According to different working conditions, gear transmission can be divided into closed type and open type; According to different use conditions, gear transmission can be divided into high-speed, low-speed, light load and heavy load; According to the material properties of gear teeth, gear teeth can be divided into soft...
Industrial gear precision measuring instrument is mainly used to detect whether the precision of industrial gear after machining meets the factory requirements. The main shape parameters of industrial gears (such as tooth profile error, tooth direction error, cumulative pitch error, tooth thickness error, etc.) must meet a certain machining...
Zhou jian magnitude to a gear mesh type bending – twist mechanical model considering the meshing stiffness and error of numerical analysis, and output bearing dynamic load response to the reducer vibration noise radiation of FEM/BEM model input bearing dynamic load excitation, node location analysis get housing distribution process...
Material selection The most commonly used material of gear is steel, followed by cast iron, nonferrous metals, nonmetal, etc., but for some gears under harsh working conditions, medium carbon steel or medium carbon low alloy steel can not guarantee the service performance. At this time, alloy carbon steel (20CrMnTi,...
Frequency modulation (also known as phase modulation) is the frequency conversion signal formed when the carrier signal is modulated by the modulation signal. Some factors, such as gear speed fluctuation, pitch error caused by indexing error in machining and so on, will cause the change of meshing speed and...
When the gear has a large period fault, such as motion eccentricity and geometric eccentricity, the frequency spectrum of the simulated gear meshing vibration signal is as shown in the figure. It can be seen from the figure that the amplitude of harmonic component will increase linearly with the...
