arrange on dust cap with convex body for described set of installing by installing hole, and the size of installing hole is also not necessarily intended to consistent with the diameter installing set, it is only necessary to be a bit larger tham the diameter installing set.
Therefore, adopting and the fixing design of set is installed than the Fixed Design adopting bolt, the required precision of its dimensioned is relatively low, it is allowed to adopts the installation set of different size (as long as diameter is less than installing hole) to be fixedly connected, and is easily installed.
Further, described hollow sleeve is provided with female thread, is connected to bolt in described hollow sleeve.
Improvement herein, it is possible to compatible with bolt, namely with installing after set reinforces, it is also possible to increases bolt and adds further and be solidly connected.
Further, described flat bolster is provided with projection, and described projection is positioned at flat bolster on the side of described convex body.
Arranging projection at flat bolster on the side of described convex body, no matter described flat bolster is for contacting with convex body or contacting with dust cap, and described projection can prevent flat bolster from sliding relative to convex body or dust cap.
Further, described flat bolster is regular hexagon.
Described flat bolster is arranged to regular hexagon, is conducive to being hold by one hand operation.
