Abstract

The utility model relates to an oil pumping machine part, in particular to a pulley assembly. The pulley assembly is characterized by comprising a spindle, a pulley seat, a pulley and a chain link; a spindle hole matched with the spindle is formed on the pulley seat; the pulley seat is sleeved on the spindle; the pulley is rotatably arranged on the pulley seat; and the chain link is fixed on one end of the spindle. The above structure adopts the pulley assembly consisting of the pulley, the pulley seat, the spindle and the chain link, the chain link can be connected with the chain link of an external chain, with the movement of the chain, the chain can be stabilized by means of the guiding of the pulley fixed on the pulley seat, meanwhile, the stable operation of a driving element can be ensured, thereby achieving the purpose of the pulley assembly; and moreover, the pulley assembly is compact in structure and is very simple.

Description

Pulley assembly
Technical field
The utility model relates to a kind of oil pumper parts, especially a kind of pulley assembly.
Background technology
Mechanical block-relief oil production device in the oil well utilizes the periodic elastic deformation of tubing string to produce periodically exactly and pumps, thereby the stratum is produced the piston action of the frequent checker of suction extruding.The machine of kowtowing is that beam pumping unit is traditional pumping unit of oil field extensive use, is directly dragged by ordinary ac asynchronous motor usually.Its crank band drives sucker rod with balance, drives downhole pump the pumping of cycle that fix, and delivers to ground to the oil of down-hole.
Yet the situation of down-hole oil reservoir is complicated especially, but oil pumper in the market, because employing is beam type; A very serious defective is arranged, and it is very short to drive stroke exactly, can only in very short stroke, move, and oil pumping amount once is limited; Efficient is not high, chain type oil pump therefore occurred, and the oil pumper chain drive-belt drives the heavy burden belt movement, in the both sides of oil pumper; Rise on one side, Yi Bian fall, stroke is elongated greatly, thereby has increased the amount of recovering the oil; Chain is when doing annular periodic motion, and small skew can take place actuator when little deviation was arranged, if the structure of double-stranded bar or multichain bar, actuator will fluctuation of service.
Summary of the invention
The purpose of the utility model is, provides a kind of and makes that chain drive is stable, the pulley assembly of compact conformation.
The utility model solves the technical scheme that its technical problem adopted: a kind of pulley assembly; It is characterized in that comprising main shaft, pulley base, pulley, chain link; Pulley base is provided with the axis hole adaptive with main shaft; Pulley base is set on the main shaft, and pulley is arranged on the pulley base rotationally, and chain link is fixed on the end of main shaft.
Further being set to of the utility model: chain link is the U type, on the inwall of chain link, is provided with the connecting hole adaptive with outside chain link plate.
Further being set to of the utility model: on pulley base, be provided with the pulley spindle adaptive with pulley, pulley sleeve is located on the pulley spindle, between pulley and pulley spindle, is provided with bearing.
Said structure adopts a pulley assembly that is made up of pulley, pulley base, main shaft, chain link, and chain link can be connected with the chain link of outside chain, along with chain moves; Dependence is fixed on pulley base top sheave guiding; Stablize chain, guarantee the stable operation of actuator simultaneously, thereby reach the purpose of the utility model; And compact conformation, also fairly simple.
And chain link is the U type; The U die cavity covers on the chain shot of a cable joint, is fixedly connected with chain link through connecting hole then, and pulley assembly just can just can move with chain; Pulley base can circumferentially freely rotate around main shaft; And pulley can circumferentially freely rotate around pulley spindle, as long as a stable guide rail externally is set, pulley assembly just can help the stable operation of chain and actuator.
Description of drawings
Fig. 1 is the floor map of present embodiment;
Fig. 2 is the A-A sectional drawing of Fig. 1;
Fig. 3 is the sectional view of present embodiment;
The specific embodiment
Can know that with reference to figure 1, Fig. 2, Fig. 3 a kind of pulley assembly, pulley base 2 are provided with the axis hole 22 adaptive with main shaft 1; Pulley base 2 is set on the main shaft 1, and chain link 3 is fixedly installed on an end of main shaft 1, is used for being connected with outside chain link plate; Chain link 3 is wholely set with main shaft 1 in the present embodiment, but also split setting, and chain link 3 is the U type; On the inwall of chain link 3, be provided with the connecting hole 31 adaptive with outside chain link plate, and on pulley base 2, be provided with the pulley spindle 21 adaptive with pulley 4, pulley 4 is set on the pulley spindle 21; The type that is rectangle distributes, and between pulley 4 and pulley spindle 21, is provided with bearing, also is with bearing on the main shaft.
All sheathed bearing on main shaft and pulley spindle, this is in order to make pulley base and pulley rotating more smooth and easy, to reduce wear; Prolong the application life of pulley assembly; Certainly the form of bearing can have a variety of selections, and pulley is rectangle and is provided with on the pulley base, and this is not unique mode certainly; Pulley also can be difformity and be arranged on pulley base, such as triangle, square or the like.
