摘要:
A spindle motor assembly (18) includes a polymeric motor shaft (20), a polymeric hub (22) to support a rotating disc (24), and a stator (40) disposed in an internal cavity defined by the hub. A resilient snap-in retainer (62) is molded to the motor shaft (20) to hold the hub (22) in place. A surface of the polymeric hub and an opposing surface of the polymeric motor shaft form a hydrodynamic bearing.
摘要:
A bushing comprising a main body that is adapted to be supported by the first member. The main body is comprised of a rigid layer and one or more other layers supported by the rigid layer. One of the layers defines an axial bore that is adapted to receive a pin that movably couples the second member to the first member.

The present disclosure relates to a low friction bearing liner for a solenoid may include a low friction layer. The low friction layer may include a first fluoropolymer matrix component and a first thermoplastic filler component distributed throughout the first fluoropolymer matrix component. The content of the first fluoropolymer matrix component may be at least about 1 wt. % and not greater than about 99 wt. % for a total weight of the first low friction layer. The content of the first thermoplastic filler component may be at least about 1 wt. % and not greater than about 99 wt. % for a total weight of the first low friction layer.
摘要:
Embodiments are directed to solid lubricant assemblies for providing over temperature protection for bearings and gears in rotorcraft systems. A solid lubricant enters a fluid state above a certain temperature and is positioned so that fluid lubricant is applied to the bearings or gears.
摘要:
A bearing system includes a first bearing, the first bearing being annular in shape and defining a ring aperture, the first bearing including a first surface and a second surface, a second bearing being substantially the same in construction to the first bearing, a first surface of the second bearing contacting a second surface of the first bearing, wherein each of the bearings is constructed of nylon MDS.
摘要:
A curvilinear motion rolling guide unit is such that pipe members adapted to form return passages are disposed respectively at undercuts of wings of an arcuate casing, thereby reducing working costs. A slider has a casing and end caps fixed to respective opposite ends of the casing. Pipe members adapted to form return passages are disposed at the respective undercuts formed on the wings of the casing. Cover members have longitudinally extending grooves, respectively, for covering the pipe members. Fitting grooves formed at opposite ends of the grooves of the cover members are fitted to direction changing passages provided in the respective end caps, whereby the cover members are fixed to the end caps.
摘要:
High temperature use of a self lubricating coating material in a foil bearing and part coated with such a material. A material according to the disclosure includes between 50 and 90 wt % of alumina (Al2O3), as well as an oxide selected from the group consisting of titanium oxide (TiO2), chromium oxide (Cr2O3), and a mixture of these. Application to a rotor and/or a thrust disc at least partially covered with such a material.
