Embodiment Construction

[0012] A method for adjusting the rotor electrode block of a large ring motor. The adjustment is carried out after all the rotor electrode blocks are installed, and the overall gauge circle is detected; The head rests on the surface of the rotor block. When the dial indicator encounters the gap between two rotor blocks, use the transition slider to slide the dial indicator head smoothly and steadily to the next rotor pole piece. Rotate the cylinder of the ball mill, record the reading of each rotor block, calculate according to the measured value and the drawing value, and obtain the outer arc of the theoretical rotor block. The calculation method of the outer arc is the sum of the measured values ​​of the two positions of each rotor pole piece divided by the total measured position. Calculate according to the size requirements of the drawing and the value of the dial indicator on the transition slider, and then add the previously calculated value and divide by two to obtain ...

Abstract

The present invention relates to ring motors. A method for adjusting the rotor electrode block of a large ring motor, which includes: using a dial indicator to be fixed on the extension bracket of the motor stator, the head of the meter is placed on the surface of the rotor electrode block, rotating the rotor and using a transition block to allow the dial indicator to pass through the two sides smoothly. Slide the gap between two rotor pole pieces to the next rotor pole piece; record the readings of each pole piece, and calculate the theoretical outer arc; use two dial gauges to be fixed on the adjacent rotor pole pieces that need to be adjusted. On the two rotor electrode blocks, the dial indicator head is placed on the rotor electrode block, and the pointer is reset to zero; two jacks are respectively placed on both sides below the rotor electrode block, and the jack is lifted after the fixing bolt is loosened. After the sub-meter reading reaches the pre-calculated value, tighten the two fixing bolts; loosen the jack to observe the dial indicator reading, and if there is no change, tighten the other two bolts. The present invention basically achieves one measurement, one adjustment and one review.

Description

technical field [0001] The invention relates to a ring motor, in particular to a method for adjusting the rotor of the ring motor. Background technique [0002] Large ring motor is a new type of motor. Its rotor is composed of electrical electrode blocks and mechanical cylindrical equipment. The electrode blocks are distributed to the site. The rotor of a motor is usually divided into dozens of electrode blocks, and each block has 4 to 6 groups. winding. [0003] The rotor electrode block generally adopts the traditional adjustment method, which is to adjust the readings of the dial gauges on both sides of each rotor electrode block to one to one. Then make 2 or 3 adjustments according to the reading of each block until the installation requirements are met. This approach requires back and forth measurement adjustments. This method is labor-intensive, time-consuming, and has poor accuracy. Contents of the invention [0004] The invention aims to overcome the defects of...
