Driving device for large-specs pulper

The utility model discloses a driving device for a large-specs pulper, which comprises a rotor, a bearing suspension device, a vertical shaft coupling, a standard speed reducer, a water level shaft coupling and a motor; wherein, the bearing suspension device comprises a bearing seat, a bearing and a spindle; the bearing suspension device is provided between the rotor and the standard speed reducer, which avoids the attack to the speed reducer spindle during the working process of the pulper; the durability of the speed reducer is better lengthened. The bearing suspension device is connected with the standard speed reducer through the vertical shaft coupling; because the advantages of the adopting the standard speed reducer are good reliability and low cost, the expenses of the investment and the operational maintenance of the users are reduced greatly. The critical piece of the driving device for large-specs pulper of the utility model adopts standard parts, which alters the problem of the adopting the nonstandard equipment of the present technique; the entire quality is enhanced, the expenses are reduced greatly, and the operation of the entire equipment is reliable.
