Abstract
An axial type electric grease lubricating pump comprises a motor speed reducer, a pump body and a spindle. One or a plurality of plungers axially distributed is arranged on the pump body, the spindleis equipped with a planar cam and an intermittent gear, the upper portion of each plunger hole of the pump body is equipped with a rotary valve which is in meshing transmission with the intermittent gear, and the meshing transmission position of the intermittent gear and each rotary valve corresponds to the mounting position of the planar cam. The motor speed reducer drives the spindle, axially drives the plungers to move alternately through the planar cam, simultaneously drives the rotary valves via the intermittent gear, and enables the rotary valves to be communicated with oil suction openings and oil discharge openings at corresponding positions, thereby completing oil suction and oil discharge processes. After utilizing the technical scheme, the lubricating pump not only can be adaptable to high consistency grease, but also can increase reliability.
Description
Technical field
The utility model relates to the electronic grease lubrication pump of a kind of axial type, belongs to the function basic part in the lubrication technical field.
Background technique
In the grease centralized lubrication system, its pumping source generally all adopts high pressure float amount plunger type lubricant pump at present, and its structural principle substantially roughly the same.Drive eccentric shaft or connecting rod by motor decelerating mechanism, it is reciprocating to drive the plunger of radially arranging, finishes oil suction and oil extraction process.Grease belongs to thickness class material, and flow resistance is big, and also often there is air pocket in inside, makes it the oil-absorbing process difficulty at the plunger type grease pump, and oil-filled characteristic is poor.So existing grease pump all adopts no oil sucting valve structure, promptly offers oil-sucking hole near the pump housing the plunger reverse stroke stop, finishes oil suction, plunger seals oil-sucking hole earlier when forward stroke, begin to compress grease then, discharge by the automatic oil draining valve, to try hard to reduce the oil suction resistance.At present, there is following problem in the known technology that is adopted in the plunger type grease pump, the one, existing no oil sucting valve structural design make plunger in whole oil suction stroke only near stroke stop point with the inlet port conducting, the oil-filled time is very short, grease to low denseness (general cone penetration is greater than 265 1/10mm) can satisfy the oil suction requirement, but for high-consistency (cone penetration is less than 220 1/10mm) grease, then oil-filled characteristic is relatively poor, fatness further raises under the Environmental Conditions of severe cold, even just normally oil extraction.The 2nd, the automatic oil draining valve that is adopted is to utilize pressure reduction principle opening/shutting valve, and is simple in structure, but reliability is relatively poor, and especially when using the high-consistency grease, keying speed slows down, and action is sluggish, causes discharging grease and flows backwards, and reduces oil pump capacity.The 3rd, the crowded oily effect of the crowded oiled-plate method on pump housing top is relatively poor, can not satisfy high-consistency grease oil suction requirement.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of electronic grease lubrication pump of axial type that goes for high-consistency grease medium, to overcome the above-mentioned defective that existing lubricant pump exists.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is: the electronic grease lubrication pump of a kind of axial type, comprise motor reducer, the pump housing, main shaft, the plunger that has one or several to distribute vertically on the described pump housing, dispose face cam and intermittent gear on the described main shaft, the top of each plunger hole of the pump housing disposes the rotary valve with the intermittent gear engagement driving, and the position of intermittent gear and rotary valve engagement driving and the installation position of face cam are corresponding.The motor reducer transmission main shaft, drive plunger is reciprocating vertically by face cam, drives rotary valve through intermittent gear simultaneously, makes it in relevant position and inlet port and oil drain out conducting, finishes oil suction and oil extraction process.
After adopting technique scheme, not only make lubricant pump can adapt to the high-consistency grease, and can effectively improve reliability.
Below in conjunction with drawings and Examples technology contents of the present utility model is described further.

Embodiment
As shown in Figure 1 and Figure 2, the electronic grease lubrication pump of present embodiment axial type comprises motor reducer 1, the pump housing 12, main shaft 2 and oil storage cylinder 10, one group or some groups plungers 4 of symmetric arrangement vertically in the pump housing 12, and configuration one-way valve 14 and safety valve 13, the oil outlet of each plunger 4 can be formed single-point or the fuel-displaced lubricant pump of multiple spot by inner duct merging or fuel-displaced separately in the pump housing 12; Configuration plane cam 3 and intermittent gear 7 on the main shaft 2, the top of each plunger hole of the pump housing 12 disposes the positive drive type rotary valve 5 with intermittent gear 7 engagement driving, and the position of intermittent gear 7 and rotary valve 5 engagement driving and the installation position of face cam 3 are corresponding.Drive main shaft 2 by motor reducer 1, drive face cam 3 rotations, the draw-in groove by plunger 4 ends makes each plunger to-and-fro motion, is contained in the positive drive type rotary valve 5 on each plunger hole top on the intermittent gear 7 transmission pump housings 12 on the main shaft 2.When face cam 3 makes plunger 4 move to upper dead center, the oil extraction stroke finishes, this moment, intermittent gear 7 began engagement with rotary valve 5, rotary valve 5 Rotate 180 degree, the oil-sucking hole of relevant position on its oilhole and the pump housing 12 is communicated with, oil drainage hole sealing simultaneously makes at face cam 3 then that grease enters the plunger vestibule in the descending oil-absorbing process of plunger 4.
Also be provided with in the present embodiment and intermittent gear 7 riveting all-in-one-piece position-arresting disk 8 and block plates 9, its effect is to make rotary valve 5 keep conduction position in oil suction or oil extraction process, prevent the circumferential and axial displacement, to reach in whole oil-absorbing process, oil-sucking hole is in the full open position, guarantee the enough oil-filled time, it is big to adapt to high-consistency grease flow resistance especially, the characteristics that oil-filled process is long; Simultaneously also be unlikely in the oil extraction process, to cause entrap phenomenon.
For overcoming the excessive oil suction resistance of high-consistency grease, eliminate the air pocket that grease inside retains, present embodiment carries out the secondary extruding to the grease that enters the oil suction district, and configuration large helix angle bucket type is squeezed oiled-plate method 11 and spiral oil scraping plate 6 on main shaft 2.The large helix angle bucket type is squeezed oiled-plate method 11 above oil pump oil suction district and with main shaft 2 rotation extruding greases; Spiral oil scraping plate 6 is arranged in the pump housing 12 inlet port places, pushes once more with spiral oil scraping plate 6, by force grease is blown into inlet port, effectively improves the oil absorption of high-consistency grease.
