Description
Technical field
The utility model relates to a kind of air compressor.
Background technique
At present, in air compressor field, design comparison gear-box and oil pump become one is few, its reason be mainly the gear-box of integrated oil pump due to oil-absorbing pipeline longer, when moulding by casting, require that corresponding core length is also long.And for long core, in pouring technology process, can exist because length is long, core is not easy to fix, casting finished products thickness is not easy the problems such as guarantee.In addition, long core can be inadequate because of bonding strength, produces loose sand during cast, and then cause the problems such as finished product cast scab to produce.Generally speaking, gear-box and the maximum drawback of oil pump unitary design are that foundry goods scrappage is high, improve cost of production.
For this problem, a kind of new air compressor tool is provided to be of great significance.
Model utility content
For solving the problem, the utility model provides a kind of air compressor, and it is convenient to the coaxial rotation realizing gear-box and oil pump, ensures yield rate.
For achieving the above object, air compressor of the present utility model, comprise gear-box and the oil pump coaxial with described gear-box, described gear-box and described oil pump are driven by drive unit and together rotate, described gear-box is provided with the fuel sucking pipe be connected with the inlet port of described oil pump, described fuel sucking pipe is threaded connection part and is fixed on the housing of described gear-box.
Preferably, described fuel sucking pipe has a folded end, and described folded end and described gear-box transition fit, be provided with seal ring between described folded end and described gear-box.
Preferably, described fuel sucking pipe is stainless-steel pipe.
Preferably, described fuel sucking pipe is welded with bending plate, described housing is provided with contiguous block, described threaded connector is fastening screw trip bolt, and described fastening screw trip bolt is through described bending plate and described contiguous block and be fixed on described housing by described fuel sucking pipe.
Preferably, described contiguous block is cylindric.
Preferably, described drive unit is motor.
Air compressor of the present utility model, by gear-box and oil pump integrated, and the fuel sucking pipe of oil pump is arranged separately, is threaded connection part and is fixedly connected with gear-box, this structure, without the need to casting fuel sucking pipe, thus can ensure yield rate.In addition, fuel sucking pipe of the present utility model, is convenient to mounting or dismounting.

Embodiment
Below, by reference to the accompanying drawings, structure of the present utility model and working principle etc. are further described.
See Fig. 1-Fig. 6, air compressor of the present utility model, comprises gear-box 1 and the oil pump 7 coaxial with gear-box 1, and namely gear-box 1 and oil pump 7 have common live axle 8, this live axle 8 is fixedly linked with drive unit, and gear-box 1 and oil pump 7 are driven by drive unit and together rotate.Particularly, this drive unit can be chosen as motor.
Gear-box 1 is provided with the fuel sucking pipe 2 be connected with the inlet port of oil pump 7, this fuel sucking pipe 2 one end can be connected with fuel tank, and the other end is connected with the inlet port of oil pump 7, so that oil pump 7 can by this fuel sucking pipe 2 by the oily sucking-off in fuel tank.Certainly, can arrange passage in gear-box 1 inside, fuel sucking pipe 2 is connected with this passage, and this passage leads to the inlet port of oil pump 7.In the utility model, fuel sucking pipe 2 is threaded connection part and is fixed on the housing of gear-box 1.This mode, without the need to processing fuel sucking pipe 2 by the mode of casting, only need an external fuel sucking pipe 2, this structure of the present utility model, can improve the yield rate of product greatly.
As a kind of mode, in the utility model, fuel sucking pipe 2 has a folded end 201, and folded end 201 and gear-box 1 transition fit, be provided with seal ring 6 between folded end 201 and gear-box 1.When carrying out oil suction under the driving of oil pump 7 at drive unit, sealing circle 6 can ensure good sealability, and fluid is sucked smoothly by oil pump 7, afterwards, is supplied need the parts of lubrication to lubricate by this oil pump 7.
In the utility model, fuel sucking pipe 2 can be chosen as various material, and be preferably stainless-steel pipe, it can ensure good intensity, and easy to use.
Particularly, in the utility model, fuel sucking pipe 2 adopts such fixed structure, as shown in FIG., fuel sucking pipe 2 is welded with bending plate 4, housing is provided with contiguous block 3, threaded connector is fastening screw trip bolt 5, and fastening screw trip bolt 5 is through bending plate 4 and contiguous block 3 and be fixed on housing by fuel sucking pipe 2.This mode, structure is simple, is convenient to the fixed disassembly of fuel sucking pipe 2.
The shape of contiguous block 3 can make all more options, and such as, in the utility model, contiguous block 3 is cylindric.This contiguous block 3 is fixed on the housing of gear-box 1, and bending plate 4 is constructed to L shape, and an one edge is welded on fuel sucking pipe 2, and another edge is fixed on contiguous block 3 by fastening screw trip bolt 5, thus fuel sucking pipe 2 is fixed on the housing of gear-box 1 securely.
During use, fuel sucking pipe 2 is inserted in the mounting hole (not indicating in figure) of gear-box 1, fixed by fastening screw trip bolt 5.Starting electrical machinery, the live axle 8 of motor rotates, and gear-box 1 and oil pump 7 synchronous axial system (are specially the inner rotation part of the two, such as gear etc.), fluid enters into oil pump 7 by fuel tank through fuel sucking pipe 2 under the active force of oil pump 7, afterwards, exports parts to be lubricated to.When fuel sucking pipe 2 changed by needs, screwing off fastening screw trip bolt 5 can be dismantled, the fuel sucking pipe 2 more renewed.
This air compressor of the present utility model, gear-box 1 and oil pump 7 are coaxially arranged, and the technique that fuel sucking pipe 2 is cast for non-Unitary, oil pump 7 is connected with the fuel tank having fluid by the fuel sucking pipe 2 arranged separately.This structure of the present utility model, due to without the need to fuel sucking pipe and gear-box together being cast, substantially increases the yield rate of product.
Above, be only schematic description of the present utility model, it will be recognized by those skilled in the art that on the basis of not departing from working principle of the present utility model, can make multiple improvement to the utility model, this all belongs to protection domain of the present utility model.
