As a biopharmaceutical system subject to stringent aseptic requirements, the machine is designed with all drive units positioned beneath the worktable. Within this constrained space, the mechanical layout coordinates material transfer, lifting and positioning, and pushing mechanisms across a six-station process.该项目为生物医药项目，对于无菌性要求非常高，要求驱动装置全部布置在工作台下方。机械布置需要在这一安装空间内，围绕六工位流程协调转运、升降定位与推装机构。

The bevel stage turns the drive direction within the below-platform layout. A belt ratio of 2 and a gear reduction of 8 give a nominal overall ratio of 16; this ratio describes the design concept, not verified positioning accuracy.锥齿轮级在台面下方的布置中改变传动方向。方案中的 V 带传动比 2 与齿轮减速比 8 对应总传动比 16，用于说明理论传动方案。定位精度尚未验证。
Design Approach设计方法
Mechanical architecture机械传动与执行方案
Rotary drive转盘驱动
I developed the mechanical structure and 3D assembly around an AC servo, a V-belt and a two-stage bevel-and-spur reduction, connecting the below-platform drive to the rotary transfer mechanism.我围绕交流伺服、V 带及锥齿轮—直齿轮二级减速结构，完成机械结构与三维装配设计，将台面下方驱动联系到旋转转运机构。
Vertical positioning升降定位
My engineering calculations and component selection covered the ball screw and linear guides that move the platform. The screw lead, support arrangement and vertical-load calculations still need review before final speed, torque or life figures can be stated.我的工程计算与零部件选型包括平台升降用的滚珠丝杠和直线导轨。丝杠导程、支承方式及垂直载荷计算仍需复核，才能确定最终转速、扭矩和寿命结论。
Pneumatic insertion气动推装
I chose pneumatic insertion as part of the mechanical layout. The original force calculation contains an arithmetic error, so the actual insertion force and effective air pressure must be established before the final cylinder is selected.我在机械布置中采用气动推装方案。原推力计算存在算术问题，最终气缸选型前需要重新确定实际插入力与有效气压。

View Calculation Details展开计算过程
Pd = KA P = 1.2 × 1 = 1.2 kW
ibelt = D/d = 2; itotal = 2 × 8 = 16
L ≈ 2a + π(D + d)/2 + (D − d)²/(4a)
b = L − π(D + d)/2; a = [b + √(b² − 2(D − d)²)]/4
For L = 800 mm, the approximate length equation gives a ≈ 207.65 mm. At the original design estimate of 207.5 mm, the same equation gives L ≈ 799.7 mm; the small difference reflects the approximate center distance used in the original design.带长 L = 800 mm 时，近似长度式得到中心距 a ≈ 207.65 mm。将原设计近似值 207.5 mm 回代，同一公式得到 L ≈ 799.7 mm；这一小幅差异对应原设计采用的近似中心距。
α = 180° − 2 asin[(D − d)/(2a)] ≈ 157.79°
α ≈ 180° − 57.3°(D − d)/a
Tangent geometry gives 157.79° at the recomputed center. The small-angle estimate at 207.5 mm gives 157.9°, consistent with the original design estimate of 157.9°. These values use different approximations.按复算中心距，切线几何包角为 157.79°。在 207.5 mm 中心距下，小角度近似得到 157.9°，对应原设计的 157.9°；两者采用的近似方法不同。
