Define the motion requirement定义运动要求
Travel, speed, acceleration and positioning accuracy determine the basic screw arrangement.行程、速度、加速度和定位精度决定丝杆的基本方案。
- Effective travel, total length and available space有效行程、总长及可用空间
- Target speed, acceleration and duty cycle目标速度、加速度与工作循环
- Positioning accuracy and repeatability定位精度与重复定位精度
Confirm load and rigidity确认载荷与刚性
Axial load, expected life, mounting span and critical speed must be reviewed together.轴向载荷、预期寿命、安装跨距和临界转速需要一起核对。
- Working load, peak load and external forces工作载荷、峰值载荷及外部作用力
- Preload and axial rigidity requirement预压及轴向刚性要求
- Mounting orientation and support arrangement安装方向与支撑方式
Send end details before ordering订购前提供端部细节
End machining controls compatibility with bearings, couplings, motors and support units.端部加工决定与轴承、联轴器、电机及支撑单元的兼容性。
- Dimensioned shaft-end drawing带尺寸的轴端图纸
- Nut type, flange orientation and lubrication螺母类型、法兰方向及润滑
- Fixed and support-side unit requirements固定端与支撑端单元要求
