Laser cutting machine adopts main advantages compared to straight tooth bevel

Laser cutting machine adopts comparative straight tooth bevel the main advantage of spur gears meshing, the contact line is parallel to the axis of the straight line, and a pair of tooth profile along the tooth width into mesh mesh or exit at the same time, easy to cause shock and noise, the driving stability is poor, is not suitable for high speed gear transmission. Helical cylindrical gear meshing, because of a certain limit depth, therefore in the process of two tooth profile meshing, the contact line length of zero growth gradually, from one location and then gradually shortened, until out of meshing, namely the helical gear into and out of contact are to be carried out gradually, so the smooth transmission, low noise. In addition, as a result of the helical gear tooth is tilted, the meshing teeth in logarithmic than straight gear at the same time, so the contact ratio is bigger than straight gear. As a result of the helical gear tooth is spiral, so in the meshing zone, line the total length of the tooth surface contact than the same parameters of spur gear tooth contact line length, so the bearing capacity of the helical gear is bigger also
