The transmission system of the cutting section (hereinafter referred to as the rocker arm) of the imported 6C shearer of M company is shown in the figure. The transmission idlers are all spur gears, with an overall transmission ratio of 47.225, a motor power of 750 kW and a...
It is a long and tedious process to calculate the parameters of involute gear transmission system in reducer design. In order to improve efficiency, Shen Huipeng and others designed a professional app that digitizes the parameterization process of the involute gear transmission system, which is used to calculate various...
1) Inherent characteristic analysis At present, the analysis of the natural characteristics of involute straight bevel gear system generally includes the analysis of gear transmission, the natural frequency and vibration mode of involute straight bevel gear wheel body and box; Research on the relationship between system structure and inherent...
Compared with meshing stiffness and backlash, transmission error is the main internal excitation of involute spur bevel gear system. The transmission error of involute spur bevel gear is the offset distance between the actual position of the gear tooth and the theoretical position on the meshing line in the...
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...
