Abstract
The invention discloses a self-aligning thrust bearing for a submerged pump, which comprises a disc-shaped pedestal and at least two thrust bearing blocks uniformly distributed on the circumference of the pedestal; the thrust bearing bocks are composed of bases which are made of metal materials and friction sheets made of high molecular materials; at least one concave waterway is arranged on the surfaces of the friction sheets; a boss is arranged in the middles of the bottom surfaces of the bases; the boss is contacted with the pedestal; and the thrust bearing blocks are provided with clamping mechanisms to fix the thrust bearing blocks on the pedestal. The self-aligning thrust bearing aims at turning a fixing plane type thrust bearing into a self-aligning thrust bearing by changing the structure form of the original design; owing to the design of the boss at the bottom of the thrust bearing, the thrust bearing blocks are inclined to modify the matching precision, so as to remarkably increases the contact area of the thrust bearing blocks and reduce the pressure; the multiple movable friction blocks are synchronously abraded, thereby greatly prolonging the service life of the submerged electric pump. The processing part is simple and easy to realize and is comparatively low in cost; and with application of the self-aligning thrust bearing, the service life of the product is prolonged.
