Comparison ofand in gear reducer
1.It is difficult and uneconomical to make and assemble a large number of thin-walled spur gears, so they are made into a gear which is connected and whose teeth are in the direction of helix;
2.Helical gears are not like spur gears, they can cause poor axial forces. However, the advantages in vibration and strength are far better than the disadvantages caused by axial thrust and slightly increased manufacturing cost. Therefore, the helical gear rather than the spur gear is used in the reducer manufacturing.
