Abstract
The utility model discloses an eccentric sliding sleeve with an oil gas pumping function for a scroll compressor. The eccentric sliding sleeve comprises an eccentric sliding sleeve body, wherein an end ring is arranged at one end of the eccentric sliding sleeve body; an eccentric shaft of a crankshaft is sleeved with the eccentric sliding sleeve body; a gap is formed in the end ring and is formed in one side close to the central axis of the crankshaft. According to the eccentric sliding sleeve disclosed by the utility model, the shortcomings of the conventional eccentric sliding sleeve are overcome; due to the oil gas pumping function of the eccentric sliding sleeve, a vortex disk bearing realizes an oil-gas supplying function, and oil gas can flow; the lubricating performance of the bearing is improved, and normal and reliable running of the compressor is guaranteed.
Description
Technical field
The utility model relates to a kind of eccentric sliding sleeve with pump oil gas function for scroll compressor.
Background technique
Conventionally in opening type scroll compressor, between crankshaft crank one end and whirlpool dish, mostly adopt eccentric sliding sleeve to carry out the driving to whirlpool dish, because will stretching out compressor, the bent axle the other end connects external drive, therefore can not make oil pump form to whirlpool dish bearing supplying lubricating oil, whirlpool dish bearing mainly relies on the oil gas in compressor cavity to enter on a small quantity bearing and is lubricated, lubrication effect is poor, is prone to bearing oil starvation state, has affected the normal reliable operation of compressor.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of eccentric sliding sleeve with pump oil gas function for scroll compressor, this eccentric sliding sleeve has overcome the defect of traditional eccentric sliding sleeve, by the pump oil gas function of this eccentric sliding sleeve, make whirlpool dish bearing increase oil gas supply, and it is mobile that oil gas is formed, improve bearing lubrication performance, guaranteed the normal reliable operation of compressor.
For solving the problems of the technologies described above, the utility model comprises eccentric sliding sleeve body for the eccentric sliding sleeve with pump oil gas function of scroll compressor, described eccentric sliding sleeve body one end is provided with end ring, described eccentric sliding sleeve body is sheathed on the eccentric shaft of bent axle, described end ring has breach, and described breach is located at a side nearest from crankshaft center axis.
Further, above-mentioned breach has directivity, and take crankshaft center and the eccentric sliding sleeve body line of centres as benchmark, the center of described breach is at the windward side of described eccentric sliding sleeve body running.
Further, above-mentioned breach open-angle is for being greater than 0 °, being less than 150 °.
Further, the angle of the outer end points place's radius of above-mentioned breach windward side and crankshaft center and the eccentric sliding sleeve body line of centres is in ± 90 °.
Because the utility model has adopted technique scheme for the eccentric sliding sleeve with pump oil gas function of scroll compressor, be that this eccentric sliding sleeve comprises eccentric sliding sleeve body, eccentric sliding sleeve body one end is provided with end ring, eccentric sliding sleeve body is sheathed on the eccentric shaft of bent axle, end ring has breach, and breach is located at a side nearest from crankshaft center axis.This eccentric sliding sleeve has overcome the defect of traditional eccentric sliding sleeve, by the pump oil gas function of this eccentric sliding sleeve, makes dish bearing in whirlpool increase oil gas supply, and it is mobile that oil gas is formed, and improves bearing lubrication performance, guaranteed the normal reliable operation of compressor.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the eccentric sliding sleeve schematic diagram with pump oil gas function of the utility model for scroll compressor;
Fig. 2 is that the A-A of Fig. 1 is to view;
Fig. 3 is the schematic diagram that this eccentric sliding sleeve is connected with bent axle;
Fig. 4 is the principle schematic of this eccentric sliding sleeve pump oil gas.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, the utility model comprises eccentric sliding sleeve body 1 for the eccentric sliding sleeve with pump oil gas function of scroll compressor, described eccentric sliding sleeve body 1 one end is provided with end ring 2, described eccentric sliding sleeve body 1 is sheathed on the eccentric shaft 5 of bent axle 4, described end ring 2 has breach 3, and described breach 3 is located at a side nearest from bent axle 4 central axis.
Further, above-mentioned breach 3 has directivity, take bent axle 4 centers and eccentric sliding sleeve body 1 line of centres as benchmark, and the windward side turning round at described eccentric sliding sleeve body 1 in the center of described breach 3.
Further, above-mentioned breach 3 open-angles are for being greater than 0 °, being less than 150 °.
Further, the angle of the outer end points 31 place's radiuses of above-mentioned breach 3 windward sides and bent axle 4 centers and eccentric sliding sleeve body 1 line of centres is in ± 90 °.
As shown in Figure 3, this eccentric sliding sleeve is sheathed on the eccentric shaft 5 of bent axle 4, and under the driving of crankshaft eccentric shaft 5, the spin axis of this eccentric sliding sleeve flexing axle 4 rotates; As shown in Figure 4, Oc is bent axle 4 centers, and Ot is this eccentric sliding sleeve center, any point on end ring 2 internal diameters of eccentric sliding sleeve, its movement locus is the circle take Oc as the center of circle, and its maximum radius is that end ring 2 internal diameters and offset sum, least radius are the poor of end ring 2 internal diameters and offset; Utilize the breach 3 on end ring 2, oil gas in compressor cavity is entered in eccentric sliding sleeve end ring 2 from breach 3 minor radius, utilize the centrifugal action of different radii in rotating, make oil gas from breach 3 rotations to large radius, and oil gas is discharged to the other end from the intermediate throughholes of eccentric sliding sleeve body 1, thereby play the effect of centrifugal pump, whirlpool dish bearing is played to good lubrication.The inwall of breach 3 one sides makes breach 3 become maximum angle with the windward side of oil gas with end ring 2 radiuses with the tangent meeting of end ring 2 inner ring, so that oil gas enters breach 3 is the most smooth and easy, at oil gas, enter into the interior rear flank of end ring 2, radius along end ring 2 inwall runnings is increasing, utilize the further oil supply air lift of centrifugal action for power, last from gathering near end ring 2 turning radius biggest places and being discharged to eccentric sliding sleeve body 1 the other end by the intermediate throughholes of eccentric sliding sleeve body 1, be whirlpool dish bearing portion, the lubricated of whirlpool dish bearing is provided.
This eccentric shift sleeve structure is simple, only at end ring, offers breach, makes this eccentric sliding sleeve play the effect of oil pump, for whirlpool dish bearing provides good lubricating, has overcome the defect of traditional eccentric sliding sleeve, has guaranteed the normal reliable operation of compressor.
