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
External sun gears for planetary transmissions, quoted from the tooth system, mating gear geometry and bore/interface drawing.
For replacement standard sun gears, confirm the tooth system and mating planet/ring geometry before using outside diameter as a selection reference. Photos help identify the layout, but measured tooth data control the part.
Standard sun gear selection beyond the basic dimensions
Use the complete planetary mesh to validate the part. Outside diameter, tooth count and face width are useful checks but do not replace pitch system, pressure angle, profile shift and mating-gear data.
For standard discrete sun gears, freeze the mesh geometry and the locating bore or spline before selecting the tooth-cutting and heat-treatment route. Replacement work should compare the existing planets and ring so worn mating geometry is not treated as a new design target.
Where the source drawing already controls material, heat treatment or tooth accuracy, keep those requirements unchanged. If the drawing is incomplete, add duty data only to close the missing manufacturing decisions.
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.
