1)Descriptions of Internal Gear
Internal spur gears refer to gears whose teeth are distributed on the inner surface of a cylinder or cone (i.e., internal gears),

with a straight tooth profile (parallel to the axis), and they are usually engaged in transmission with external gears.
2)Features of Internal Gear

a) The tooth groove is on the inner side, and the tooth tip points towards the center. The meshing mode with the outer gear is opposite.

b) The straight tooth design makes the processing relatively simple and is suitable for standardized production.

3)Advantages of Internal Gear

a) Compact structure: Internal meshing saves space and is suitable for applications requiring small-sized transmissio.

b) High transmission efficiency: The friction loss in straight gear meshing is small, and the efficiency can reach over 95%.
