Effective repair of worn big gear has large influence on ensuring safety production and enhancing economic benefits. A kind of intelligent repair welding method was put forward mainly aimed at the big gear restriction conditions of high production cost, long production cycle and high-intensity artificial repair welding work. Big gear repair welding mechanism was designed in this paper. The work...

Abstract The load spectrum is a crucial factor for assessing the fatigue reliability of in-service rolling element bearings in transmission systems. For bearing high-speed train gearbox, measurement technique based on strain detection outer ring was used to instrument and determine time histories distributed under different gear meshing conditions. Accordingly, total radial carried by compiled....

The gearbox is a complex system component and its core is the gear shafting. The gear system output the power to the drive shaft with speed changing through the engine. In the actual work, because of the installing error, load distortion and shock load situation, the correct meshing condition of gears was destroyed. 3D model of transmission gear was firstly built up by using SolidWorks software...

This paper presents design and analysis of torque and flux density in perpendicular magnetic gear with different magnetic materials, dimensions and air gap. The results were compared to each other. This type of gear offers both high gear ratio and high torque. Moreover the low speed side is connected to prime mover and high speed side is connected to load after analysis, which is sui table for ...

The paper aims at the complex situation of the tractor field operation and adopts the gear shift rule of two parameters to control the six gear shift of the tractor. Using the artificial neural network chip the model number of which is ZISC036 and the computer on slice the model number of which is PIC17C42 establishes the controller of the radial basis function artificial neural network-RBFANN....

In order to solve the limitation of cylindrical geared linkage in trajectory realization, this paper make the non-circular gear pair and double crank hinge five-bar as closed combination, and to probe the feasibility and method of designing non-circular gear based on the given position points in five-bar linkage trajectory region. The discrete rotation angle sequences of non-circular gear pair ...
