The effect of initial data on the properties of a self-locking gear

Many self-locking mechanisms including cylindrical self-locking gears (CSLG) are highly efficient when performing a forward stroke. The use of such gears in machine drives makes it possible to improve their design and arrangement and reduce the size and weight by reducing or eliminating the brakes. This study evaluates the influence of the angle of the CSLG profile on the forces in gears and the reactions in the traction and brake release modes, on the change of reduced radii of curvature and the sliding velocity of profiles as well as the influence of the sliding friction coefficient range in engaged teeth on the parameters and properties of conventional and reverse CSLGs. The results of this study improve the knowledge of the CSLGs and will allow the developers of new equipment to use them in the design of new self-locking drives.
