What is it made of?

01 机架、主轴衬套与两端方导套

示意铸铁 / 青铜

主轴有真实衬套孔;方导套上下及前后约束滑杆,保留0.02量级滑动净空。

02 开窗曲柄轮、轴肩与贯穿销

示意钢

轮缘与辐条可看见后方支承;驱动销穿过滑靴衬套,前端垫圈防止轴向脱离。

03 一体长槽轭与防转方滑杆

示意钢

槽净宽0.60、净高4.45;侧壁承受水平分力,足够长的双杆在极限位置也不脱出导套。

04 双凸缘滑靴与通孔衬套

示意青铜 / 钢

0.57宽滑靴在0.60槽内滑动;两侧凸缘跨过槽边作轴向保持,0.302孔配0.28驱动销。

How do the parts work together?

x=r cosθ,r=1.8;竖槽吸收r sinθ,输出严格简谐。两根方滑杆在整个3.6行程内始终穿过固定导套。

Model scope and approximations

AI-assisted educational schematic, not manufacturing CAD. Materials, proportions and movements are limited to this model's description.

间隙已几何显示但位移采用理想中心线约束;不计算摩擦、磨损、轴承载荷或弹性。
