Method and apparatus for hot rolling of bevel gears

摘要

A method for hot rolling of bevel gears by infeeding a rotating gear rolling die having a synchronizing member into a rotating work gear having a synchronizing member. First, the teeth of the synchronizing members are brought into engagement, and then rough forming of teeth on the work gear takes place under the action of the teeth of the gear rolling die, wherein the synchronizing member of the work gear is acting as the driving member, and finish rolling of the rolled teeth of the work gear takes place, with the rotating gear rolling die acting as the driving member. An apparatus for carrying out the above method for hot rolling of bevel gears includes a work gear spindle having its power rotation drive and a gear rolling die spindle having power drives for its rotation and axial movement, the spindles being installed in the bed at an angle with respect to each other. There is also provided a power distribution unit connected to the power drives for rotating the gear rolling die spindle and work gear spindle, respectively.
