应用特定询价清单
| 范围 | 需要具体说明什么 |
|---|---|
| 职责数据 | Continuous or indexing duty, reversals, speed, acceleration and torque. |
| 几何学 | Backlash target, tooth quality requirement and planetary tooth counts. |
| 界面 | Spline/bore fit, concentricity datums and shaft/bearing arrangement. |
| 风险点 | Small errors in runout, fit or backlash can appear as positioning error at the machine. |
确认整个行星界面
In positioning systems, runout between the sun gear teeth and the shaft or spline datum can become visible as cyclic transmission error, so the datum structure belongs in the RFQ.
If a drawing is unavailable, combine gear measurements with backlash expectations, mating-gear data and the shaft/spline datum so the replacement can be reviewed for repeatability rather than appearance alone.
Precision motion considerations
Reversals make backlash, runout and interface fit visible in the machine, so the gear-to-spline or gear-to-shaft datum relationship matters.
For a new design, define the sun/planet/ring tooth relationship before finalizing the center interface. For replacement work, inspect the planets, ring, carrier support and lubrication condition so a new sun gear is not installed into an already damaged stage.
Use the application to decide which measurements deserve the most attention: peak torque and shock for heavy equipment, backlash and runout for motion systems, or life and documentation for long-duration duty.
