A reversing worm gearing has worm wheel. Two kinematically connected to each other with toothed gearing worms one of which is drive one, and the other one is driven, with same screw surface of given profile of teeth that go into engagement with teeth of worm wheel and drive output shaft of which is connected to drive worm and transfers rotary motion to it, it is arranged as reversing electric motor. The dive and driven worms of worm gearing are placed in opposite in diameter positions with respect to worm wheel in parallel to each other. At that toothed gearing that connects those is arranged as pair of cylinder toothed wheels, it consists of opinion and driven toothed wheel. The shaft of driven toothed wheel is connected to driven worm through clutch that is arranged with possibility of counter axial turn of driven worm and driven toothed wheel in opposite directions and fixation of those in given positions. |
