ABSTRACT:
The invention relates to gear drives. The globoid worm gearing comprises a cylindrical worm-wheel in mesh with a globoid worm. The side surfaces of the thread of said globoid worm are shaped so as to envelop the side surfaces of the worm-wheel teeth with the result that in the process of successive engagement of the worm thread with the worm-wheel teeth the worm thread makes a linear contact throughout the side surface of the worm-wheel teeth. Said globoidal gearing is capable of transmitting larger torques and possesses a greater kinematic accuracy than like-size modified globoid worm gears known in the prior art.
A method of making the globoid worm is provided whereby the worm is generated through relative movements of the worm blank and a rotary cutter and thereafter the side surfaces of the worm thread are finished by honing. The cutting edges of the rotary cutter are located on a generating surface having the shape of the side surfaces of the cylindrical worm-wheel teeth. The finishing is effected by means of a hone with teeth whose side surfaces are identical with the side surfaces of the cylindrical worm-wheel teeth.
