This publication provides the result of trying out and operation event of Novikov gearing. It supplies the grounding, engineering thoughts of geometry and power research, definition of the gearing caliber and suppleness with account of its manufacture and meeting error. It outlines the tips on the average task of easy rack profile parameters, accuracy scores and layout energy protection elements. additionally, methods of load-bearing potential crucial raise are defined and a number of other unique types of Novikov gearing are proven. The examples of engineering and computer-aided calculations of Novikov gearing in response to the defined ideas are given.

Tooth profile of hobs, intended for manufacture of Novikov gears, is usually measured at the projection apparatus according to precisely produced Plexiglas samples, the profile deviation is regulated by the standard , depending on the hob accuracy rating. However, experience showed that, besides the general control of the hob tooth profile, it is necessary to control the profile deviation at points of convex and concave active areas, corresponding to theoretical points of contact on the tooth of the basic rack profile (Fig.
9) The question of reasonable distribution of x* between the pinion ( x*1 ) and gear ( x*2 ) in order to increase the contact strength of a gearing is described in . 2. 11) where u z2 / z1 is the gear ratio of the pair. 12) d f 1,2 d1,2 2m( x*1,2 h*f ). 14) And the nominal radial backlash in the pair is c m( h*f h*a ). 3. MULTIPLE-POINT CONTACT, TOTAL AND PHASE FACTORS OF TOOTH AXIAL OVERLAP According to many references (for instance, ), it is known that the contacting of teeth of NG TLA takes place in several points, and when the engagement phase (angle of the pair rotation) is changed, the number of contact points also varies from a certain minimum to maximum.
