+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 150; z=-206.5..-56.5; motor hub z=-70..-50; motor insertion 13.5mm assumed and axial gap to base 6.5mm.
+Wheel hub z=-213..-193, front plate z=-217..-213; hub engagement 13.5 mm; plate bore overlap 0.0 mm (this is not extra key engagement).
+Rear bearing retained; front bearing shifted 25mm forward from the 125mm layout; switch 60mm with 13.5mm nominal gap on each side, cam shifted 12.5mm; 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; 60mm switch/wire envelope placeholder, 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.

+# 150 mm 轴与 60 mm 开关：装配示意
+
+这是未实测结构的概念布局，不是 CNC 加工图，也不能证明实物可装。
+
+与 125 mm 方案相比：电机及后轴承、后铝板、后法兰位置不变；前轴承及铝板、方向盘侧法兰和 70 转接板朝方向盘前移 25 mm。轴本体电机侧端点保持原位，前端延长 25 mm，故轴长由 125 增至 150 mm，轴几何中心及轴套向前移动 12.5 mm。开关含接线的 60 mm 包络保持 60 mm 长并随之向前移 12.5 mm。下方两根 2020 型材从示意长度 200 mm 延长为 225 mm；尺寸仅用于布局，连接件和强度未验证。
+
+轴承内圈中心距由 76.5 mm 改为约 101.5 mm；60 mm 开关包络与两侧内圈各约 13.5 mm。两侧 Ø30 × 20 mm 法兰凸台与轴各有约 13.5 mm 的轴向重叠，轴端距法兰底盘内表面各 6.5 mm。两个法兰与示意轴承座的名义间隙约 0.5 mm。以上都是此假设模型的几何尺寸，不是实际装配或键连接强度结论。
+
+已有灯光开关照片只能提供外观；绿色透明物是完整 60 mm 包络，中心 Ø47 孔纯为示意，并非实测可转空间。白色回正件、接线弯曲、两侧轴承凸起、孔径和顶丝、真实轴两端键槽与键长、轴承定位与浮动、电机中心 M3 螺母及紧固件工具路径都未验证。开关的 20 mm 轴套已位于 60 mm 包络内，不能再次累加长度。
+
+8 mm 铝板轴孔 Ø30.2 mm、KFL 中央凸起 Ø29 mm 均为占位假设；不可作为加工尺寸。两块实物转接盘 STEP 的孔径约 Ø4.234 mm，法兰 M5 通孔不能直接穿 M5 螺丝，M4/垫片配合须对照实物和强度。电机前端尺寸也是近似。
+
+`geometry_check.txt` 记录了模型中列出的对象的正体积交叉检查，不能证明未建模对象、动态运动、承载力或装配可行。两个轴承座应安装于与电机一起调角的框架，并结合实物解决三处旋转支撑的同轴和轴向定位问题。
