Скачать или смотреть The inspection of gear rack

The inspection of gear rack mainly depends on the tooth profile, tooth pitch and flatness. The best inspection method is to use the CMM, so that all the data can be obtained intuitively. However, subject to the time and place, it can also be tested with an outer micrometer and feeler gauge.
The specific test method is to put the rack on a smooth table (marble platform is the best) and measure its plane with a feeler gauge. The outside micrometer is matched with the inspection rod to measure the tooth pitch.
