But sliding bearing is the aligning seat sliding bearing.
But the aligning seat sliding bearing comprises: but but but but cover, first aligning seat, second aligning seat in the aligning seat sliding bearing overcoat aligning seat sliding bearing, but but in aligning seat sliding bearing overcoat and the aligning seat sliding bearing cover be with split; Connect fastening through bolt; But aligning seat sliding bearing overcoat cooperates assembling to be connected with electric motor end cap; But cover is connected with the axle journal position of rotor in the aligning seat sliding bearing.
Have the adjustment pad upright the branch between the face.
But but aligning seat sliding bearing overcoat and aligning seat sliding bearing inner surface of inner race babbitting.
But but adopt inside and outside spherical surface to cooperate in aligning seat sliding bearing overcoat and the aligning seat sliding bearing between the cover.
But but between the cover pin is arranged in aligning seat sliding bearing overcoat and the aligning seat sliding bearing.
Non-output shaft one end of adjustable frequency motor is fixed with fan.
The utility model has the advantages that; Because the rotor of adjustable frequency motor is connected with the sliding bearing axle of right ends; But sliding bearing has adopted the aligning seat sliding bearing, on base, is fixed with oil pump, and the feeding and return line road is arranged in the electric motor end cap; Oil pump communicates with oil sealing through pipeline; Fuel feeding point and oil return point is arranged on the end cap of adjustable frequency motor, force in oil sealing, to provide force feed oil, forced feed lubrication by oil pump.Guarantee that within 50KW～300KW scope, the adjustable frequency motor rotating speed is 4000rpm～6000rpm.
Below in conjunction with the embodiment accompanying drawing the utility model is described further:
