Abstract
The utility model discloses a kind of tension pulley support, comprise main shaft and belt pulley, described main shaft and belt pulley all adopt metal material to make, described collar bush has axle sleeve, and described axle sleeve outer wall is arranged with bearing, and the both sides of described bearing are provided with dust cover, described dust cover adopts steel plate to make, on described bearing outer wall, cover has belt pulley, and described belt pulley offers the groove of sheathed belt, the subtended angle of described groove is 36 degree.The utility model overall structure is simple, and technique is meticulous, and main shaft and belt pulley all adopt metal material to make, and durable wear, is provided with dust cover in the both sides of bearing, can effectively protect bearing not by outside contamination, extend its working life.
Description
Technical field
The utility model relates to automotive air-conditioning system field, specifically a kind of tension pulley support for fixing air-conditioning condenser.
Background technique
Tension pulley support is mainly used in tensioning compressor belt, and therefore it is usually subject to the extruding of belt, rubs throughout the year, makes it easily be worn, and shortens its working life; Simultaneously its bearing of existing Idle wheel and axle sleeve all do not add any for the protection of shield, a large multiple bearing ancient piece of jade, round, flat and with a hole in its centre is all directly contact with air, is easily stained with and invites grieshoch or oxidized, have impact on the working life of whole Idle wheel.
Model utility content
The purpose of this utility model is the defect overcoming above-mentioned prior art, provides a kind of wear resistance good, the tension pulley support of high life.
The technical solution of the utility model is achieved in that a kind of tension pulley support, comprise main shaft and belt pulley, described main shaft and belt pulley all adopt metal material to make, described collar bush has axle sleeve, and described axle sleeve outer wall is arranged with bearing, and the both sides of described bearing are provided with dust cover, described dust cover adopts steel plate to make, on described bearing outer wall, cover has belt pulley, and described belt pulley offers the groove of sheathed belt, the subtended angle of described groove is 36 degree.
Further, described bearing is fixed on described main shaft by nut.
Particularly, packing ring is provided with between described nut and dust cover.
The utility model overall structure is simple, and technique is meticulous, and main shaft and belt pulley all adopt metal material to make, durable wear; In the both sides of bearing, dust cover is installed, can effectively protects bearing not by outside contamination, extend the working life of whole tension pulley support.
Accompanying drawing explanation
Fig. 1 is the sectional view of a kind of tension pulley support of the utility model.
Embodiment
Below in conjunction with accompanying drawing, concrete case study on implementation of the present utility model is illustrated:
As shown in Figure 1, a kind of tension pulley support, comprises main shaft 1 and belt pulley 2, and described main shaft 1 and belt pulley 2 all adopt metal material to make, durable wear, long service life.Described main shaft 1 cover has axle sleeve 3, described axle sleeve 3 outer wall is arranged with bearing 4, the both sides of described bearing 4 are all provided with dust cover 5, described dust cover 5 adopts steel plate to make, described dust cover 5 can avoid grieshoch to fall on bearing 4 ancient piece of jade, round, flat and with a hole in its centre effectively, avoids bearing 4 directly and extraneous contact simultaneously, decreases the pollution of bearing 4, described bearing 4 surface also scribbles oiling agent, extends its working life.On described bearing 4 outer wall, cover has described belt pulley 2, and described belt pulley 2 offers the groove 6 of sheathed belt, described groove 6 is for installing belt and tightening belt, and the subtended angle of described groove 6 is 36 degree, and precision precisely makes belt fixing more firm.Described bearing 4 is fixed on described main shaft 1 by nut 7, is provided with packing ring 8 between described nut 8 and dust cover 5, and described packing ring 8 is for sealing off gap.Whole tension pulley support is arranged on for fixing on supporting frame by bolt, and described bolt, nut and dust cover surface are all coated with color zinc, and not only outward appearance has color and luster to have protective action simultaneously.
As described above, be only preferred embodiment of the present utility model, when can not limit the scope of the utility model enforcement with this, namely the simple equivalence change generally done according to the utility model claim and model utility description with modify, all still belong in scope that the utility model patent contains.
