Abstract
The utility model relates to a direction reverser for chain oil sucker, and the utility model has four corners respectively provided with wheel round-trip racks of guiding wheels. The utility model is characterized in that revolving shafts with rotating arms at one end are installed at the middles of the round-trip racks, and the ends of the rotating arms are hinged with main driving chains of a pumping unit. The reversing mechanism has the advantages of steady and free reversing direction, small impact of chains, simple structure and low costs.
Description
The utility model relates to petroleum production machinery, is specially a kind of changement on the chain drive pumping unit.
The pumping unit of the employing chain type transmission of existing public use, its changement is separately installed with the round frame of upper saw pulley by four bights, and crosswise fixed is coming and going two slide bars and the slide block that can horizontally slip along two slide bars by slide opening on the frame and is being installed in the slide block center and constitutes with turning axle that the main transmission chain links together.The reversing principle of this changement is when making progress (or the downwards) upper sprocket wheel of walking (or lower sprocket) position when the main transmission chain drives whole changement, chain by turning axle drive slide block to the right (or left) slide, finish coming and going the move up and down commutation of direction of frame.In use there are three shortcomings in this changement: the one, when commutation,, chain is caused great impact because slide block laterally slides fast, and produce judder, both quickened the fatigue damage of chain, influence the stable of complete machine performance again; The 2nd, the slide block slide opening is when slide bar slides, because radial force makes frictional force bigger, often because of insufficient lubrication takes place stuckly not slide, causes the malfunctioning accident of changement; The 3rd, this changement is owing to the structure more complicated, and requirement on machining accuracy is higher, makes manufacture cost corresponding higher.
The purpose of this utility model is to provide a kind of and when commutation chain is impacted little, the difficult malfunctioning accident of commutation that takes place, and is simple in structure, the changement of low cost of manufacture.
Technical solution of the present utility model is, cancels the slide bar and the slide block of above-mentioned existing changement, only in the center that comes and goes frame the turning axle that one end has pivoted arm is installed, and the end and the chain of pivoted arm are hinged.
The changement that adopts technique scheme to manufacture, when chain by pivoted arm and turning axle, when the round frame of drive moves to upper sprocket wheel or lower sprocket position up or down, pivoted arm turns over 180 degree with the chain of motion gradually from transverse state around the axle center, realize coming and going the mild commutation of frame motion, can not produce big impact to chain, vibration noise obviously reduces; This changement only by the pivoted arm Rotation With Changing to, the malfunctioning accident of commutation be difficult for to take place in commutation balance of movement freely; Because simple in structure, parts are few, manufacture cost only is about 1/4th of an existing changement.
Accompanying drawing is a structural representation of the present utility model, and wherein Fig. 1 is the side view that comprises the changement of chain wheel, and Fig. 2 does not comprise that for Fig. 1 the K of sprocket wheel is to view.
In conjunction with Fig. 1 and Fig. 2, the round frame (2) of this changement is square, stiffening rib with six symmetrical distributions, its four bights are separately installed with upper saw pulley (1), the center is equipped with turning axle (8) by bearing (6,7) and spacer (9), one end of turning axle (8) has pivoted arm (5), and the end of pivoted arm (5) is by bearing pin (4) and hinged by the chain of sprocket wheel (3) transmission.
Claims (1)
1, a kind of chain drive pumping unit changement, there are four bights that the round frame (2) of upper saw pulley (1) is installed respectively, it is characterized in that the turning axle (8) that an end has pivoted arm (5) is installed in the center of said round frame (2), and the end and the chain of said pivoted arm are hinged.
