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...

Tooth flank twist is a common phenomenon in the helical crowning modification of cylindrical gear, which reduces performance gear. At present, measurement tooth still stage replacing surface with line. The development 3-D technology makes acquisition gear information more comprehensive and complete. By processing point cloud data, deviation on can be found, particularly important for improving ...

New commercial Point Laser Triangulation (PLT) probes enable Coordinate Measuring Machines (CMMs) to take faster, noncontact, accurate measurements. In this paper, we address how to apply this technology to inspect helical gears. Traditionally, gears are inspected with slow, costly, and dedicated machines. The proposed flexible inspection system with a fast measuring probe can significantly red...
