In certain embodiments, a method includes positioning a tolerance ring between a bearing assembly and an actuator arm. The tolerance ring is compressed so that the tolerance ring buckles at predetermined weak points to position the bearing assembly relative to the actuator arm.In certain embodiments, an assembly includes a tolerance ring buckle-fitted between first and second annular surfaces, the tolerance ring buckled at designated weak points to position the first annular surface to the second annular surface.

A thermally stable tribological coating is applied to the outer surface of a moveable bearing outer ring in a bearing assembly for an x-ray tube rotating anode and/or the surface of a housing bore of the X-ray tube rotating anode which receives the bearing assembly. If the tribological coating is applied to the outer surface of the bearing outer ring, it is made of a material that is metallurgically incompatible with the material from which the housing containing the bearing is made. The coating includes one or more of the following: Cr, W, Mo, or Nb, or nitrides, carbides, oxides, or sulfides of Cr, W, Mo, or Nb.

A method for monitoring a bearing is disclosed. The method involves positioning a non-contacting bearing isolator adjacent a bearing on a piece of rotating equipment so that at least one operating parameter of said bearing is communicated to said bearing isolator; and, positioning an energy detector within range of said bearing isolator so that said energy detector is able to monitor said at least one operating parameter of said bearing by detecting at least one operating parameter of said bearing isolator.

A guide member has a ring for mounting a pin with friction and articulation and/or sliding capacity. The member is adapted for mounting in the bore of a support. The ring and/or the pin is subjected, at least at its friction surface, to a surface hardening treatment by diffusion or by structural transformation, followed by finishing surface treatment for reducing the tendency to jamming and to reduce the friction coefficient. The friction surface of the ring, comprising its bore, has arrangements acting as a lubricant reserve. The outer periphery of the ring is joined to an element made from a deformable flexible material suitable for being engaged in the bore of the support.

A cam assembly is provided for adjustment of a drill feed guide wear pad. The cam assembly has an eccentric bushing with a shank portion extending circumferentially about a first axis and defining a bore along a second axis. The second axis is generally parallel and offset from the first axis. The bushing has a head portion extending from the eccentric bushing portion, with the bore extending though the head portion. The bushing is sized for insertion into an aperture of a drill feed guide wear pad, and is rotatable causing the shank portion to engage the aperture of the wear pad to provide a camming action to position the wear pad relative to a drill feed guide. The head portion is shaped to interact with a tool for rotating the bushing.

A rotary wing aircraft bearing for providing constrained relative motion between a first rotary wing aircraft member and a second rotary wing aircraft member. The bearing includes an elastomeric mold bonded laminated subassembly, the elastomeric mold bonded laminated subassembly including a plurality of mold bonded alternating layers of interior nonelastomeric shim members and interior elastomeric shim members, the interior elastomeric shim members including a first laminate end elastomeric shim and a distal second laminate end elastomeric shim. The first laminate end elastomeric shim has a first side mold bonded to a first end interior nonelastomeric shim member and a second side mold bonded to a first metal first laminate end structural bond shim. The distal second laminate end elastomeric shim having a first side mold bonded to a distal second end interior nonelastomeric shim member and a second side mold bonded to a second metal distal laminate end structural bond shim, the elastomeric mold bonded laminated subassembly having an elastomeric subassembly tensile strength ESTS between the first metal first laminate end structural bond shim and the second metal distal laminate end structural bond shim. The rotary wing aircraft bearing includes a first end bearing connector first metal member for connecting to the first rotary wing aircraft member, a first end structural chemical adhesive epoxy post-elastomeric mold bond between the first end bearing connector first metal member and the first metal first laminate end structural bond shim, the first end structural epoxy bond having an elongation of at least 11% and a first end tensile strength FETS with FETS≧ESTS.
摘要:
A device for axially fixing a rotatable part of a wheel bearing to a rotatable drive part of a drive shaft. The device provides a mounting auxiliary which enables inspection of the tooth position of a spur gearing. The device has a substantially cylindrical or ring-shaped attachment part and a locking element. Either the substantially cylindrical or ring-shaped attachment part is provided for attachment on the rotatable drive part, and the locking element is provided for locking to the rotatable wheel bearing part, or the substantially cylindrical or ring-shaped attachment part is provided for attachment to the rotatable wheel bearing part and the locking element is provided for locking to the rotatable drive part.
摘要:
A low-friction device having a moving interface comprising first and second members. Each of the members has a maximum dimension of about 100 μm or less between any two points. At least the first member is formed of diamond and the first and second members are in sliding contact or meshing contact.

A guide apparatus including a track rail and a moving block is free from the possibility of foreign matter entering the moving block through the gaps between the side surfaces of the track rail and the inner side surfaces of the moving block even in an environment where many fine dust particles are flying.A guide apparatus has a track rail and a moving block 20 relatively movably attached to the track rail with rolling elements interposed therebetween. The rolling elements recirculate through rolling element recirculation passages. Foreign matter entry preventing plates 34 are provided so that their respective distal ends longitudinally contact the opposite side surfaces of the track rail to close the gaps between the side surfaces of the track rail and at least the inner side surfaces of skirt portions on both sides of a moving block body 21 and the inner side surfaces of end plates of the moving block 20.
