曲柄滑块机构
曲柄滑块:有孔连杆双眼、青铜衬套、叉式十字头与开放式箱形导轨。
What is it made of?
01 机架、轴座与开放箱形导轨
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
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
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
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。
