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

1)Descriptions of Internal Gear Internal spur gears are widely used as transmission components in devices such as reducers, planetary gearboxes, and slewing bearings. 2)Features of Internal Gear a) The processing of internal gears is more difficult than that of external gears. Special tools are required to avoid interference. b) Hardness and precision are usually enhanced through processes such as quenching and gear grinding. 3)Advantages of Internal Gear a) Multifunctional

1)Descriptions of Internal Gear The internal spur gear is a kind of internal meshing gear that transmits power and motion by meshing with the external gear through its straight teeth. 2)Features of Internal Gear a) During the meshing process, the contact line of the tooth surfaces is parallel to the axis, resulting in good transmission stability. b) Due to its internal meshing characteristic, it has a stronger load-bearing capacity than external gears of the same size. 3
