摘要
本文采用坐标网格法分析了冷挤压内斜齿轮时的力学特点 ,实验结果给出了变形区不同区域的应变特征和毛坯表面变形区内应力应变值及其变化规律 ,指出了变形区的外部边界和可能破坏的区域。给出的结果为计算变形力奠定了基础。
This paper analyzes the mechanical characteristics of internal helical gear manufactured by cold extrusion through the dividing grid method. Experimental results give the strain characteristics of different zones, magnitude of stress-strain in the zones of deformation, demonstrate the outside boundary of the deformation zone, and point out the zones vulnerable to destructions. The results provide a basis to the calculation of deformation forces.
