Problems solved by technology

[0003] In the actual use process, due to the relatively harsh working conditions and the design flaws of the transmission parts in the factory-configured reduction box, the large radial clearance of the designed main shaft bearing causes the fan spiral to vibrate, and the fan spiral blades and rotor Vibration cracking and fracture accidents at the drum connection; and the frequent oil leakage of the gland under the main shaft bearing at the bottom of the original gearbox, which affects the safe and normal operation of the cooling tower and increases the workload and cost of equipment maintenance

Abstract

The invention discloses a transmission device of a reduction gearbox of a hollow cooling tower. The transmission device comprises a gearbox. A vertically-arranged draught fan main shaft is installed in the gearbox. The lower end of the draught fan main shaft extends out of the gearbox. The upper portion and the lower portion of the draught fan main shaft are sleeved with a first main shaft bearing and a second main shaft bearing respectively. The first main shaft bearing and the second main shaft bearing are located in an upper installation hole and a lower installation hole of the gearbox respectively. The portion, extending out of the gearbox, of the draught fan main shaft is sleeved with a lower bearing gland. The lower portion of the draught fan main shaft is further sleeved with a third main shaft bearing. The third main shaft bearing is located in the lower installation hole of the gearbox and located between the second main shaft bearing and the lower bearing gland. The lower portion of the draught fan main shaft is further sleeved with a bearing space ring clamped between the third main shaft bearing and the second main shaft bearing. The transmission device of the reduction gearbox of the hollow cooling tower is simple in structure, convenient to maintain and capable of guaranteeing safe and normal running of the cooling tower.

Description

technical field [0001] The invention relates to a transmission device, in particular to a transmission device for a reduction box of a hollow cooling tower. Background technique [0002] At present, the hollow cooling tower used in our country is used to exchange heat and cold after water and air flow contact to generate steam. The waste heat generated in the air conditioner is used to reduce the water temperature of the evaporative cooling device to ensure the normal operation of the system. [0003] In the actual use process, due to the relatively harsh working conditions and the design flaws of the transmission parts in the factory-configured reduction box, the large radial clearance of the designed main shaft bearing causes the fan spiral to vibrate, and the fan spiral blades and rotor Vibration cracking and fracture accidents at the drum connection; and the frequent oil leakage of the gland under the main shaft bearing at the bottom of the original gearbox, which affec...
