Chamfering can be achieved by Vehicle Processing chamfering, and chamfer angle 30 degree (left and right) is proper, and angle is too small, is welded into
Type face is bad, has stomata；Angle is too big, and welding splash-proof effect is deteriorated, and 30 degree of (left and right) angles are drawn by test of many times
, the T-shaped shaft assembly of this angle and planet carrier forms 30 degree of angles, reach secondary anti-splashing (i.e. laser reflection when produce
Splashing) effect.
A chamfering is done in the solder side of p-type support, a narrow and small inner chamber is formed, metal caused by laser welding is flown
Granular absorption is splashed in inner chamber sharp corner, and obstructs stray laser, reaches secondary anti-splashing, is finally reached the preferable effect of anti-splashing
Fruit.
Other steps and parameter are identical with one of embodiment four to seven.
Embodiment nine：Unlike one of present embodiment and embodiment four to eight：The step 7
The welding angle of middle laser welding is that the center of circle of incident laser and the T-shaped circular side panel 1-1 of axle 1 of planet carrier and the center of circle of circumcircle connect
The angle of line, sin welding angle=0.4d/D, d is central gear (3) diameter.It is critically important to the effect of anti-splashing to weld angle,
Angle it is too big, it is necessary to laser power will be very big, splashing, the too small influence welding effect of angle can be produced.
Other steps and parameter are identical with one of embodiment four to eight.
