The S1E08ZM08S108 is a metric internal gear with 108 teeth, 0.8 module, and 20° pressure angle, made from 303 stainless steel. It has a bore diameter of 108 mm, an outside diameter of 86.4 mm, an inner diameter of 84.8 mm, and a face width of 8 mm. The gear is designed for use in planetary gear systems where it engages with external spur gears of the same module. The part is mounted with a precision fit specified as H9 for bore and js10 for outside diameter, consistent with the series' tolerance standards.
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.
