机器负荷
Explain peak and continuous load, start/stop frequency, shock events, braking, direction changes, shaft support and inspection access. These inputs help the quotation reflect the actual machine rather than an industry label.
螺旋斜面副在系统中的位置
Heavy-duty transmissions need a clear picture of how the load reaches the gear pair and how the shafts are supported. Bearing arrangement and housing stiffness matter because tooth contact depends on the position of the two members under load.
For maintenance replacements, add inspection history, visible damage and any measured changes in backlash. Damage patterns can help explain the service problem, but they should not be copied into the new geometry as if wear were part of the original design.

应用审核表
| 审查区域 | 提供什么 | 为什么这很重要 |
|---|---|---|
| 行动/职责 | Peak and continuous load, start/stop frequency, shock events, braking, direction changes, shaft support and inspection access | 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。 |
在生产前解决集成风险
A single “maximum torque” value can hide frequent starts, impact events or reversing load. Send the load spectrum and duty cycle when available, and identify whether the pair is exposed to overload or emergency events that the design must consider.
Heavy-duty or custom spiral bevel gear pairs are appropriate starting pages. Ground tooth finishing should be specified only when the drawing or performance requirement calls for that manufacturing route.
If a lifting or hoisting mechanism 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.
可考虑的产品系列
在发送询价之前
我是否需要在询价前知道齿轮的具体材质？
When the lifting or hoisting mechanism 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.
我可以只发送已安装设备的图片吗？
Photos of the lifting or hoisting mechanism 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.
询价单是否应包含完整的机器图纸？
For the lifting or hoisting mechanism, 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.
原型件的数量应该是多少？
For the lifting or hoisting mechanism, 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。
订购和配送指南
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。
