Abstract
The utility model discloses a kind of high-power and high-speed dydraudynamic drive unit sliding bearing that can incline, it is characterized in that: described bearing is made up of the lower tile mounting base (2) connected by connecting bolt (1) and tile mounting base (3), in the inner ring of lower tile mounting base (2) and tile mounting base (3) bearing of composition jointly, 5 tile fragments (4) are connected with by 5 adjusting screw (5), and these tile fragments (4) are circumferentially being uniformly distributed, a tile fragment (4) is had to be positioned at immediately below bearing inner race, and the spherical column cap (6) by being arranged on adjusting screw (5) end between adjusting screw (5) with tile fragment (4) is connected, circular baffle plate (7) is also provided with at the two ends of bearing inner race, and the upper-end surface a of baffle plate (7) is lower than the upper-end surface b of tile fragment (4).
Description
Technical field
The utility model relates to a kind of sliding bearing, particularly a kind of high-power and high-speed dydraudynamic drive unit sliding bearing that can incline.
Background technique
Inclined to sliding bearing in existing high-power, high rotating speed dydraudynamic drive unit, adopt the tile fragment be uniformly distributed in the diagonal directions to support high speed shaft, this structure has a good radial support when centrifugal machine rotates to high speed shaft.But for high-power, high rotating speed dydraudynamic drive unit; because its eccentric part weight is very large; therefore when compressor emergency shutdown; the face deformation of following two pieces of symmetrical tile fragments is easily caused through long-time Action of Gravity Field; easily causing milling and the vibrations of dydraudynamic drive unit of this tile fragment like this when reruning, time serious, also may cause the inefficacy of tilting pad, system-down.In addition, can produce larger centrifugal force when high speed shaft rotates, this centrifugal force can allow the lubricant oil in bearing consume fast and run off, and often needs make-up oil at any time, just may cause serious consequence not in time once supplement.
Summary of the invention
The utility model is the above-mentioned deficiency in order to solve existing for prior art, and proposing one can have stable support when shutting down to high speed shaft, there will not be the high-power and high-speed dydraudynamic drive unit sliding bearing that can incline of shoe deformation situation.
Technical solution of the present utility model is: a kind of high-power and high-speed dydraudynamic drive unit sliding bearing that can incline, it is characterized in that: described bearing is made up of the lower tile mounting base 2 connected by connecting bolt 1 and tile mounting base 3, in the inner ring of lower tile mounting base 2 and tile mounting base 3 bearing of composition jointly, 5 tile fragments 4 are connected with by 5 adjusting screw 5, and these tile fragments 4 are circumferentially being uniformly distributed, a tile fragment 4 is had to be positioned at immediately below bearing inner race, and the spherical column cap 6 by being arranged on adjusting screw 5 end between adjusting screw 5 with tile fragment 4 is connected, circular baffle plate 7 is also provided with at the two ends of bearing inner race, and the upper-end surface a of baffle plate 7 is lower than the upper-end surface b of tile fragment 4.
Compared with the existing technology, tool has the following advantages the utility model:
The high-power and high-speed dydraudynamic drive unit sliding bearing that can incline of this kind of structural type, its structure is simple, design ingenious, rationally distributed, it, for the variety of problems existing for traditional inclined to sliding bearing, makes improvement on the basis of existing technology, obtains a kind of tile fragment distributed architecture that can carry out better support to high speed shaft, it can prevent tile fragment from deforming after dead time is long, ensure that the reliability of sliding bearing; And it also fully takes into account the problem that high-power, high rotating speed transmission device can consume lubricant oil fast, the semi-circumference up and down of bearing inner race is provided with baffle plate, can will be collected in bearing inner race in grease, prevent the variety of problems caused because lubricant oil is very few.Therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.As shown in Figure 1: a kind of power height rotating speed dydraudynamic drive unit sliding bearing that can incline, this bearing is made up of lower tile mounting base 2 and tile mounting base 3 two-part, the two connects as one structure by connecting bolt 1, in the inner ring of this bearing, 5 tile fragments 4 are connected with by 5 adjusting screw 5, and be that ball is connected (end of adjusting screw 5 is provided with spherical column cap 6) in adjusting screw 5 and the joint of tile fragment 4, 5 above-mentioned tile fragments 4 are circumferentially being uniformly distributed, and there is a tile fragment 4 to be in immediately below bearing inner race, circular baffle plate 7 is also provided with at the two ends of bearing inner race, and the upper-end surface a of this baffle plate 7 is lower than the upper-end surface b of tile fragment 4.
The high-power and high-speed dydraudynamic drive unit sliding bearing that can incline of the utility model example, quantity due to tile fragment 4 is 5, and one of them tile fragment 4 is positioned at immediately below bearing inner race to be located, therefore this tile fragment 4 can bear the positive pressure of high speed shaft, high speed shaft is better supported, prevent tile fragment 4 from deforming, and due between tile fragment 4 and adjusting screw 5 be sphere connect, therefore tile fragment 4 can do small rotation when stressed centered by spherical column cap 6, to be adapted to born pressure, can prevent the problem of the stress deformation of tile fragment 4 own from occurring equally,
And the baffle plate 7 being arranged on the circle in bearing inner circumference can block the most lubricant oil in bearing, lubricant oil is allowed to be unlikely to run off fast, in a large number, and due to the upper-end surface b of baffle plate 7 will lower than the upper-end surface a of tile fragment 4, therefore baffle plate 7 also can not affect the normal work of bearing.
