Description
Technical field
The utility model belongs to the motor speed-changing device field, relates in particular to a kind of pumping-unit motor belt pulley combination gearbox.
Background technique
At present, because the crude oil in the oil reservoir reduces day by day, the oil field has entered the high water-cut development later stage.To guarantee that in development late stage stable production of crude oil mainly relies on the extract mode; In addition, production fluid requirement according to different times, need carry out necessary adjustment to the dynamic parameters of pumping unit, wherein adjust dynamic parameters and comprise that type adjustment, stroke adjustment, jig frequency adjustment and pump directly adjust, the straightforward procedure that extensively adopts is the adjustment to jig frequency; And to the adjustment of jig frequency, mainly is in the past to adjust the motor belt wheel diameter to reach the oil output that improves or reduce oil well, pumping well is operated under the rational state.Because the active time of pumping unit is longer, the corrosion situation of belt pulley is very serious, and dismounting is wasted time and energy very much.The patent No. is ZL95232916.6, and name is called " a kind of formula belt of oil pumping machine wheel easy to assemble "; Application number is 91227362.3, and name is called " suit belt pulley on the pumping well motor "; Application number is ZL99224660.1, and name is called " the box-like belt of oil pumping machine wheel of nested groups "; Application number is ZL99222441.1, the cover that the disclosed technological scheme of utility model patent that name is called " combined type parameter easy adjusting belt of oil pumping machine wheel " only relates to big small belt pulley adds, connect by bolt between it is mutual, mechanical strength is very low, be not suitable for the long-term operation of pumping unit, there is a large amount of potential safety hazards, do not have market so far.Go back some small-sized spline belt pulley in actual applications,, unavoidably stop the program that well is changed belt pulley but keep away though mechanical strength has been arranged.The general oil well that runs well is difficult for Ka Jing (sand card and wax well) and is afraid of to stop most well.Particularly high moisture oil well, the foreign material (sand) in the oil sink fast, and Yi Kajing can cause a large amount of economic losses like this.Some oil well adopts variable-frequency motor, though easy to adjust, cost an arm and a leg, wanting for every has increased cost for oil production about 200,000 yuans greatly.
The model utility content
The utility model is intended to overcome the deficiencies in the prior art part and provides a kind of simple in structure, and is cheap, need not remove stage makeup and costume, and can realize many gear switches, security of operation, pumping-unit motor belt pulley combination gearbox applied widely.
The purpose of this utility model is achieved in that pumping-unit motor belt pulley combination gearbox comprises: casing, fixedly connect gearwheel and middle gear input shaft, be furnished with the splined shaft of spline disjunctor cone pulley, fixedly connect the output shaft of output gear; Described input shaft, splined shaft and output shaft connect through bearing and casing respectively; Described spline disjunctor cone pulley is meshed with output gear and is in engageable position with gearwheel and middle gear; Described spline disjunctor cone pulley can endwisely slip along splined shaft.
As a kind of preferred version, the utility model also can fixedly connect small gear on input shaft; Described small gear and spline disjunctor cone pulley are in engageable position.
The utility model is simple in structure, and is cheap, need not remove stage makeup and costume, and can realize many gear switches, and security of operation is applied widely.The utility model has saved all processes of dismounting belt pulley, has solved belt pulley and has overstock and processing charges.Can be according to how many any speed that change jig frequency of down-hole crude oil and liquid outlet quantity, remarkable in economical benefits.
