KSI2.5-80 is a steel internal gear with a module of 2.5, 80 teeth, and a pitch diameter of 200 mm. It has a face width of 25 mm, an outside diameter of 260 mm, and a bore diameter of 195 mm. The gear is rated for a bending strength allowable torque of 607 N·m (114 kgf·m) and a surface durability allowable torque of 61.9 N·m (11.6 kgf·m). Backlash ranges from 0.17 to 0.37 mm, and the part weighs 4.25 kg. It is designed for use in planetary gear systems with precision grade equivalent to JIS B1702-1:1998 N8. The material is S45C with a tooth hardness below 194 HB and a 20° pressure angle.
Module 2, 5-8 Tooth Mild Steel Internal Gear
Internal gears are spur gears with teeth on the inside of the gear as opposed to on the outside. They rotate in the same direction as the driving gear (a spur gear of the same module), turning it. They frequently serve as a component of a planetary gear configuration, in which a driving gear (typically, the sun gear) rotates planet gears inside of an internal gear (also known here as an annular gear).
Types Of Planetary Gear Systems
The diagram above illustrates the three types of planetary gear systems. There can be numerous variations in speed ratios and rotational directions created depending on the configurations of which shafts are used as input and output.
Our inch and metric internal gears are available in stainless steel, aluminum, and brass. They are offered in pitches ranging from 96 to 24 and modules 0.5 to 3.
