Sprocket gear quenching equipment

Abstract

The invention relates to the technical field of gear processing and discloses sprocket gear quenching equipment. The equipment comprises a tank body in which cooling oil is added, and a heater, wherein a driving device is fixedly arranged at the bottom end of one side of the tank body; a sleeve provided with bosses on both sides is fixedly connected with the center of the bottom of the inner wallof the tank body; and groove rotating shafts are arranged at both sides, which are rotatably connected with a top end through two bearings, of both ends in the sleeve. The sprocket gear quenching equipment has the beneficial effects that through the cooperation of the rotating shafts, support plates, support frames and rotating wheels, object stages can be rotated; meanwhile, by utilizing a heater, the rotating shafts, a rotating disc, limiting cylinders and a driving wheel, a heat-treated gear can be cooled below the cooling oil level through the rotation of the rotating shafts and the othergears can be rotated to the position where the heater is arranged to be heated at the same time; and therefore, the other gears are heated while the gear is cooled at the same time, so that the gear can be conveniently quenched by the equipment and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of gear processing, in particular to a sprocket gear quenching equipment. Background technique [0002] The purpose of sprocket gear quenching is to transform supercooled austenite into martensite or bainite to obtain martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly increase the strength, hardness, Wear resistance, fatigue strength and toughness, etc., so as to meet the different requirements of various mechanical parts and tools. The principle of gear quenching is to put the workpiece into the inductor (coil) and heat the gear. The existing partial quenching equipment The middle stage is integrated. When the gear is quenched, the stage needs to be lowered into the cooling oil to cool down. At this time, since the stage moves below the level of the cooling oil, the heater cannot heat other gears, resulting in Efficiency is slower. Contents of the inve...
