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 ...

Wear of nonstandard involute gears with two types coatings, AlCrN and CrAlSiN, was studied. The coatings were applied by cathodic arc deposition. tested using a Niemann tester at graduated load up to the 12th stage compared noncoated gears. Both Biogear S150 gear oil PP90 universal hydraulic during these tests. thickness deposited wear teeth studied SEM their chemical compositions determined ED...

Gearing is one of the most effective methods for transmitting power and rotary motion from the source to its application with or without change of speed or direction. The bending and surface strength of the gear tooth are considered to be one of the main contributors for the failure of the gear in a gear set. Thus, determination of stresses has become popular as an area of research on gears to ...

Abstract The article presents a comprehensive study on the tooth bending strength of spur gears with progressive curved path contact, or so-called S-gears. Systematic gear meshing simulations were conducted to effects S-gear geometry parameters strength. Different geometries analysed in systematically organized manner, and comparison was made against standard 20° pressure angle involute shape. ...
