Industrial gearboxes for sale are available in two types of tooth that can be both used for parallel and angled drives. There are straight (spur) and helical (spiral) types of tooth. Straight gearboxes are much easier to manufacture, use and inspect than helical gearboxes, so they can be edited easier at the assembly stage. When compared to a helical gearbox, the only disadvantage of straight gear is in the tooth engagement process. The whole of the spur tooth enters engagement at the same time, causing any spacing error to make a noise or interference.
For speeds below 36 km/h in drives, spur gears are the obvious choice. Also, spur gears are used in drives that do not push the teeth to their limits and where gears are required to slide axially in and out. Helical gears, on the other hand, are used on most modern gear cutting machines. Since they have a wider face, helical gears would take longer to machine and require a more expensive investment than the spur gears. One great advantages of helical gearboxes for sale is that they are capable of carrying up to 50% more load, which can be very important for some industrial applications.
For most industrial applications, helical gearboxes are superior over straight gearboxes, especially for noise-sensitive applications or where the pitch line speed over 36 km/h. Another advantage of the innovative helical gear is that is easier to design and manufacture to fit a particular centre distance, because it features more parameters that can be re-arranged. The only big disadvantage of helical gears is the axial thrust, which is provided by the gears when they are working. Gearboxes for sale can be designed using the same type of gearing or a combination depending on the application, powers and speeds.
