1)Descriptions of Internal Gear
The internal straight tooth is a basic form of an internal gear, and it has unique characteristics compared to types
such as internal bevel teeth and internal herringbone teeth.
2)Features of Internal Gear
a) The straight teeth have no axial force, making the bearing design simpler, while the inward beveled teeth will generate axial thrust.
b) The processing cost is lower than that of the internal bevel gear, but its load-bearing capacity and noise reduction performance are slightly inferior.
3)Advantages of Internal Gear
a) Economical: Low processing cost, suitable for medium and low-load scenarios with budget constraints.
b) Maintenance is simple: there is no axial displacement problem, and assembly and debugging are easier.
