Abstract
In a process of hardening wheel teeth by means of a flame which heats the bearing surfaces of the teeth more than their end surfaces, the wheel is moved past the burner or burners continuously or intermittently at such a relatively high speed that each tooth is subjected repeatedly to the action of the flame, the wheel being subsequently quenched. The end surfaces of the teeth may be protected by means of a paste such as a mixture of asbestos and water glass, and the heads of the teeth may be arranged to come into contact with a cooling liquid during rotation of the wheel. An elongated flame may be used in order to heat the spaces between the teeth more than the heads of the teeth. When the rotation of the wheel is intermittent, the flame may rest in the spaces between the teeth for a longer time than on the end surfaces of the teeth. The heated teeth may be quenched by liquid applied to the face or periphery of the wheel, particularly into the spaces between the teeth, for example from a ring-shaped pipe concentric with the wheel.
