Design and Simulation of a New Bevel Multi-Speed Gearbox for Automatic Gearboxes

چکیده
Abstract: In this paper, a new mechanism was developed as a gearbox for power transmission between concentric shafts. With this approach, reduction ratios range from 10:1 to millions to one is possible for single-stage. This mechanism is very cheaper than planetary gears. The mechanism consists of one drive shaft and one driven shaft, conical gears which one of them is fixed and the others are driven. In this mechanism, with attention to the type of design, despite very small occupied space, by combination several ratios bevel gear can use as a gearbox. We first present the kinematic diagrams and then the equations of motion. Simulation results using Visual Nastran, Autodesk Inventor Dynamic, and COSMOS Motion software with three different input rotational speeds showed that this mechanism can have high reduction ratio. Finally, tension analysis of the mechanism using ANSYS workbench software showed that the highest tension occurred in the pinion gear No. 2. [Report and Opinion. 2010;2(3):1-7]. (ISSN: 1553-9873).

Identifying fault categories, especially for compound faults, is a challenging task in mechanical fault diagnosis. For this task, this paper proposes a novel intelligent method based on wavelet packet transform (WPT) and multiple classifier fusion. An unexpected damage on the gearbox may break the whole transmission line down. It is therefore crucial for engineers and researchers to monitor the...

Studies on fault detection and diagnosis of planetary gearboxes are quite limited compared with those of fixed-axis gearboxes. Different from fixed-axis gearboxes, planetary gearboxes exhibit unique behaviors, which invalidate fault diagnosis methods that work well for fixed-axis gearboxes. It is a fact that for systems as complex as planetary gearboxes, multiple sensors mounted on different lo...

A new method based on principal component analysis (PCA) and artificial neural networks (ANN) is proposed for fault diagnosis of gearboxes. Firstly the six different base wavelets are considered, in which three are from real valued and other three from complex valued. Two wavelet selection criteria Maximum Energy to Shannon Entropy ratio and Maximum Relative Wavelet Energy are used and compared...
