CARDAN JOINT FOR INERTIALLY STABILIZING A PAYLOAD

摘要

A cardan joint includes a cross-elevation assembly comprising a cross-elevation housing, a roll-elevation assembly comprising a roll-elevation housing, a payload interface assembly comprising a payload interface housing, and a suspension interface yoke comprising a suspension interface that couples the suspension interface yoke to one or more suspension bars. The roll-elevation assembly is rotatably connected to the cross-elevation assembly along a first rotation axis via a radial roller bearing and a thrust roller bearing. The payload interface assembly is rotatably connected to the roll-elevation assembly along a second rotation axis via a radial roller bearing and a thrust roller bearing. The suspension interface yoke is rotatably connected to the cross-elevation assembly along a third rotation axis via one or more radial roller bearings and one or more thrust roller bearings. The payload interface housing can be coupled to an inertially stabilized payload.
