The measurement of the gear is a prerequisite for use. Only after the measurement, we have a familiar understanding of the gear parameters, and then we know the suitable application space of the gear, so that it can be used in a suitable place, not only can meet the needs of use, but also It will not cause gear wear due to improper environment.There are three measurement methods for gear measurement. I can share them with you. If readers are interested, I will introduce them to you.

　　(1) Measure the tooth thickness and tooth height of the indexing circle chord.Its characteristic is that when measuring the tooth thickness of the indexing circle chord, the addendum circle should be used as the measurement reference, but the accuracy of the addendum circle is not high when the gear is actually working, so the design and processing accuracy of the addendum circle is generally low, which affects the chord Thick measurement accuracy.

　　(2) Measure the thickness of the fixed chord teeth and the height of the fixed chord teeth.Its characteristic is that when calculating the measured value, it is only related to the modulus and tooth profile angle of the measured gear, and has nothing to do with the number of teeth. In addition, the modulus and tooth profile angle of the standard gear have been standardized, so the calculation is very convenient.However, when measuring the tooth thickness of a fixed chord, the addendum circle should be used as the measurement reference, which affects its measurement accuracy.

　　(3) Measure the length of the common normal.Its characteristic is that the measuring tool is simple, the measurement is convenient and accurate, and the manufacturing error of the addendum circle has no influence on the measured value of the common normal length.

　　This article introduces this knowledge to everyone. If readers have any doubts, please contact customer service.Gears are important parts of many equipment. Choosing suitable gears is conducive to the operation of the machine. Before buying gears, we can understand the parameters to see if it is suitable for our own use.There are many types of gears, including precision gears, copper gears for instruments, small modulus gears, tin bronze gears, etc., for your choice.
