GEAR TRAIN Russian patent published in 2002 - IPC

FIELD: mechanical engineering; spatial gear trains between orthogonal intersection axes for transmission of torque. SUBSTANCE: drive wheel tooth is engageable with driven wheel tooth and conjugation angle of drive wheel tooth with driven wheel tooth is determined by the following dependence: , where , are coefficients defining position of flanks of drive wheel teeth; α - is pressure angle; ϕ₁, ϕ₂ are angles of turn of drive and driven wheels; i = ϕ₂/ϕ₁ - is gear ratio (upper signs refer to right-hand rotation and lower signs refer to left-hand rotation of driven wheel). EFFECT: improved service characteristics of gear train. 2 dwg
