Ensuring regular movement and power transmission in gear wheels is possible with a suitable tooth profile. Although involute profiles have structure that can provide conjugate accordance the law of gearing, errors cause vibration noise occur due to flexibility elements system under dynamic conditions. Transmission depend-ing on many parameters from production oil lubrication system. In this stu...

A dynamic analysis method is firstly presented to make up the present methods for calculating the strength of the cylindrical gear pair. The transient stress distribution and variation in the process of gear meshing can be obtained by dynamic simulation, the maximum bending stress, the maximum tooth contact stress and the corresponding worst meshing locations of the gear pair can be also accura...

Gear assembly errors are an important contributor to a premature gearbox failure. This study investigates the effects of center distance deviation on polymer life. The main focus was influence stress state gear. Reference spur gears (m = 1 mm, z 20, b 6 mm) with standard involute gear profile and ratio (same pinion gear) were studied. A combination numerical experimental methods used obtain bes...

The variable hyperbolic circular arc tooth trace (VH-CATT) cylindrical gear is a new suitable for heavy loads and high speed. special structure of the provides excellent mechanical properties but also increases processing difficulty. machine tool VH-CATT prerequisite mass production, machining accuracy remains to be improved. Therefore, this paper proposes Kriging model based on glowworm swarm ...

Somer M. Nacy, Member, IAENG, Mohammad Q. Abdullah, and Mohammed N.Mohammed Abstract The Wildhaber-Novikov gear is one of the circular arc gears, which has the large contact area between the convex and concave profiled mating teeth. In (June 28, 1999), a new geometry of W-N gear with parabolic profile in normal section has been developed. This paper studies the generation of rack-cutters for p...

The paper proposes a method of cutting by generating spur gears using rack cutter with modified geometry. analytical equations the tooth profile rack-gear are deduced, both for involute zone and filleting region, based on remark that is envelope successive positions tool. undercutting radius obtained from system transcendental which requires numerical solving it. Compared to standard profile, d...
