FIELD: mechanical engineering. SUBSTANCE: reversing is provided by changing positions of driving and driven gear clusters. Driving member consists of two bevel gears interconnected by cylindrical portion on which two screw grooves are cut changing from left-start into right-start and from right-start into left-start portions with provision of axial displacement. Intermediate member has two bevel gears and end face spherical segment with loop-shaped tooth. Intermediate shaft has joint arranged on axis of driven shaft to provide running of driven member bevel gear over driven gear. EFFECT: enlarged operating capabilities. 6 cl, 5 dwg |
