Contact сharacter of work surface of cylindrical gears tooth with conchoidal engagement line depending

Abstract

Load capacity of gears depends on the character of work surfaces contact: two convex contact or contact the convex and concave surfaces. Therefore, the actual solution to the problem is to determine the geometrical parameters of the tooth, providing the most rational given character of their work surfaces contact. This fully applies to the gears with conchoidal engagement line for which this problem has not been studied yet.Тhere have been gotten the conditions defining the character of tooth work surface contact with conchoidal engagement line depending on the geometrical parameters of the original contour. There have been defined the original contours parameters providing convex-concave tooth contact and the contact of two convex teeth in the engaging meshing pairs. There have been given recommendations as for defining the parameters of the original contour depending on the character of contact in cylindrical spur gear work surfaces.
