Why can't the tooth width of straight bevel gear be too big?
In addition, because the tooth of the straight bevel gear is gradually tapered from the outside to the top of the cone, the tooth width is too large, which is harmful to the processing.
Then the tooth which is equivalent to 2 modules, so the gear width on stress improvement is not big. So, generally choose teeth width is not greater than the cone bus 1/3.
The tooth of a straight bevel gear is progressively tapered from the outside to the cone, for example, a 3 modulus bevel gear, if the width of the tooth reaches 1/3 of the cone generatrix,
