Specific embodiment
Embodiment 1, as shown in Figure 1 and Figure 2, a kind of large fan for recirculated water cooling tower, including：Fan 1, main shaft 2,
Reductor 3, bearing block 4, motor 5, shaft coupling 6, wherein：Fan 1 is connected to the front end of main shaft 2 by shaft coupling 6, and main shaft 2 is worn
Run through the last connection motor 5 of reductor 3 after crossing bearing block 4.Increase axle on the basis of traditional structural electromotor 5 and reductor 3
Bearing 4, bearing block 4 are placed in the forward position of main shaft 2, can play the effect of dissipation of ferees to the main shaft 2 of dean so that right
The huge support force supporting role of fan 1, reduces main shaft 2 for motor 5 and the active force of reductor 3, so as to ensure electricity
Machine 5 and the normal operation of reductor 3, are provided with 1 part of fan of 6 connecting fan of shaft coupling in the front end of main shaft 2, and shaft coupling 6 has
There are buffering, vibration damping and improve shafting dynamic property.
Further, the bearing block 4 includes：Bearing internal layer 7, ball 8, bearing outer layer 9, bearing wall 10, ring water layer 11,
Base 12, water inlet 13, outlet 14, point water cut-off 15, bearing internal layer 7 and bearing outer layer 9 are placed in inside bearing wall 10, bearing
Full ball 8 is filled between internal layer 7 and bearing outer layer 9, forms ring water layer 11, bearing wall 10 between bearing outer layer 9 and bearing wall 10
Lateral wall on offer water inlet 13 and outlet 14, between water inlet 13 and outlet 14 by 15 layering of point water cut-off every
Disconnected, 10 bottom of bearing wall is fixed on base 12.In the work cooled down by high-temperature water, 1 body of fan due to long-time at
In hot environment, temperature is difficult to decline, and high temperature can be transferred on the 5 grade device of motor of 2 end of main shaft with main shaft 2, is passing through
During bearing block 4, the interaction of heat can be equally produced, therefore it provides the bearing block 4 that can lower the temperature, can preferably avoid high temperature
Heat is transmitted by main shaft 2, during use, the water pipe water outlet with water pump is terminated at water inlet 13, is started water pump or sluice,
Cold water enters water inlet 13 from water pipe, and the full ring water layer 11 of filling, cold water flow in ring water layer 11, the lower section of ring water layer 11, axle
