DEVICE FOR GEAR-CHANGING IN REVERSING DRIVING SHAFT KEEPING DIRECTION OF ROTATION OF DRIVEN SHAFT CONSTANT

摘要

FIELD: mechanical engineering. SUBSTANCE: two driven shafts form two pairs of shafts with first two shafts. The shafts are coaxial in each pair. Main and additional bevel gearing connect the driving shaft to the driven shaft and are forth-linked to provide main gears form two pairs of main gears. The main gears in each pair are coaxially to each other to transmit rotation to the driven shafts. Intermediate gears are mounted on the driving shaft by the means of free running mechanism to be wedged in opposite direction. Intermediate gears have wide teeth for simultaneous engaging two pairs of main gears. EFFECT: simplified design. 1 dwg
