Design challenges arise in applications like humanoids where high torque is required to move and self-balance the bot. Present research focuses on development of a cycloidal gearbox for humanoid shoulder joints. Light weight gear box assembly was designed with mass 360g. Structural design analysis carried out. A 3D printed prototype developed validate motion analysis. It actuated by NEMA 17 ste...

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...

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 ...

The influence of the dynamic wear model considering tooth contact flash temperature on characteristics a gear-bearing system is studied. Firstly, meshing stiffness model, based theory, established. Then, changing surface and in process gear analyzed. Next, initial calculated Archard Finally, effects wear, friction factors, damping ratio response are results show that with increase fractal dimen...

Gears are an integral and necessary component in our everyday lives. Most of the work performed in plastic and metal but very few works available in combine effect of plastic and metal gears. The main problem while referring plastic gear is the bending strength and in case of metal gear is cost. Hence, the work is performed on metal plastic composite gear to get benefit of both. Here use the co...

To date, elliptical gear has been commonly used in automobile, automatic machinery, pumps, flow meters and printing presses for its particular non-uniform rotation. However, the dynamic characteristics of elliptical gears have not been clarified yet. In this study, The calculation as well as the experiment of two elliptical gears, which are a single elliptical gear and a double elliptical gear,...

Spur gear wears either due to rubbing action between the meshed gears or by the occurrence of unwanted elements like dust particles, metal fragments, etc. which reduces its efficiency and service life. It is always a challenging task to determine the remaining life of a component or the strength of a component once wear has occurred on teeth surface. This paper presents an application of revers...

Simulation and the resulting prediction of the dynamic behavior of an aircraft and its landing gear system during ground maneuvers is an essential part in the design process. A realistic estimation of unwanted oscillations, such as gear walk and shimmy, for the landing gear and whole aircraft can be readily obtained with an MBS-model. It is then possible to adjust the model for changes in the s...
