Problems solved by technology

One end of the steel cable lifting belt is fixed on the driving drum, and the other end is connected to the oil production rod. The steel cable lifting belt is wound repeatedly on the driving wheel (about 6,000 times per day). The machine brings the following adverse effects: 1. The steel cable belt wears too fast, resulting in frequent replacement of the steel cable lifting belt on site, excessive loss and excessive labor intensity; 2. The torque cycle of the driving wheel changes, and the motor current increases and changes accordingly , so that the transmission steel cable lifting belt and the oil production rod connected to it will vibrate periodically, and at the same time, the friction load, inertia load and vibration load will increase, which will affect the normal operation of oil production

Embodiment Construction

[0007] Concrete structure of the present invention can refer to accompanying drawing: among the figure, drive wheel excircle is designed into an involute type, progressive circle wheel diameter 600mm-1200mm, progressive difference is 0-360 °=steel cable hoist belt thickness. The thickness of the steel cable lifting belt is 6mm-60mm. The arc-shaped pressing plate 4 of the downward 90° position at the drive wheel steel cable hoisting belt outlet is designed as a structure that can be fixed and disassembled with bolts. One end of the arc-shaped pressing plate 4 is crimped to the rotating pressing plate 6, the rotating pressing plates 6, 8 are coaxially hinged on the shaft 7, and the movable end of the rotating pressing plate 8 is the outlet of the steel cable lifting belt. The inside of the driving hub is designed in the form of locking the steel cable hoist belt with fixing bolts. The specific embodiment of above-mentioned structure sees figure 1 One end of the steel cable hoi...

Abstract

The present invention relates to a driving mechanism for oil production machine. The driving wheel for steel cable lifting belt is designed as involute one with progressive wheel diameter of 600-1200 mm, progressive difference of 0-360 deg and thickness equal to that of steel cable lifting belt. The present invention has no irregular winding of steel cable lifting belt, no tingle and thus produced friction, inertia and vibration load in pumping rod and can ensure the service life of steel cable lifting belt.

Description

technical field [0001] The invention relates to a power transmission device of an oil extraction machine, in particular to a driving wheel of a steel cable hoisting belt of an oil extraction machine. Background technique [0002] The traditional digital automatic oil extraction machine is directly connected with the motor, the reducer, and the driving wheel shaft, and the sucker rod is driven by the steel cable lifting belt for oil extraction. One end of the steel cable lifting belt is fixed on the driving drum, and the other end is connected to the oil production rod. The steel cable lifting belt is wound repeatedly on the driving wheel (about 6,000 times per day). The machine brings the following adverse effects: 1. The steel cable belt wears too fast, resulting in frequent replacement of the steel cable lifting belt on site, excessive loss and excessive labor intensity; 2. The torque cycle of the driving wheel changes, and the motor current increases and changes according...
