轴瓦的油槽如大功率柴油机连杆轴瓦油槽,一般收尾处都是按照铣刀圆弧半径自然收尾。为了减少气蚀易于形成油楔得到较好的润滑效果,现将设计成切向收尾或者从对接面切向切入,收尾切出的形式和油槽的加工方法介绍于下。 为了不停机加工出双向切向的目的,我们设计了轴瓦模座,安装在回转工作台上,使对刀时保证刀具的回转中心,与模座的回转中心在铣床工作台纵走或者横走方向在同一直线上。如图所示。 根据模座、轴瓦、刀具的几何尺寸可换算出OO′_1和OO′尺寸。则 O′O′_1=(OO′_1~2-OO′~2)~(1/2)

Bearing oil tank such as high-power diesel engine connecting rod bearing oil tank, the general end of the mill are rounded in accordance with the natural radius of the finisher. In order to reduce cavitation easy to form oil wedge get better lubrication effect, now designed to tangential end or tangential from the butt cut into the end of the cut out of the form and method of processing tank introduced below. In order to keep the machine out of the two-way tangential purpose, we designed the bearing mold base, mounted on the rotary table, so that when the knife to ensure that the tool center of rotation, and mold center of the rotary table in the milling table vertical or horizontal walking The direction of the same line. as the picture shows. According to mold base, bearing bush, tool geometry can be converted OO’_1 and OO ’size. O’O’_1 = (OO’_1 ~ 2-OO ’~ 2) ~ (1/2)
