Abstract
The utility model relates to a crank pin lubricating device of beam-pumping units, in particular to a crank pin lubricator of a beam-pumping unit. According to the technical scheme, the crank pin lubricator of the beam-pumping unit comprises a circular steel plate, counter bores and a scraping blade, the two counter bores are drilled in the circular steel plate, the two counter bores are matched with two fixing bolts on an inner baffle, and spring cushions are additionally arranged in the two counter bores respectively. The scraping blade is fixedly arranged on the surface of the circular steel plate, and the scraping blade extends out of the outer edge of the inner baffle by 10cm to 20cm. The crank pin lubricator of the beam-pumping unit has the advantages that the scraping blade can paint lubricating grease evenly on a ball bearing, and the lubrication effect is good; in addition, the crank pin lubricator of the beam-pumping unit is simple in structure, convenient to manufacture, obvious in practical effect, low in cost, high in benefit and wide in application range, and can be used for all beam-pumping units.
Description
Technical field
The utility model relates to a kind of lubricating fitting of beam type oil pumping machine crank pin, particularly a kind of beam type oil pumping machine crank pin lubriator.
Background technique
The crank pin of beam pumping unit is the vital part of beam pumping unit, with the bearing transferring power that closely cooperates.Bearing plays a part to support and the fixed crank bearing pin, makes bearing pin realize rotating and control its movement axial and radially, and the working state of bearing directly affects the transmission of crank pin.Lubricated fatigue life and frictions, wearing and tearing, vibration etc. on rolling bearing have important impact, and about 40% damage of bearings is all relevant with insufficient lubrication.Therefore, lubricated is the necessary condition that guarantees that bearing runs well.So the lubrication circumstances of beam type oil pumping machine crank pin bearing also is the problem that the oil recovery worker must pay attention in current check.Through in all previous inspection, opening the pin cover plate finds, the lubricating grease of filling when rotated major part is extruded on the pin cover plate, and on the bearing ball seldom even do not have, cause bearing running hot, retainer or rolling element are out of shape, break, and serious meeting gets loose the crank pin shell, causes beam pumping unit to turn over the machine accident.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of beam type oil pumping machine crank pin lubriator is provided, and what scraping blade can be with lubricating grease uniform spreads upon on the ball bearing high lubricating effect.
Its technological scheme is: comprise round plate, counterbore, scraping blade, described round plate is drilled with two counterbores, and two counterbores match with two fixing bolts on the internal baffle, add respectively spring pad in two counterbores; Fix a scraping blade on the round plate surface, scraping blade stretches out 10-20 centimetre of internal baffle outer.
The beneficial effects of the utility model are: what scraping blade can be with lubricating grease uniform spreads upon on the ball bearing high lubricating effect; In addition, not only simple in structure, easy to make, practical effect is obvious, and cost is low, high efficiency, and applied range, every beam pumping unit all can use.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is side views of the present utility model;
Among the upper figure: round plate 1, counterbore 2, scraping blade 3, spring pad 4.
Embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises round plate 1, counterbore 2, scraping blade 3, described round plate 1 is drilled with two counterbores 2, two counterbores match with two fixing bolts on the internal baffle, two counterbore 2 interior spring pads 4 that add respectively, and making it to be connected with crank pin to prevent that two fixing bolt back-offs from deviating from; Fix a cultrate scraping blade 3 on round plate 1 surface, scraping blade 3 stretches out 10-20 centimetre of internal baffle outer, can fully lubricating grease on the cover plate be scraped, again not scratching machinery position.
After beam pumping unit is used, after opening the pin cover plate, find all to be coated with uniformly and to have spread one deck lubricating grease on the relatively poor bearing ball of lubrication effect in the past, and ball each and every one is complete intact, whole crank pins is lubricated good.
Working principle of the present utility model:
Beam type oil pumping machine crank pin and beam type oil pumping machine crank connect into an integral body by fixing bolt, and when the running of oil pumping oil machine, crank drives the crank pin motion, and bearing and bearing pin closely cooperate, and move with axle.Characteristics according to the crank pin running, beam type oil pumping machine crank pin lubriator is in the beam pumping unit operation process, by being connected to the scraping blade on the crank pin baffle plate, when crank pin bearing and bearing pin motion, with scraping blade the lubricating grease in the crank pin cover plate is scraped, scraping blade gets in the bearing slit part lubricating grease by extruding the lubricating grease in the crank pin cover plate, spread upon uniformly the ball surface, go round and begin again, gradually the lubricating grease in the crank cover plate is scraped into ball bearing inside, reach good lubrication effect, prolonged the working life of bearing.
