FIELD: machine building. ^ SUBSTANCE: proposed adjustable differential gear comprises differential mechanism 5 with its input shaft 4 coupled with motor 1 and another shaft 7 coupled with load, and gear ratio adjustment device made up of friction variator. Gear wheel 6 engages via differential mechanism pinion frame with worm shaft 8 and friction variator disc 9. Aforesaid input shaft 4 is engaged via gearing with friction variator second disc 11. Discs 9, 11 are coupled via roller friction gearing with its case 14 coupled with liner displacement drive15. Worm wheel 5 and worm shaft 8 feature helix angle equal to that of friction there between. ^ EFFECT: simplified design, higher efficiency and reliability. ^ 2 cl, 2 dwg |
