Further, described radial bearing shell is provided with the first card column, and described thrust pad is provided with the first groove and the second groove, the first card column and the first groove clamping.
Further, the number of described thrust pad is 8.
Further, described nozzle is provided with the 3rd card column of cylindrical shape, and described thrust pad is provided with the 3rd groove and the 4th groove, described 3rd card column respectively with the 3rd groove of thrust pad and the 4th draw-in groove clamping of adjacent thrust tile fragment.
Further, described nozzle comprises oil inlet hole and at least one oil outlet, and inlet hole is communicated with oil outlet.
Further, the number of described oil outlet is 6, and six described oil outlet annular arrays are on nozzle.
Further, described support block is made up of alloyed steel, and heat-treats.
Contrast the deficiencies in the prior art, the beneficial effect that the technological scheme that the utility model provides is brought: 1. the utility model adopts 8 nozzles of annular array, and 8 nozzles spray lubricant oil simultaneously, makes rotating shaft be subject to oil evenly.Lubricant oil is directly ejected on thrust button by nozzle, is conducive to the formation of dynamic pressure oil film, effectively can reduce the power consumption of bearing, can regulate oil inlet quantity by the nozzle changing different pore size.2. the utility model is by the first card column and the first groove clamping, 3rd card column is stuck on the 3rd groove of thrust pad and the 4th draw-in groove of adjacent thrust tile fragment simultaneously, make thrust pad reliably spacing on radial bearing shell, do not come off, add the efficiency of assembling and dismounting.3. thrust pad of the present utility model is formed by inlaying support block in tile fragment body, wherein the bottom plane of support block is spheric structure, therefore thrust pad can adjust gradient automatically according to the change of the rotating speed of axle and thrust load, to adapt to different load, rotating speed, the resiliently deformable of axle and deflection, set up state of liquid friction.The large, medium and small profile shaft that load or speed often change holds and all share, most widely used in large size bearing.

Embodiment
With reference to Fig. 1-Fig. 8, the utility model is described further.
A kind of thrust bearing, comprise radial bearing shell 1, described radial bearing shell 1 circular array shows several thrust pads 2, nozzle 3 is provided with between two thrust pads 2 of arbitrary neighborhood, be provided with support block 4 between thrust pad 2 and radial bearing shell 1, described support block 4 comprises bottom 41 and the columned fixing part 42 of spherical shape, and described thrust pad 2 is provided with the circular trough 21 with fixing part 42 adaptation, described fixing part 42 is connected with circular trough 21, conflicts with radial bearing shell 1 and be connected in described bottom 41.
Thrust pad 2 is formed by inlaying support block 4 in tile fragment body, wherein the bottom plane of support block 4 is spheric structures, therefore thrust pad 2 can adjust gradient automatically according to the change of the rotating speed of axle and thrust load, to adapt to different load, rotating speed, the resiliently deformable of axle and deflection, set up state of liquid friction.
Further, described radial bearing shell 1 is provided with the first card column 11, and described thrust pad 2 is provided with the first groove 22, first card column and the first groove clamping.
By the first card column and the first groove clamping, the 3rd card column is stuck on the 3rd groove of thrust pad and the 4th draw-in groove of adjacent thrust tile fragment simultaneously, makes thrust pad reliably spacing on radial bearing shell, does not come off, and adds the efficiency of assembling and dismounting.
Further, the number of described thrust pad 2 is 8.
Be provided with nozzle 3 between two thrust pads 2 of arbitrary neighborhood, therefore, adopt 8 nozzles, 3,8 nozzles 3 of annular array to spray lubricant oil simultaneously, make thrust button be subject to oil evenly.Lubricant oil is directly ejected on thrust button by nozzle 3, is conducive to the formation of dynamic pressure oil film, effectively can reduce the power consumption of bearing, can regulate oil inlet quantity by the nozzle 3 changing different pore size.
