The utility model discloses can effectually prevent that the belt from deviating from, through setting up the wearing layer, the wearing layer can reduce the wearing and tearing volume on race surface like this, has avoided causing wearing and tearing to the belt, through setting up first dust exhaust groove, second dust exhaust groove, the belt pulley can be discharged the inside dust of belt pulley at at a high speed rotatory in -process through first dust exhaust groove, second dust exhaust groove like this, can play dirt -proof effect by furthest, prolongs the life of belt pulley.
Description
Technical field
The utility model relates to technical field of automobile, particularly relates to a kind of car air conditioner belt pulley.
Background technique
In country of China newest standards " term and definition of automobile and trailer type " (GB/T3730.1-2001) to automobile just like giving a definition: by motivational drive, there is the vehicle of the non-track carrying of more than 4 or 4 wheels, be mainly used in: carrying personnel and (or) goods; The vehicle of traction carrying personnel and (or) goods; Specific use.
Automobile air controlling device is called for short car air conditioner.For the temperature in automobile bodies, humidity, air cleanliness and air flow adjustment with control in the optimum state, take environment for occupant provides comfortable, reduce journey tired; For driver creates good operating conditions, to guaranteeing the ventilation plant that safe driving plays an important role.Generally comprise refrigeration plant, heating installation and compound ventilation air-changing device.This combined unit takes full advantage of the limited space of automotive interior, and structure is simple, and convenient operation is modern cars air-conditioning system popular in the world.
Common belt pulley 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 belt grooves after a long time use surface is is easily worn and torn, so easy wearing and tearing are caused to belt surface, affects belt working life, while belt pulley inside the dust of accumulation not easily discharge.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of car air conditioner belt pulley.
The utility model is achieved through the following technical solutions:
A kind of car air conditioner belt pulley, comprise pulley body, described pulley body central position is provided with through hole, described pulley body outer circumference direction is provided with several belt grooves, the V-shaped shape of described belt grooves, go up and be positioned at belt grooves one end outside described pulley body and be provided with spacing block set, each belt grooves madial wall described is provided with wearing layer, the first dust discharging grooves and several the second dust discharging grooves on described pulley body interior bone sidewall.
As optimal technical scheme of the present utility model, described spacing block set is rectangular or semicircle.
As optimal technical scheme of the present utility model, described wearing layer covers on each belt grooves madial wall, and thickness is 0.1mm ~ 0.5mm.
As optimal technical scheme of the present utility model, described first dust discharging grooves, the second dust discharging grooves are skewed layout.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, and reasonable in design, the utility model is by arranging spacing block set, and such spacing block set can effectively prevent belt from deviating from; By arranging wearing layer, such wearing layer can reduce the wear extent on belt grooves surface, avoids and causes wearing and tearing to belt; By arranging the first dust discharging grooves, the second dust discharging grooves, such belt pulley is in high-speed rotation, the dust of belt pulley inside can be discharged through the first dust discharging grooves, the second dust discharging grooves, dust-proof effect can be played to greatest extent, extend the working life of belt pulley.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of car air conditioner belt pulley, comprise pulley body 1, described pulley body 1 central position is provided with through hole 2, described pulley body 1 outer circumference direction is provided with several belt grooves 3, the V-shaped shape of described belt grooves 3, go up and be positioned at belt grooves 3 one end outside described pulley body 1 and be provided with spacing block set 4, wherein said spacing block set 4 is rectangular or semicircle, and such spacing block set 4 can effectively prevent belt from deviating from.Each belt grooves 3 madial wall described is provided with wearing layer 5, wherein said wearing layer 5 covers on each belt grooves 3 madial wall, and thickness is 0.1mm ~ 0.5mm, such wearing layer 5 can reduce the wear extent on belt grooves 3 surface, avoids and causes wearing and tearing to belt.
First dust discharging grooves 6 and several second dust discharging grooves 7 on described pulley body 1 interior bone 2 sidewall, wherein said first dust discharging grooves 6, second dust discharging grooves 7 is in skewed layout, and the degree of depth of the first dust discharging grooves 6, second dust discharging grooves 7 is 0.3mm ~ 1mm, such belt pulley is in high-speed rotation, the dust of belt pulley inside can be discharged through the first dust discharging grooves 6, second dust discharging grooves 7, dust-proof effect can be played to greatest extent, extend the working life of belt pulley.
In description of the present utility model, it will be appreciated that, term " orientation or the position relationship of the instruction such as " center ", " top ", " end ", " interior ", " outward " they be based on orientation shown in the drawings or position relationship; be only the utility model and simplified characterization for convenience of description; instead of instruction or imply the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
