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。

选择点
这些是生产前需要解决的问题。
同心度和跳动
确定齿轮齿、孔/花键/轴和轴承座之间的基准关系。
责任
额定扭矩和峰值扭矩、转速、反转次数、冲击和寿命都会影响材料/工艺的选择。
检查
当牙齿或接口验证至关重要时，应在生产前确定报告内容。
替换和定制项目
Sun gears with through-bores or hollow interfaces for compact coaxial planetary arrangements.
For replacement hollow sun gears, verify bore fit, bore-to-tooth concentricity and the mating planet/ring geometry together. Photos can show the arrangement, but the controlled measurements determine interchangeability.
Bore size changes the section and the process plan
A large through bore or internal spline reduces the remaining section between the center feature and tooth root, so duty, wall thickness and distortion should be reviewed together.
For hollow sun gears, freeze the external tooth system and the bore or internal spline as one section before selecting the process route. The remaining wall thickness and gear-to-bore concentricity are central to the part definition.
If material and heat treatment are already specified, preserve them. If the bore size or internal feature is being changed, include torque and duty information so the effect on section strength and distortion can be reviewed.
Before approving production
Mesh confirmation
Verify tooth system and mating planetary geometry.
Interface confirmation
Verify bore/spline/shaft fits, datums and retention.
Process confirmation
Verify material, heat treatment, finishing and coating requirements.
Acceptance confirmation
Verify tooth, runout, dimensional and documentation requirements.
