摘　　要：小齿轮空心轴驱动装置可应用于1050 mm轮径的高速机车转向架,其特点是可有效减轻轮对驱动装置。文中对采用小齿轮空心轴驱动装置的三轴转向架进行了研究,该转向架基于某集成式双源机车的运用需求,针对三轴转向架中间轮对横动量较大的特点,明确了转向架设计目标,重点阐述驱动装置的结构、联轴器的选型、电机顺置和对置的对比分析以及转向架的主要结构组成等。研究结果表明,转向架各项性能均能满足设计要求,相较于采用1250 mm轮径、轮对空心轴驱动结构的轮对驱动装置,每条轮驱减重2 t以上,轻量化效果显著。Joint shaft inside hollow pinion driving device can be used to highspeed locomotive bogie of 1,050 mm wheel diameter,which characterized by effective weight reduction of wheel set and driving device.This paper introduces the research of three-axle bogie of joint shaft inside hollow pinion driving device,the bogie is based on one integrated dual-source locomotive,considering the characteristics of large transverse momentum of middle wheelset of three-axle bogie,specified design target of the bogie.Emphatically introduce the structure of the driving device,the selection of couplings,the comparative analysis of the motor arrangement,the main technical parameters and the structure of each part of the bogie.Research result shows that each performance of the bogie meets design requirement,comparing to 1,250 mm wheel diameter and joint shaft hugging axle driving device and wheelset,it reduces the weight more than 2 tons,lightweight effect is remarkable.
