Abstract
The utility model relates to a single crank multiple range flexible beam-pumping unit cantilever shaft fixed pulley, aiming at solving problems of complex structure and low effective load of existing single crank multiple range beam-pumping fixed pulley. The utility model is characterized in that: a shaft sleeve (2), with a built-in cantilever shaft (4), is fixed on a frame (1); the back end of the cantilever shaft (4) is connected with a dorsal cap (6) through screw-threaded joint, while the front end is clipped out of the shaft sleeve (2) through a stage; on the stage of the cantilever shaft (4) out of the shaft sleeve (2) is connected with a fixed pulley (7); a bearing (8) is fixed on the stage of the cantilever shaft (4) inside the stage hole of the fixed pulley (7); the outer end face of the fixed pulley (7) is connected with a gland (9) through a bolt. The utility model has the advantage of simple structure and high effective load.
Description
Technical field:
The utility model relates to the used transmission device of pumping unit, especially single-crank multiple-stroke flexible type pumping unit cantilevered axle static pulley in the oil recovery field, oil field.
Background technique:
Along with Oilfield developing, technology constantly develops, mechanical oil recovery equip ment from the beam pumping unit to the submersible electric pump, screw pump etc., of a great variety, to adapt to the needs of different productive lives.At present, advantage such as stripper well adopts single-crank multiple-stroke pumping unit lifting well liquid, and is low because of its power consumption, and one-time investment is little is well received.But the static pulley of deciding on its support exists complex structure because of reasons in structure, and useful load is low, and manufacturing and installation difficulty is unfavorable for applying.
The model utility content:
In order to solve existing single-crank multiple-stroke pumping unit static pulley complex structure and the low problem of useful load, the utility model provides a kind of single-crank multiple-stroke flexible type pumping unit cantilevered axle static pulley, and this single-crank multiple-stroke flexible type pumping unit cantilevered axle static pulley has characteristics simple in structure and that useful load is high.
The technical solution of the utility model is: this single-crank multiple-stroke flexible type pumping unit cantilevered axle static pulley comprises support, be fixed with axle sleeve on the support, axle sleeve is built-in with cantilevered axle, is with packing ring under the step of cantilevered axle rear end, on the outer cantilevered axle of packing ring by the back of the body cap that has been threaded; The cantilevered axle front end is stuck in outside the axle sleeve by step, is connected with static pulley on the outer cantilevered axle step of axle sleeve, is fixed with bearing on the cantilevered axle step in the static pulley step hole, and static pulley is connected with gland by bolt on the exterior edge face.
Axle sleeve in the such scheme is fixed with stiffening rib down and between support; Stomidium and cantilevered axle contacting point are equipped with seal ring behind the static pulley; Be with packing ring before the step lower back cap of cantilevered axle rear end.
The utlity model has following beneficial effect: this single-crank multiple-stroke flexible type pumping unit cantilevered axle static pulley is owing to take such scheme, makes simple in structurely, and useful load improves, and is easy to manufacture, easy for installation, helps applying.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-support among the figure, the 2-axle sleeve, 3 stiffening ribs, the 4-cantilevered axle, the 5-packing ring, 6-carries on the back cap, 7-static pulley, 8-bearing, 9-gland, 10-seal ring.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this single-crank multiple-stroke flexible type pumping unit cantilevered axle static pulley comprises support 1, be fixed with axle sleeve 2 on the support 1,1 on axle sleeve 2 times and support are fixed with stiffening rib 3, axle sleeve 2 is built-in with cantilevered axle 4, be with packing ring 5 under the cantilevered axle 4 rear end steps, on the packing ring 5 outer cantilevered axle 4 by be threaded the back of the body cap 6; Cantilevered axle 4 front ends are stuck in outside the axle sleeve 2 by step, be connected with static pulley 7 on axle sleeve 2 outer cantilevered axle 4 steps, static pulley 7 back stomidiums and cantilevered axle 4 contacting points are equipped with seal ring 10, be fixed with bearing 8 on cantilevered axle 4 steps in static pulley 7 step holes, static pulley is connected with gland 9 by bolt on 7 exterior edge faces.Owing to adopted such scheme, static pulley to be suspended on to be fixed on the cantilevered axle 4 in support 1 Upper shaft sleeve 2, make simple in structurely, link reduces, easy processing, useful load improves, and is easy for installation, helps applying.
