The utility model discloses can further set up as actuating mechanism includes two screw rods and a swivel nut, and two screw rods are fixed connection respectively on the inner wall of two arc covers, and the screw thread on the screw rod revolves to on the contrary, the swivel nut is located between two screw rods, and the axial both ends of swivel nut form screw-thread fit with two screw rods respectively. By means of the arrangement, the two arc sleeves can be correspondingly driven to be folded inwards or expanded outwards in the radial direction simultaneously by rotating the threaded sleeves under the threaded matching of the threaded sleeves and the two screws.
The utility model discloses still can further set up the lower extreme that sets up to lower adapter sleeve to wide toper structure narrow down. The arrangement is convenient for inserting the lower connecting sleeve, and particularly for some double-row or multi-row cylindrical roller bearings, as the elastic check ring is usually arranged between two adjacent rows of rollers for isolation, the lower end of the lower connecting sleeve is arranged in a conical structure, which is more beneficial to guiding the elastic check ring to the inner ring of the bearing.
The utility model discloses still can further set up to be fixed with the elastic rubber sleeve on the up end of last adapter sleeve. By additionally arranging the elastic rubber sleeve, the whole body formed by the upper connecting sleeve, the lower connecting sleeve and the bearing inner ring has buffer protection at the beginning of stress.
