摘要： A bearing cage for a roller bearing includes first and second axially spaced ring elements and a plurality of bridges extending therebetween and defining a plurality of pockets each configured to receive a roller element. Each of the bridges has first and second circumferential side faces that form contact surfaces for the rollers. Furthermore, each of the contact faces has an embossing depth greater than 50% of the radial thickness in a radially outer direction.

摘要： A method for improving measurements when performing an alignment of the shafts of a first machine and a second machine includes providing to an algorithm a first value measured between two points of the first and second machines, providing to the algorithm a second value measured between one of the two points of the first or second machine and a front foot of the first or second machine, providing to the algorithm a normalized value or standard value between the front feet and the back feet of the first or second machine, and extracting from the algorithm values to compensate for or correct the horizontal and vertical misalignments.

摘要： A flanged inner ring of a wheel hub unit includes a flange extending transverse to a central axis of symmetry and having a plurality of fixing holes for attaching a wheel. The flanged inner ring also includes a continuous tubular body projecting axially from the flange, the continuous tubular body having a plurality of polygonal recesses. The polygonal recesses reduce weight of the wheel hub unit and improve water drainage from the wheel hub unit.

摘要： An imaging system is for recording images of a bearing raceway and includes a platform having a surface sized to receive the bearing ring and an optical imager having a lens. A positioner secures the optical imager or a reflector oriented to reflect light to the optical imager lens and locates the optical imager lens or the reflector axially between first and second axial ends of the raceway and facing generally toward the raceway. A motor rotates the platform or the positioner relative to the other one of the platform and the positioner. A processor operates the optical imager and the motor such that the optical imager takes a series of images about the entire perimeter of the bearing raceway. The processor also indexes each image to a separate one of a plurality of arcuate segments of the raceway and constructs a panoramic image of the raceway.

摘要： A method of forming a bearing assembly includes providing a bearing unit configured to support a rotatable component relative to a stationary component, the bearing unit including a stationary bearing ring and a rotatable bearing ring, and overmolding a material onto a portion of a radial surface of the stationary bearing ring, the portion being less than an entire radial surface of the stationary bearing ring, for example less than 75% of the entire radial surface of the stationary bearing ring, to form the stationary component.

摘要： A plain bearing having an outer ring and an inner ring, the outer ring and the inner ring providing respectively an inner surface and an outer surface intended to cooperate with each other for the relative movement of the outer and inner rings, the inner surface of the outer ring and the outer surface of the inner ring each including a coating including at least one layer. The hardness of the coating on the inner surface of the outer ring is less than the hardness of the outer ring, and the hardness of the coating on the outer surface of the inner ring is greater than the hardness of the inner ring.

摘要： A cooling system includes a refrigerant cycle having a compressor unit for compressing gaseous refrigerant, a condenser unit for condensing gaseous refrigerant to liquid refrigerant, an optional economizer unit for reducing pressure of the refrigerant and partially evaporating the liquid refrigerant, and an evaporator unit for evaporating the liquid refrigerant to gaseous refrigerant. The refrigerant is cycled from the compressor unit to the condenser unit, from the condenser unit to evaporator unit, and back to the compressor unit. The compressor unit includes at least one bearing assembly and a lubrication cycle providing liquid refrigerant to lubricate the bearing assembly. The lubrication cycle has a lubricating refrigerant supply line, branched from the condenser unit or from the economizer unit to the bearing assembly, and connected to an injection device(s) for introducing lubricating refrigerant into the bearing assembly. A vapor separating unit separates gaseous lubricating refrigerant from liquid phase lubricating refrigerant.
