Thrust bearing support

2018 - thrust bearing support way 09 - 29 pillar type thrust bearing according to the different main divided into rigid pillar type, hydraulic prop type, balance block pillar type 3 kinds. In addition to elastic cushion, spring, piston, elastic disc pillar type, etc. Specific as follows: 1. Rigid pillar type ( Resistance to heavy bolt supporting) General by rigid pillar type thrust bearing thrust head, mirror plate, bearing and pillar of bolts, bearing, oil tank and cooler. Its characteristics are the pillar of thrust tile by head for the spherical bolt support, by adjusting the height of the bolt and keep the bearing in the same horizontal plane, in order to make the machine to receive strength evenly in each segment. Rigid pillar type advantage is simple structure, easy processing. The disadvantage is that sort of horizontal installation, force not easy alignment, adjust the larger workload. Run time of each segment load imbalance ( This phenomenon is caused by machining and installation error and load change) , generally used in medium and small capacity unit. 2. Hydraulic prop type ( Elastic supporting tank) Hydraulic prop type characterized by thrust tile by the elastic oil tank of thrust bearing support, connected to the tank by the oil duct and filling the pressure oil. When installation, the tile surface height and level adjustment accuracy is not high, the uneven load of each tile hydraulic balance. Runtime uneven load by the elastic oil tank of the equilibrium, make the machine to receive strength evenly in the tile. Therefore, hydraulic prop thrust bearing can automatically adjust the bearing load, large bearing capacity, simple adjustment, convenient maintenance, poor tile [small, long service life, etc. Now this type of thrust bearing in large units, has been more and more applications. 3. Pillar type counterweight balance block pillar type thrust bearing is to use the up and down two rows of counterweight overlap each other ( Upper and lower contact area and the counterweight of balance block and oil pan plate on the contact surfaces, both for the cylinder with plane contact) , when stress, because of the lever principle, balance block action each other, the stress of the continuous automatic adjustment of each tile, make each tile to achieve uniform load. It has the advantage of simple structure, easy processing, easy to install; The disadvantage is that compressive stress at runtime high hinge pivot ( Line) Because of the limit pin will appear the phenomenon of sliding friction, the influence of accuracy which balanced load capacity is not stable. Found in the experiment, the counterweight sensitivity increased with the increase of rotational speed reduced. Balance thrust bearing block structure in our country after years of running test, proved this structure under various working conditions can be adapted to medium and low speed of the thrust bearing, running performance is good.
