Description

A kind of fuel feeding bent axle and use the enclosed and reciprocatable compressor of this bent axle
[technical field]
The present invention relates to the oil feeding mechanism of compressor, relate in particular to a kind of fuel feeding bent axle and use the enclosed and reciprocatable compressor of this bent axle.
[background technique]
The closed compression machine all has oil feeding mechanism; Oil feeding mechanism is to be used to provide sufficient lubricating oil, and the secondary friction and take away frictional heat of when compressor operating, reducing friction reduces compressor noise; Also play seal clearance simultaneously, guarantee compressor proper functioning and long-term operation.As depicted in figs. 1 and 2, be a kind of closed compression machine and oil feeding mechanism thereof commonly used, oil feeding mechanism is a bent axle 1; Lubricant oil is inhaled into the main oil-hole 2 that bent axle 1 is axially offered, and under centrifugal action, the wall oilhole 3 that lubricant oil is radially offered from bent axle 1 flows out; Get into bent axle 1 helical oil groove 4, lubricant oil rises to axle journal along helical oil groove 4, flows into the inclined hole 7 that is communicated with crank 6 through axle journal radial hole 5; The inclined hole 7 that tilts to offer in the centrifugal action lower edge rises to crank 6; Thereby give crank 6 fuel feeding, and the lubricant oil that spills through crank 6 rotations forms the effect of lubricating and sealing to parts such as cylinder and piston and each surface.This common structure also need be offered exhaust passageway, like secondary straight hole of axially offering among Fig. 18 and axial inclined hole 9.When compressor just started, the solubility of refrigeration agent in lubricant oil reduced, and had more refrigerant gas and from lubricant oil, separated out; Secondary straight hole 8 can make this part gas discharge fast with the exhaust passageway of axially inclined hole 9 formation; Be unlikely to block the oil circuit of fuel feeding, make when compressor start as early as possible the working part surface is formed fuel feeding, not fuel feeding or the not enough situation of fuel feeding in the time of can not starting; But exhaust passageway has increased the manufacturing procedure of bent axle, has reduced the efficient of bent axle processing.
[summary of the invention]
It is a kind of simple in structure, easy to process that the present invention provides, and reliable operation can effectively improve the fuel feeding bent axle of bent axle work efficiency and use the enclosed and reciprocatable compressor of this bent axle.
In order to realize the foregoing invention purpose, the technological scheme that the present invention adopts is:
A kind of fuel feeding bent axle; The axial centre bottom of this bent axle offers main oil-hole; Outer wall top offers helical oil groove; Radially be provided with the wall oilhole of conducting between main oil-hole and the helical oil groove, the crank center of bent axle offers oil storage tank, crank radially offer the diffusing oil groove hole that is communicated with oil storage tank; Offering direct connection main oil-hole and oil storage tank on the axial direction of the circumferential eccentric part of bent axle and the make progress eccentric oil duct of straight line shape of pump oil of centrifugal force capable of using when bent axle rotates.
The eccentric oil duct of said straight line shape be directly on connection main oil-hole and the crank oil storage tank and with the oil duct of bent axle parallel to an axis.
The bottom and the bent axle parallel to an axis of the eccentric oil duct of said straight line shape, top tilt vertically and with crank on oil storage tank be communicated with, the eccentric oil duct of upper and lower part has a slanted angle.
A kind of enclosed and reciprocatable compressor, this compressor uses above-mentioned fuel feeding bent axle, and this compressor is applicable to refrigeration refrigerator.
The invention has the beneficial effects as follows:
The present invention has cancelled the exhaust inclined hole of bent axle on the enclosed and reciprocatable compressor commonly used; And at the radial hole of crankshaft journal and spiral groove end; On bent axle is axial, offer the eccentric oil duct of eccentric axial straight line shape; Bent axle than common structure on processing technology is simpler, improved the efficient that the bent axle manufacturing is produced, and it is reliable to oil.

[embodiment]
Extremely shown in Figure 6 like Fig. 3; A kind of fuel feeding bent axle; The axial centre bottom of this bent axle offers main oil-hole 10, and outer wall top offers helical oil groove 11, radially is provided with the wall oilhole 12 of conducting between main oil-hole 10 and the helical oil groove 11; Crank 13 centers of bent axle offer oil storage tank 14, crank 13 radially offer the diffusing oil groove hole 15 that is communicated with oil storage tank 14; Offering direct connection main oil-hole 10 and oil storage tank 14 on the axial direction of the circumferential eccentric part of bent axle and the make progress eccentric oil duct 16 of straight line shape of pump oil of centrifugal force capable of using when bent axle 13 rotates.
Embodiment one
Like Fig. 3 to shown in Figure 4, the eccentric oil duct 16 of straight line shape be directly be communicated with oil storage tank on main oil-hole and the crank and with the oil duct of bent axle parallel to an axis, the manufacturing of these straight line shape off-centre oil duct 16 more convenient bent axles.
Embodiment two
Extremely shown in Figure 6 like Fig. 5; Be with embodiment's one difference; The bottom 16 of the eccentric oil duct 16 of straight line shape ' with bent axle parallel to an axis, top 16 " inclination vertically and with crank on oil storage tank 14 be communicated with, the eccentric oil duct of upper and lower part (16 ", 16 ') has a slanted angle; The eccentric oil duct of this straight line shape makes that to offer vittate crankshaft strength better, and working life is more reliable.
The fuel feeding bent axle of the utility model can be widely used on the enclosed and reciprocatable compressor, is particularly useful for refrigeration refrigerator.When compressor just starts; The solubility of refrigeration agent in lubricant oil reduces; Have more refrigerant gas and from lubricant oil, separate out, gas can be discharged from the radial hole on crank 13 and the bent axle, the eccentric oil of straight line shape and these two paths of spiral chute fast, can not cause the oil circuit that blocks fuel feeding; Can be when compressor start as early as possible the working part surface be formed fuel feeding, not fuel feeding or the not enough situation of fuel feeding in the time of can not starting.
When compressor operating, the pasta in the bent axle main oil-hole 10 is parabolic and distributes, and on the one hand, lubricant oil flows to bent axle spiral chute 11 from radial wall oilhole 12 under the effect of rotary centrifugal force, and rises along helical oil groove 11, forms fuel feeding for the rack bearing of compressor; On the other hand; Flow of lubricant is to the eccentric oil duct 16 of straight line shape; Rise up to crank in the eccentric oil duct of straight line shape 16 outsides in the centrifugal action lower edge, forms the fuel feeding to crank 13, and lubricant oil splashes through eccentric mass through the oil groove hole 15 of loosing and forms part fuel feeding such as cylinder and pistons simultaneously.
The above embodiment for preferred embodiment of the present invention, is not to limit practical range of the present invention with this just, and the equivalence that all shapes according to the present invention, structure and principle are done changes, and all should be covered by in protection scope of the present invention.
