Kugelförmiges Lager und Montageverfahren

摘要

To make a spherical bearing (10), an outer ring (12) is formed with counterbores (20, 22) at the ends thereof, disposed along a common axis (24) and separated by a radially inwardly extending keel portion (26). A polymer liner (16, 18) is inserted into each end of the outer ring (12) into abutment with the keel portion, the polymer liners being preformed with spherically concave inner surfaces (38, 40) conforming to a ball part (14) entrapped therebetween. Portions (48) of the outer ring are then deformed by upset forming over portion (46) of the polymer liners to lock the polymer liners in position. An electrical sensor can be provided for indicating failure of the polymer liners.
