Abstract
The utility model discloses a crankshaft applied to a refrigeration compressor. The crankshaft consists of three parts, i.e. a long shaft, a balance block and an eccentric shaft. An oil inlet hole and a transitional oil hole connected with the oil inlet hole are axially reserved in the end part of the long shaft respectively. A radial vent hole is reserved in the middle section of the transitional oil hole. A radial oil outlet hole is reserved in the tail part of the transitional oil hole. A spiral oil groove is reserved in the rear section of the long shaft. An inclined oil passing hole is reserved in the balance block. One end of the spiral oil groove is connected with the radial oil outlet hole. The crankshaft is characterized in that: the oil inlet hole is formed in one end of the inclined oil passing hole, and extends to the tail part of the long shaft to be connected with the spiral oil groove; the other end of the inclined oil passing hole extends to the middle section of the eccentric shaft, and forms an oil outlet in the surface of the eccentric shaft; an oil outlet groove is also reserved in one side of the eccentric shaft; and one end of the oil outlet groove is connected with the oil outlet of the inclined oil passing hole. The problems of insufficient eccentric shaft strength, high friction power consumption of the refrigeration compressor, serious abrasion of parts of a kinematic pair, and the like caused by a cavity oil chamber in the eccentric shaft of the conventional crankshaft are solved; and the crankshaft is widely used as the crankshaft of the refrigeration compressor.
Description
(1) technical field: the utility model relates to the component of refrigeration compressor, especially a kind of bent axle that is applied to refrigeration compressor.
(2) background technique: as power source, by the rotor banding dynamic crankshaft rotation of motor, bent axle cooperates with connecting rod refrigeration compressor, and piston is moved reciprocatingly in cylinder block cylinder hole, thereby realizes the refrigeration cycle of refrigeration compressor with motor.Compressor inner components high-speed motion; Need good lubricating between each kinematic pair and the component; If lubricated insufficient, the component that constitute kinematic pair have wearing and tearing, have increased the friction power loss of refrigeration compressor greatly; Reduced the COP of compressor, more serious meeting causes the generation of the stuck phenomenon of refrigeration compressor.
are present, in order to satisfy the good lubricating condition of refrigeration compressor, generally adopt crankshaft eccentric formula centrifugal pump oil structure in the refrigeration compressor industry, and this pump oil structure is made up of fuel sucking pipe and bent axle.Fuel sucking pipe is pressed in the bent axle oil inlet hole, and existing bent axle concrete structure is as shown in Figure 1, when crankshaft rotating; Rely on action of centrifugal force; Refrigerator oil in the compressor housing in the oil sump will enter into the oil inlet hole of bent axle along fuel sucking pipe, and the transition oilhole of flowing through successively, radially filler opening, oblique oil through, cavity grease chamber and the oil outlet of oil outlet, helical oil groove, oblique oil through make between each component of refrigeration compressor and obtain sufficient lubrication; This kind oil pumping system effect is remarkable; Lubricated fully, but, design according to this kind oil circuit when the offset of eccentric crankshaft greatly the time; Cavity grease chamber in the eccentric shaft will destroy the intensity of eccentric shaft, make the intensity of eccentric shaft can't satisfy the designing requirement of refrigeration compressor.If increase the diameter of eccentric shaft, though can solve the strength problem of the eccentric shaft of bent axle, the increase of eccentric shaft diameter will inevitably make the connnecting rod big end that cooperates with eccentric shaft increase, and has increased the manufacturing cost of refrigeration compressor, does not very calculate.
(3) summary of the invention: the purpose of the utility model is exactly that the eccentric shaft inside that will solve traditional bent axle has the cavity grease chamber and causes the eccentric shaft insufficient strength; Problems such as the big parts wear with lubricated insufficient kinematic pair that causes of the friction power loss of refrigeration compressor is serious provide a kind of bent axle that is applied to refrigeration compressor.
The concrete scheme of
the utility model is: improve to traditional bent axle, it is made up of major axis, equilibrium block and eccentric shaft three parts, and the major axis end has oil inlet hole and the transition oilhole that links to each other with oil inlet hole vertically; Transition oilhole stage casing has rod radial air vent, and transition oilhole afterbody has radially oil outlet, and the major axis back segment has helical oil groove; Have oblique oil through in the equilibrium block; Helical oil groove one end links to each other with oil outlet radially, and it is characterized in that: an end of said oblique oil through is a filler opening, and this filler opening extends to the major axis afterbody and links to each other with helical oil groove; The oblique oil through the other end extends to the stage casing of eccentric shaft; And, also having out oil groove in eccentric shaft one side at eccentric shaft surface formation oil outlet, an end that goes out oil groove links to each other with the oil outlet of oblique oil through.
in order to reach best lubrication effect, the pore size of the oblique oil through in the utility model is φ 2～φ 3.5mm.
The filler opening and the oil outlet at oblique oil through two ends are 180 ° of interlaced arrangement described in
the utility model.
The oil groove that goes out described in
the utility model on the eccentric shaft is in tilted layout on the surface of eccentric shaft.
the utility model has saved the cavity grease chamber; Also having one on the eccentric shaft goes out oil groove and links to each other with the oil outlet of oblique oil through; During compressor operation, the refrigerator oil in the compressor housing can get into oil inlet hole along fuel sucking pipe like this, flow through successively then the transition oilhole, radially filler opening, oblique oil through, the oblique oil through of oil outlet, helical oil groove, oblique oil through oil outlet and go out oil groove; During crankshaft rotating; Refrigerant vapor in the refrigerator oil can be from rod radial air vent be directly discharged, and the intensity of the eccentric shaft of bent axle has not only been satisfied in this kind design; But also each component that make refrigeration compressor have all obtained good lubricating, and have reduced the wearing and tearing power consumption and the COP of refrigeration compressor.
