齿轮齿条

Model notes are in Simplified Chinese.

20 齿小齿轮、等节距直齿条、滑动导轨和固定轴承。

What is it made of?

01 承载导轨与轴承座

steel

两侧压板夹持齿条底翼;底部滑动垫条承受齿分离力,保留0.025示意间隙。

02 20齿渐开线小齿轮

steel

20°渐开线齿侧与同模数标准齿条啮合;轮毂有贯通键槽。

03 键连接阶梯轴

steel

铜衬套径向支承;轴肩和平键将输入转矩传入小齿轮。

04 20°直齿条与导向底翼

steel

节线y=-1.5;齿高2.25m,直线齿侧20°;加宽底翼在压板下滑动。

How do the parts work together?

齿轮节圆与齿条节线相切;齿条位移 x=rθ。本动画往复输入 θ=0.9 sin(t)。

工作运动:输入齿轮往复摆转,齿条按 x=rθ 同步平移;不是整体旋转。

Model scope and approximations

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

齿侧为离散渐开线和20°直线齿条;齿根非滚刀包络。保留齿侧/导轨教学间隙,未做制造公差、摩擦或端部限位动力学。
