Detailed Description
For a better understanding of the present invention, reference will now be made in detail to the present invention, examples of which are illustrated in the accompanying drawings.
The utility model discloses a to the problem that appears in run from opposite directions bull gear use and the manufacturing process to research analysis, thereby the bull gear of a multistage forge welding structure of design. The utility model discloses a bull gear ring indicates major diameter ring gear, and this bull gear ring can comprise 6 ~ 8 sections welded structure's single section ring gear, and it is fixed to close bolted connection through positioning bolt between two adjacent single section ring gears, forms the full circle bull gear ring at last. The big gear ring with the structure overcomes the defects of large blank deformation, more casting defects, large blank allowance, low material strength, low machining precision of the large module gear profile and the like of a large cast gear ring, reduces the manufacturing difficulty of the big gear ring, greatly reduces the manufacturing cost of the big gear ring, and can improve the precision and the strength of the big gear ring.
Example 1:
referring to fig. 1, 2 and 3, the present invention provides a bull gear with a multi-stage forge welding structure. The large gear ring is composed of a plurality of single-section gear rings, and two adjacent single-section gear rings are connected through bolts. Each single-section gear ring comprises an outer ring tooth part 1, a web plate 2, a rib plate 3 and an end face handle plate 6. The outer ring tooth part 1 is welded with the outer side of the web plate 2, the two ends of the web plate 2 are welded with the end face of the plywood 6, and the middle parts of the two sides of the web plate 2 are respectively welded with the rib plates 3 to increase the strength of the gear ring. And analyzing and comparing the structural form of the large gear ring with that of the traditional large gear ring to determine that the structural form of the large gear ring is a welding structural form. And (3) assembling and welding each single-section gear ring by using a mould, and performing postweld heat treatment to ensure the basic size of the single-section gear ring, remove welding stress and avoid the occurrence of warping deformation. When the outer ring tooth part is machined, the expansion deformation of the single-section gear ring caused by large removal amount is required to be considered, and the stabilization or failure treatment is adopted. The sectional size of each single-section gear ring is small, rough machining of each part can be realized by utilizing existing machining equipment in a workshop, machining is carried out after combination is not needed, and after-treatment of rough machining is carried out, the single-section gear rings are ensured not to be expanded and deformed.
