Abstract

The invention relates to a submerged-arc welding tubular welding wire used for idle gear remanufacturing. The wire comprises the following components of, by mass, 1-1.5% of nickel base alloy powder, 3-3.7% of electrolytic manganese powder, 2-2.6% of silicon carbide, 3-4% of ferrovanadium powder, 0.5-0.9% of rare earth metal powder and the balance water atomization method iron powder. The submerged-arc welding tubular welding wire provided by the invention is reasonable in component matching, a welding layer is formed on the surface of an idle gear in a welding mode, and accordingly abraded dimension repair is achieved; and in addition, the formed welding layer can further improve the surface quality of the idle gear, and accordingly the service life of the idle gear is prolonged. The submerged-arc welding tubular welding wire has excellent surfacing process performance, a surfacing layer has plasticity, tenacity and impact resistance and is good in metal resistance-metal abrasion resistance, and multi-layer surfacing can be achieved, namely, the surfacing layer can serve as a roller repair transition layer as well as an abrasion resistant layer.

Description

technical field [0001] The invention relates to the technical field of remanufacturing, in particular to submerged arc welding tubular welding wire for idler remanufacturing. Background technique [0002] The idler gear refers to the gear that plays a transmission role between two transmission gears that do not contact each other, and meshes with these two gears at the same time to change the rotation direction of the driven gear to make it the same as the driving gear. Its function is only to change the steering and The transmission ratio cannot be changed. [0003] During the working process, the idler will wear and tear. Over time, it will cause problems in motion transmission. Therefore, it is necessary to replace the idler in time. This method has high maintenance costs, and the worn idler is not recovered. Therefore, there is an urgent need for a method that can recycle idler wheels. Contents of the invention [0004] In order to solve the deficiencies in the prior...
