Embodiment

[0016] Example: A method for controlling carburizing and quenching deformation of a thin-spoke large-diameter cylindrical gear

[0017] Such as figure 1 As shown, the cylindrical gear in this embodiment is a spur gear 1, the outer diameter D of the gear is between 1.2 and 1.7 meters, and the thickness S of the web 2 is between 150 and 250 mm.

[0018] Such as figure 2 As shown, for this thin-spoke large-diameter spur gear 1, before the start of carburizing and quenching, the aluminum silicate fiber material 4 is used to fill the corresponding recesses 3 on both sides of the web 2 of the cylindrical gear 1, and A steel plate 5 is provided at both ends of the cylindrical gear 1, and the two steel plates 5 are used to clamp and compress the aluminum silicate fiber material 4 covering both sides of the spoke plate 2 of the cylindrical gear 1 to protect the spoke plate 2 of the cylindrical gear 1 Part; then the cylindrical gear 1 is carburized and quenched according to the drawings or ...

Abstract

The invention provides a control method for the carburizing, quenching and deformation of a thin wheel disk type large-diameter cylindrical gear. The method is characterized in that before the carburizing and quenching start, concave parts which correspond to two sides of the wheel disk of the cylindrical gear are filled by an aluminum silicate fiber material, the wheel disk of the cylindrical gear is thermally protected by means of clamping and pressing of a steel plate, the temperature change speed of each part is cushioned, and the temperature error of each part is evened, so that the problem that the gear is seriously deformed due to inconsistent heating speed and cooling speed of parts can be reduced.

Description

Technical field [0001] The invention relates to a heat treatment process of gears, in particular to a control method for reducing the deformation of thin-spoke large-diameter cylindrical gears during carburizing and quenching. Background technique [0002] Such as figure 1 As shown, the thin-spoke large-diameter cylindrical gear refers to a cylindrical gear with a diameter D greater than 1.2 meters, and the ratio of the web thickness S to the diameter D is less than or equal to 0.2. This kind of gear has a wide range of uses in medium and large mechanical equipment. From the perspective of the processing flow, the manufacture of gears requires a heat treatment process of carburizing and quenching to improve the strength of the gear teeth and mechanical properties such as surface wear resistance. The carburizing and quenching process is usually arranged in the later stage of the gear production process. For thin-spoke large-diameter cylindrical gears, due to the special shape and...
