Tilting-pad bearing built-in motor

Abstract

The invention discloses a tilting-pad bearing built-in motor comprising a motor box, a motor spindle, a front end cover assembly, a rear end cover assembly, a motor stator and a motor rotor, wherein the motor rotor is sleeved on the motor spindle; the motor stator is sleeved in the motor box; the motor spindle is arranged in the motor stator; two ends of the motor stator are both provided with sealing plates sleeved outside the motor spindle and fixedly connected with the motor box and the motor stator; the front end cover assembly comprises a front flange and a front tilting-pad bearing supported between the front flange and the motor spindle, wherein the front flange is fixed at the front end of the motor box; and the rear end cover assembly comprises a rear flange and a rear tilting-pad bearing supported between the rear flange and the motor spindle, wherein the rear flange is fixed at the rear end of the motor box. The tilting-pad bearing built-in motor has the advantages of simple and compact structure, short axial span and high critical speed of shafting.

Description

technical field

[0001] The invention relates to the field of mechanical manufacturing, in particular to a high-power high-speed motor supported by a tilting pad bearing. Background technique

[0002] Large-scale high-speed and high-power rotating machinery equipment is widely used in national defense, metallurgy, mining, chemical industry and other fields, such as various large fans, turbine compressors, ship power systems and centrifugal compressors. Large-scale high-speed rotating machinery and equipment occupy an extremely important position in my country's national economy.

[0003] Traditional high-speed and high-power rotating mechanical equipment mostly uses transmission systems (belt drives, gearbox drives, etc.) to achieve speed increase, and the power source is mostly ordinary motors. Rotating mechanical equipment using this type of transmission mode allows a lower maximum operating speed. Due to the complexity of the transmission system, the vibration and noise a...
