Abstract
The utility model relates to a rotary compressor cylinder having a blade groove with a lubricating oil aperture. The utility model comprises a cylinder body, a rotor which is arranged in the cylinder body, a blade groove which is arranged on the cylinder body, and a blade which is arranged in the blade groove and is contacted with the rotor. The utility model is characterized in that the lubricating oil aperture is arranged on the blade groove, and is arranged between an end aperture of the blade groove and a groove opening. Because the utility model is additionally provided with the lubricating oil aperture between the end aperture of the blade groove and the groove opening, the whole blade can be lubricated during the course that the compressor is operated to a lower starting point from an upper starting point, and therefore, the lubricated condition of the blade is improved, the abrasion of the blade during the course of the operation of the compressor is reduced, and the service life is extended.
Description
Technical field
The utility model relates to a kind of compresser cylinder parts, relates in particular to a kind of rotary compressor cylinder of blade troughed belt oilhole.
Background technique
Rotary compressor is in operation process, compressor blade 4 need obtain the lubricated of lubricant oil, see also referring to Fig. 1, shown in Figure 2, the prior art compressor only is provided with a stomidium 5 in the end of blade groove 3, when compressor runs to down the process of initial point from last initial point, lubricant oil is lubricated by 5 pairs of blades 4 of blade groove stomidium, so blade 4 suffered lubricating mainly in the L1 part, and in the L2 of blade part, lubricant oil can only be lubricated it by the gap of spring eye 6 and blade groove 3, therefore lubricating condition is more abominable, this part that causes blade serious wear and quicken to damage in the compressor operation process.
Summary of the invention
The purpose of this utility model is to provide a kind of rotary compressor cylinder of improved blade troughed belt oilhole, it can make the compressor whole blade can both be lubricated in the compressor operation process, thereby reduce the wearing and tearing of blade in the compressor operation process, improve working life.
The purpose of this utility model is achieved in that
A kind of rotary compressor cylinder of blade troughed belt oilhole comprises: cylinder block, be arranged in the rotor of cylinder block, be arranged on the blade groove on the cylinder body, and be arranged in the blade groove and with the contacted blade of rotor; Be characterized in: on described blade groove, be provided with an oilhole.
In the rotary compressor cylinder of above-mentioned blade troughed belt oilhole, wherein, described oilhole is arranged on the A place of blade groove.
In the rotary compressor cylinder of above-mentioned blade troughed belt oilhole, wherein, described oilhole is provided in a side of between blade groove stomidium and the notch.
The rotary compressor cylinder of the utility model blade troughed belt oilhole owing to adopted technique scheme, makes it compared with prior art, has tangible advantage and good effect.The utility model is owing to set up oilhole between cylinder blade groove stomidium and notch, making compressor run to down the process of initial point whole blade from last initial point can both be lubricated, thereby improved the lubricating condition of blade, reduce the wearing and tearing of blade in the compressor operation process, improved working life.
Description of drawings
Embodiment by following rotary compressor cylinder to the utility model blade troughed belt oilhole can further understand the purpose of this utility model, concrete structure characteristics and advantage in conjunction with the description of its accompanying drawing.Wherein, accompanying drawing is:
Fig. 1 is the structural representation of prior art rotary compressor cylinder when the compressor motion is in initial point;
Fig. 2 is the structural representation of prior art rotary compressor cylinder when the compressor motion is in initial point;
Fig. 3 is the structural representation according to the rotary compressor cylinder of the blade troughed belt oilhole that the utility model proposes.
Embodiment
See also shown in Figure 3ly, the rotary compressor cylinder of the utility model blade troughed belt oilhole comprises, cylinder body 1 is arranged in the rotor 2 of cylinder body 1, be arranged on the blade groove 3 on the cylinder body 1 and be arranged in the blade groove 3 and with rotor 2 contacted blades 4; Unlike the prior art be, on blade groove 3, be provided with an oilhole 31, in the present embodiment, this oilhole 31 is arranged on the A place of blade groove 3, promptly is arranged between blade groove 3 stomidiums 5 and the notch 7.Like this, the utility model compresser cylinder is in operation process, when the compressor motion is in initial point, blade groove oilhole 31 is positioned at the bottom of blade, when compressor moves to down initial point, blade groove oilhole 31 is positioned at the middle and upper part of blade, thereby makes the L2 part of blade 4 among Fig. 1 also obtain good lubricating, and has remedied the deficiency that prior art only is lubricated by spring eye 6 and 3 pairs of blades 4 of blade groove.
In sum, the rotary compressor cylinder of the utility model blade troughed belt oilhole is owing to promptly set up an oilhole at the A place of blade groove between blade groove 3 stomidiums 5 and notch 7, make blade lubricating condition be improved significantly, reduced the wearing and tearing of blade in the compressor operation process, therefore very practical.
