摘要： A squeeze film damper for a bearing and a vibration damping mechanism capable of damping the vibration of a rolling bearing are provided. The squeeze film damper is small in construction and can be easily made by mass production. The vibration damping mechanism is capable of damping both radial and axial vibrations. A bearing housing 15 is provided with a bearing holding bore 16 of a diameter greater than the outside diameter of the outer ring 14 of a bearing, and an oil hole 19 through which oil is supplied into the bearing holding bore 16. A vibration damping mechanism 1 is formed by inserting a thin, flat sheet 17 provided with slits into an annular space formed between the inner wall of the bearing holding bore 16 and the outside surface of a bearing held in the bearing holding bore 16 so as to surround the bearing. Parts of the thin, flat sheet extending between the adjacent slits serve as elastic beams. The elastic beams center the bearing and support the centered bearing elastically. The vibration of the bearing is damped by the squeeze film effect of an oil film formed by supplying oil into the annular space.

摘要： A bearing cup having a ring and a shoulder extending radially inward from an inner surface of the ring. At least one tang extends axially outward from a first side of the ring. At least one tab extends axially outward from a second side of the ring opposite the first side. And, at least one slot is formed in the second side. The bearing cup prevents the outer race of a conventional rolling element bearing from rotating while allowing the bearing to move in an axial direction. The assembly is designed for use with either a single rolling element bearing or a set of two bearing assemblies or any number of closely spaced bearings. The advantage of the device is that it eliminates spinning of the bearing assembly outer race. The device also prevents frictional sliding between a bearing assembly outer race and a preload spring. Frictional sliding imposed on a bearing outer race can induce galling and subsequently lead to part failure.

摘要： The unitary center support bearing subassembly comprises a bearing over which a plastic bearing housing has been molded while simultaneously molding the plastic bracket insert and joining members which space and fix the distance between the bearing housing and the bracket insert. The joining members are removed or broken prior to molding the overmolded rubber portion, or, if the joining member is flexible, the overmolded rubber portion is molded while maintaining the joining member.

摘要： An improved roller assembly for use in machinery such as round balers is disclosed. The roller assembly of the present invention reduces sensitivity to varying dimensional tolerances on the roller assembly and the structure to which the roller assembly is mounted. At least one elastic member is used to permit the axial position of at least one of the bearings on the roller assembly shaft to vary. Spring washers provide a predetermined, axial force to at least one of the bearings.

摘要： The bearing assembly is intended for application with rotor shafts in turbomachinery. The bearing assembly includes an annular bearing in which the shaft is disposed and a support structure for supporting the bearing. The bearing support is mounted about and radially supports the bearing. The bearing support at least in part defines a squeeze film annulus of the bearing assembly. A plurality of centering elements is associated with the bearing and bearing support and act to center the bearing within the squeeze film annulus. The centering elements are provided at radially spaced locations around the bearing. The centering elements may also be cylinder springs provided at uniformly spaced locations around the bearing. The centering elements may additionally be load cell springs provided at uniformly spaced locations around the bearing. In an alternative embodiment, a singular annular wave spring may be provided in place of the plurality of centering elements.

摘要： A resilient mount (30), such as a center bearing isolator mount includes an inner sleeve (52) into which is molded an elastomer/rubber isolator (60), and an insert (70). These components are prepared as a sub-assembly (50) and axially inserted into the opening of an outer bracket (32), whereby fingers (76) deflect radially during insertion and snap-fit radially outward once received through the bracket opening to preclude disassembly. A lower insertion force is required to assemble the components.
