Abstract

The invention discloses an oil pumping unit speed reducer with a safety protection function, and relates to the technical field of oil pumping equipment for petrochemical engineering. The oil pumping unit speed reducer comprises a machine shell, a speed reduction shaft is rotatably arranged in the machine shell, a first transmission wheel drives a first transmission shaft to rotate, and a second transmission wheel on the surface of the first transmission shaft and the first transmission wheel synchronously rotate, so that a brake protection wheel is driven to rotate in the machine shell, a third transmission wheel rotates in the machine shell through mutual meshing between the brake protection wheel and the third transmission wheel, and a speed reduction gear outputs rotation of the speed reduction shaft; and the first transmission wheel, the second transmission wheel, the third transmission wheel and the brake protection wheel are matched with one another, so that matched transmission of multiple stages of gears is completed, the rotating speed and torque of a motor are changed, the efficiency of the motor is effectively improved, large torque can be obtained with small power consumption, and the energy consumption of the oil pumping unit in the using process is reduced.

Description

technical field [0001] The invention relates to the technical field of oil pumping equipment for petrochemical industry, in particular to a speed reducer for an oil pumping unit with a safety protection function. Background technique [0002] There are five types of current reducer devices; the first one, which is currently the most widely used and sold on the market, is the JHL type special reducer for oil pumping units; it uses double circular arc toothed cylindrical gears ; The second type, hard gear reducer for oil field; the third type, special cycloidal pin gear reducer for pumping unit; the fourth type, three-ring reducer is driven by three identical inner tooth ring plates to drive an external gear output , so it is called a three-ring reducer, which belongs to the parallel shaft-moving shaft gear transmission reducer. The gear meshing motion belongs to the driving shaft gear train, which has the characteristics of planetary transmission with small tooth difference. ...
