Abstract
The utility model relates to a crankshaft, particularly to a crankshaft for a compressor, and belongs to the technical field of compressors. The crankshaft comprises a long shaft body, an eccentric part short shaft body and a balanced block, wherein a first oil way is formed in the inner part of the long shaft body, and a second oil way is formed in the eccentric part short shaft body. The crankshaft is characterized in that slant oil holes are formed in the long shaft body, and communicated with the first oil way; the balanced block is semicircular; a balanced block slant oil hole is formed in the middle position of the balanced block; the number of the slant oil holes is two; one slant oil hole is positioned in the middle of the first oil way, and the other slant oil hole is positioned at the tail end of the first oil way; the crankshaft is made of cast iron. The crankshaft for the compressor is good in universality, compact in structure, good in stability, simple to process and mount and good in oilling amount, enables the running of the compressor to be stable, and improves the stability and the whole performance of the compressor; the balanced block is semicircular, so that the balance performance of the crankshaft is improved.
Description
Technical field
The utility model relates to a kind of bent axle, and particularly a kind of compressor crank shaft, belongs to Compressor Technology field.
Background technique
Bent axle is the power-transmitting part of piston compressor.The extrinsic motives such as motor by bent axle by transmission of power to compressor, and bent axle drives another compressor part---connecting rod mounted thereto, rotation motion is converted into to-and-fro motion, thereby realizes the work of piston compressor.
Existing compressor crankshaft structure is made up of axis body and oil-Absorbing nozzle, oil-Absorbing nozzle is fixed on axis body by riveted joint, oil suction when axis body adjustment rotation, interior refrigerator oil under centrifugal action along upwards fuel feeding of oil circuit, lubricated each friction member, the required precision of its processing and installation is high, and exists oil-Absorbing nozzle because of riveted joint firm dropping not, causes the bent axle bad or faults such as causing the high or card cylinder of compressor horsepower that do not oil that oils.
Model utility content
The purpose of this utility model is: provide a kind of processing that compressor crank shaft simple, reliable performance is installed.
The technical solution of the utility model is:
A kind of compressor crank shaft, comprises major axis body, eccentric part minor axis body and equilibrium block, and there is the first oil circuit described major axis body inside, and described eccentric part minor axis body has the second oil circuit, it is characterized in that: described major axis body is provided with inclined oil hole of air, and inclined oil hole of air communicates with the first oil circuit.
As preferably, described equilibrium block is semicircle.
As preferably, described equilibrium block neutral position is provided with equilibrium block inclined oil hole of air.
As preferably, described inclined oil hole of air has 2.
As preferably, one of described inclined oil hole of air is positioned at the first oil circuit middle part, and another is positioned at the first oil circuit end.
As preferably, the material of described bent axle is cast iron.
The beneficial effects of the utility model are: the utility model arranges inclined oil hole of air at major axis body and replaces traditional oil-Absorbing nozzle, this compressor crank shaft versatility is good, compact structure, good stability, processing and installation are simple, and upper oil mass is good, make compressor operating stable, improve compressor stability, improved compressor overall performance; Equilibrium block is semicircle, has improved the balance quality of bent axle.
Accompanying drawing explanation
Fig. 1 is the plan view of the utility model compressor crank shaft;
Fig. 2 is the plan view of the utility model compressor crank shaft;
Fig. 3 is the right elevation of the utility model compressor crank shaft;
Reference character: 1-major axis body, 2-equilibrium block, 3-eccentric part minor axis body, 4, the first oil circuit, 5-the second oil circuit, 6-inclined oil hole of air, 7-equilibrium block inclined oil hole of air.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As illustrated in figs. 1 and 2, a kind of compressor crank shaft, comprises major axis body 1, eccentric part minor axis body 3 and equilibrium block 2, and there is the first oil circuit 4 major axis body 1 inside, and eccentric part minor axis body 3 has the second oil circuit 5, and major axis body 1 is provided with inclined oil hole of air 6, and inclined oil hole of air 6 communicates with the first oil circuit 1.Inclined oil hole of air 6 has 2, and one is positioned at the first oil circuit 4 middle parts, and another is positioned at the first oil circuit 4 ends.
Fig. 3 is the right elevation of the utility model compressor crank shaft, and equilibrium block 2 is shaped as semicircle, is provided with equilibrium block inclined oil hole of air 7 in equilibrium block 2 neutral positions.The material of compressor crank shaft is cast iron.
The utility model compressor crank shaft is an entirety, oil suction when inclined oil hole of air 6 rotates in axis body adjustment, interior refrigerator oil under centrifugal action along the first oil circuit and the second oil circuit fuel feeding, lubricated each friction member, avoid prior art to exist oil-Absorbing nozzle because of riveted joint firm dropping not, caused the bent axle problem bad or that do not oil that oils; Equilibrium block is semicircle, has improved the balance quality of bent axle in the time that axis body rotates; Bent major and minor axis body structure compactness, good stability, upper oil mass is good, makes compressor operating stable, has improved compressor stability.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
