The invention discloses a traction gear of a bogie of a high-speed railway locomotive and a modification method and application of the traction gear of the bogie of the high-speed railway locomotive. The method has the beneficial effects that the pressure change value curve of each tooth on the outer surface of the tooth profile of the to-be-detected gear is acquired in real time and is compared with the deviation condition of the pressure change value of each corresponding tooth in the standard bogie traction gear, so that the high-speed railway locomotive bogie traction gear is subjected to shape modification; the gear teeth are elastically deformed when being loaded, so that the meshing contact spots of the tooth surfaces are reduced, the impact load is reduced, the operation tends to be stable, the noise and vibration are reduced, the modification stability of the traction gear is improved, and the traction work of a bogie is stably carried out. Then, tooth direction modification design is carried out, comparison of basic tooth surfaces is achieved through gear hobbing during machining, the deviation condition of the pressure change value of each corresponding tooth is compared, and the deviation is recognized.
本发明公开了一种高速铁路机车转向架牵引齿轮及其修形方法及其应用,包括轴体,本发明的有益效果是:通过实时采集待测齿轮的齿廓外表面每个齿牙的压力变化值曲线与标准的转向架牵引齿轮中相对应的每个齿牙的压力变化值的偏差情况进行比对,实现了对高速铁路机车转向架牵引齿轮的修形避免因扭矩过大,轮齿受载而产生弹性变形,使齿面啮合接触斑点降低,降低冲击载荷,使运转趋于平稳,减小噪音和振动,提高了牵引齿轮修形的稳定性,稳定进行转向架牵引工作,与现有技术设计出具有恒定变位系数和公法线的基本齿面,然后进行齿向修形设计,加工时通过滚齿实现基本齿面的相比,对相对应的每个齿牙的压力变化值的偏差情况进行比对并对偏差进行识别。
