What are the principles and advantages of square rail helical gear drive for woodworking engraving machines?
According to the gear profile, the gear can be divided into involute gear, circular arc gear and cycloid gear. It can be divided into cylindrical gear, bevel gear, non-circular gear, rack and worm gear according to its shape.According to the shape of its teeth line can be divided into straight gear, helical gear, double helical gear curve (such as hypoid) gear. According to the working conditions of gears, they can be divided into three categories: closed type, open type and semi open type. In addition, the gears can be further classified according to the relative positions of the two gear axes.
The transmission side rail rack is to rely on the combination of continuous meshing tooth movement transmission, gear transmission is respectively arranged on the driving shaft and driven shaft through a gear, using two meshed gears, the transmission mode of motion and power transmission. Many classification methods of gear and gear transmission, with different classification standards, in accordance with the relative position of the gear tooth profile, gear shape, two axis gear and transmission gear between the external structure classification.
Woodworking engraving machine now mostly adopts the transmission side rail rack for processing, compared with the screw drive side rail rack combination original faster, more in line with the characteristics of small machine tools woodworking engraving rapid engraving and milling, and woodworking engraving machine is the standard Taiwan square straight line guide rail and high precision milling helical rack. Both processing speed and accuracy are much higher than other brands.
