  • Patent number: 8181305
    Abstract: The invention relates to a windshield wiper device, particularly for a motor vehicle, comprising at least one wiper shaft (10). Prior art windshield wiper devices having predetermined breaking points exist in order to meet the high demands of pedestrian impact protection. However, the risk of these predetermined breaking points rupturing during the operation of the wiper exists in this type of windshield wiper device. In addition it cannot be guaranteed that the predetermined breaking point ruptures in the event of a pedestrian impact. Therefore, in the inventive windshield wiper device, the at least one wiper shaft (10) can be displaced under the action of a force.

  • Patent number: 8167597
    Abstract: A bearing material composition that lines a support includes a combination of a thermoplastic conforming material and abrasive particles which provide a combined effect for remedying the effects due to edge loading that may be caused by misalignment between the bearing and a shaft to which a portion is rotatably mounted. The conforming material may be PTFE such that it does not have a memory and is subject to cold flow and creep. As a result, misalignment problems and edge loading are remedied by the combination of abrasive removal of metal material from the drive shaft at the location of edge loading and creep of the conforming material at the location of edge loading which may provide an overall greater bearing interface surface.

  • Patent number: 8157448
    Abstract: There is a requirement to provide bearings in relatively low speed non continuous situations such as with regards to turnover stands for engine and winding assembly. Previous bearings incorporating rolling elements are relatively expensive and over specified for such activities. By providing annulus members in a bearing cluster upon rocker members such that the annulus members can articulate in order to provide an appropriate bearing. Lubricating oil generally passes between the annulus members in a laminar stack such that the members can radially slide past each other to accommodate for eccentricities in a shaft supported by the bearing.

  • Patent number: 7857522
    Abstract: An oil film bearing assembly rotatably supports the neck of a roll in a rolling mill. The bearing assembly comprises a housing containing a sleeve bearing and a thrust bearing. A circular lock assembly coacts with the thrust bearing to axially retain the bearing assembly on the roll neck. The lock assembly is axially received on and is rotatable into and out of mechanical interengagement with the roll neck. First bearing elements are carried by and project inwardly from the lock assembly to contact a surface of the roll neck at a first location, and second bearing elements project inwardly from the housing to contact an outer surface of the lock assembly at a second location spaced axially from the first location.

  • Patent number: 7851585
    Abstract: The invention relates to polyacetal compositions comprising a mixture of (i) a polyacetal resin, (ii) p-aramid particles and (III) a vinyl-terminated dimethyl siloxane polymer. These compositions are useful in preparing molded articles exhibiting a good balance between high self-lubricating properties and wear resistance, and especially useful in articles that are in motion with respect to other parts they are in contact with.

  • Patent number: 7842399
    Abstract: A sliding bearing element is characterized in that a bearing material that is bonded to the backing is disposed at least at the edges of the backing in form of wires in the circumferential direction and that a soft material is located at least in a space between said wires. At least one intermediate wire can be disposed between the two edge wires generally running in the circumferential direction. The method comprises the following processing steps: providing a strip of steel or any other material having the required degree of strength which forms the backing of the bearing to be produced, bonding at least one wire at each of the two edges of the backing strip, whereat disposing the wires in such a manner that said wires run in circumferential direction generally, and filling out the spaces between the wires with soft material.

  • Publication number: 20100288559
    Abstract: The present invention concerns the down hole motors used in the oil prospecting industry to drive drill bits for drilling the ground at great depths. The down hole motor (1) comprises a drive shaft (5) held in the motor body (3) by an axial thrust bearing (6) and by a radial bearing (7). The radial bearing (7) is a tubular member whose interior surface is coated with an anti-abrasion layer (11) formed by laser-assisted facing directly inside an alloy steel radial bearing body (10). The thickness of the facing layer is then reduced by removing material by means of a cutting tool. This produces a radial bearing (7) that is relatively insensitive to drilling mud and confers great reliability on the down hole motor (1).

  • Patent number: 7832935
    Abstract: A bearing (100) has a contact surface (110) for mating with a rotatable member. The contact surface has a plurality of crystalline grains (120) distributed at random; a plurality of micro-grooves (130) are formed among the crystalline grains; the micro-grooves communicate with each other thereby forming a net. The micro-grooves accommodate lubricant therein so that when the rotatable member rotates, a sufficient lubrication can be obtained between the bearing and the rotatable member. The bearing is formed by machining and then thermally etching a preform which is formed by powder metallurgy.

  • Patent number: 7828482
    Abstract: A plain bearing has two components, each having a bearing surface; the bearing surfaces being in sliding engagement with each other. The bearing may be a spherical plain bearing having an outer ring that has a concave bearing surface and an inner ring that has a convex bearing surface. One of the bearing surfaces comprises a layer comprising tungsten carbide. One component may have spaced-apart seating surfaces for engaging a moving structure and a generally concave interior that includes an internal rib between the seating surfaces. A spherical plain bearing can be made by providing an outer ring and an inner ring includes an internal rib, and disposing the outer ring around the inner ring with the convex bearing surface engaging the concave bearing surface. The bearing may be used in a swashplate assembly.

  • Publication number: 20100269629
    Abstract: A low friction load slot bearing assembly has a ball and an outer race in which the ball is positioned. The outer race includes an inner engagement surface contoured to a shape complementary to an outer surface of the ball, a first slot located in a face of the outer race, a second slot located in the face of the outer race, and a lubricous liner disposed on the inner engagement surface and on surfaces defining the slots. The low friction aspect is imparted to the load slot bearing assembly via the lubricious liner. The ball slidably and rotatably engages the inner engagement surface of the outer race. A load slot bearing system includes a low friction load slot bearing assembly interconnecting two elements. A link apparatus includes a cylindrical member and two low friction load slot bearing assemblies located on or at opposing ends of the cylindrical member.
