For a long time, the products of many manufacturing enterprises in China are at the middle and low end of the global value chain, and product design, key components and process equipment mainly rely on imports. At present, the overall localization level of the main equipment for mining operations,...
According to the actual load condition of the system, define the input and output of the involute spur bevel gear model. After the system load spectrum is formed, run romax for static analysis, and the system static analysis results can be obtained, including shafting deformation and stress diagram, strength...
At present, there are many software for gear transmission dynamics analysis, such as ANSYS, romax, Masta, kisssoft and so on. ANSYS completes the transient dynamic analysis. Kissoft is good at the automatic generation of optimization parameters, but the results are not intuitive and detailed in further microscopic analysis. Masta...
According to the performance requirements of the reducer, the technical parameters are determined on the basis of the above structural scheme, and eight links are discussed, including transmission ratio distribution, motion and motion parameter design, mechanical model establishment, strength design of involute gear pair, shafting structure and strength check,...
This paper discusses the research status of tooth modification technology, gear transmission dynamics theory and gear transmission dynamics simulation analysis at home and abroad. Through the establishment of accurate three-dimensional solid model and mathematical analysis model of spur bevel gear, the dynamic analysis of spur bevel gear transmission before...
Mechanical equipment has higher and higher requirements for the stability, vibration performance and accuracy of gear transmission, but various errors and elastic deformation of gear transmission system will lead to abnormal meshing of gear teeth, dynamic problems of gear transmission and vibration and noise. The methods to improve the...
In the primary stage of gear transmission dynamics research, based on the lack of effective numerical methods to solve the gear transmission analysis model, some scholars always linearize the nonlinear factors in the gear transmission system with the help of various mathematical means to solve the practical problems in...
1) Analytical theory The theoretical basis of gear transmission dynamics research is mechanical linear dynamics theory and nonlinear dynamics theory, but the two theories develop with the development of gear transmission dynamics research. Before the 1950s, gear transmission was usually studied as a single degree of freedom system, and...
When the central bevel gear transmission system works, the fatigue fracture fault of the central bevel gear often occurs due to the vibration of the central bevel gear within the working speed range. This kind of fault seriously endangers the flight safety of the aircraft and may cause significant...
There are two kinds of torsional vibration of bevel gear transmission system: low-frequency torsional vibration and high-frequency torsional vibration. Low frequency torsional vibration is determined by the vibration of the system. For the central bevel gear of aeroengine, because the natural frequency of low-frequency torsional vibration is usually outside...
