Precision Gear Racks for Custom Machinery
Special machinery often needs the accuracy discipline of a catalogue precision rack while keeping drawing-specific holes, ends, section geometry or inspection datums. This is where standard tooth systems and custom machining frequently meet.
机架驱动器需要做什么
The right question is not whether the part is “standard” or “custom.” The useful distinction is which features are fixed by a tooth system and which features belong to the machine design. Keeping those two groups clear makes quotation, production and inspection easier.
该应用应被视为一个完整的系统。这意味着需要将齿条齿系统、小齿轮、变速箱接口、安装底座和润滑方式等因素结合起来进行评估，而不是仅仅假设齿条本身决定性能。
在固定部件之前，先确定机器的运行工况。
这些输入参数决定了报价是仅仅基于几何形状还是反映了驱动器的实际使用方式。
| Functional datums | Which surfaces locate the rack and which dimensions control the mesh. |
|---|---|
| 牙齿数据 | Module/pitch, pressure angle, tooth form, helix angle and quality requirements. |
| 二次加工 | Hole pattern, counterbores, dowels, ends, shoulders or reliefs. |
| Material/process | Material grade, heat treatment, finish and coating if any. |
| Production plan | Prototype quantity, validation batch and repeat production demand. |
此应用中常用的评估产品
以下选项仅供参考，并非自动选择。最终适用性取决于图纸和运行数据。
安装细节决定了精密机架的价值，或使其贬值或得以保留。
Make the drawing datum scheme match the way the part will be mounted and inspected. That reduces arguments about dimensions that are technically correct but referenced from the wrong surface.
If the rack joins another section, identify the required end relationship and how the joint will be set during machine assembly.
When a prototype is used to validate the design, record any approved changes before the production batch so the revision history stays controlled.
申请咨询时需提交的信息
Send the current drawing revision, 3D model when useful, controlled datums/tolerances, tooth data, material and heat treatment, prototype quantity and expected repeat quantity. Note which dimensions are function-critical and which can be adjusted for manufacturability.
如果某些值尚未确定，请将其标记为设计目标。这比插入一个以后难以更改的猜测性规范更有用。
请发送零件的详细信息。
一份有效的报价应从几何形状和运行环境入手。请提供图纸、数量和控制要求；对于齿条驱动轴，请提供行程、速度、加速度、负载以及配套小齿轮或齿轮箱的信息（如有）。
订购： 最小起订量 (MOQ) 根据产品类型和订单金额而定。新客户样品起订量为 1-5 件；混合型号订单总金额在 1500 美元以上时可接受，而 1-2 件的订单单价会更高一些。
时间安排及条款： 标准零件的交货期通常为 10-25 个工作日，定制零件为 20-45 个工作日，项目设备的交货期为 45-120 个工作日。EXW、FOB、CIF 和 DAP 是常用的交货方式；FCA、CFR、CPT、CIP 和 DDP 可以根据具体情况讨论。
