Abstract
The utility model is the drive mechanism for a kind of lubricating grease filling pump, drip irrigation device is: the reducing motor of filling pump drives eccentric shaft to rotate, bearing is equipped with in one end of eccentric shaft, bearing outside surface is equipped with crawler shoe, the corresponding oil outlet of each crawler shoe, crawler shoe internal surface contacts with bearing outer ring, the outer surface of crawler shoe has two grooves, low groove is connected with plunger by bearing pin, return ring is enclosed within the upper groove of all crawler shoes, an annular oil-feed tank is had outside the lower dead centre of pump housing plunger, oil pressing plate is equipped with in eccentric shaft upper end, oil-feed tank and eccentric shaft, crawler shoe, plunger and oil pressing plate all the time in accumulator lubricant oil covering under, during filling pump running, eccentric shaft drives crawler shoe, plunger and oil pressing plate make to-and-fro motion in the plunger hole of plunger on the pump housing, complete oil suction, force feed action.
Description
Technical field
The utility model relates to a kind of drive mechanism of lubricating grease auto-grease pump of machinery, and especially this structure can realize porous oiling easily and avoid sucking air initiating failure.
Background technique
At present, known lubricating grease auto-grease pump major part adopts connecting rod, single hole is fuel-displaced, oil separator is utilized to realize porous oiling, also swash plate is utilized to accomplish holes oiling, porous oiling is configured complicated, transmission system all exposes in atmosphere, easily makes system suck air and causes oiling fault.
Summary of the invention
In order to overcome the deficiency that lubricating grease filling pump can not realize porous oiling and easily suck air, the utility model provides a kind of new structure, can realize the porous oiling of filling pump own, and avoids filling pump suction air to cause not fuel-displaced fault.
The technological scheme that the utility model technical solution problem adopts is: on the pump housing, reducing motor drives eccentric shaft to rotate, bearing is equipped with in one end of eccentric shaft, bearing outside surface is equipped with crawler shoe, each crawler shoe fills a plunger, plunger is contained in the plunger hole on the pump housing and slides, each plunger hole is an oil outlet, crawler shoe internal surface contacts with bearing outside surface, the outer surface of crawler shoe has two grooves, low groove is connected with plunger by bearing pin, return ring is enclosed within the upper groove of all crawler shoes, an annular oil-feed tank is cut outside the lower dead centre of pump housing plunger, eccentric shaft end face is equipped with the oil pressing plate that two ends have angle excursion.Annular oil-feed tank and eccentric shaft, bearing, crawler shoe, plunger and oil pressing plate are covered by lubricating grease in accumulator all the time, during running, crawler shoe has a small amount of relative sliding at bearing outside surface, during filling pump work, lubricating grease is pressed into annular oil-feed tank by oil pressing plate, when plunger exits, lubricating grease is sucked in plunger hole, oil pressing plate can also stir accumulator lubricating grease simultaneously, avoid thin oil in lubricating grease to separate out, this drive mechanism realizes porous oiling and avoids sucking the object of air.
The beneficial effects of the utility model are, during oiling, eccentric shaft is by bearing, crawler shoe, the oiling of promotion plunger, and plunger retracts by return ring by plunger return, and drive system structure is simple, easily realizes porous oiling; Whole transmission system, all under the covering of accumulator lubricating grease, can not suck air, avoids breaking down because sucking air; And to moving element, there is good lubrication, reduce fault, life-saving; During work, the lubricating grease of oil pressing plate stirring accumulator avoids thin oil to separate out.
