Preparatory work before cylindrical gear surveying and mapping

　　Nowadays, the types of the same product on the market are relatively diverse, and many people seem to be blinded because they don’t understand it when they buy it.For example, there are many varieties of noodles, but if you like thin noodles, you can buy thin noodles, and if you like thick noodles, you can buy thick noodles. Just eliminate the unnecessary ones according to your needs.The utilization rate of gears is also relatively large. Although its value is not obvious from a standalone perspective, many machines cannot leave it.Cylindrical gear is a type of gear. It needs preparation work before surveying and mapping. Let's take a look.

　　1. Although there are many parameters and dimensions of cylindrical gears, the standard system of various cylindrical gears stipulates that the modulus or the diameter pitch is used as the calculation basis for other parameters and dimensions.Therefore, the surveying and mapping work must make every effort to accurately determine the size of the modulus or the diameter of the pitch. At the same time, the pressure angle is the basic parameter to determine the tooth profile, and accurate determination is equally important.

　　2. It is necessary to understand the usage and production country of the cylindrical gear, so that we can estimate the standard system adopted by the cylindrical gear.You can also observe the tooth profile of a cylindrical gear. If the tooth profile is curved and the bottom of the tooth groove is narrow and arc-shaped, it can be preliminarily judged as a modular system, and the standard pressure angle is mostly 20 degrees.Observing that the tooth profile is relatively straight and the bottom of the tooth groove is wider and the arc is small, it can be preliminarily judged as the diameter control, and the pressure angle is 14.5 degrees. The gear hob or standard rack samples can also be used for comparison to determine which pressure angle.

　　After understanding the above situation, the cylindrical gear can be surveyed and mapped. You can learn about the above preparations.There are many types of cylindrical gears, and there are more manufacturers of cylindrical gears on the market. There may be differences in quality. In order to increase the service life of cylindrical gears, everyone should try to choose good quality cylindrical gears and avoid buying some cylindrical gears. A product whose gear price is too low.There are not only various types of gears, but also gear couplings, flanges and other products on our website. You can come in and take a look.
