+CONCEPT ONLY; DO NOT USE FOR CNC OR SAFE-FIT APPROVAL.
+Plate central bore nominal OD39, 8mm thick. 48mm KFL mounting pitch, nominal OD7 holes.
+KFL protrusion given b=38 as conservative circular OD38 bounding assumption, not confirmed round nor actual profile; 0.5mm radial nominal bore clearance.
+KFL ear thickness5.5, stationary central protrusion depth6, inner ring width14.5 and projects 10.5 past mating plane (KMT interpretation).
+Centre-hole to each fastening-hole nominal edge gap = 24 - 19.5 - 3.5 = 1.0mm.
+M6 plate-face washer assumed OD12, ID6.6, thickness1: towards centre hole it extends 1.5mm over nominal opening.
+Plate-face washer nominal contact area mm^2 (face-intersection):
+plate0 washer0: 67.367125

+plate1 washer0: 67.367125
+plate1 washer1: 67.367125
+These are static contact footprints, not load/fastener/tear-out calculations. Bearing ear footprint and flush contact require real KFL shape.
+Axial clearance must not be inferred from standard b width. Encoder screw, wires, set-screw access and rotational clearances not fully modelled.
+M6 heads/nuts/washer geometry is illustrative and no tool access is verified; M5 standard angles and crossing slots inherit prior notes.
+Diameter 39 is proposed initial 1mm diametral allowance and is not a fit/tolerance guarantee. No FEA, validation or testing.

+# KFL001 反装及 Ø39 板孔：装配概念
+
+此模型用于讨论，不是 CNC 文件或可装配强度证明。示意：150 mm 主轴、两只轴承、两块 8 mm 铝板、两侧 2020 型材和开关及接线 60 mm 包络，沿用上一版概念布局。法兰、电机前端、轴承顶丝、轴两端键槽及开关机构存在未建模或未实测事项。
+
+## 中心孔与轴承
+
+- 用户指定以 b=38 mm 考虑轴承座突起；模型以 Ø38 圆形包络表示穿板处，铝板中心孔 Ø39 mm，得到 0.5 mm 名义径向间隙。图纸的 b=38 是整体座体宽度，示意圆柱并非厂家直接标注的真实穿板截面。0.5 mm 尚未考虑实际轴承轮廓、公差、机加工和装配偏差。
+- KFL 安装孔中心距 48 mm，铝板安装孔按 Ø7 mm 画。中心孔和安装孔的最近金属宽度为 24−19.5−3.5=1 mm，单纯几何值不是承载判断，不能把它描述为一定会损坏。
+- 背板每个 M6 垫圈按外径 12、内径 6.6、厚 1 mm 示意。其靠大孔一侧在径向上约有 1.5 mm 投影落入大孔；按这个示意尺寸计算，每片垫圈与板接触面积约 67.37 mm²。这不是夹紧力或强度结论。轴承耳接触面、实际垫圈、螺丝头和螺母需按实物校验。
+- 按前版引用 KMT KFL001 的轴向尺寸，耳厚 5.5 mm、座体总深 11.5 mm、总轴向 16 mm，按凸起侧安装耳面为基准推算座体及内圈分别向孔里延伸约 6、10.5 mm。顶丝可能被孔壁挡住，工具可达性没有建模。
+
+## 对中与连接
+
+保留之前单边椭圆、一边圆孔的 2020 角码概念：角码长槽与铝板横槽交叉，型材另一侧圆孔配 T 型螺母。孔与 2020 槽在模型中均为示意，所有带载调整范围和紧固件工具路径未验证。轴承与板应作为整体移动，不能让 Ø38 凸起在 Ø39 板孔里作大范围对中移动。
+
+## 验证范围
+
+`geometry_check.txt` 记录孔距、垫圈面几何和列出的零件组合的正体积交叉；没有强度、轴向定位、实际顶丝、角码真实槽宽、线束、动态运动和制造误差检查。两块铝板和轴承主体的受力、螺栓夹紧与螺母空间需实物和结构核对。若之后导出 CNC 加工图，应先确定选定轴承的实际穿板轮廓和顶丝空间，以及板侧的螺母／垫圈承压条件。
