Description
Technical field
The utility model relates to the technical fields of air compressor crankcase, and in particular to a kind of U for air compressor crankcase
Shape crankshaft.
Background technique
Air compressor crankcase is the important composition component of air compressor machine, in crankshaft play give air cylinder piston for air compressor transmitting
The effect of power, to provide the power of work for air compressor machine, since centrifugal force is larger in rotation for crankshaft, common crankshaft exists
The offset that position inevitably occurs when rotation always influences the movement of piston, the crankshaft that the high-speed rotation of long term bias position makes
And the service life of cylinder piston reduces.
Utility model content
The purpose of this utility model is to provide a kind of U-shaped crankshafts for air compressor crankcase, to solve above-mentioned crankshaft
And cylinder piston service life reduce the technical issues of.
The utility model using following technical scheme in order to solve the above technical problems, realized:
A kind of U-shaped crankshaft for air compressor crankcase, it is described including front axle, rear axle and the U-shaped of centre driving portion
U-shaped driving portion is equipped with first connecting portion and second connecting portion, and rolling ring is equipped between first connecting portion and second connecting portion, described
Front axle is equipped with the fore bearing mounting portion of undergauge, and front axle top is equipped with belt pulley mounting portion, and the rear axle is equipped with undergauge
Rear bearing mounting portion.
Preferably, the junction of the first connecting portion and second connecting portion and U-shaped driving portion is equipped with chamfering.
Preferably, the rolling ring can make along U-shaped driving portion it is radial rolling.
Preferably, being equipped with preceding interconnecting piece between the front axle and U-shaped driving portion.
Preferably, being equipped with rear interconnecting piece between the rear axle and U-shaped driving portion.
Preferably, the U-shaped driving portion is equipped with the first balance portion and the second balance portion.
The beneficial effects of the utility model are:
(1) it is equipped with rotatable rolling ring among U-shaped driving portion, makes that first connecting portion and second is avoided to connect when crank rotation
Connecting rod in portion generates friction, keeps crank rotation more steady；
(2) U-shaped driving portion is equipped with the first balance portion and the second balance portion, reduces the weight difference of crankshaft two sides, makes its rotation
It is more stable；
(3) front axle is equipped with the fore bearing mounting portion of undergauge, and rear axle is equipped with the rear bearing mounting portion of undergauge, passes through front axle
It holds mounting portion and rear bearing mounting portion is connect with crankcase, make to engage when crank rotation with crankcase and front and back bearings, thus not
The offset of position can occur.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described further with reference to the accompanying drawing:
As shown, a kind of U-shaped crankshaft for air compressor crankcase, the U-shaped including front axle 1, rear axle 10 and centre
Driving portion 8, the U-shaped driving portion 8 are equipped with first connecting portion 7 and second connecting portion 5, first connecting portion 7 and second connecting portion 5
Between be equipped with rolling ring 6, the front axle 1 be equipped with undergauge fore bearing mounting portion 3,1 top of front axle be equipped with belt pulley mounting portion
2, the rear axle 10 is equipped with the rear bearing mounting portion 9 of undergauge, the first connecting portion 7 and second connecting portion 5 and U-shaped drives
The junction in dynamic portion 8 is equipped with chamfering, and the rolling ring 6 can make radial rolling, described front axle 1 and U-shaped along U-shaped driving portion 8
It is equipped with preceding interconnecting piece 13 between driving portion 8, rear interconnecting piece 14, the U are equipped between the rear axle 10 and U-shaped driving portion 8
Shape driving portion 8 is equipped with the first balance portion 11 and the second balance portion 12.
When the crank shaft rotates, due to being equipped with rotatable rolling ring among U-shaped driving portion, make to avoid the first company when crank rotation
Connecting rod in socket part and second connecting portion generates friction, and U-shaped driving portion is equipped with the first balance portion and the second balance portion, reduces crankshaft
The weight difference of two sides keeps crank rotation more steady, and front axle is equipped with the fore bearing mounting portion of undergauge, and rear axle is equipped with undergauge
Rear bearing mounting portion is connect by fore bearing mounting portion and rear bearing mounting portion with crankcase, when making crank rotation and crankcase
Engage with front and back bearings, so that the offset of position will not occur.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., is all contained in the protection of the utility model within novel spirit and principle
Within the scope of.
