[Abstract]:The purpose of this paper is to provide advanced equipment and technical support for the scientific drilling project of Songke well No. 2, based on the national deep exploration technology and experimental research project 尉 SinoProbe-09-05.The crustal No. 1 hydraulic top drive is the core of the whole 10,000 meter drilling rig, and the main drive system is the core of the whole top drive. Its main function is to transfer the hydraulic power source to the hydraulic motor and the planetary reducer to the brake gear reducer.Finally transfer to the center shaft of top drive to complete drilling workThe main characteristics of the main drive system of the crustal No. 1 hydraulic top drive are that the rotational speed is high, the torque is large and the speed range is wide, the performance meets the requirements of hard core drilling technology in deep wells, the research status of top drive at home and abroad is analyzed and compared, and the characteristics of scientific drilling engineering are combined.Finally, the scheme of main drive system for top drive is establishedFirstly, according to the working principle of hydraulic top drive gear reducer, the gear reducing speed and increasing torsion mode is selected, the gear parameters are calculated by using the relevant knowledge of mechanical science, and the results of tooth surface contact strength and tooth root bending strength are compared.The gear parameters are determined, and Autodesk Inventor software is used to establish the three-dimensional model of the gear. The dynamic contact transient dynamics analysis of the gear is done by ANSYS Workbench software. The reasonable and reliable gear parameters are obtained by using the mechanical theory and virtual prototyping technology.The strength and stiffness of the center axis of top drive are checked, and the static analysis and fatigue analysis are carried out by using virtual prototype. Under the action of simulated hole accident and limit load, the force of the center axis of top drive is still within its yield strength range.And has a high life and safety factor, to meet the design requirements of the crustal No. 1 hydraulic top drive for the main transmission system of the main parts purchased,For example, hydraulic motor, planetary reducer, brake, thrust bearing, expansion coupling sleeve and so on are analyzed and selected, and the bearing and expansion coupling sleeve are checked.This paper provides a reference for the design of the whole top drive system, at the same time provides a new idea for the optimization design of the structure of the main drive system. The reliability of the main drive system is guaranteed from the theoretical analysis and the simulation of the virtual prototype.Increasing Security for the next Top Drive Application
