Embodiment Construction

[0019] The technical contents of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] The surface quenching of the gear tooth surface must adopt the continuous quenching method. For spur gears, the quenching equipment only needs to have the function of moving along the tooth surface. For the continuous quenching of helical gears, not only does the quenching equipment have the function of moving along the tooth surface, but also the gear needs to make circular motion along the axis. The speeds of the two must cooperate with each other to realize the quenching of the tooth surface.

[0021] The invention adds a device to the original quenching equipment, and the device can realize the circular motion of the helical gear along the axis.

[0022] The specific technical scheme is as follows:

[0023] A method for quenching the tooth surface of a large helical gear. The method adopts a movable medium-frequency power supply...

Abstract

The invention relates to a surface hardening method for the tooth surface of a large-sized bevel wheel. In the method, a movable medium-frequency power supply hardening machine head is fixed on a vertical frequency control power slipway to realize the axial movement of the bevel wheel; the bevel wheel is hoisted through a wire cable by a hook of a crown block, and is suspended at a proper position suitable for hardening; and the hardening machine head is provided with a frock piece that is matched with the tooth form of the bevel wheel in size, when the vertical frequency control power slipway moves, the frock piece and an inductor synchronously move along with the vertical frequency control power slipway, and when the frock piece moves axially along with the vertical frequency control power slipway, the bevel wheel is rotated. The method is particularly suitable for the hardening of the large-sized bevel wheel, has simple operation and low cost, and can meet the requirement of the hardening.

Description

technical field [0001] The invention relates to a method for quenching the tooth surface of a helical gear, in particular to a method for quenching the surface of a tooth surface of a large helical gear. Background technique [0002] The large helical gear is an important part of the large reducer, and its tooth surface hardness directly affects the service life of the entire reducer, which in turn affects the safety of some large equipment. Therefore, the surface quenching of large helical gears is one of the key technologies in the manufacture of large reducers. [0003] At present, special quenching equipment is generally used in China to quench the surface of helical gears, and some large helical gears cannot be quenched on the surface when their specifications and weight exceed the capacity of special quenching equipment. Contents of the invention [0004] The purpose of the present invention is to provide a method for quenching the tooth surface of large helical gea...
