一、引言牙轮钻机回转机构是钻机工作机构的一个重要组成部分,它的外形尺寸大小,特别是中心距尺寸的大小,对钻架整体尺寸有直接的影响,从而也影响到钻机的整体参数。为了能提高钻机的性能和减小钻架及小车的横断面尺寸,有必要对回转机构横向尺寸进行优化的探讨。本文就是针对这一点,在保证满足承载能力的前题下,对YZ—12型牙轮钻机的回转机构进行了优化设计,以达到最小的中心距尺
I. INTRODUCTION The rotary drilling rig rotary mechanism is an important part of the working mechanism of the drilling rig. Its dimensions, especially the size of the center distance, have a direct impact on the overall dimensions of the drill frame and thus affect the overall parameters of the drilling rig . In order to improve the performance of drilling rigs and reduce the cross-sectional dimensions of the rig and the car, it is necessary to optimize the lateral dimensions of the rotary mechanism. This article is for this point, under the premise of ensuring the carrying capacity to meet the YZ-12 type rotary drilling rig rotary body was optimized in order to achieve the minimum center distance ruler
