The utility model is realized by following technical measures: it comprises crankcase, bent axle is installed in the crankcase, fore bearing end cap and rear bearing end cap are installed between crankshaft two end and the crankcase, the inside of crankshaft rear end is provided with oil inlet hole, on the bent axle along radially being provided with the oil outlet that at least one communicates with oil inlet hole, oil outlet communicates with pressure oil chamber, and pressure oil chamber is communicated with the import of crankshaft oil hole, and the outlet of crankshaft oil hole is corresponding with the crankshaft journal position; The oil inlet hole of crankshaft rear end is communicated with independent external lubricating oil tank by oil pipe, and lubricating oil tank is connected with the bottom of crankcase by return tube.Oil inlet hole, the oil outlet that communicates with oil inlet hole and pressure oil chamber that the inside of the crankshaft rear end in the utility model is provided with have constituted centrifugal pump, this pump is not subjected to the restriction of sense of rotation, it sucks lubricant oil from lubricating oil tank, enter crankshaft oil hole, thereby lubricated the axle journal of bent axle, lubricant oil from rubbing surface flows out is splashed to other parts again, has guaranteed lubricated formedness.
The annular groove of above-mentioned pressure oil chamber on the bent axle of crankshaft rear end bearing bore diameter corresponding part, being provided with.This processing simple in structure, easy, can reduce production costs.
The oil outlet that the above-mentioned oil inlet hole with crankshaft rear end inside is communicated with specifically can adopt three, can fully satisfy lubricated needs like this, guarantees the oil mass of pressure oil chamber.
In above-mentioned rear bearing end cap, be provided with seal ring between bearing and the bent axle.Can prevent effectively that like this lubricant oil is excessive from pressure oil chamber, make pressure oil all flow to crankshaft journal as far as possible from crankshaft oil hole.
The beneficial effect of this programme can be learnt according to the narration to such scheme, the technological scheme of encircling the lubricated braking usefulness air compressor of oil pressure certainly that its structure is simpler, manufacture cost is lower, this scheme does not need the engine lube system fuel feeding equally, so it is lubricated reliable, prolonged the working life of air compressor, also reduced simultaneously the consumption of lubricant oil, also avoided air compressor because of lacking the damage that lubricant oil causes; And it adopts the oily mode of sending of centrifugal pump formula, so it is not subjected to the restriction of sense of rotation, so it can significantly reduce the kind of bent axle, increases its versatility, simplifies manufacturing procedure, makes production process more convenient, has reduced cost of production.

Embodiment
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by an embodiment.
As shown in Figure 1, the utility model is a kind of from encircling the lubricated braking air compressor of oil pressure, it comprises crankcase 5, bent axle 3 is installed in the crankcase 5, fore bearing end cap 21 and rear bearing end cap 20 are installed between bent axle 3 two ends and the crankcase 5, oilhole 4 places in the rear bearing end cap 20 on the corresponding bent axle 3 are provided with pressure oil chamber 6, and seal ring 8 is installed in the rear bearing end cap 20, and sealing circle 8 is installed between bearing 24 and the bent axle 3.The inside of bent axle 3 rear ends is provided with oil inlet hole 10, oil inlet hole 10 by oil-feed take over 11 and oil pipe 19 is communicated with independent external lubricating oil tank 13, lubricating oil tank 13 passes through return tube 12 and return tube adapter 7 and is connected with the bottom of crankcase 5; On the bent axle 3 along radially being provided with the oil outlet 9 that at least one communicates with oil inlet hole 10, specifically can adopt three oil outlets 9, oil outlet 9 communicates with pressure oil chamber 6, and pressure oil chamber 6 is communicated with (see figure 2) with the import of crankshaft oil hole 4, and the outlet of crankshaft oil hole 4 is corresponding with the crankshaft journal position.Wherein pressure oil chamber 6 is the annular groove that is provided with on the bent axle of bent axle 3 rear end bearings 24 internal diameter corresponding parts.
Lubricating oil tank 13 loam cakes are provided with oil filler 23, and oil filler 23 sidewalls are provided with the relief opening 14 that communicates with atmosphere, oil filler 23 inner caps 16 that are provided with suitable for reading, and inner cap 16 is provided with exhaust port 15, the top enclosing cover 17 that also is equipped with of inner cap 16.The top of lubricating oil tank 13 also is provided with the support 18 that can be connected with the air compressor housing.
During work, bent axle 3 rotations, lubricant oil flow into oil inlet hole 10 from lubricating oil tank 13, under action of centrifugal force, lubricant oil throws away in the groove 6 from oil outlet 9, because groove 6 forms pressure oil chamber with bearing bore diameter, and the lubricant oil of certain pressure has been arranged, Via shafting oil hole 4 is to crankshaft journal, thereby lubricated the axle journal of bent axle 3, lubricant oil from rubbing surface flows out is splashed to other parts again, has guaranteed lubricated formedness.Move up and down with piston 1, can form respiration in crankcase 5, respiration is got back to lubricating oil tank 13 with lubricant oil through return tube 12, thereby finishes the self-loopa of lubricant oil.The gas of breathing communicates with atmosphere through exhaust port 15 on lubricating oil tank 13 inner caps 16 and the relief opening 14 on oil filler 23 sidewalls.It can play the effect of the resuscitation apparatus of existing air compressor, because the volume of the volume ratio resuscitation apparatus of lubricating oil tank 13 is big, effect of settling to the lubricant oil of scurrying out along with air is better, and it not only can replace original resuscitation apparatus, and than original resuscitation apparatus better effects if.
