SprocketHow to choose a reasonable heating method?

It is very important to choose a reasonable heating method according to the shape and distortion trend of the sprocket.When heating gears of different shapes, sizes and materials, necessary measures should be taken as far as possible to reduce the distortion during the heating process.Generally, for workpieces with large cross-section sizes, in order to prevent the parts with small cross-sections from overheating, sometimes the workpieces are lifted out of the furnace during the heating process, and then heated after a little air cooling. The purpose is to make the internal and external temperatures of the workpieces close to the same. The method is called discontinuous heating method.For thin and slender gears, when the salt bath furnace is heated, the salt bath rolls will cause the gear to be twisted. For this, the heating temperature can be increased by 30 ~ 50C, and the sprocket is placed in the furnace for static heating In order to ensure the uniform heating of each part, the ring gear is heated by rapid rotation. Generally, the sprocket teeth are heated and the whole is cooled to reduce distortion.
