1) Descriptions of Straight Bevel Gear
A straight bevel gear is a type of bevel gear that transmits power and motion through a straight tooth profile.
Its load-bearing capacity is significantly influenced by the tooth profile and the material.
2) Features of Straight Bevel Gear
a)During meshing, a single tooth is in contact, resulting in a relatively small bearing area.
b)There is impact during the transmission process, and the noise is relatively loud.
c)It needs to be installed precisely and symmetrically; otherwise, it is prone to uneven loading.
3) Advantages of Straight Bevel Gear
a)Axial force is small: There is no axial thrust generated by the helical angle, and the bearing load is lighter.
b)Maintenance is simple: The structure is simple, and fault diagnosis and replacement are easy.
c)Suitable for medium and low-speed transmission: Performs reliably under low-speed and medium-load conditions.
