  • Patent number: 4047449
    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.
