Description
Technical field
The utility model relates to a kind of oil pumper that is used for petroleum industry machinery oil production, specifically, relates to the rotary-type oil pumper of arc pendulum rod variable torque balance reducing.
Background technology
The energy consumption height of existing conventional beam pumping unit, heaviness; Though the energy consumption of upper cross-beam torque-variation, balancing beam type machine for pumping oil from deep well has bigger reduction, not enough, and also heavier, more complicated.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective, and the rotary-type oil pumper of arc pendulum rod variable torque balance reducing a kind of simple in structure, energy-conservation is provided.
The rotary-type oil pumper of arc pendulum rod variable torque balance reducing described in the utility model, comprise motor, belt gear, crank-link mechanism, reducer, movable support, fixed support and base, also has arc pendulum rod, the reducing runner, the crank end face of described crank-link mechanism has crankwheel, and the slideway of the rear end of described arc pendulum rod is sleeved on the crankwheel, and its front end is fixed on the base by fulcrum shaft, described reducing runner is installed on the wheel shaft on movable support top by wheel shaft, link to each other with crossbeam with soft driving member between reducing runner and the arc pendulum rod, the lower end of described movable support fixes on the fixed support with hinges fixing, and fixed support and reducer are installed on the base.
The slideway of described arc pendulum rod is the hole of oval arc shape.
Described reducing runner has the moving runner of the minor diameter at the sectional wheel of anterior orthodrome diameter and rear portion, and two parts are an integral body, have same axial line.
Advantage of the present utility model:
The utility model designed arc pendulum rod variable torque balance mechanism and reducing runner, strengthened variable torque balance than, reduced last lower dead center place's fork and the crankwheel rotational circle angle between crank center line and main shaft vertical center line when tangent; Soft driving member and reducing runner are tangent all the time, have improved equilibrium conditions transmission condition and stress condition, make this oil pumper than two conventional pumping units energy-conservation percent 70%; In light weight percent 15%, structure is also fairly simple, operates also more conveniently, and machine volume is smaller.
The utility model is used to manufacture and design new oil pumper, and arc pendulum rod mechanism also can be used for the transformation of conventional beam-pumping unit technical application.
Description of drawings
