Embodiment 1

[0037] Such as Figure 1~3 As shown, this embodiment relates to a welding structure of gears and coupling teeth, including: an annular shift gear 1 with a gear portion and an engaging portion, and an annular coupling tooth 2 with a gear portion and a press-fit portion, wherein: the shift gear 1 The joint part b of the joint tooth 2 is an interference fit with the press-fit part a of the coupling tooth 2.

[0038] Such as Figure 4 As shown, the first annular groove 4 is provided on the joint part b of the gear gear 1, and the second annular groove 5 is provided on the press-fit part a of the coupling tooth 2. After the interference fit, the first annular groove The groove 4 and the second annular groove 5 form a first cavity.

[0039] The interference fit refers to: the joint part of the ring gear 1 and the ring coupling tooth 2 and the end face of the press-fit part are flush and form a ring-shaped junction, when laser welding or electron beam welding is performed to weld t...

Abstract

The invention provides an optimization welding method for a gear and a conjunction gear, and belongs to the field of transmission manufacturing. The inner side of the to-be-welded position of the matched surface of the shifting gear and the conjunction gear is sequentially provided with a first cavity for reducing the grinding area of the matched surface and a second cavity communicated with the first cavity. The second cavity is communicated with the opposite side of the to-be-welded position of the matched surface, and then exhausting in the welding process is achieved. The requirements for assembly accuracy of a part are met, machining cost is reduced, finally the effects that the welding position is evenly stressed and welding stability is high after welding is finished are achieved, a formed welding joint is located on the outer side of the end face of the part, and welding work and the quality inspection of the welding position are facilitated.

Description

technical field [0001] The invention relates to a technology in the field of transmission manufacturing, in particular to an optimized welding method and structure of gears and coupling teeth. Background technique [0002] As the core component of the automobile transmission, the welding structure of the shift gear and the coupling teeth directly affects the shift performance of the transmission. The currently disclosed welding structure involving shift gears and coupling teeth has many defects, such as uneven force on the welding point; high-temperature air formed by welding melts into the weld seam to form bubbles, which affects the welding strength; unreasonable welding structure causes welding The operation is difficult, the quality inspection of the welding part is difficult; the welding assembly accuracy is not high, etc. Therefore, designing a good welding structure of gears and coupling teeth can greatly improve the working performance of the automobile transmission...
