Abstract
The invention belongs to the technical field of the fully mechanized coal mining equipment and relates to an improved mining plunger pump, namely a mining plunger pump driven by a herringbone gear bank. The mining plunger pump driven by the herringbone gear bank comprises a box, a crank, a connecting rod, a slider, a plunger assembly, a valve body assembly and a gear drive pair; a cylinder sleeve, a cylinder sleeve sealing assembly, a liquid inlet valve assembly and a drain valve assembly are mounted in the valve body assembly; the mining plunger pump is characterized in that the gear drive pair is of a herringbone gear bank drive structure which is composed of two helical gears which are the same in helical angle and opposite in direction. The herringbone gear drive of the mining plunger pump has various advantages of helical gear drive, and the shortcoming of large axial force generated by helical gear drive is also overcome. Compared with a straight gear and a helical gear, the manufacturing requirements of the herringbone gear are higher. The mining plunger pump driven by the herringbone gear bank is applicable to horizontal three-cylinder emulsion pumps and atomizing pumps, and also to horizontal five-cylinder emulsion pumps and atomizing pumps.
Description
Technical field
The invention belongs to mining
combine and adoptequipment technical field, relates to a kind of improved mining plunger pump, the i.e. gear-driven mining plunger pump of lineup's word.
Background technique
Mining plunger pump comprises emulsion pump for coal mine and atomizing pump.Emulsion pump is the necessary equipment of colliery fully-mechanized coalface, is the power source of working surface hydraulic support.Atomizing pump is also the necessary equipment of colliery fully-mechanized coalface, is supporting for working surface coal mining machine, plays the effect that reduces and control face dust concentration, cooling coal winning machine and working surface fire-fighting.Mining plunger pump adopts the general structure of horizontal three cylinders or horizontal five cylinders, through primary cylinder gear transmission, with the motion of the parts such as dynamic crankshaft, connecting rod, slide block, plunger, mechanical energy is converted into hydraulic energy.
The application of mining plunger pump comes from the eighties of last century western countries such as Britain, Germany of the fifties, and China starts import application the seventies in eighties of last century, and has progressively realized production domesticization.Early stage mining plunger pump, because transmission power is not very large, all adopts straight toothed spur gear structure both at home and abroad.Along with increasing substantially of coal mine work area mining rate and efficiency, the power of mining plunger pump also has increased significantly, and has brought up to hundreds of kilowatt from tens kilowatts.In order to reduce noise and the vibration of straight toothed spur gear, a lot of producers both domestic and external have all adopted the structure of helical gear, are used for improving gear-driven ability.Helical gear have larger bearing capacity than straight toothed spur gear, turn round more steady, and noise is less.
When the shortcoming of helical gear is work, can under the effect of working load radially, derive a larger axial force, need to use thrust-bearing, make structure become complicated.In the time that bent axle does uniform circular motion, the point-to-point speed of plunger is the Changing Pattern of obeying sine function, and the radially working load that makes mining plunger pump is also to change according to the sine function regularity of distribution.The radially working load of this variation also can make the axial force that helical gear derive from occur periodically changing, thereby causes vibration and noise.In the time that the power of mining plunger pump is larger, the negative effect that helical gear bring will be larger.
Summary of the invention
The object of the invention is to propose a kind of mining plunger pump of improved herringbone gear transmission.
The present invention is achieved in that the gear-driven mining plunger pump of lineup's word, comprise casing, bent axle, connecting rod, slide block, plunger assembly, valve component and gear driving pair, cylinder sleeve, liner packing assembly, liquid feed valve assembly, liquid discharging valve assembly are installed in valve component, it is characterized in that described gear driving pair adopts lineup's word gear transmission structure, described herringbone gear drive mechanism is formed by the helical gear combination of two helix angle equal and opposite in directions, opposite direction.
Mining plunger pump of the present invention, by the secondary motion of motor driven gear, changes the straight reciprocating motion of plunger through linkage rod slide block mechanism into rotatablely moving, and by the plunger suction to liquid and extrusion in cylinder sleeve, realizes and changes mechanical energy into hydraulic energy.
The helical gear merging that drive mechanism of the present invention is equivalent to two helix angle equal and opposite in directions, opposite direction forms, and the axial force that these two helical gears derive from the time of work is also equal and opposite in direction, opposite direction.
Herringbone gear transmission of the present invention not only possesses helical gear every advantage, has also overcome Helical gear Transmission and can produce the shortcoming of larger axis to power.For spur gear and helical gear, the manufacture of herringbone gear requires higher.But due to popularizing of CNC processing technology and machining center equipment, the requirement of manufacture view has not been problem.
The present invention is applicable to emulsion pump and the atomizing pump of horizontal three cylinders, is also applicable to emulsion pump and the atomizing pump of horizontal five cylinders.
Brief description of the drawings

Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail.
Embodiment: the mining plunger pump of the present embodiment lineup word drive mechanism is emulsion pump, its structure as shown in drawings, mainly comprise casing 1, bent axle 2, connecting rod, slide block, plunger assembly 3, valve component 4 and gear driving pair 5, its main feature is that gear driving pair 5 adopts lineup's word gear transmission structure, described herringbone gear drive mechanism is formed by the helical gear combination of two helix angle equal and opposite in directions, opposite direction, i.e. double helical spurgear transmission.
The helical gear merging that embodiment's drive mechanism is equivalent to two helix angle equal and opposite in directions, opposite direction forms, and the axial force that these two helical gears derive from the time of work is also equal and opposite in direction, opposite direction.Therefore, not only possess helical gear every advantage, also overcome Helical gear Transmission and can produce the shortcoming of larger axis to power.
The known cylinder sleeve in this field, liner packing assembly, liquid feed valve assembly, liquid discharging valve assembly etc. are installed in the valve component 4 described in embodiment.By the secondary motion of motor driven gear, change the straight reciprocating motion of plunger through linkage rod slide block mechanism into rotatablely moving, by the plunger suction to liquid and extrusion in cylinder sleeve, realize and change mechanical energy into hydraulic energy.
