FAQ

1. How to measure the runout tolerance of motor products?
   Motor products are typical rotating equipment. During the running process with load, when the rotor rotates, the equipment needs to be driven by the shaft extension to rotate. In order to ensure the coaxiality requirements of the motor itself and the operation of the driving equipment, there are tolerance control requirements for radial runout and end face runout for some parts of the motor.
   For the complete product of any installation method, the radial runout control of the shaft extension is very critical, and for the B35 motor, the radial runout of the flange end cover lip and the end face runout of the lip plane are also added.
    
   For motors with additional devices such as encoders and overspeed switches installed on the rotor, it is also necessary to fix the terminal shaft on the non-transmission end of the motor shaft. After the assembly is completed, the terminal shaft should be coaxial with the main shaft of the motor. Shaft radial runout detection method to determine whether it meets the requirements.
    
    
   The detection of circular runout and plane runout is carried out with a dial indicator or dial indicator with a magnetic base. During the detection process, the magnetic base should be firmly fixed to avoid the distortion of the detection data caused by the weak fixation.
    
   Introduction to the knowledge of dial indicator for detection
    
   The dial indicator was made in 1890 by B.C. Ames in the United States. Commonly used for shape and position errors and length measurement of small displacements. The dial of the dial indicator is printed with 100 equal division scales, that is, each division value is equivalent to moving the measuring rod by 0.01 mm. If 1000 equal division scales are printed on the circular dial, each division value is 0.001 mm, and this measuring tool is called a dial indicator.
    
    
   By changing the shape of the probe and matching with the corresponding bracket, it can be made into deformed varieties of dial indicators, such as thickness dial indicators, depth dial indicators and inner diameter dial indicators. If a lever is used instead of a rack, a lever dial indicator and a lever dial indicator can be made, which have a small range of indications but high sensitivity. In addition, their probes can be rotated within a certain angle, which can adapt to measurement in different directions and have a compact structure. They are suitable for measuring the shape and position errors of outer circles, small holes and grooves that are difficult to measure with ordinary dial indicators.
    
    
   The layout of the dial indicator is relatively simple, the transmission mechanism is a gear train, the outline size is small, the weight is light, the transmission mechanism is small, the transmission is relatively large, the circumference scale can be used, and it has a large measurement scale, which can not only be used for comparative measurement. , can also be measured for sure.
    
   The working principle of the dial indicator is to move the measuring rod caused by the measured scale in a small straight line, expand it through gear transmission, and change it into the change of the indicator on the dial, and then read the size of the measured scale.
    
   The main application of the dial indicator
    
   A very important application of a dial indicator is to measure mechanical measurements such as shape and position errors, such as roundness, circular runout, flatness, parallelism, straightness, etc. Using a dial indicator to measure mechanical shape and position errors has a A very simple and efficient method is to directly use our data analyzer to connect the dial indicator to measure without manual reading. The data analyzer software can collect and analyze the dial indicator data, and calculate the measurement results. , which can greatly improve the measurement efficiency.
    
    
   Precautions for using the dial indicator
    
   (1) Before use, check the flexibility of the movement of the measuring rod. That is, when the measuring rod is gently pushed, the movement of the measuring rod in the sleeve should be flexible, without any jamming phenomenon, and the pointer can return to the original scale position every time the hand is released.
    
   (2) When using, the dial indicator must be fixed on a reliable clamping frame. Do not try to save trouble, and simply clamp it in an unstable place, otherwise it will easily cause inaccurate measurement results or break the dial indicator.
    
    
   (3) When measuring, do not make the stroke of the measuring rod exceed its measuring range, do not make the meter head suddenly hit the workpiece, and do not use a dial indicator to measure the surface roughness or work with significant unevenness.
    
   (4) When measuring the plane, the measuring rod of the dial indicator should be perpendicular to the plane. When measuring the cylindrical workpiece, the measuring rod should be perpendicular to the center line of the workpiece, otherwise, the measuring rod will be inactive or the measurement results will be inaccurate.
    
   (5) For the convenience of reading, generally let the large pointer point to the zero position of the dial before measurement.
