The threaded female head is designed to removably attach to a male threaded structure. A bearing ring with cam followers that engage the track ring to allow the threaded head to be rotated relative to the male threaded structure to attach and remove the threaded head there from. The bearing ring is attached to a hinge arm that allows the removed threaded head to be moved away from the male threaded structure and then rotated about a vertical axis. Direct attachment of the large diameter track ring to the rear of the threaded head moves the center of gravity forward, resulting in the threaded head remaining essentially vertical when it is removed from the male threaded structure and thereby making it easier to reattach to the male threaded structure.

The mounting conditions between the shaft bearing and a rotating part held in the machine shaft bearing, especially a shaft, is varied by a radial adjustment unit having piezo elements. The transfer function of the vibrations, especially the vibrations producing the sound waves, present between the rotating part and the shaft bearing or a component in contact with the shaft bearing, is varied.

    Abstract: A bearing system includes a housing with first and second relief cuts, and a bearing assembly that includes an inner race and an outer race. An adjust screw contacts a preload spring positioned adjacent the outer race. The preload spring exerts a force on the outer race. The outer race includes a first and second edge, and a connecting portion. The first and second edges are positioned adjacent the first and second relief cuts respectively. The connecting portion contacts a bearing bore surface while the first and second edges of the outer race do not contact the bore surface.

  • Patent number: 6312162
    Abstract: An adjustable bearing spacer (12) includes a cylindrical outer body (42) having a first end (44) for abutment with a bearing cone (28) disposed within one end of a hub (10) and an adjustable ring (46) for abutment with an opposite bearing cone (30). The ring (46) is threadingly engaged with the outer body (42) so as to be extendable from an end (48) of the body (42) allowing adjustment of the length of the spacer (12). End (48) is provided with a plurality of evenly-spaced markings. Two of these markings are in the form of small holes into which the prongs of a tool can be inserted. End (58) of ring (46) is also provided with markings in the form of holes into which the prongs of a tool can be inserted. The markings form an indexing scale for providing an indication of the extension in the length of the spacer (12) when the ring (46) is screwed in or out. The degree of extension is calculated as follows E11=1/x.

  • Patent number: 6283637
    Abstract: A method and apparatus for detuning the natural frequency of a rotatable part, which is rotatably disposed in the shaft bearing, and in the case of which the axis of rotation of the rotatable part is arranged axially identically with the axis of rotation of the shaft bearing, as well as to a correspondingly tunable rotatable part. For compensating an axial play and/or a disturbing sound effect, the clamping conditions are changed by a reversible change of the axial course and/or of the axial contact pressure of an axial adjusting unit onto the rotatable part, the axial adjusting unit being manufactured of a piezoelectrically active material.

  • Patent number: 6244751
    Abstract: A bearing assembly adjustable spacer may include an end portion, a deformable portion, a transversely inward face portion, and a transversely outward face portion. The end portion may be configured for generally axial abutment (e.g., with a shoulder portion) at a location about a spindle portion. The deformable portion may allow the spacer to be provided with a desired adjustment (e.g., a preload, an adjustment to an axial dimension of the spacer, and/or a compression of the deformable portion of the spacer). The inward face portion may be generally directed radially relative to an axis of the spacer. Further, the inward face portion may be configured for generally radial abutment (e.g., with a surface portion) at a location about a spindle portion. The outward face portion may have a generally axially curved portion. The curved portion may be largely directed obliquely away from the end portion of the spacer. Also, the curved portion may be configured to interface with a generally axially curved part (e.g.

    Abstract: A fixed bearing for a radial or diagonal flow compressor is guided in a damping bush whose axial position can be fixed by means of a reconciling plate to establish a desired running gap with respect to the compressor housing. The damping bush has a receiving device for a supporting element which rests against the reconciling plate, such that the supporting element and the reconciling plate are removable when the damping bush is disposed in the compressor housing. When the rotor is mounted, the required thickness of the reconciling disk can be determined and this reconciling disk can then be inserted without removing the rotor or the damping bush for the adjustment of the desired running gap.
