The oil leak of pumping unit speed reduction box problem is very general and be difficult to solve in field produces, brings very big difficulty for oil well management and production, and keeps the safety in production to oil well and to cause a lot of potential safety hazards.It is reported that the oil leak of pumping unit speed reduction box problem all exists in each field produces, and perplexing the oil recovery workman always.Strengthen, influence oil well production, increase cost of production and cause potential safety hazard and environmental pollution for basic unit's oil well management difficulty.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of existing technology, a kind of oil pumping unit reduction gearbox of anti-leakage of oil to be provided, making it oil-proof.
The purpose of the utility model is achieved in that a kind of oil pumping unit reduction gearbox of anti-leakage of oil, comprises casing, places input shaft and output shaft in the casing; Clutch shaft bearing is set on the input shaft; First cavity is set between clutch shaft bearing and the casing, the one or three oil canal is set in the casing, first hydraulic fluid port of the one or three oil canal is connected with cabinets cavity; Second hydraulic fluid port of the one or three oil canal is connected with first cavity; The 3rd hydraulic fluid port internal thread of the one or three oil canal connects first plug, on the input shaft outside the said casing input shaft cover plate is set, and the input shaft cover plate is connected with casing; Second bearing is set on the said output shaft; Second cavity is set between second bearing and the casing, two the two or three oil canals are set in the casing, first hydraulic fluid port of each the two or three oil canal is connected with cabinets cavity respectively; Second hydraulic fluid port of each the two or three oil canal is connected with second cavity respectively; The 3rd hydraulic fluid port of each the two or three oil canal internal thread respectively connects second plug, on the output shaft outside the said casing output shaft cover plate is set, and the output shaft cover plate is connected with casing; On the input shaft cover plate of the said first plug corresponding part first through hole is set axially, the diameter of first through hole is provided with two-lip seal greater than the diameter of first plug between input shaft cover plate and the input shaft; Second through hole axially is set respectively on the output shaft cover plate of said each second plug corresponding part, and the diameter of second through hole is provided with double-deck fine and close oil sealing greater than the diameter of second plug between output shaft cover plate and the output shaft.
The utility model is through above design, in the input shaft part, after lubricant oil is lubricated clutch shaft bearing; Flow of lubricant, need not be pulled down the input shaft cover plate when oil circuit stops up to the one or three oil canal; Can stretch in first through hole through instrument first plug is taken off, carry out the high pressure mediation.And because two-lip seal is installed, and good sealing effect between input shaft and the input shaft cover plate, lubricant oil can not spill from here.Output shaft partly adopts same quadrat method.
The improvement method that the utility model adopts " stifled, thin " to combine; The speed reducer maintenance is become the regular maintenance content by loaded down with trivial details, complicated, difficult work; The oil leak of pumping unit speed reduction box fault is administered in regular maintenance, oil accident hidden danger is handled in bud.Improve the pumping unit managerial skills, eliminate pumping unit safety and environmental pollution hidden danger, alleviate labor strength, practice thrift cost.
