Flexible fabric fits over variety of assembly shapes to contain debris produced by detonations or safety tests. Bag material is woven multifilament polyamide or aramid. Belt loops hold bag to clamp. Ring supports explosive nut structure and detonator wires, and after nut is mounted, bag and clamp are slipped over ring and fastened.
Solid lubricant applied to porous roller bearings prior to use in ultrahigh vacuum
Rolling element bearings in spacecraft mechanical systems use solid lubricant composites of polytetrafluoroethylene in the bearing cage which functions as the lubricant reservoir. The cage spaces the rolling elements equally and provides the lubricant at the bearing load-carrying surface.
Friction torque of ball bearings in vacuum to determine lubricating capability of polytetrafluoroethylene-composition retainer materials
Space environment effect on lubricants and rolling element bearings
Space environmental effect on lubricants and rolling element bearings, comparing evaporative losses of solid and liquid lubricants
Rolling element bearing with stainless steel races and rolling elements and a porous bronze cage successfully operates in ultrahigh vacuum environments at a low torque and with small temperature rise. All components are burnished in molybdenum disulfide.
Transducer assembly measures force in a vacuum environment. The assembly consist of a standard capacitance probe and a torque beam. This transducer can be used in high-pressure as well as in low-pressure environments for static and dynamic force measurements.
