Customized non-standard gear and impact angle error coincidence degree
Non-standard gear custom angle error: ① hob teeth have tooth angle error; ② edge sharpening the teeth of the rake face of the non-radial error. Because after the knife has a lateral flank angle, the current angle is positive, the addendum become fat, a negative rake angle, addendum thinner. ③ edge sharpening the teeth of the rake face of the non-axial error. It refers to a straight groove hob rake face bore axis and axially parallel error. Make teeth tooth deviation from the correct position, the left and right edges to form a toothed deviation ranging skew.
Non-standard gear custom coincidence of important parameters affecting the gear can continuous transmission. Coincide gear is primary or secondary, is called the driven wheel and drive wheel drive wheel drive wheel push, push push wheel driving wheel, and that it is important to contact ratio gears, a pair can even correct meshing of gears more than a few the condition is two must modulus equal, pressure angle equal.
