Abstract
According to various embodiments, a space suit joint is disclosed. The space suit joint includes a contact bearing having a plurality of contact points with an angular offset of a centerline in a radial direction and an angular offset from the centerline in an axial direction. The space suit joint further includes a ferrofluid pressure seal comprising an inner and outer race with a magnetic circuit embedded therein.
Claims16
A space suit joint comprising:
- a ferrofluid pressure seal comprising an inner and outer race with a magnetic circuit embedded therein, the outer race having an axial centerline;
- and
- a contact bearing having a plurality of balls between the inner race and outer race, each ball of the plurality of balls separated from another ball by a spacer ball, the contact bearing having a radial centerline extending perpendicular from the axial centerline through a center point of a ball of the plurality of balls positioned between the inner and outer race, the contact bearing having:
- a plurality of contact points, including at least a first contact point and a second contact point on each of the inner race and outer race;
- for each of the inner race and outer race, a first angle formed between a first line extending from the center point to the first contact point and a second line extending from the center point to the second contact point;
- a first offset angle formed between a radial centerline and a line bisecting the first angle;
- and
- a second offset angle formed between the line bisecting the first angle and the first line or the second line.
