  • Large diameter polytetrafluoroethylene or like seals
    Patent number: 7040628
    Abstract: A large-diameter PTFE seal. The lip of the seal is made from a long strip of PTFE bound together at the ends with the aid of a patching tape to form a closed loop. The loop is then flanged and placed between an inner and an outer case, together with a rubber-like gasket, and the cases are crimped together, entrapping the lip material between them.

  • Method for mounting a sleeve on a shaft and a sleeve device for such mounting
    Patent number: 7037026
    Abstract: A method for mounting an axially split sleeve provided with an axial slot on a shaft so that a tapering surface on the sleeve cooperates with a tapering bore of a machine member. A flange is axially connected to the sleeve and supports a number of spaced apart tightening devices that are to be urged against the machine member for mutually displacing the machine member and the sleeve to increase the grip between the shaft, the sleeve and the machine member. The method involves positioning the sleeve around the shaft with the annular flange positioned with its tightening devices against the machine member, tightening a first one of the tightening devices which is located at a position diametrically opposite the slot in the sleeve, and thereafter tightening further ones of the tightening devices one by one.

  • Rolling element bearing having starved lubrication conditions
    Publication number: 20060037196
    Abstract: A rolling element bearing comprises an inner ring and an outer ring which are each provided with a raceway, and a series of rolling elements which are in contact with the raceways of each ring. A lubricant film is provided in the contacts between the rolling elements and the raceways, which film forms a lubricant meniscus at the inlet side of each contact. In the bearing starved lubrication conditions prevail. The surface of each rolling element has minute recesses filled with a lubricant quantity, said recesses being flattened in the contact area defined by the contact between the rolling elements and the rings and thereby releasing lubricant at the inlet side of each contact resulting in a displacement of the meniscus further away from said contact. This meniscus displacement results in an increased lubricant film thickness in each contact area, thus improving the lubricating conditions in the bearing.
