GEAR WHEEL Russian patent published in 2016 - IPC F16H55/12 

FIELD: machine building.

SUBSTANCE: invention relates to gear transmissions with wheels of internal engagement. Gear wheel comprises hub (1), body (2) in form of disc, rim wheel (3) and toothed rim (4) with teeth (5). Between end of rim (4) and end of body (2) there is gap (a) throughout entire height of rim teeth. In gap (a) insert (6) is proposed, with height equal to height of technological gap (a) with external diameter equal to rim wheel (3) inner diameter D₁ and with ID equal to diameter D₂ of toothed rim (4) top circle. Circular insert (6) inner profile is identical to wheel toothed rim (4) profile. Between hub (1) and circle D₃, described in plane on wheel body (2) by points of teeth of pair gear (7) with diameter D_w, with minimum clearance Δ relative to said circle, on wheel body (2), perpendicular to it and aligned with wheel rotational axis, thin ring (8) with width (B₁) is fixed. Upper part (9) of ring (8) (with width B₂) is bent at obtuse angle towards wheel hub 1.

EFFECT: higher operating performances.
