The advantages of laser cutting machine helical gear transmission way

by：Transon 2020-10-28

Linear transmission mode of laser cutting machine machine tool equipment, gear and rack transmission applied to a wide range. Commonly used gear rack and into two kinds of straight teeth and helical teeth. The helical gear transmission way obvious advantages: 1, meshing performance is good, little noise. When the straight tooth gear meshing, a pair of tooth profile along the tooth width into mesh mesh or exit at the same time, not only easy to cause shock and large noise, also influence transmission smoothness, therefore is not suitable for high speed gear transmission. In helical gear tooth contact line is sloping straight line to the gear axis, helical cylindrical gear meshing with the depth of tooth has certain limitations, so in the process of two tooth profile meshing, the contact line length by 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, thus smooth transmission, low noise, at the same time, this style of mesh and reduce the influence of manufacturing error on the transmission. 2, contact ratio. Can reduce the load of each pair of gear teeth and the increase of relative carrying capacity of the gear, prolong the service life of the gear, and smooth transmission. 3, standard bevel gear does not produce few teeth relatively less straight gear root cutting, therefore, adopt bevel gear transmission can be more compact
