行星齿轮啮合
确认啮合齿数、节距系统和压力角,而不是单独识别太阳轮。
| 范围 | 需要具体说明什么 |
|---|---|
| Gear teeth | Sun-gear module/DP, pressure angle, tooth count and helix/profile data. |
| Spline | Internal or external spline per controlled drawing/standard. |
| Spline fit | Fit class, effective length and inspection/gauge requirement. |
| Datums | Runout and concentricity relationship between gear teeth, spline and faces. |
| 材料/热处理 | Per drawing and duty. |
| 检查 | Gear and spline inspection scope agreed before production. |
这些是生产前需要解决的问题。

Sun gears with spline interfaces for planetary drives requiring positive torque transfer and controlled concentricity.
For a replacement splined sun gear, verify both the planetary mesh and the spline standard, fit and datum relationship. Photos help identify the assembly, but spline and tooth measurements control the part.

The external gear teeth and center spline are separate precision interfaces. Spline fit, effective length and concentricity to the gear teeth all influence assembly and load distribution.
For splined sun gears, the external gear and spline must be reviewed as two linked tooth systems. The spline fit and effective length should be confirmed together with the external gear datum before process planning.
Preserve the specified gear and spline standards when available. If the original spline is worn, use the mating shaft or hub to separate service wear from the intended fit before the part is released.

Verify tooth system and mating planetary geometry.
Verify bore/spline/shaft fits, datums and retention.
Verify material, heat treatment, finishing and coating requirements.
Verify tooth, runout, dimensional and documentation requirements.
