TH26501B - Gear motor drives electric crane Two-speed, with two motors per gear - Google Patents

Abstract

DC60 gear motor drives electric crane with two speed. By using two motors per gear, one without a low-speed reduction gearbox consists of a low-speed motor and High speed Attaches to gears on both sides With the rotor shafts of both speed motors fitted to the same pig spur shaft But on different sides The gear motor drives the electric crane with two speed. It uses two motors per gear, one with a low-speed reduction gearbox consisting of a low-speed motor attached to a low-speed reduction gearbox. And low speed gear reducer Attached to the gear on one side, the high speed motor. Attaches to the other side of the gear By the rotor shaft of the high speed motor and the low speed gear reducer Use the same pig spur shaft. But on different sides The gear motor drives the electric crane with two speed. By using two motors per gear, one without a low-speed reduction gearbox consists of low-speed and high-speed motors attached to the gears on both sides. By the rotor shaft of the motor at both speeds Put on the same pig spur shaft But on different sides The gear motor drives the electric crane with two speed. By using two motors per gear, one with a low speed gearbox consisting of a low speed motor. Attached to the reduction gear Low speed And low speed gear reducer Attaches to gear on one side The high speed motor Attaches to the other side of the gear By the rotor shaft of the high speed motor With a low speed gearbox using the same pig spur shaft But on different sides
