The utility model is achieved in that as shown in Figure 1, and it comprises bearing support, lining, thrust bearing, length end cap, back-up ring and length sleeve, it is characterized in that the bearing support I is installed on the pedestal of filmatic bearing test stand by through hole 11,11 '.The lining II of tubulose is installed in the axis hole of bearing support I, left end in the bearing support I is equipped with short end lid III, right-hand member in the bearing support I is equipped with thrust bearing VI, back-up ring IX and long end lid V successively, is separately installed with long sleeve VII and short sleeve VIII about the back-up ring IX; The structure characteristic of bearing support I is shown in Fig. 2,3, the up and down top of shaft hole inner wall center line is shaped with respectively dynamic pressure oil hand-hole 1 and static pressure oil hand-hole 6, have left and right oil groove 3,3 ' on the two ends, the left and right sides of wall within it, left and right oil groove 3,3 ' bottom have left and right spill port 7,7 '; The structure of lining II is to be shaped with dynamic pressure on the top tube wall of center line to enter oilhole 14 and dynamic pressure oil pocket 12, is shaped with static pressure oil hand-hole 15 and static-pressure oil chamber 13 on the bottom tube wall of center line; Short end lid III shaft hole inner wall on have an annular left and right oil groove 16,16 ' be connected with left and right spill port 17,17 ' respectively; Having left and right oil groove 18,18 ' on the shaft hole inner wall of long end lid V is connected with left and right spill port 19,19 ' respectively; The thrust bearing VI is ring part, and the left and right oil groove 20,20 ' that is shaped with annular at left and right end face is communicated with dynamic pressure oil hand-

hole

25,22 respectively; The structure of back-up ring IX is a ring spare, has circular groove 27 on the outer circumference face, has circular groove 26 on its right end face.

Advantage of the present utility model and good effect be have thrust function quiet-hydrodynamic kelmet, overall structure is simple, structure function is complete, lubricating oil path is reasonable in design, can satisfy fundamental research and the experimental research of all kinds of filmatic bearings.
