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 invention relates to an annular motor. A large-scale annular motor rotor electrode block adjusting method comprises the steps of fixing dial indicators on an extension bracket of a motor stator, enabling the head of each dial indicator to be supported on the surface of each rotor electrode block, rotating a rotor and enabling each dial indicator to slide to a next rotor electrode block smoothly and steadily through a gap between two rotor electrode blocks by using a transition block; recording the reading of each electrode block and calculating to obtain a theoretical excircle radian; respectively fixing two dial indicators on two rotor electrode blocks which are adjacent to one rotor electrode block needing adjustment, enabling the heads of the dial indictors to be supported on the rotor electrode blocks and returning each indicator needle to zero; respectively placing two jacks at two sides of the downside of the rotor electrode block, lifting the jacks after fixing bolts are loosed and locking two fixing bolts after the readings of the dial indicators reach to a pre-calculation value; loosing the jacks and watching the readings of the dial indicators, and fastening the other two bolts if no change happens. According to the large-scale annular motor rotor electrode block adjusting method, one-time measurement, one-time adjustment and one-time reexamination are basically achieved.

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...
