QY3型石油管道牵引机主机设计
摘 要
石油管道牵引机研究的是在油田工地的输送油管装置的机器，就是在油田工地作业时对输油管其牵引作用的机械装置。此牵引机可以提供连续传输油管时的牵引力，它主要由主机部分、齿轮基座、减速装置、传动装置、输送装置等几部分组成。本课题是设计牵引机的主机部分。需要对输油管牵引机械进行特性分析、整体方案的拟定、动力机的选择等工作。并对输油管牵引机整体系统的各个零部件进行详细的设计计算、强度校核、和图纸设计，要包括输油管牵引机主机中主要零件，如轴、滚筒、支架、轴承座、键螺钉及螺母等的设计校核与选用，也对牵引机的机体等进行结构设计和分析。

QY3 oil pipeline the tractor host design
Abstract
Oil pipeline traction research machine conveyor tubing in the oil field site installations in the oil field site operations' s pipeline of its traction mechanism. This tractor can provide traction when the continuous transmission pipeline, it mainly consists of the host portion of the gear base, deceleration device, transmission device, conveying device composed of several parts. This topic is the host portion of the design of tractor. The need for pipeline traction mechanical characteristic analysis, the formulation of the overall program, the power machine of choice. The various components of the traction machine overall system and pipeline detailed design calculations, the strength check, and the design drawings, to include the main parts in the pipeline tractor host, such as shafts, rollers, brackets, bearing key screws and nuts, etc. design verification and selection, structural design and analysis of the tractor body.
Keywords: tractor, the host, delivery device
