Description
Technical field
The utility model relates to a kind of oil lubrication structure that is applied to the crankcase of refrigeration compressor.
Background technique
During the refrigeration compressor operation, the refrigeration oil of compressor housing bottom can be by the rotation of bent axle, along bent axle interior oil hole wall, the external helicoid oil groove moves upward, the gap location that a part cooperates with crankcase from bent axle upwards oozes out, another part then passes through bent axle---connecting rod---wrist pin---piston, this two-part oil enters refrigerator system except sub-fraction, sub-fraction is splashed on the housing through bump, all the other most of refrigeration oils will splash into rotor and stator downwards by the Oil Guide through hole of crankcase upper-end surface, finally get back to housing bottom, finish an oil circulation in the compressor.Traditional mentality of designing is directly to open the hole in the crankcase upper end surface, and the position of arranging is arranged on the crankcase upper-end surface mostly, and the shape of arranging and quantity are not unique.By discovering, by improving the oil circuit lubricating structure of crankcase, can improve the circulating load of refrigeration oil in the oil circulation, further stablize the running temperature of key components and parts, can reduce parts depreciation, prolong the compressor life-span.Like this, in the coupling of refrigerator, consumption of compressor is more stable, thereby reduces refrigerator power consumption.Illustrated in figures 1 and 2 is a kind of existing oil lubrication structure that refrigeration compressor is used crankcase, and its oil guiding hole 1 is arranged on the crankcase upper-end surface.The advantage of this kind oil lubrication structure is: oil guiding hole 1 is the one-step casting moulding, and the later stage machining is not had influence.Shortcoming is: the remaining oil mass in crankcase upper-end surface is more, be subjected to the restriction of oil guiding hole position, surface mobility is relatively poor, cause refrigeration oil quantity not sufficient in the actual oil circulation, then need to add refrigeration oil as increasing circulating load, but can improve the compressor cost like this, and the refrigeration oil charging amount too much also may cause bad phenomenon such as compressor oil spout.Simultaneously, refrigeration oil flows downward along oil guiding hole 1, and major part has entered rotor, has weakened the cooling effect (when compressor operating, stator is main heating component) of stator to a certain extent.
Summary of the invention
Technical problem to be solved in the utility model is to propose the compressor of the good cooling results of freezing oil mass abundance, stator in a kind of good fluidity, oil circulation of refrigeration oil with the oil lubrication structure of crankcase.
For solving the problems of the technologies described above, the utility model compressor comprises upper-end surface back-up ring, oil guide slot and lower end surface back-up ring with the oil lubrication structure of crankcase, described upper-end surface back-up ring is located on the upper-end surface of crankcase, described lower end surface back-up ring is located at the outside, lower end surface of crankcase, described upper-end surface back-up ring is provided with out oil groove, described oil guide slot is located on the upper-end surface of crankcase, the outside that goes out oil groove of described upper-end surface back-up ring, and the described inside and outside two ends that go out oil groove join with described oil guide slot and described lower end surface back-up ring respectively.
Above-mentioned compressor is with the oil lubrication structure of crankcase, and described upper-end surface back-up ring is an annulus, and described annulus is provided with two places and states out oil groove, and described oil guide slot and a side described goes out oil groove and join.
The above-mentioned compressor oil lubrication structure of crankcase, the fuel-displaced well width of described upper-end surface back-up ring is identical with the width of described oil guide slot.
The above-mentioned compressor oil lubrication structure of crankcase, described oil guide slot is low inside and high outside skewed slot.
Above-mentioned compressor is with the oil lubrication structure of crankcase, and described lower end surface back-up ring is the step of the certain altitude set up along edge, crankcase lower end surface.
The above-mentioned compressor oil lubrication structure of crankcase, described upper-end surface back-up ring, oil guide slot and lower end surface back-up ring are the one-step casting moulding.
The utility model is owing to adopt said structure, and it has improved the flowability of crankcase surface freezing oil by the upper-end surface back-up ring, makes the refrigeration oil that remains in the surface participate in the oil circulation of whole compressor inside; Further accelerated the flowability of refrigeration oil by oil guide slot, made freezing oil mass abundance in the oil circulation; Make the refrigeration oil major part enter stator by the lower end surface back-up ring, improve the effect of cooling stator, thereby reduced the heat loss of system, make system's operation more stable, and finally realized reducing the effect of refrigerator power consumption, saved the energy.

Embodiment
As shown in Figure 3 and Figure 4, the utility model compressor comprises upper-end surface back-up ring 2, oil guide slot 3 and lower end surface back-up ring 4,5,6,7,8,9 with the oil lubrication structure of crankcase.Upper-end surface back-up ring 2 is located on the upper-end surface of crankcase, and lower end surface back-up ring 4,5,6,7,8,9 is located at the outside, lower end surface of crankcase respectively.Upper-end surface back-up ring 2 is an annulus, is provided with two places at annulus and goes out oil groove.One side of the inner of oil guide slot 3 and upper-end surface back-up ring 2 goes out oil groove joins, and the width that goes out oil groove is identical with the width of oil guide slot 3, and the outer end of oil guide slot 3 is connected with lower end surface back-up ring 8.As Fig. 3 and shown in Figure 5, oil guide slot 3 is skewed slot, and is low inside and high outside, improved the flowability of refrigeration oil.As shown in Figure 4, lower end surface back-up ring 4,5,6,7,8,9 structural design are the steps that increases certain altitude along edge, crankcase lower end surface, make the refrigeration oil that flows down from oil guide slot 3 to drip to the crankcase outside along lower end surface back-up ring 4,5,6,7,8,9.Refrigeration oil is after the central recess place of crankcase upper-end surface amasss completely, two from upper-end surface back-up ring 2 go out the oil groove outflow, a part directly flows to oil guide slot 3, another part finally flows to oil guide slot 3 along the outer wall of upper-end surface back-up ring 2, after refrigeration oil arrives the crankcase lower end surface, outwards drip along lower end surface back-up ring 4,5,6,7,8,9, most refrigeration oils splash in the stator.
Need not to establish the Oil Guide through hole in the utility model structure on the crankcase, it has improved the flowability of crankcase surface freezing oil by the design of upper-end surface back-up ring 2 again, makes the refrigeration oil that remains in the surface participate in the oil circulation of whole compressor inside; By the design of oil guide slot 3, further accelerated the flowability of refrigeration oil; Make the refrigeration oil major part enter stator by lower end surface back-up ring 4,5,6,7,8,9, improve the cooling effect of stator, thereby reduced the heat loss of system, make that system's operation is more stable, and finally realized reducing the effect of refrigerator power consumption, saved the energy.
