TRANSMISSION PROFILE OF ENGAGEMENT Russian patent published in 2019 - IPC F16H1/08 

FIELD: machine building.

SUBSTANCE: gear transmission includes a pair of gear wheels, the contact line of engagement profile of which provides a convex-concave contact of conjugated gear wheels with pitch circles R1, R2, a line of centers of conjugated wheels O1–O2 and an engagement pole P on parallel shafts, engagement angle of which ranges from 0 to 70°, interface of tooth (D) and base (H) tooth profiles is made with straight line section, conjugation of gear wheel contact profile is made with specified gap size δ. Line of contact of gearing profile is arranged in the form of sections in series conjugated sections of straight line with subsequent smoothing. Smoothing of tooth profile of tooth of engagement is made so that smoothing curve has minimum variation of curvature along profile and is located on one side in relation to straight line of direction of section 1 of tooth root. Smoothing of tooth engagement tooth profile is made so that smoothing curve has minimum variation of curvature along profile and is located on one side in relation to straight line of direction of section 1 of tooth profile. Smoothing of the profiles of the stem and the tooth of the engagement tooth is made so that variation of the gap between the profile of the root and tooth of engagement is minimal.

EFFECT: enabling increase in the engagement reliability.
