Description
Technical field
The utility model relates to a kind of oil channel structures, particularly a kind of compressor crank shaft oil channel structures.
Background technique
Compressor in civil area application widely, in refrigeration appliance field as air-conditioning, refrigerator etc. just need to use compressor, adopts the type of cooling of oil cooling usually.Bent axle is the power-transmitting part of compressor, compressor sucks the refrigerant gas of low-temp low-pressure from sucking pipe, motor rotation, through bent axle drivening rod, connecting rod drives the piston in cylinder body to move reciprocatingly again, after compressing, discharges the refrigerant gas of High Temperature High Pressure to outlet pipe to refrigerant gas, for refrigeration cycle provides power, thus realize the refrigeration cycle of compression → condensation (heat release) → expand → evaporate (heat absorption); Oil circuit on bent axle upwards supplies machine oil under the influence of centrifugal force, for friction member provides oiling agent; The design of oil circuit determines the quality that compressor oils; Designing bad oil circuit can cause fuel feeding not smooth, will be stuck between compressor frame and bent axle, causes compressor normally to work.
Bent axle fuel system conventional at present sets up a tail cover (11), this bent axle oils effective, but this mode poor universality is only suitable for compressor use (Fig. 1) that bent axle diameter is greater than 18mm, when bent axle diameter is 14mm or 12mm, aperture under bent axle tail cover (11) is too small, may cause oiling, this design just can not meet usage requirement.Meanwhile, set up tail cover (11) these parts, made the shortcoming that the overall structure poor stability of bent axle, processing and installation are complicated, compressor operating is unstable, overall performance is low, too increase cost of production and production process, for enterprise adds spending.
Model utility content
It is good that technical problem to be solved in the utility model is to provide a kind of versatility, also have when bent axle diameter is less that the effect that well oils, stability are high, processing and install simple, compressor operating stable, overall performance is high, and the crankshaft oilway structure that cost of production is low.
For solving the problems of the technologies described above, the utility model realizes as follows: design a kind of crankshaft oilway structure, is provided with d-axis portion, balance portion and eccentric part from the bottom to top successively; D-axis portion interior lower end is provided with the first oil circuit, and the first oil circuit extends to d-axis portion intermediate portion by d-axis portion bottom opening, is connected with the lower oilhole being located at d-axis portion intermediate portion; Lower oilhole is also connected with the second oil circuit arranged along d-axis portion external peripheral surface spiral; The other end of the second oil circuit is connected with upper oil hole; Upper oil hole is simultaneously by after the conveying oil circuit of inside, balance portion, be communicated with the long-pending oil pocket being arranged on eccentric part inside, long-pending oil pocket side is circular open, and described circular open is arranged on the upper surface of eccentric part, and the center of circle of eccentric part and the center of circle of long-pending oil pocket are for shifting to install; Eccentric part side surface neutral position is also provided with oil outlet, and long-pending oil pocket is connected with oil outlet.
Further, described d-axis subordinate end is also provided with pressure relief vent, and described pressure relief vent is connected with the first oil circuit.
Further, described first oil circuit is skewed design, forms several angle with d-axis portion.
Further, described balance portion is semicircle.
Further, cross section, described balance portion is L shape.
Further, point-blank, eccentric part shifts to install in balance portion at the center in described d-axis portion and balance portion.
Further, described bent axle is ironcasting.
Good effect of the present utility model: in technical solutions of the utility model, traditional tail Analysis of Nested Design is instead of by having offered the first oil circuit on bent axle, make that the bent axle versatility of compressor is good, stability be stronger, processing and install more simple, oil, compressor operating is stablized, improves the overall performance of compressor stability and compressor, and decrease tail cover parts, save spending, reduce being produced into of enterprise.
