内燃机上的主动齿轮与轮对轴的连接是过盈的静配合。主动齿轮的组装和拆卸需要在油压机上进行,其压力为1176±145千牛。这种装卸方法常常会使一、二个零件损坏。在这么大的力作用下轴常会弯曲。利用燃烧器对齿轮加热来减小压装力会导致局部过热和轮齿淬火表面回火。现研制出一种新的工艺方法和装置,它能在对ТУ型内燃机车车轴与齿轮作组装(或拆卸)时保持零件的完好。根据该工艺车轴与齿轮的组装和拆卸是用感应加热法来进行的,即将齿轮置于感应器内加热,直到其温度能保证零件相互间可自由移动(或稍
The connection of the driving gear on the internal combustion engine and the wheel axle is an interference static fit. The assembly and disassembly of the driving gear need to be done on a hydraulic press with a pressure of 1176 ± 145 kN. This loading and unloading method can often damage one or two parts. Under such a great force, the shaft often bends. Using a combustor to heat a gear to reduce the press-in force can result in localized overheating and gear tempering. Now developed a new process methods and devices, which can ТУ type diesel locomotive axles and gears for the assembly (or removal) to maintain the integrity of the parts. According to the process of assembly and disassembly of the axle and gear is carried out by induction heating method, the gear is placed in the sensor heating until its temperature to ensure that the parts are free to move between (or slightly
