Abstract
The utility model relates to a double-cylinder lubrication-free swing air compressor that comprises a pair of cylinders, two cylinder swing elements corresponding to the cylinders, a crankshaft driven by a driving wheel, a pair of connecting rods which are driven by the crankshaft and are linked with the swinging element on one side. The swing air compressor is characterized in that the crankshaft is symmetrically provided with a front bell crank and a rear bell crank which are used for the connecting rods of the two cylinder swing elements that are respectively arranged on the front bell crank and the rear bell crank. The symmetric arrangement of the two bell cranks can result in the swinging of the two cylinder swing elements in the opposite directions; the driving force is more balanced; the operation is more stable; the impulsive load is low; and the structure can effectively prolong the service life of each friction pair, stabilize the operation of the machine, and reduce the failure rate of the relevant components.
Description
Technical field:
The utility model relates to air compressor, the oil-free pendulum type air compressor of more specifically saying so.
Background technique:
Air compressor is to provide the key equipment of source of the gas for moving the transportation powder grain material, belongs to revolution class machinery, and its drive mechanism is to be provided with according to four connecting rod crank rocking bar principles.Shown in Figure 1, the rotation of driving wheel 1 drives one-throw crankshaft 2 and rotates, make a pair of malaria 4 reciprocating, swept volume in the periodic variation cylinder body 5, thereby realize air-breathing and exhaust continuously, four active chambers utilize the accurate strip of paper used for sealing of graphitic carbon to seal mutually in the cylinder, and are lubricated by the Stamping Steel Ribbon self-lubrication between the movement parts surface of contact in the cylinder body, need not refuel.Therefore, the pure nothing oil of the pressurized air of discharge.
As shown in Figure 1, the driving mechanism of existing at present like product all is to adopt singly to turn connecting rod, promptly is provided with singly on the bent axle 2 that is driven by driving wheel 1 and turns, and drives corresponding to set two cylinder malarias, 4 reciprocally swingings of two cylinder bodies 5 by pair of links 3.The shortcoming of this driving mechanism is singly to turn to drive twin-tub and make two cylinder malarias 4 simultaneously to a direction swing, driving mechanism strength imbalance, and the running impulsive load is big, causes the machine shake easily and shortens working life of each friction pair.
The model utility content:
The utility model is for fear of above-mentioned existing in prior technology deficiency, a kind of balance of power that can keep driving mechanism is provided, reduce the impulsive load that turns round, reduce machine shake, thereby keep advantages of higher stability to improve the complete machine unlubricated swing air compressor of twin-tub in working life working life greatly to improve friction pair.
The technological scheme that the utility model technical solution problem is adopted is:
The utility model comprises a pair of cylinder body and the two cylinder malarias that are provided with corresponding to cylinder body, and the bent axle by drive wheel is set, and is linked with the malaria of a corresponding side respectively by the pair of links of crank-driven;
Structural feature of the present utility model is crank throw and an after crank before being symmetrical arranged on bent axle, crank shaft and after crank axle before the pair of links that is used for driving respectively two cylinder malarias is separately positioned on.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model adopts symmetrically arranged hyperbolic to turn structure, make the two cylinder malarias swing round about simultaneously of air compressor, make its driving force more keep weighing apparatus, it is more steady to turn round, impulsive load is little, can effectively prolong the working life of each friction pair, and the rate of fault of the more steady minimizing associated components that has a machine in operation.
Description of drawings:
Fig. 1 is the prior art structural representation.
Label among Fig. 1: 1 driving wheel, 2 one-throw crankshafts, 3 connecting rods, 4 malarias, 5 cylinder bodies.
Fig. 2 is the utility model structural representation.
Label among Fig. 2: crank shaft, 13 after crank axles before 6 driving wheels, 7 bent axles, 8 connecting rods, 9 swing arms, 10 malarias, 11 cylinder bodies, 12.
Below by embodiment, the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment:
Referring to Fig. 2, by existing structural type, the two cylinder malarias 10 that setting in the present embodiment also comprises a pair of cylinder body 11 and is provided with corresponding to cylinder body 11 are provided with the bent axle 7 that is driven by driving wheel 6, and the pair of links 8 that is driven by bent axle 7 links with the malaria 10 of a corresponding side respectively.
Different is with prior art, in the present embodiment, and crank throw and after crank before on bent axle 7, being symmetrical arranged, crank shaft 12 and after crank axle 13 before the pair of links 8 that is used for driving respectively two cylinder malarias 10 is separately positioned on.
Shown in Figure 2, give two-throw crank shaft 7 by driving wheel 6 with transmission of power, drive malaria 10 by two-throw crank shaft 7 move toward one another drivening rods 8 by swing arm 9 again and make periodicity to-and-fro motion change cylinder body 11 volumes with continuous generation pressurized air.Whole motion process strength is kept weighing apparatus, and running steadily shakes for a short time, has effectively improved complete machine and each friction pair working life.
