Drum-shaped filter screen parallel shaft driving device

The invention relates to a drum-shaped filter screen parallel shaft driving device which comprises a horizontally-arranged driving shaft, two first bearings are evenly installed on the driving shaft, bearing seats are arranged on the two first bearings, and a driving mechanism is arranged on the driving shaft; the driving mechanism comprises a speed reducer, the output end of the speed reducer is connected with one end of a driving shaft, three input ends are arranged on the speed reducer, and a medium-high speed motor and two low-speed motors are connected to the three input ends respectively. The medium-speed motor and the two low-speed motors are connected with the speed reducer through the three plum-blossom-shaped elastic couplings respectively, and the driving shaft is connected with the speed reducer through the serpentine spring coupler. According to the parallel shaft driving device for the drum-shaped filter screen, non-stop switching of low speed, medium speed and high speed under different working
