There are first connecting portion and second connecting portion, the first rolling ring, second U-shaped are equipped between first connecting portion and second connecting portion
Driving portion is equipped with third interconnecting piece and the 4th interconnecting piece, and the second rolling ring is equipped between third interconnecting piece and the 4th interconnecting piece, described
Front axle be equipped with undergauge fore bearing mounting portion, front axle top be equipped with belt pulley mounting portion, the rear axle be equipped with undergauge
Rear bearing mounting portion.
Preferably, the junction of the first connecting portion, second connecting portion and U-shaped driving portion is equipped with chamfering.
Preferably, the junction of the third interconnecting piece, the 4th interconnecting piece and the second U-shaped driving portion is equipped with chamfering.
Preferably, first rolling ring can be made radial rolling along the first U-shaped driving portion, the second rolling ring can be along
Two U-shaped driving portions are made radial rolling.
Preferably, being equipped with preceding interconnecting piece between the front axle and the second U-shaped driving portion.
Preferably, being equipped with rear interconnecting piece between the rear axle and the first U-shaped driving portion.
Preferably, the first U-shaped driving portion is equipped with the first balance portion, the second U-shaped driving portion is equipped with 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, while both ends are equipped with the first balance portion and the second balance portion, keep crank rotation more steady；
(2) it is equipped with double drive portion, and contrary, double cylinders can be connected, an axis drives twin-tub movement, meets double cylinder need
It asks；
(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 dual U-shaped crankshaft for air compressor crankcase, including front axle 1, rear axle 10 and centre the
One U-shaped driving portion 8 and the second U-shaped driving portion 15, and the first U-shaped driving portion 8 and the second U-shaped driving portion 15 are contrary, it is described
The first U-shaped driving portion 8 be equipped with first connecting portion 7 and second connecting portion 5, be equipped between first connecting portion 7 and second connecting portion 5
First rolling ring 6, the second U-shaped driving portion 15 are equipped with third interconnecting piece 12 and the 4th interconnecting piece 14,12 He of third interconnecting piece
The second rolling ring 13 is equipped between 4th interconnecting piece 14, the front axle 1 is equipped with the fore bearing mounting portion 3 of undergauge, 1 top of front axle
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, the
The junction of two interconnecting pieces 5 and the first U-shaped driving portion 8 is equipped with chamfering, the third interconnecting piece 12, the 4th interconnecting piece 14 and the
The junction of two U-shaped driving portions 15 be equipped with chamfering, first rolling ring 6 can make along the first U-shaped driving portion 8 it is radial rolling,
