A kind of branched support emulsion pump, including input shaft and bent axle, multiple input gear is provided on input shaft, is provided with and is engaged in the crankshaft toothed wheel of the input gear on bent axle, multiple input axle bearing is provided on input shaft, multiple crankshaft bearings are provided on bent axle.The configuration of the present invention is simple, safe and reliable, noise is small, stable working, and emulsion output quantity is big, can meet the needs of underground majority of case, there is very high promotional value.
Description
Technical field
The present invention relates to a kind of emulsion pump for underground coal mine more particularly to a kind of large spans using multi-point support
Multi-plunger emulsion pump.
Background technology
Emulsion power pack provides hydraulic pressure for working surface hydraulic support and moves as the essential important equipment of fully-mechanized mining working
Power is the heart of entire working face hydraulic system.In recent years, it is increasing with China's high-seam working face, in order to
Meet the high setting load, high working resistance and the demand of fast-moving bracket and safety support of high working face hydraulic support, to hydraulic pressure branch
Frame liquid-supplying system is proposed very high requirement in pressure, flow etc. performance, it is therefore desirable to high-pressure high-flow emulsion pump
Standing, it is mating to carry out.
With the increase of flow, the crankshaft length of emulsion pump is also more also grown.It in rotation, easily deforms, produces
Raw unnecessary noise, so that influencing normal use.
In the prior art, CN105276122A discloses a kind of five-plunger emulsion pump, defeated including input shaft and bent axle
Enter to be provided with even number input helical gear on axis, input helical gear includes left input helical gear and right input helical gear, left input
Helical gear is identical with the right helical gear quantity of input, and input shaft bearing, input shaft bearing to be separately positioned on there are three settings on input shaft
The both ends and centre of input shaft；It is provided with and is engaged in inputting helical gear bent axle helical gear on bent axle, is provided on bent axle
Three crankshaft bearings, crankshaft bearing are separately positioned on the both ends and centre of bent axle.
CN202017590U discloses a kind of three crank throw six plungers face-off formula novel emulsion pump, including mechanical drive department
Point, connecting rod slider component, cover plate assembly, oil groove component, cylinder sleeve component, valve component and pressure controlling section, cooling pipe component,
Shunt tube assemblies and oil pump cover assembly.It is characterized in coaxially being passed through by three groups, with the twin columns being arranged symmetrically on the crank throw of structure type
Plug forms six plungers, and crank throw phase angle is 120 °, has a ram travel to reach extreme value at interval of 60 °.
But above-mentioned multi-plunger emulsion pump is all without disclosing specific supporting way, and its support is unstable, is emulsifying
In the case of liquid pump increased flow capacity, it is difficult to keep the stabilization of work.
Invention content
To solve the above problems, the present invention proposes a kind of branched support emulsion pump, including input shaft and bent axle, the input
Multiple input gear is provided on axis, is provided with and is engaged in the crankshaft toothed wheel of the input gear on the bent axle, it is special
Sign is：More than two bearing of input shaft is provided on the input shaft, more than two bent axle is provided on the bent axle
Bearing.
It is preferred that the bearing of input shaft is no less than 4, the crankshaft bearing is no less than 4.
It is preferred that each input gear and the crankshaft toothed wheel both sides are respectively provided with independent bearing and are supported.
The configuration of the present invention is simple, safe and reliable, noise is small, stable working, and emulsion output quantity is big, can meet underground
The needs of majority of case have very high promotional value.
Description of the drawings
Attached drawing 1 is the structure diagram according to branched support emulsion pump of the present invention.
Specific embodiment
Further exemplary detailed description is done to the present invention below in conjunction with the accompanying drawings.
Referring to attached drawing 1, which depict a preferred embodiment according to branched support emulsion pump of the present invention, difference
There are four bearing of input shaft and four crankshaft bearings for tool.
A kind of branched support emulsion pump including input shaft 1 and bent axle 2, is provided with multiple input gear 3 on input shaft 1, bent
Multiple crankshaft toothed wheels 4 is provided on axis 2, in the present embodiment, two input gears 3 is respectively provided with and crankshaft toothed wheel 4. is defeated
Enter on axis 1 setting there are four bearing of input shaft, there are four crankshaft bearing for setting on bent axle
Four bearing of input shaft are distributed as the main spring bearing 5 in each one of both ends, be mainly used for support input shaft weight and
Two intermediate input shaft central supported bearings 7 are mainly used for improving the rigidity of input shaft, prevent the trembling of input shaft, four
Crankshaft bearing is distributed as the main spring bearing 6 in each one of both ends, is mainly used for supporting the weight of bent axle and two bent axles of centre
Central supported bearing 8.
More spring bearings, i.e. each one of both sides should be set on input shaft, remaining should be set multiple on bent axle in centre
Each one of spring bearing, i.e. both sides ensure that the both sides of each crankshaft toothed wheel are at least each there are one independent crankshaft bearing, while in
Between the setting of bearing of input shaft and crankshaft bearing should also be as avoiding the installation position of gear, in the present embodiment, on input shaft
Setting is again provided with four bearings there are four bearing on bent axle.In addition to two bearings on both sides, two bearings setting in addition
At middle part.The lateral distance of each bearing and gear root should be between 5~20cm, and having between any two bearing should be
More than 10cm.If large-scale emulsion pump, input shaft and bent axle are longer, in order to meet above-mentioned numerical value, can increase bearing
Setting quantity.In this way, on the one hand ensure that the rigidity of input shaft and bent axle, it on the other hand ensure that the support strength of bearing must
It need ensure, there are independent bearings in each gear both sides, that is to say, that in addition to the gear at both ends, each two gear
Between two spring bearings are at least set.It is larger in the flow of pump if only setting a bearing at middle part such as the present invention
In the case of, it would be possible to violent vibration occurs, meanwhile, also it is unfavorable for the investigation of failure and the replacement of part.
The above, the preferable specific embodiment of patent only of the present invention, but the protection domain of patent of the present invention is not
This is confined to, any one skilled in the art can readily occur in the technical scope of patent diselosesll of the present invention
Change or replacement, should all cover within the protection domain of patent of the present invention.
