Alternating current asynchronous motor damping device for wind power variable pitch

Abstract

The alternating current asynchronous motor damping device comprises a box body, symmetrically distributed sliding grooves are formed in the bottoms of the inner walls of the two sides of the box body, pulleys are slidably connected to the inner walls of the sliding grooves, a fixing rod is welded to the outer wall of one side of each pulley, and a first fixing plate is welded to the outer wall of one side of each fixing rod; first damping springs distributed at equal intervals are welded to the outer wall of the top of the first fixing plate, a placing plate is welded to the outer walls of the tops of the first damping springs, and threaded rods distributed symmetrically are installed on the outer wall of the top of the box body. When the motor works, loud noise and vibration sense can be generated, the noise generated when the motor works can be effectively reduced through the sound insulation layer arranged on the inner layer of the box body, and the motor can be quickly assembled and disassembled through sliding connection between the pulleys and the sliding grooves; and vibration generated when the motor works can be effectively reduced through the first damping spring and the second damping spring.

Description

technical field [0001] The invention relates to the technical field of motor vibration reduction, in particular to an AC asynchronous motor vibration reduction device for wind power variable pitch. Background technique [0002] In recent years, high speed has become the development direction of electric motors, which are mostly used for direct drive of high-speed loads such as compressors and water pumps. With the continuous increase of motor speed, the vibration problem caused by this has become increasingly prominent. The use of elastic vibration isolation measures between the motor and the base can effectively improve the vibration index of the motor, but such a vibration reduction effect is not very good, and the motor will generate a lot of noise during use and affect the environment. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to propose an AC asynchronous motor vibration damping device for wind power variable pitch in order to solve the...

[0002] In recent years, high speed has become the development direction of motors, which are mostly used for direct drive of high-speed loads such as compressors and water pumps. As the speed of motors continues to increase, the resulting vibration problems have become increasingly prominent. In order to eliminate motor vibration, the stator Using elastic vibration isolation measures between the base and the motor can effectively improve the vibration index of the motor, but the vibration reduction effect is not very good, and the motor will generate a lot of noise during use and affect the environment
