FIELD: machine building.SUBSTANCE: gearing 10 comprises axle gear 14 that makes end worm gear with, at least, one worm tooth and worm drive gear 12 to engage with axle gear 14. Worm drive gear 12 can have, at least, one worm tooth with vertex angle smaller than 20 degrees. Invention covers also the differential gear. Differential gear comprises housing 64 and gearing 10. Besides, differential gear may incorporate torque transmitting ring 18 that allows drive worm gear 12 to rest thereon.EFFECT: possibility to use enlarged quantity of drive gears or larger-diameter drive gears, higher-strength drive worm gears.20 cl, 15 dwg |
