specific Embodiment approach 1

[0036] Specific implementation mode one: as figure 1 and figure 2 As shown, a split planetary carrier includes a planetary carrier T-shaped shaft 1 and a planetary carrier P-shaped bracket 2;

[0037] Planet carrier T-shaft (such as image 3 Shown) 1 is made of circular side plate 1-1 and axle sleeve 1-2 two parts, and described circular side plate (as Figure 4 and Figure 11 Shown) 1-1 has sun gear hole 1-3, four planetary gear holes 1-4 and four recessed parts 1-5, and sun gear hole 1-3 is positioned at the center of circular side plate 1-1, and the sun Four planetary gear holes 1-4 are evenly distributed around the gear hole 1-3, four depressions 1-5 are uniformly arranged on the edge of the circular side plate 1-1, the planetary gear hole 1-4 and the depression 1-5 Arranged in a staggered order, the sun gear hole 1-3 and the shaft sleeve 1-2 are arranged concentrically;

[0038] Such as Figure 5 As shown, the planet carrier P-type bracket 2 is a disc body structur...

specific Embodiment approach 2

[0039] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the split planetary carrier also includes a sun gear 3; Inside the bushing 1-2 of shaft 1.

[0040] Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0041] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the split planetary carrier also includes a driving gear 4 connected to the driving gear hole of the P-shaped bracket 2 of the planetary carrier.

[0042] Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention discloses a welding spattering-preventing method for a split planet carrier. The welding spattering-preventing method aims to solve the problems that existing planet carriers are high in machining cost and low in machining efficiency, machining by automatic production lines cannot be realized and spattering generated in the laser welding process of the split planet carrier influences the cleanliness and the assembly accuracy of parts. According to the method, German imported equipment and a turning-milling combined double-main shaft and double-turret structure are adopted, and machining can be completely completed through clamping at a time; the advanced laser welding mode is adopted after the parts are assembled according to the split machining method. According to the method, a spattering-preventing structure and a secondary spattering-preventing structure are designed, the problem that the cleanliness and the assembly accuracy of assembly surfaces are influenced after laser through welding is solved, the efficiency is improved, 13 parts are reduced for assembly components, the material is saved by 35%, the assembly cost is reduced, and machining by the automatic production lines is realized. The welding spattering-preventing method is applied to the field of material machining.

Description

technical field [0001] The invention relates to a spatter prevention method for split planet carrier welding. Background technique [0002] Planetary gear reduction has compact structure, light weight, large load capacity and high transmission efficiency, and is widely used in various reduction mechanisms. Automobile automatic transmissions have special requirements for reduction mechanisms such as light weight, high transmission efficiency and compact structure. Key components of automotive automatic transmissions. At present, a large number of planetary gear reduction mechanisms are used in automobile automatic transmissions, reaching one to four sets [0003] At present, when the overall structure is mainly adopted in China, the early development and small batch production of automatic transmissions have cost advantages. However, when production volumes increase significantly, our cost advantage disappears. And this technology is basically monopolized by foreign manufa...
