The B series industrial gear units feature an invertible housing and a very broad gear ratio range.
The finely stepped sizes provide additional variability during installation and use.
The B Series 90 Degree Right Angle Bevel Gear Unit from one shaft to another through the meshing of two bevel gears. Since the gear teeth are helical, the contact line changes gradually during meshing, reducing shock and vibration and making the transmission smoother. It is a mechanical transmission device used to transmit power and motion, mainly used for power transmission between intersecting shafts. It is characterized by helical gear teeth, and compared with straight bevel gears, it has higher transmission efficiency, smoother running performance and lower noise.
1.The design of helical teeth makes the meshing smoother, reduces the energy loss, and the transmission efficiency is higher than that of straight bevel gears.
2.Helical gear meshing process contact line gradually change, reduce the impact and vibration, running more smoothly.
3.The design of helical teeth reduces the shock and vibration during meshing, and the operation noise is lower than that of straight bevel gears.
4.Helical gear design increases the contact area of gears, improves the load carrying capacity, suitable for heavy-duty working conditions.
5.Adopting high-strength materials and precision machining, the gears have excellent anti-wear and anti-fatigue performance and long service life.
