technical field

The invention relates to the technical field of a motor shaft tooth runout inspection tool, in particular to a motor shaft tooth runout inspection tool.

Background technique

The motor shaft tooth is the gear on the rotating shaft of the generator, which is generally a linear gear. To detect the beating amplitude of the motor shaft tooth is to detect the stability of the motor shaft when it rotates at a high speed. The traditional detection method is to use a dial indicator to rotate at a constant speed. After the gear is installed on the shaft, the contact measures the swing amplitude of the rotating shaft. This method can only be measured once. After one measurement is completed, it is necessary to re-zero and install and replace the gear on the rotating shaft, which takes time and manpower, and multiple measurements are even more difficult. and its inconvenience.

The existing motor shaft tooth runout inspection tool needs to install and replace the detection parts many times, and it takes a lot of time in the process of installing and replacing the inspection parts.

Preferably, the ratio of the main body of the lever is 1:1, and the lever seat is arranged in the middle of the fixed seat. Only a lever with a lever ratio of 1:1 can ensure that the left and right swing amplitudes are the same, and the left and right swing times are the same.

Preferably, the bottom of the fixed seat is connected with a sliding bottom plate, and the sliding bottom plate is slidably connected with the linear guide rail. Under the action of the sliding bottom plate, the entire detection can be successfully completed, and the linear guide rail can be smoothly slid within a linear range.

In the above-mentioned technical scheme, the technical effects and advantages provided by the present invention:

1. By placing the contact of the dial indicator on the surface of the lever, the rotation and swing of the lever can detect the beating amplitude of the internal gear. Compared with the traditional rotation of the internal gear and the cam to measure the beating amplitude, the swing of the lever Amplitude can be more accurate and fast measurement reading, and installation and replacement of inspection tools can be more convenient;

2. Through the relative movement of the linear guide rail and the sliding bottom plate, the main body of the lever can be easily moved to the detection range, and it can be easily pulled out when not in use, saving the time of installing and replacing the inspection parts, as well as the installation and replacement of the inspection parts. , there is no need to re-zero the dial indicator, which greatly shortens the detection time and labor consumption;

3. The ratio of the lever is 1:1 to improve the accuracy of the detection of the runout of the shaft teeth, and the swing amplitude of the lever is most easily controlled, and the resulting reading is also more accurate.
