What is it made of?

01 机架、轴座与开放箱形导轨

示意铸铁 / 钢 / 青铜

后导面、上下侧导面和窄前压条捕获滑块;不以大银板遮住连杆和小端销。

02 开窗曲柄轮、主轴与大端销

示意钢

有轴肩的输入轴在通孔衬套中支承;0.40销轴穿入连杆大端。

03 带双眼衬套的连杆

示意钢 / 青铜

真实大端/小端眼与薄腹杆体连成一体;衬套和销轴分层可见,眼心距4.5。

04 受限十字滑块、开口叉与小端销

示意钢

滑块被四导面及窄压条限制;右侧回桥连接前后叉耳,左侧开放供连杆摆动。

How do the parts work together?

x=r cosθ+√(L²−r²sin²θ),r=1.6,L=4.5;连杆两销中心距恒为4.5,行程3.2。

Model scope and approximations

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

采用理想刚体闭环;可见销孔/导轨间隙未纳入回差,不计算侧推力、润滑、疲劳及制造公差。
