[Chemical Knowledge]：How to measure gears correctly? Matters needing attention in measuring gears

Read： 466 Time：9months ago Source：Transform the World with Simplicity

Gears are commonly used parts in mechanical transmission, and their transmission accuracy is directly related to the performance of the entire mechanical equipment. Measuring the size and shape error of the gear is an important part to ensure the quality of the gear. When measuring gears, you need to pay attention to the following points:

1. Select the appropriate measuring tool
gear measurement requires the use of precision measuring tools, such as micrometer, height gauge, outside micrometer, etc. Choosing the right measurement tool can ensure the accuracy of the measurement results.

2. Cleaning the workpiece and measuring instrument
Before performing gear measurement, it is necessary to ensure that the surface of the workpiece and the measuring instrument are clean to prevent impurities from affecting the measurement results.

3. Pay attention to the measurement environment and temperature
. The measuring gear needs to be carried out in a stable environment to avoid interference from external factors. At the same time, the change of temperature will also affect the measurement results of the gear, so it is necessary to pay attention to the control of the measured ambient temperature.

4. Measurement
in combination with drawing requirements When measuring gear size and shape and position error, it is necessary to measure in combination with relevant drawing requirements to ensure the accuracy and compliance of the measurement.

5. Repeated measurement and comparison of results
In order to reduce measurement errors, it is recommended to perform multiple repeated measurements and compare the measurement results to find out possible errors and make corrections.

The above are some matters that need to be paid attention to when measuring gears. The correct measurement method can ensure the quality and accuracy of gears and improve the performance and service life of mechanical equipment.
