In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, upper flange of the present utility model and rotary compressor are further elaborated.Should be appreciated that specific embodiment described herein only for explaining the utility model, and be not used in restriction the utility model.
Embodiment one
Referring to figs. 1 through Fig. 4, the upper flange 100 of the utility model one embodiment, has mounting hole 101, and mounting hole 101 is for holding bent axle, and the inner headed face of mounting hole 101 has along its axially extended screw type finishing bathtray 102.
Wherein, the sectional area of finishing bathtray 102 is determined according to the mounting hole 101 of upper flange, and the sectional area of finishing bathtray 102 is generally 1:110 ~ 1:90 with the section area ratio of mounting hole 101.Preferably, the sectional area of finishing bathtray 102 is 1:100 with the section area ratio of mounting hole 101.The starting point of finishing bathtray 102 becomes the angle of 25 ° ~ 70 ° with the exhaust port of upper flange 100.
Also be provided with oil storage tank 103 at the inner headed face of mounting hole 101, oil storage tank 103 is near the upper-end surface 104 of upper flange 100.Preferably, oil storage tank 103 is circular groove.Wherein, the distance of the upper-end surface 104 of oil storage tank 103 to upper flange 100 is 2mm ~ 5mm.Preferably, the distance of the upper-end surface 104 of oil storage tank 103 to upper flange 100 is 3mm, and when intensity meets the demands, oil storage tank 103 is better the closer to upper-end surface 104.
Upper flange 100 arranges oil storage tank 103, when compressor rotates, enclosure interior lubricant oil rises to oil storage tank 103 from finishing bathtray 102 under pressure, be gathered in oil storage tank 103, under gravity, the lubricant oil in oil storage tank 103 is circulated in housing oil sump (pump housing oil sump) through the inwall of mounting hole 101.
Oil storage tank 103 is set at the inner headed face of upper flange mounting hole 101, adds the waiting time of lubricant oil in upper flange, increase the surface of contact of lubricant oil with bent axle, pump housing lubrication can be improved preferably, pump housing greasy property can be improved.
As a kind of embodiment, the inner headed face of mounting hole 101 is also provided with along its axially extended first oil-return groove 105.Preferably, the diameter of the second oil-return groove 106 is φ 1.5mm ~ φ 3mm, is preferably φ 2mm.Second oil-return groove 105 is set, is convenient to guide long-pending oil in oil storage tank 103 along the second oil-return groove 105 toward dirty, can lubricates the bent axle of compressor better like this.On the inner circumference of mounting hole 101, the angle that the first oil-return groove 105 and finishing bathtray 102 are separated by is less than or equal to 180 °.Preferably, the first oil-return groove 105 and finishing bathtray 102 are oppositely arranged, that is the angle that the first oil-return groove 105 and finishing bathtray 102 are separated by is 180 °.
Wherein, the first oil-return groove 105 can be straight line type oil-return groove, also can be screw type oil-return groove.When the first oil-return groove 105 is screw type oil-return groove, its rotation direction is contrary with the rotation direction of finishing bathtray 102.The long-pending oil be convenient to like this in oil storage tank 103 flows in housing oil sump from the first oil-return groove 105.Long-pending oil in oil storage tank 103 is circulated in housing oil sump through the first oil-return groove 105 under gravity.
Upper flange 100 comprises base, preferably, is also provided with the second oil-return groove 106, second oil-return groove 106 for being communicated with the first oil-return groove 105 also for being communicated with compressor pump oil sump in described base.Namely the first oil-return groove 105 is communicated with the pump housing oil sump of compressor by the second oil-return groove 106.
Lubricant oil is under the High Rotation Speed of bent axle, by the effect of its centrifugal lift, lubricant oil through finishing bathtray 102 gradually by be evacuated in oil storage tank 103, when in oil storage tank 103 oil mass reach a certain amount of time, lubricant oil successively along the first oil-return groove 105 and the second oil-return groove 106, is progressively back in pump housing oil sump under gravity.This kind of mode adds lubricant oil waiting time in upper flange 100, also increase the surface of contact of lubricant oil with bent axle simultaneously, pump housing lubrication can be improved preferably, this upper flange structure defines the oil-way system of " oil sump-finishing bathtray-oil storage tank-oil-return groove-oil sump " a set of self-loopa simultaneously, the time of contact of high-voltage high-speed airflow with lubricant oil can be effectively reduced, thus reduce the oil content of compressor to a certain extent, this upper flange structure can promote pump housing lubrication effect, promotes reliability and the quality of compressor.
