Description
Technical field
The utility model relates to sliding bearing inspection machine technical field, is specifically related to the high out-degree measurement mechanism of a kind of bearing shell semicircle that internal combustion engine is used.
Background technology
Sliding bearing of the internal-combustion engine mainly comprises bearing shell, lining, flange watt and thrust plate.The main effect of sliding bearing has: 1, bolster and parts on shaft, the running accuracy of retainer shaft; 2, the friction and wear between minimizing rotating shaft and the supporting.The occasion that on high speed, heavy duty, high precision, structure, needs subdivision needs to adopt sliding bearing, like steam turbine, centrifugal compressor, internal combustion engine, large-size machine etc.Therefore sliding bearing is the strength member in the internal combustion engine.
The perfect condition of bearing shell is mounted in the seat hole of internal combustion engine, and outside surface is fitted (like Fig. 1) with the seat hole well, and inside surface and bent axle keep suitable gap.The high out-degree of half peripheral length.Its value can not be excessive or too small, excessively influences the gap of bearing even can cause abnormal distortion; The too small applying degree that can influence bearing shell is unfavorable for the transmission of power and heat.So the processing of bearing shell detects extremely important.Because bearing shell is a kind of split type structure, its straight can't measurement can only replace the check of semicircle girth.The high out-degree of the semicircle of bearing shell (being commonly called as the radius height) is too little, and then bearing shell is installed back " falling into " and is present (like Fig. 2) in hole, in " room " part.In internal combustion engine, the room can be full of by lubricated oil.Influence the distribution of oil film pressure on the one hand, can directly damage a hole on the other hand, cause serious consequence.If the high out-degree of semicircle too big (like Fig. 3) then can cause the upper and lower seat hole of bent axle to be adjacent to effectively, not only bearing shell is easy to damage (unbalance stress, heat-sinking capability poor), also can cause serious disastrous effect.
Because oil pressure control system is often found to reveal, and causes the sanitation and hygiene of working site very poor, even and air pressure breaks down, can not cause greasy dirt etc., on-the-spot cleaning is greatly improved.
The high out-degree of semicircle for bearing shell is measured, and needs specialized apparatus.Because industry is professional extremely strong and industry is less relatively, this kind equipment generally is that producer self buys relevant part, processes the back assembling.So can only satisfy basic demand, precision is not high enough; And the control of great majority employing oil pressure, find oily leakage problem through regular meeting, cause the sanitation and hygiene of working site very poor.
Summary of the invention
The basic task of the utility model is to overcome the problem that prior art exists, and provides a kind of measuring accuracy high, sanitation and hygiene, the high out-degree measurement mechanism of bearing shell semicircle easy to maintenance.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the high out-degree measurement mechanism of a kind of bearing shell semicircle, comprise the standard mold that is fixed on the work top, and the standard mold is provided with semi-circular recesses; On semi-circular recesses one side, be provided with the level pressure piece; Semi-circular recesses opposite side top is provided with the mold briquetting, and the mold briquetting is provided with a meter, it is characterized in that: said mold briquetting is driven by a cylinder driver; Cylinder driver comprises cylinder; On cylinder, be provided with the pressure output shaft, cylinder is connected with source of the gas, and the pressure output shaft of cylinder is connected with the mold briquetting; Be provided with pressure regulator valve between source of the gas and the cylinder, pressure regulator valve is provided with overflow ducts.
On the pressure output shaft of said cylinder pressure transducer is installed, pressure transducer and shows that the display screen of the pressure of mold briquetting is connected.
Be provided with rain glass between said pressure regulator valve and the source of the gas.
The beneficial effect of the utility model is:
Because to survey the reason device be the pressure of measuring briquetting, be not measure briquetting stressed in the utility model, and display screen directly shows the pressure of mold briquetting, promptly pressure can directly show, rather than calculates indirectly, so degree of accuracy is high.
More particularly: 1, measure accurately: the pressure control of cylinder adopts precise sensors, and its error is≤0.05%, improves greatly than the error (>=5%) of oil pressure gauge.
2, digital display: the pressure of cylinder can directly show, adopts oil pressure gauge error >=5% than traditional structure, and precision improves.
3, cleaning: because oil pressure control system is often found to reveal, cause the sanitation and hygiene of working site very poor, even and air pressure breaks down, can not cause greasy dirt etc., on-the-spot cleaning is greatly improved.
4, easy to maintenance: because oil ratio gas is difficult to sealing, the maintenance of equipment is convenient.
As shown in table 1, the performance comparison of the utility model and prior art comparative example is following:
| ? | The present invention | Comparative example |
| Accuracy of measurement | ≤0.05% | ≥5% |
| Cleanliness | Good | Difference |
| Pressure display | Numeral shows | Do not have |
| Safeguard | Be prone to | Difficult |
In a word, the utlity model has simple to operate, applicability is strong, degree of accuracy is high, be prone to cleaning and advantage easy to maintenance, can make things convenient for the high out-degree of the semicircle of accurately measuring bearing shell.
