Description
【Technical field】
The present invention relates to a kind of air compressor, more particularly, to the air compressor of belt transmission.
【Background technology】
Air compressor is used to provide for compressed air, with convenient to operate pneumatic tool such as pneumatic nail gun, sanding tool, spray
The instruments such as lacquerer's tool.In the prior art, air compressor drives flywheel turns using belt pulley by belt, there is belt fortune
Turn the phenomenon that path easily wanders off and then even come off, and belt axially confined in position it is relatively dead in the case of easy distortion fortune
Turn, wear and tear quickly, the life-span it is relatively low, the shortcoming based on prior art, the invention provides some improvement.
【The content of the invention】
It is not only difficult for drop-off but also can adaptively fine setting is anti-for position that problem to be solved by this invention is to provide a kind of set belt
Partially, the air compressor of belt distortion abrasion is suppressed.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that：
A kind of air compressor, including handle, the belt pulley for being fixed on machine shaft, flywheel, belt, belt pulley pass through skin
Band flywheel driven is rotated, and belt pulley has the first surface positioned at its periphery, around belt pulley axis, and flywheel, which has, is located at it
Periphery, the second surface around flywheel axis, the inner face of belt are posted by first surface and second surface and are provided with side by side
Some circle muscle positions, first surface is groove face and second surface is smooth surface, and first surface is provided with some belts circular respectively side by side
The annular groove of axis is taken turns, some grooves that some muscle position is embedded on belt pulley groove face and flywheel light is pressed on
Face.
The design coordinates belt of the inner face provided with multi-turn muscle position to use using groove face belt pulley, smooth surface flywheel, rotation process
In belt axial location can be limited by the groove of the circular belt pulley axis of groove face, suppress belt in rotation process middle position
Put and fall partially, beneficial to the defect for overcoming belt easily to be skidded off from smooth surface, and can prevent that belt from deviating from from the flywheel of smooth surface, meanwhile, light
The flywheel in face is facilitating the installation of belt (if belt pulley and flywheel all using belt easy to install is not allowed if groove face, if belt
Wheel and flywheel all using smooth surface then belt easily wander off, come off) while provide belt carry out fine position condition, even if skin
Band assembling fashionable dress it is inclined some, carry out adaptive fine position correction (if belt pulley is with flying in smooth surface after also operating
Wheel all using groove face then belt position it is relative be defined it is dead), deacclimatize, match belt in the position of belt pulley, it is to avoid belt
Biasing, rotating path distort and cause the abrasion of muscle position and distortion damage, improve belt life.
Further, smooth surface is the face of cylinder, on a first direction, and the inward flange of smooth surface inwardly exceeds the inward flange of groove face
And the outward flange of smooth surface outwards exceeds the outward flange of groove face, first direction is less than or waited parallel to machine shaft, the width of belt
In the width of groove face.
Further, the inward flange of groove face aligns with the inward flange of belt, the outward flange of groove face and the outward flange pair of belt
Together.
Further, smooth surface is the face of cylinder, on a first direction, and the inward flange of smooth surface inwardly exceeds the inward flange of belt
And the outward flange of smooth surface outwards exceeds the outward flange of belt, first direction is parallel to machine shaft.
Further, width B, A and the B difference that the width A of smooth surface is more than some muscle positions side by side are single muscle position
1.4 times to 2.8 times of mean breadth.
Further, flywheel include being located at lateral surface and medial surface inside and outside it, be connected smooth surface and lateral surface outside
The inner side chamfering face of side fillet surface, connection smooth surface and medial surface.
Further, described air compressor is additionally included in the clutch shaft bearing of eccentric setting, one end on flywheel and is configured at
The connecting rod of clutch shaft bearing, the piston positioned at the connecting rod other end, cylinder, the air accumulator to store the air being compressed by pistons, fly
Piston is driven to be moved back and forth in cylinder by connecting rod when wheel is rotated.
Further, described air compressor also includes support, the pump group part being assemblied on support and motor and flywheel
The fixed flywheel rotating shaft of phase, second bearing, pump group part include pump cover, piston, cylinder, and motor includes stator, rotor, the motor
Rotating shaft is a part for rotor, and flywheel rotating shaft is assemblied on support by second bearing.
Further, muscle position described in the groove backstop is to prevent muscle position from being slided outwards and inward against in groove face, muscle position
Press on smooth surface and be deformed, muscle position can and slid inward outside in smooth surface.
Further, the present invention also provides a kind of air compressor, including handle, belt pulley, flywheel, belt, belt pulley
By belt drive flywheel turns, belt pulley has the first surface for being used to coordinate, surround belt pulley axis with belt, flywheel
With the second surface to coordinate with belt, around flywheel axis, the inner face of belt is posted by first surface and the second table
Face and provided with side by side some circle muscle position, further, first surface is groove face and second surface is the face of cylinder, and first surface is set
There is groove of some rings side by side around belt pulley axis, muscle position is corresponded with groove, some muscle positions are embedded in pair
The groove answered and press on the flywheel face of cylinder.
