Gear pitch line velocity equation

WebVelocity factor for generated teeth of Bevel Gear is defined as the ratio of the static load at the failure on the gear teeth to the dynamic load onto it at failure and is represented as C v = (5.6/(5.6+ sqrt (v))) or Velocity Factor = (5.6/(5.6+ sqrt (Pitch Line Velocity of Bevel Gear))). Pitch Line Velocity of Bevel Gear is defined as the ... WebThe spur gear hasa larger pitch radius than standard, by the amount xm. Also, the pitch line of the rack has shifted outward by the amount xm. Table 4.5 presents the calculation of a meshed profile shifted spur gear and rack. If the profile shift coefficient x 1 is 0, then it is the case of a standard gear meshed with the rack.
