[0002] The inner ring of the fan self-aligning bearing has the function of centering. During the assembly process, the levelness of the inner ring of the bearing is mainly guaranteed. This structure makes it difficult to ensure the levelness of the inner ring during the hoisting process. The original technology uses turnbuckle screws to hoist the outer ring of the bearing. Adjust the overall levelness of the bearing, but it needs to be adjusted back and forth repeatedly, it is difficult to ensure the levelness of the inner ring, the bearing assembly efficiency is low, and even the bearing assembly needs to be reheated

Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0023] Such as Figure 1-3 As shown, a self-aligning bearing for a fan is hoisted, including a hoisting ring 3, a positioning platen 8, a platen screw 4, a locking screw 6, a hoisting point 5, a hoisting rope 10, a turnbuckle screw 7, and a hoisting beam 11.
[0024] The inner ring of the suspension ring 3 is matched with the outer ring 2 of the self-aligning bearing, and the number of the positioning pressure plates 8 is four, which are evenly distributed on the suspension ring 3 . The positioning pressure plate 8 is L-shaped, one end is fixed on the wall of the outer ring of the suspension ring 3, the other end protrudes inward from the upper end of the self-aligning bearing and the end is provided with a pressure plate screw, the pressure plate screw 4 is in phase with the inner ring 1 of the self-aligning bearing Correspondingly; there are four loc...

The invention discloses an aligning bearing lift for a draught fan. The aligning bearing lift for the draught fan comprises a lifting ring, a positioning press plate, a press plate screw, a locking screw, a lifting point, a lifting rope, a turn buckle and a lifting beam, wherein an inner ring of the lifting ring is matched with an outer ring of an aligning bearing, one end of the positioning press plate is fixed on the lifting ring, the press plate screw is arranged at the other end of the positioning press plate, the press plate screw is corresponding to an inner ring of the aligning bearing, the locking screw passed through the lifting ring and extends inward, the lifting point is connected with the lifting beam through the lifting rope, and the turn buckle is arranged in the middle of the lifting rope. The lifting method includes the following steps: (1) screwing the locking screw tightly after the lifting tool is sleeved in the aligning bearing; (2) rough adjusting the aligning bearing to be horizontal by adjusting the turn buckle; and (3) rotating the press plate screw so as to enable the inner ring of the aligning bearing to be in a horizontal state required for assembly. The aligning bearing lift for the draught fan has the advantages of improving assembly efficiency and being convenient to install by rough adjusting levelness of the outer ring of the bearing and fine adjusting the inner ring of the bearing by adjusting the press plate screw.
Description
technical field [0001] The invention relates to a bearing hoisting and a hoisting method, in particular to a self-aligning bearing for a fan and a hoisting method. Background technique [0002] The inner ring of the fan self-aligning bearing has the function of centering. During the assembly process, the levelness of the inner ring of the bearing is mainly guaranteed. This structure makes it difficult to ensure the levelness of the inner ring during the hoisting process. The original technology uses turnbuckle screws to hoist the outer ring of the bearing. Adjust the overall levelness of the bearing, but it needs to be adjusted back and forth repeatedly, it is difficult to ensure the levelness of the inner ring, the bearing assembly efficiency is low, and even the bearing assembly needs to be reheated. Contents of the invention [0003] The object of the present invention is to provide a self-aligning bearing hoisting and hoisting method for a fan to overcome the above-men...
