Explain repeatability, low lost motion, shaft alignment, thermal behavior, bearing preload, lubrication and inspection scope. These inputs help the quotation reflect the actual machine rather than an industry label.
A precise gear pair still depends on the machine structure that positions it. If the housing or bearing stack moves the gear away from the intended mounting distance, the tooth contact can shift even when both gears were made to the drawing.
When a project has temperature-sensitive behavior, include the operating range and the materials around the gear pair. Do not turn that context into a product-level performance claim unless the ordered configuration has been evaluated for it.

| 审查区域 | 提供什么 | 为什么这很重要 |
|---|---|---|
| 行动/职责 | Repeatability, low lost motion, shaft alignment, thermal behavior, bearing preload, lubrication and inspection scope | 将稳定的动力传输与反向、冲击或位置敏感的工作状态分开。 |
| 齿轮组 | 齿轮和小齿轮的标识、传动比/齿数和手动 | 防止在缺少配合几何形状的情况下对单个组件进行审查。 |
| 安装 | 轴系布置、轴承支撑、壳体基准和目标齿隙 | 将制造好的零件连接到它在装配体中应占据的位置。 |
| 环境 | 润滑、温度和污染环境 | 支持对实际的材料、表面处理和服务进行审查,而不捏造机器级别的声明。 |
| 检查 | 图纸公差、齿面光洁度和所需记录 | 定义买方将使用何种方式接受订购的配置。 |
Tighter numbers are not automatically better if the machine cannot hold them. Define the values that the assembly can control, and state which surface or axis is the reference for each acceptance dimension.
Ground or custom matched pairs are typical starting points for higher-control applications. A pinion shaft can reduce separate joint interfaces when the design intentionally integrates the shaft and pinion.
If a precision machine assembly still has open geometry or duty inputs, mark those items for review. An explicit unknown is safer than filling the drawing with an assumed standard value.

When the precision machine assembly drawing controls material or heat treatment, include the exact requirement. If those choices remain open, describe the duty and leave material/process selection for review.
Photos of the precision machine assembly help establish orientation and condition, but they do not define tooth geometry or mounting datums. Add the mating member, drawing data and measurements taken from controlled assembly references.
For the precision machine assembly, send the assembly information that controls shaft relationship, mounting datums and interfaces. Unrelated machine details can be omitted when they have no effect on gear selection or inspection.
For the precision machine assembly, separate prototype/sample quantity from expected repeat demand. This keeps tooling, inspection and production planning tied to the real purchasing stage.
配合关系和装配数据定义得越清楚,配置审查的速度就越快。
最小起订量 (MOQ) 根据产品类型、生产工艺和订单总额而定。合适的全新项目可以按样品价格索取 1-5 件样品。当订单总额达到约 1500 美元时,可以合并不同型号的产品。1-2 件的订单也可以考虑,但单价通常会更高。
标准件的典型计划周期为 10-25 个工作日,定制件为 20-45 个工作日,项目型设备或组件为 45-120 个工作日。通常支持 EXW、FOB、CIF 和 DAP 等贸易条款;FCA、CFR、CPT、CIP 和 DDP 等运输方式可另行商议。
