1) Descriptions of Internal Spur Gear From the perspective of heavy-duty stable meshing, internal gears are high-strength components specifically engineered for demanding load conditions. They transmit substantial torque through the meshing of their internal tooth surfaces with external gears, maintaining stable transmission performance under high-load environments. 2) Features of Internal Spur Gear Characterised by high root strength (the root thickness of internal gears is

1) Descriptions of Internal Spur Gear From the perspective of compact space transmission, an internal gear is a type of gear whose teeth are distributed along the inner surface of a ring-shaped component. Typically used in conjunction with external gears (such as pinions or planetary gears), it enables power transmission and speed conversion within limited spatial constraints. 2) Features of Internal Spur Gear Characterised by an ‘internal meshing’ transmission structure,

1) Description of Internal Spur Gear Internal spur gears are specialised gearing designed to achieve specific motion conversion and functional integration. They serve not only as transmission components but also, in certain applications, as structural supports or motion trajectory controllers. 2) Working Principle Beyond conventional rotational motion transmission, internal spur gears can achieve substantial speed reduction ratios within specific mechanisms, such as planetary

1) Description of Internal Spur Gear From a transmission perspective, internal spur gears constitute highly efficient transmission components capable of achieving simultaneous engagement of multiple teeth and possessing robust load-bearing capacity. By enclosing the meshing region within the gear's interior, they optimise the force transmission pathway. 2) Working Principle During meshing, the contact line of internal gear pairs is longer, whilst the number of tooth pairs

1) Description of Internal Spur Gear Internal spur gears, commonly referred to as internal gears, are a type of gear whose tooth profile is distributed along the outer surface of a cylindrical body. Their tooth form is straight and parallel to the axis. They mesh with an external spur pinion to form an internal gearing pair, enabling compact coaxial transmission. 2) Working Principle Its operating principle is analogous to that of externally meshed gears, relying on

1) Features of Internal Spur Gear When an internal gear meshes with an external gear, the contact occurs between convex surfaces. Compared to the contact between two convex surfaces in external meshing, this arrangement offers a larger contact area, significantly reduced contact stress, and theoretically higher contact strength. Owing to its annular structure, the gear body exhibits minimal deformation under radial forces, possessing high radial stiffness and stability. This

1) Features of Internal Spur Gear Unlike external gears requiring external space, internal gears feature teeth distributed along the inner wall of a bore, enabling a coaxial layout for input and output shafts. This structure allows it to inherently “enclose” other components. It offers exceptionally high structural integration, incorporating functions such as bearings and housing walls into the gear itself, significantly reducing component count and system axial length. 2)

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

1)Descriptions of Internal Gear The inner ring gear is a ring-shaped gear with teeth on the inner side. When meshing with the outer gear, the two rotate in the same direction (unlike the opposite rotation between the outer gears). This design gives it unique advantages in closed transmission systems. 2)Advantages of Internal Gear a)Compact structure: The internal gear can be nestedly installed, optimizing the space utilization rate. b)High transmission efficiency: The
