What is the support method of the thrust bearing ship?

166 Published by admin Jan 23,2019

Method of the thrust bearing ship are mainly divided into rigid strut type, hydraulic strut type and balance block strut type according to the type of strut. In addition, there are elastic pads, springs, pistons, elastic disc posts and the like. details as follows:

1. method of the thrust bearing ship--Rigid strut type (anti-heavy bolt support)
The rigid strut thrust bearing ship generally consists of a thrust head, a mirror plate, a bearing bush, a strut bolt, a method of the thrust bearing ship housing, an oil groove and a cooler. The utility model is characterized in that the thrust bush is supported by the pillar bolt which is spherical on the head, and the thrust bearing ship bush is maintained on the same horizontal plane by adjusting the height of the bolt, so that the force of each tile is uniform. The advantage of the rigid pillar is that the structure is simple and the processing is easy. The disadvantage is that the level is adjusted during installation, the force is not easy to adjust, and the adjustment workload is large. The load of each tile is not balanced during operation (this phenomenon is caused by processing and installation errors and load changes), and is generally applied to medium and small capacity units.thrust ball bearing

2. method of the thrust bearing ship--Hydraulic strut type (elastic tank support)
The hydraulic strut type thrust bearing ship is characterized in that the thrust pad is supported by an elastic oil tank, and each fuel tank is connected by an oil passage and filled with a certain pressure oil. During installation, the height and level adjustment accuracy of each tile surface is not high, and the uneven load between the tiles is balanced by oil pressure. The uneven load of each tile during operation is balanced by the elastic oil tank, so that the force of each tile is even. Therefore, the hydraulic strut type thrust bearing ship has the advantages of automatic adjustment of bearing load, large carrying capacity, simple adjustment, convenient maintenance, small temperature difference between the temperature and temperature, and long life. This type of thrust bearing ship has been used more and more in large units.thrust bearing

3. method of the thrust bearing ship--Balance block strut
The balance block strut type thrust bearing ship uses the upper and lower two rows of balance blocks to overlap each other (the upper and lower balance block contact faces and the lower balance block and the oil pan upper plate contact faces, both of which are in contact with the plane surface), when subjected to force Due to the principle of leverage, the balance blocks move each other, and the force of each tile is automatically adjusted continuously to make the load of each tile uniform. The utility model has the advantages of simple structure, convenient processing and easy installation and adjustment; the disadvantage is that the hinge point (line) with high compressive stress during operation may have sliding friction phenomenon due to the precision of the limit pin, so that the ability to balance the load is unstable. . It was found in the test that the sensitivity of the weight is reduced as the number of revolutions increases. The balance block structure thrust bearing ship has been tested in China for many years, which proves that this structure can adapt to various working conditions of medium and low speed thrust bearings, and the running performance is good.
