Identify the complete assembly确认完整组件
A guide assembly includes the rail, block type, block quantity and their arrangement on the machine.一套导轨组件包括导轨、滑块形式、滑块数量及其在设备上的布置。
- Series, size and block style系列、规格与滑块形式
- Rail length, hole pitch and end distance导轨长度、孔距与端距
- Number of rails and blocks per axis每个运动轴的导轨与滑块数量
Calculate load and moment核算载荷与力矩
External forces, overhang and acceleration create moments that may control the rail size and block arrangement.外力、悬伸和加速度会产生力矩，并可能决定导轨规格与滑块布置。
- Vertical, horizontal and side loads垂直、水平及侧向载荷
- Pitch, yaw and roll moments俯仰、偏摆与滚转力矩
- Shock, vibration and required service life冲击、振动与目标寿命
Confirm installation and environment确认安装与环境
Mounting accuracy, preload, lubrication and contamination protection affect running quality and life.安装精度、预压、润滑及防污染措施会影响运行质量和寿命。
- Datum surfaces and mounting accuracy安装基准面与安装精度
- Accuracy and preload class精度与预压等级
- Lubrication, seals, bellows or covers润滑、密封、防护罩或风琴罩
