针对管道检测牵引装置驱动系统中没有差动机构而引起的通过弯管时产生运动干涉的问题,将差动机构应用于管道检测牵引装置中。通过对差动机构进行理论分析,建立该轮系的力矩传递方程;利用ADAMS软件建立差动机构的样机模型并进行仿真分析。结果表明,具有差动机构的管道检测牵引装置驱动单元结构简单、驱动效率高、功率体积比大,可实现机械自适应功能。 Without differential mechanism in the drive system of pipeline inspection traction device,locomotion interference can be produced anciently when the robot is getting across the elbow.The tri-axial differential gearing system was applied to the traction device.The equations of momentum transfer in tri-axial differential gearing system were set up via theory analysis.The model of prototype machine was set up through ADAMS software and the simulation analysis was carried out.The results show that the traction device with differential mechanism has simple configuration of the drive cell,high drive efficiency,big ratio of power and cubage,and can achieve the function of mechanical self adapting.
