Abstract
The utility model relates to a kind of belt pulley, especially relates to a kind of car air conditioner belt pulley.Its belt pulley mainly solved existing for prior art is long for service time one, and after belt is worn and torn, belt is easier to deviate from from belt grooves, causes belt slippage, and the location of whole belt pulley is more inaccurate, the technical problem of the poor grade of dust-proof effect.The utility model comprises pulley body (1), the middle part rolling of described pulley body (1) has some belt grooves (2), the top being positioned at outermost two belt grooves is provided with to projecting inward spacing block set (3), the pulley body at belt grooves (2) two ends is provided with boss (4), and the height of boss is greater than belt grooves upper end level.
Description
Technical field
The utility model relates to a kind of belt pulley, especially relates to a kind of car air conditioner belt pulley.
Background technique
Automobile air conditioner compressor is by drivign belt wheel drive, and existing transmission pulley comprises belt pulley and is contained in the drive plate in belt pulley, and belt is around over pulleys carried, and drive plate is provided with wheel hub, and wheel hub connects air condition compressor main shaft.Chinese patent discloses a kind of generator and air condition compressor belt pulley wheel (Authorization Notice No.: CN203892015U), comprise the water pump pulley be arranged on diesel pump, be arranged on the air condition compressor belt pulley on the air-conditioning bracket of front end, generator pulley, idle pulley and poly Vbelt, it is characterized in that: described water pump pulley is driving wheel, idle pulley is positioned at the outside of poly Vbelt, between air condition compressor belt pulley and generator pulley, water pump pulley, air condition compressor belt pulley, the front-end face of idle pulley and generator pulley is all in same end face I, ear end face is in same end face II, between end face I and end face II, with the arbitrary plane of water pump pulley axes normal respectively with generator pulley, idle pulley, three crossing point of axes of air condition compressor belt pulley form V-shaped line I, poly Vbelt wrap angle sigma is 180 °-220 °, poly Vbelt cornerite β is 160 °-180 °, between end face I and end face II, with the arbitrary plane of idle pulley axes normal respectively with water pump pulley, three crossing point of axes of generator pulley and air condition compressor belt pulley form V-shaped line II.But this belt pulley is long for service time one, and after belt is worn and torn, belt is easier to deviate from from belt grooves, causes belt slippage, and the location of whole belt pulley is more inaccurate, and dust-proof effect is poor.
Model utility content
The utility model is to provide a kind of car air conditioner belt pulley, its belt pulley mainly solved existing for prior art is long for service time one, after belt is worn and torn, belt is easier to deviate from from belt grooves, cause belt slippage, and the location of whole belt pulley is more inaccurate, the technical problem of the poor grade of dust-proof effect.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Car air conditioner belt pulley of the present utility model, comprise pulley body, the middle part rolling of described pulley body has some belt grooves, the top being positioned at outermost two belt grooves is provided with to projecting inward spacing block set, the pulley body at belt grooves two ends is provided with boss, and the height of boss is greater than belt grooves upper end level.When belt may wear to a certain degree, its diameter can diminish, and therefore it easilier deviates from from belt grooves, arranges to projecting inward spacing block set, can be limited in belt grooves by belt, prevent it from deviating from the top of belt grooves.Boss can limit the position of belt.
As preferably, described boss has location arc groove.Belt pulley, when assembling, can position according to location arc groove, overcomes in the past by the complexity of step location.The diameter of location arc groove can be 2mm.The pulley end outer surface of arc groove one end, location can be provided with chamfering.
As preferably, one end of the endoporus of described pulley body has circular arc seal groove.Seal ring can be installed in circular arc seal groove, thus the dust that can prevent air-conditioning from producing enters into belt pulley inside.
As preferably, the inwall of described pulley body has multiple vacuum chamber, the width of vacuum chamber inside is greater than the width of its opening.The dust that air-conditioning produces is when belt pulley rotates because centrifugal action can be inhaled in vacuum chamber, and because vacuum chamber opening is less, therefore grit can be retained in vacuum chamber, thus reaches the effect of dedusting.
Therefore, the utility model arranges spacing block set in belt grooves, can prevent belt from deviating from, and utilize circular arc seal groove and vacuum chamber, dust-proof effect can be played to greatest extent, extend the working life of belt pulley, location is comparatively accurate, simple and reasonable for structure.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is A portion structure for amplifying schematic diagram of Fig. 1.
Component, position and numbering in figure: pulley body 1, belt grooves 2, spacing block set 3, boss 4, location arc groove 5, circular arc seal groove 6, vacuum chamber 7.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the car air conditioner belt pulley of this example, comprise pulley body 1, as shown in Figure 1, Figure 2, the middle part rolling of pulley body has some belt grooves 2, the top being positioned at outermost two belt grooves is provided with to projecting inward spacing block set 3, the pulley body at belt grooves 2 two ends is provided with boss 4, and the height of boss is greater than belt grooves upper end level.Boss has location arc groove 5.One end of the endoporus of pulley body has circular arc seal groove 6.The inwall of pulley body has multiple vacuum chamber 7, the width of vacuum chamber inside is greater than the width of its opening.
During use, whole belt pulley is encased on the transmission shaft of air condition compressor.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among the scope of the claims of the present utility model.
