An "internal geared sleeve" in the context of a planetary gearbox typically refers to an internal gear (also known as an annulus gear) that engages with the planet gears. This sleeve is a key component of the gearbox, providing the outer ring of teeth that the planet gears rotate within.
Function:
The internal gear, along with the sun gear (the central gear) and planet gears, allows for high gear reduction in a compact package.
Material and Properties:
Internal gears can be made from various materials like stainless steel, aluminum, or brass. Alloy steels are also a common choice for planetary gears due to their strength.
