Surface defect detection and dimension measurement of automotive bevel gears by manual inspection are costly, inefficient, low speed and low accuracy. In order to solve these problems, a synthetic bevel gear quality inspection system based on multi-camera vision technology is developed. The system can detect surface defects and measure gear dimensions simultaneously. Three efficient algorithms ...

This perspective discusses the important aspects of the design of molecular gear systems based on triptycene. Molecular systems are categorized into three classes according to the orientation of the gear axes: i) bent (bevel gears), ii) linear, and ii) parallel (spur gears). To date, no examples of molecular gears in which the axes of rotation lie in parallel have been reported; correspondingly...

Helical bevel gears have inclined or twisted teeth on a conical surface and the common types are skew, spiral, zerol, hypoid gears. However, this study does not include Due to geometric complexities of gears, commonly used methods in their design based concept equivalent virtual spur gear. The approach paper is following assumptions, a) helix angle helical equal mean spiral angle, b) pitch diam...
