摘要
提出了一种八臂式分动机械推靠器的实现方法。根据需要完成的功能确定推靠器的工作方式,设计它的机械结构和参数,并对推靠机构各部件进行力学分析,得出驱动压盘的力F和推靠力F0的函数关系式,代入结构参数的设计值,在整个推靠域上得出推靠力F0和抱紧力的极限值,并对动力传动机构进行分析。经过测试和现场应用,八臂式分动推靠器机械结构和参数设计合理,极板贴靠井壁严实,动力设计符合实际应用要求,机械性能稳定可靠。
A design method for the respectively-moving octal-arm sonde was presented. The sonde’s working mode is determined according to its function to be realized,then the mechanical structure and parameters of the sonde are designed. The functional relation between the driving plate force F and the sonde’s power F0 is established based on the mechanical analysis of every component in the eccentering machinery,and the sonde’s power limit value F0 and its withdrawing force are calculated on its whole working domain by substituting the design values of its structure parameters into the function expression obtained. The power transmission mechanism is also analyzed. Field test and practical application show that the mechanical structure of the sonde and the design values of its parameters are reasonable,and its pads adhere to the sidewall tightly. This sonde has a good reliability in the field application,and its withdrawing force meets the actual requirements on its whole working domain.
