Differences compared to external gear slewing bearings:
Internal gear type: Gear teeth are machined on the inner wall of the inner ring's bore. The drive pinion is located inside the bearing and meshes with the internal gears.
Comparisons:
Maintenance: External gear pinions offer more convenient maintenance; internal gear pinion replacement may require disassembling more components or accessing the bearing's internal space.
Space: External gear types require external space for pinion accommodation; internal gear types can encapsulate the drive system within the bearing, potentially achieving a more compact overall structure (though internal space is constrained).
Gear machining: External gear machining generally allows easier precision control and better guarantees of tooth surface hardness compared to internal gear machining.
