When selecting the tooth width, att

When selecting the tooth width, attention should be paid to the effect of the tooth width on the axial dimension, quality, working stability, strength and even force of the transmission.To minimize the axial size and mass of the drive, a smaller tooth width should be selected. On the other hand, the reduction of tooth width weakens the advantages of helical gear stable transmission. At this point, although the method of increasing the spiral Angle of the gear can be used to compensate, but at this point the bearing bearing axial force increases, reducing its service life. Narrow tooth width will increase the working stress of gear.. If a wider tooth width is chosen, the gear will tilt due to the deformation of the shaft, which will lead to uneven stress along the tooth width direction, resulting in unbalanced load, reduced bearing capacity, and uneven wear in the tooth width direction.Generally, the tooth width is selected according to the module m(MN) of the gear.Straight teeth, is the tooth width coefficient, 4.5-8.0;Helical teeth, 6.0-8.5.When using a meshing sleeve or synchronizer to shift gears, the working width of the meshing teeth can be 2-4mm in a single selection.The tooth width coefficient of the first shaft constant net gear pair can be larger, which can increase the length of the contact line and reduce the contact stress, so as to improve the transmission stability and gear life. For each gear with the same module, the lower gear has a slightly larger tooth width coefficient.
