Design Of Transmission System Of Traction Oil Pumping Unit And Finite Element Analysis Of The Key Part

Traction Oil Pumping Unit is a new kind of oil pumping system. It has changed the designing idea of Traction Oil Pumping Unit. Show the very good technology characteristic in saving energy and reducing consumption, Because of frequently reversing, relatively large acceleration and heavy load will appear, and therefore exist the great impact in the whole pumping system. The power required is thus increased and the motor will have to work under unstable status. In such kind of machinery, every component or part such as oil extraction rod, pin gear bearing in the axle of the reduction gear, steel wire rope, etc, will be under the influence of impact. We expect that the power fluctuating magnitude of the motor can be decreased, the loaded situation in system be improved, energy consumption be reduced, and then the whole work system service life be enhanced. This is an important research topic which will determine the future development of Traction Oil Pumping Unit. With this idea, between the output axle of reducer and implementation system a vortex spring is added. Through theoretical analysis and experiment, it is shown that the sudden change of speed and impact in the pumping system is effectively lightened during positive and negative reversion of the friction wheel. System life is enhanced and the energy conservation has been reduced obviously.As a key part of the buffer, the vortex spring will affect buffing result directly and therefore, the elevator service life will be determined by its performance. In order to guarantee the reliability of vortex spring, the weary life-span being in progress to eddy spring analyses the key technology content being the main body of this paper.According to the state analysis of the Traction Oil Pumping Unit, the geometry parameter of the vortex spring is calculated in this paper at first. With the 3-D modeling software UG, the three-dimensional entity model of the vortex spring is set up. Secondly, through the IGES transformation filter that is in the large-scale finite element analysis software ANSYS, the model of the vortex spring entity is transferred into ANSYS software. Stress-strain analysis is carried out for the vortex spring. Finally, according to the analysis result, at the most dangerous point where the biggest stress appears, the fatigue life is analyzed. At the same time, analyze the driving and controlling of Traction Oil Pumping Unit .The traditional theory of the spring is verified according to above-mentioned analysis results. These analysis results for the optimization have provided the theory basis further. With the Traction Oil Pumping Unit apply the meeting to the oil exploitation field. The pre-research work done here will provide powerful support for the application.
