The purpose of the research is to improve method for calculating lifetime bevel gears with a circular tooth driving axle BELAZ dump truck hydromechanical transmission. An analysis domestic and foreign calculation methods showed that when determining contact stresses in gearing, influence modification side surfaces teeth on magnitude internal dynamic loads not taken into account, which leads sig...

The precision forging process of straight bevel gear are simulated by using finite element software DEFORM-3D. key parameters (heating temperature, upper die movement velocity, friction factor, web thickness and the height) forming optimized orthogonal test. Taking minimum load good corner filling as goals, technological for obtained, that is, heating temperature is 1200 degrees Celsius, veloci...

In the machining of split straight bevel gears, stiffness changes and internal stress are redistributed, which leads to serious deformation gear blank after machining. To rectify this problem, q finite element model is established by transforming processing information into simulation calculation information, carried out. Considering material, design, process blank, characteristics laws variati...

Abstract Contour bevel gears have the advantages of high coincidence, low noise and large bearing capacity, which are widely used in automobile manufacturing, shipbuilding construction machinery. However, when surface quality is poor, effective contact area between gear mating surfaces decreases, affecting stability fit thus transmission accuracy, so it great significance to optimize contour ge...

For enterprises of the metallurgical industry, task increasing operational life drawing mills is urgent. The reasons for a significant decrease in resource and an increase number equipment downtime are related to problems. Downtime due emergency failures account up 45 % mill’s operating time per month. paper considers drive scheme mill analyzes loss restore its working condition. It shown that ...
