20080313888 | Tool for bearings - A bearing tool includes a first ring, whose inner diameter is larger than the outer diameter of the inner ring of the bearing and whose outer diameter is larger than the inner diameter of the outer ring of the bearing; a second ring, which is coaxial with the first ring, has an outer diameter smaller than the inner diameter of the first ring and the inner diameter of the outer ring of the bearing, and has an inner diameter smaller than the outer diameter of the inner ring of the bearing; and a force-exerting part, which provides an action force to change the axial relative position between the coaxial first and second rings. The bearing is coaxially held between the first and second rings, so that one end in the axis of the first ring urges against the opposite surface of the outer ring of the bearing and one end in the axis of the second ring urges against the opposite surface of the inner ring of the bearing. The action of the force-exerting part is mediated by the first and second rings to change the axial relative position between the inner and outer rings of the bearing. | 12-25-2008 |
20080313889 | Universal installation tool for bearings - A universal tool for installing annular parts, components, or devices such as tapered and non-tapered bearings on shafts includes a cap, a tube, and cooperating interchangeable force distributors. A first interchangeable tapered force distributor attaches to the tube and includes a tapered or beveled edge allowing for proper visual alignment with, and isolated force distribution on, the inner race of a tapered bearing. A second interchangeable non-tapered force distributor also attaches to the tube and includes an annular flange with a substantially flat surface that cooperates with the inner and outer races of the ball bearing such that force applied to the cap of the universal tool is evenly distributed around the inner and outer races of the ball bearing. A connector piece can be used to connect two tubes in order to accommodate longer shafts. For a press-through design, a modified cap comprising an external non-tapered force distributor can be substituted when a machine press is used to install the bearing on the shaft. The non-tapered force distributor allows the shaft to extend therethrough and supports the universal tool when it is inverted and secured to the machine press. | 12-25-2008 |
20090265922 | APPARATUS FOR MANUFACTURING HYDRO DYNAMIC BEARING DEVICE METHOD - An apparatus for manufacturing a hydro dynamic bearing device is provided for the finishing treatment of lubricating oil after lubricating the hydro dynamic bearing device.

20100199490 | METHOD AND APPARATUS FOR MANUFACTURING HUB ASSEMBLIES - A method and apparatus for assembling bearings and a stub into a bore of a hub. The apparatus includes a block defining a receiving position for the hub. A feed mechanism arranges plurality of bearings in the form of an annular array. A first mandrel is axially displaceable toward one side of the hub to push the annular array of bearings into the bore of the hub. A second mandrel is axially displaceable toward an opposite side of the hub to push a stub within the annular array of bearings in the bore of the hub. The stub includes at least one outwardly biased detent for retaining the bearings in the hub. | 08-12-2010 |
20110010930 | APPARATUS FOR INSERTING SEAL INTO SLEWING BEARING - Disclosed is an apparatus for inserting a seal into a slewing bearing including a main body and a pressing unit. The main body is fixed to any one of a first ring and a second ring of the slewing bearing. The pressing unit projects from the main body toward a sealing installation position of the other one of the first ring and the second ring. The pressing unit is installed by pressing a seal supplied from the exterior to the sealing installation position toward the sealing installation position as the first ring and the second ring are relatively rotated. Therefore, the seal is installed at the sealing installation position between the first ring and the second ring of the slewing bearing so that the seal of the slewing bearing can be easily exchanged and an exchange operation time of the seal can be reduced. | 01-20-2011 |
20110099799 | ROLLER FINISHING MACHINE - A paint roller finishing machine comprising: a rotatable roller spindle to receive, in use, a paint roller to be finished; a drive unit operably coupled to said spindle to rotate it, in use; two or more finishing tools, selected from the group comprising: a carding tool; a pile shear; a pile beveller; a roller core cutter; and a pile parter; each of said finishing tools being arranged around said roller spindle and configured to be reversibly moveable, in use, from a non-operational position to an operational position in which operational position the tool acts upon a paint roller to be finished; and wherein said drive unit is configured to rotate said spindle, in use, at a plurality of preset rotational speeds. In preferred embodiments, the drive unit runs at speeds in excess of 1000 rpm, and the paint roller finishing machine may have a paint roller loading actuator. | 05-05-2011 |
20110119905 | DEVICE FOR INSTALLING A BOTTOM ROLLER IN A GALANIZING TANK USED FOR THE GALVANIZATION OF A CONTINUOUSLY-MOVING STEEL STRIP - A device for installing at least one roller in a liquid zinc bath in a galvanizing line used for the galvanization of a continuously-moving steel strip has a beam to which a first pair of arms is attached. The first pair of arms bears a bottom roller. The bottom roller is intended to be submerged in the liquid zinc bath towards a bottom roller operation position, relative to the naturally submerged position of the bottom roller, by way of a movement provided together with a first cylindrical bearing attached to each of the two ends of the beam and supporting the first pair of arms. A second cylindrical bearing is attached to each of the two ends of the beam and separate from the first cylindrical bearing on the same beam end section. A push device interacts with at least one of the first and second cylindrical bearings such that, in the operation position, the first and second cylindrical bearings are maintained in a single predetermined plane and such that the first cylindrical bearing is disposed under the second cylindrical bearing at a minimum supporting height along a vertical plane. | 05-26-2011 |
