传统的活塞销由于润滑油管道开口端应力集中,易产生裂纹。必须在开口处倒角以减小应力集中。这样加工困难,又浪费工时。本方案克服上述缺点(其结构如图所示),沿实心活塞销的外柱面母线开多个油孔,其在侧视图上与销轴线正交,且向轴心线倾斜。 The traditional piston pin due to stress concentration of the open end of the lubricating oil pipe, easy to crack. Chamfering must be done at the opening to reduce stress concentration. This process is difficult, but also a waste of working hours. The solution to overcome the above shortcomings (the structure shown), along the solid piston pin outer cylinder busbar open a plurality of oil holes, which in the side view orthogonal to the pin axis, and tilted toward the axis.
