Embodiment Construction
[0025] The present invention will be described in detail below in conjunction with specific embodiments, where the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.
[0026] This embodiment discloses a method for repairing hard-faced gears, comprising the following steps:
[0027] (1) remove the oil stain layer, fatigue layer, and rust spot layer of the damaged part of the hard-faced gear to be repaired;
[0028] Of course, before this, it needs to include routine cleaning→hardness testing→ultrasonic flaw detection (damage degree, area size)→purification treatment→material chemical analysis; clean the damaged part of the hard tooth surface to be repaired with diesel oil to remove tooth surface damage Partial or overall cleaning is the best, depending on the area, space, location, and size of the repair, so as to achieve the purpose of metallurgical bonding; on the gear...

Abstract
The invention relates to a technique for repairing a hardened gear, specifically disclosing a method for repairing a hardened gear, which can be applied to industries such as a cement plant, a steel mill, a missile unit, chemical industry, railway, petroleum, mine, a power plant, a sintering plant, a pelletizing plant, a steel rolling mill, a fertilizer plant and the like. The method is capable of solving repair of a fault thickness within a range of 1-300 mm in a cladding manner by employing different materials for a joint layer, a transition layer, a work layer and a processing layer in this order. Therefore, with the method, the hardened gear can be quickly repaired, so that the economic loss caused by the damage of the hardened gear is minimized.
Description
technical field [0001] The invention relates to a hard-faced gear repair technology, in particular to a hard-faced gear repair method, which can be used in cement plants, steel plants, missile troops, chemicals, railways, petroleum, mines, power plants, sintering plants, and pellets Factories, smelters, refractory plants, rolling mills, ceramic plants and other industries. Background technique [0002] At present, hard-faced gears have broken teeth, wear, pitting and peeling, which cannot be repaired. There is no successful precedent for domestic and foreign scientific research institutes and maintenance units, so they can only be replaced with new hard-faced gears. [0003] Because conventional welding materials, such as basic welding rods, welding wires, acid welding rods, welding wires, and other types of welding materials and technology, cannot be involved in this repair category, the main disadvantages of existing welding materials and processes for welding hard-faced g...
