+CONCEPT ONLY; NOT ASSEMBLY FIT VALIDATION.
+Both flanges: disc OD57 thickness4, 6x PCD48 5.5 clearance; hub OD30 protrudes 20 from the base. Mirrored.
+Shaft nominal 12 x 125; z=-175.5..-50.5; motor hub z=-70..-50; motor insertion 19.5mm assumed and axial gap to base 0.5mm.
+Wheel hub z=-176..-156, front plate z=-180..-176; hub engagement 19.5 mm; plate bore overlap 0.0 mm (this is not extra key engagement).
+Bearing positions, 50mm switch envelope and cam as previous shifted design; rear/front hub clearance to simplified outer bearing 0.5mm nominal.
+KFL approximate 48 bolt pitch and 14.5 inner width, housing/protrusion guessed; 8mm plate 30.2 hole guessed; no real module shape, its 47mm hole is an assumption.
+Wheel70 is real STEP, mirror/phase0, rear face in contact with front flange disc, PCD48 hole centers align nominally; bolt direction, washer and tool clearances not checked.
+Real converter/70 STEP hole OD4.234, fastener M4 feasible only with washers and actual size checks; M5 cannot pass nominally; hole intersections/phase and actual hardware must be checked.
+Shaft endpoint keys not modeled; front hub insertion alone does not establish permissible torque. Actual axial gap, M3 nut, alignments, float bearing arrangement, switch/fan/angles, bolt heads, tool accessibility, and fit/strength not verified.

+# 125 mm 轴、两端相同法兰的装配示意
+
+## 文件
+
+- `125mm轴_装配示意.png`：展示 125 mm 轴和电机、两块铝板、两只 KFL 与开关的概念布局。
+- `Assembly.FCStd` / `Assembly.step`：完整示意装配。实体由脚本构建，不是参数化草图；请按脚本重建，几何不可作为加工定稿。
+- `geometry_check.txt`：名义尺寸、示意位置和已检查对象对的体积交叉结果。
+
+## 位置和尺寸
+
+- 主轴 Ø12 × 125 mm，在现有模型坐标 z=-175.5 到 -50.5；轴长度由几何直接创建。
+- 两端法兰相同：底盘 Ø57×4 mm、六孔 PCD48（通孔 Ø5.5 假设）、凸台 Ø30×20 mm；20 mm 按从底盘表面起算。方向盘侧连接已有 70 mm 转接板，电机侧连接已有小转接盘。
+- 当前仅做居中几何试排，两端轴各位于法兰凸台中约 19.5 mm，距法兰底盘内表面各约 0.5 mm。**电机中心的 M3 螺杆和螺母未建模，极可能占用电机侧的间隙；不得据此认定可装。**
+- 名义轴承与法兰沿轴向间隙为 0.5 mm；KFL 实物外形和工具空间未测，也不能认为间隙足够。
+- 两块铝板厚 8 mm；板孔 Ø30.2 mm 及 KFL 凸起 Ø29 mm 属示意假设，不是加工数据。
+- 开关 50 mm 是包括插座的轴向包络，以绿色透明长方体显示，不是实物轮廓；开口 Ø47 mm 为可视化假设，开关白色回正件未建模。轴套 20 mm 包含在开关包络内，不再叠加。
+- 轴承约按 KFL001 的 48 mm 安装孔距与 14.5 mm 内圈宽示意；顶丝、螺丝头及垫片、T 型螺母、调角器未建模。
+- 轴仅有中段轴套平键槽的示意，两端实际 4 mm 键槽、槽长和深度未建模。法兰通孔与已有盘名义约 Ø4.234 mm 孔之间，螺栓和垫圈实际匹配还须核对。
+
+## 检查及限制
+
+已对几何检查记录中列出的指定零件对作正体积交叉检查，未发现交叉。该结果仅涉及简化模型，不证明实物装配、旋转干涉、轴承同轴度、轴向定位/浮动、夹持强度或回正可靠性。图中开关、KFL 凸起及电机前端尺寸均需实测。轴端接近电机侧法兰底盘的位置尤其需要确认电机中心 M3 螺杆和螺母的避让；另一侧也须确认方向盘侧轴端及键槽空间。此文件不是 CNC 或打印文件。
