Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing:

[0013] Such as figure 1 , figure 2 As shown, the present invention relates to a large-scale welded gear, including a tooth unit 1, a tooth 2, a welding spot 3, a central hole 4, and a positioning hole 5, and is characterized in that the large-scale gear has a plurality of tooth units 1 with evenly distributed welding spots 3. Composed of welding and welding, each tooth unit 1 is formed by casting, and after heat treatment and transfer processing, it is welded into one body after being positioned by the center hole 4 and the positioning hole 5. Tooth unit 1 is cast from 42GrMo. The tooth monomer 1 is heated to 850°-860° in a heat treatment furnace, then kept warm for 5 hours, and then released to air cooling. The tooth monomer is finished by processing such processes as tooth 2, center hole 4, and positioning hole 5.

[0014] When the present invention is used, each sin...

Abstract

The invention relates to a large gear composed of single gear bodies, teeth, welding points, center holes and positioning holes. The large gear is characterized in that the large gear is formed in the manner that the welding points are evenly distributed on the single gear bodies and welded; each single gear body is composed of one center hole and the positioning holes and formed through casting of 42GrMo materials; and integral welding is achieved through positioning of the center holes and the positioning holes after thermal treatment machining. The large gear has the beneficial effects of being large in density, high in tenacity, simple in structure, easy to weld and the like, and the reliability and using safety of the gear are improved.

Description

technical field [0001] The invention relates to an industrial component, in particular a large gear. Background technique [0002] As we all know, at present, large-scale gears used in industries such as firepower and wind turbines are large in size and heavy in weight, requiring a large investment in equipment, which is not conducive to large-scale popularization, low production efficiency, high scrap rate, and high risk. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a large-scale gear with the advantages of high density, strong toughness, simple structure and easy welding. [0004] The technical scheme adopted by the present invention to solve the above-mentioned technical problems is: a large-scale gear, which is composed of a single tooth, a tooth, a welding spot, a central hole, and a positioning hole. Composed of spot welding, each single too...
