  • Patent number: 6814493
    Abstract: In a plain bearing for the transmission of high axial forces and great flexural moments with slight relative movements the one co-operating bearing component has an annular rib which engages into an annular groove provided on the other co-operating bearing component. The annular rib which can be of an outwardly convergent trapezoidal cross-section is provided with anti-friction linings on its free side faces and possibly peripheral faces. The anti-friction linings, like the co-operating bearing component in question, in particular an outer ring carrying the annular rib, can be subdivided segment-like. The segments can then be released individually from their composite assembly and maintained, in particular provided with new anti-friction linings. A preferred use of this plain bearing is the arrangement thereof between a pylon-supported machine head and the pylon head of a wind power installation.

  • Patent number: 5951170
    Abstract: At least two rigid segments of a tapered bearing sleeve are interconnected y deformable elastomeric sections for rotational support of a shaft or pin about a fixed axis established within a housing into which the bearing sleeve is inserted and held therein by an adjustment closure ring under axial pressure of a spring through which radial clearance between the sleeve segments and the shaft varied during transient loading of the shaft, is minimized to reduce vibrational noise and wear.

  • Patent number: 5857396
    Abstract: A slitting machine includes a pair of parallel arbors structured to support a plurality of cutting knives. The arbors are mounted to a head stock and tail stock on the slitting machine. The head stock and tail stock each rotatably support eccentrics which support the end portions of the arbors. Angular contact bearings, such as tapered roller bearings or ball bearings with inclined races, are positioned between the head stock and tail stock and the respective eccentrics and also within the eccentrics between the arbors and the eccentrics. Mechanisms are provided for providing an axial load across all of these bearings to eliminate play and so to accurately position the arbors so that cutting accuracy can be maintained. One such mechanism is a collet/piston supporting the operator's end of the arbors. The collet piston is received in a cylinder to which hydraulic pressure can be applied through a rotary coupling.

  • Patent number: 5560714
    Abstract: A bearing assembly comprises a piston mounted within and capable of reciprocating movement with respect of a fixed bearing shell. The bearing shell is provided with openings for the supply of a bearing medium, such as compressed air, into a clearance between the piston and the bearing shell. The bearing shell is resilient so that as the diameter of the piston increases due to thermal expansion, the diameter of the bearing shell changes to automatically maintain the clearance therebetween.

  • Patent number: 5286116
    Abstract: An improved motor and bearing assembly is provided for use in an axial gap electric motor. The motor and bearing assembly includes a bearing support, bearing cones circumferentially mounted on the bearing support and a rotating bearing member. Each bearing cone has an axial conical surface at one end. The conical surfaces face each other to form a V-shaped cross-sectional groove. The rotating bearing member includes two rotating bearing rings abutting one another, each ring having an angularly disposed surface forming a V-shaped configuration complementary to the V-shaped groove of the bearing cones. The rotating bearing member provides axial and radial support of the rotor of the axial gap electric motor. Each of the bearing cones is axially movable relative to the bearing support, thereby permitting the stator-to-rotor gap and the bearing clearance to be adjusted after final assembly.

  • Patent number: 5251986
    Abstract: A bushing assembly for use in eliminating axial and radial play in a connection joint is disclosed wherein the bushing assembly is comprised of various members which can be interconnected so that it can be assembled as a unit. Although various embodiments of the invention are disclosed, the bushing assembly of the present invention generally comprises first and second concentrically mounted sleeve members which are engaged along oppositely tapered surfaces such that the sleeve members, when axially tightened, are radially expanded. Both of the sleeve members are axially split so as to create a hoop stress which aids in eliminating the axial and radial play and which can increase the fatigue life of the connection joint.

  • Patent number: 5048646
    Abstract: An anti-skid device of the type including an arm, carrying in its outer end a chain-provided pulley that is brought in contact with a vehicle wheel so that the chains are thrown in under the vehicle wheel. The arm is, in its inner end, journaled in a U-shaped or fork-shaped bracket via a short axle that, in its ends, rests in bowl-shaped hemispherical bearings that are threaded into the legs of the bracket. The bearing bowls are pretensioned against the axle. At the apex of the shaft's spherical ends, recesses are made that take-up lubrication grease and, in this way, a point-like contact between the bearing shells and the axle is eliminated.

  • Patent number: 5011306
    Abstract: An assembly and method is provided for properly securing a device such as a bearing, pulley, sheave or the like to a shaft wherein a split tapered adapter is received about the shaft, the adapter having a first end of lesser diameter, a second end of greater diameter, and a tapered surface therebetween, and threads defined about the first end of the adapter, a locknut is in threaded engagement with the first end of the adapter and a device received about the adapter. The locknut has a set of set screws carried therethrough and spaced therearound which are controlled such that the force developed thereby is adequate to clamp the adapter to the shaft and seat the device on the adapter yet is inadequate to move the device toward the second end of the adapter. A second plurality of set screws may be received through said locknut which generate adequate force to move the device up the adapter to achieve a predetermined location of the device.

  • Patent number: 4972732
    Abstract: A tilt telescope steering column comprises a bracket pivotably supporting a housing between first and second pivot limits. The first and second pivot limits may be changed. A pair of screws attach the housing to the bracket and clearance between the screws and the housing is taken up. A tubular member is located within the housing and is axially movable relative to the housing. Axially spaced bearings engage the housing and the tubular member to take up clearance therebetween. A tilt blocking mechanism includes a lock member carried by the housing and movable to a position blocking relative pivotal movement between the housing and the bracket. The lock member is moved against a surface of the housing when the lock member is in its blocking position to take up clearance between the lock member and the housing. A telescope blocking mechanism includes a lock pin which is movable to a position blocking relative axial movement of the tubular member and the housing.
