Detailed description of the invention
Being described further with reference to Fig. 1-Fig. 3 this utility model, by particular specific embodiment, embodiment of the present utility model is described below, the content that those skilled in the art can be disclosed by this specification understands other advantages of the present utility model and effect easily.
Notice, structure that this specification institute accompanying drawings is drawn, ratio, size etc., all only in order to coordinate the disclosed content of description, understand for those skilled in the art and read, it is not limited to the enforceable qualifications of this utility model, therefore not there is technical essential meaning, the adjustment of the modification of any structure, the change of proportionate relationship or size, under not affecting effect that this utility model can be generated by and the purpose that can reach, all should still drop in the scope that the disclosed technology contents of this utility model can be contained;Simultaneously, in this specification cited as " on ", the term such as D score, it is merely convenient to understanding of narration, and it is not used to limit the enforceable scope of this utility model, the change of its relativeness or adjustment, changing under technology contents without essence, when being also considered as enforceable category of the present utility model.
Hereinafter by specific embodiment, adjustment device of the present utility model will be described in detail.
As Fig. 2 shows: thrust-journal plain bearing 1 includes thrust bearing body 11 and bearing holder (housing, cover) 12.
A kind of adjustment device of thrust-journal plain bearing 1, it is mounted on thrust-journal plain bearing 1, this adjustment device includes the support 2 being fixed on described bearing holder (housing, cover) 12, support 2 is provided with for promoting described thrust bearing body 11 and making the screw mandrel 3 of thrust bearing body 11 maintenance level and drive the reciprocating driving device 4 of screw mandrel 3, and driving device 4 is servomotor or motor.
When thrust-journal plain bearing 1 is after installing rotating shaft, thrust-journal plain bearing 1 is under the impact of self gravitation, again because the quality of thrust bearing body 11 is many relative to the quality of journal bearing part weight, and then cause that thrust-journal plain bearing 1 is downward-sloping relative to rotating shaft, that is the centrage a of thrust-journal plain bearing 1 intersects (as shown in Figure 1) with the axial line b of rotating shaft, so servomotor or step motor drive screw mandrel 3 are by thrust bearing body 11 upwards jack-up, and then make the centrage a of thrust-journal plain bearing 1 reach parallel with the axial line b of rotating shaft, lock-bit nut 5 is rotated to the place contacted with support 2, namely the effect of lock-bit is reached, make radial-thrust bearing body 11 centrage level, facilitate the installation of axle. owing to the Internal Spherical Surface of bearing holder (housing, cover) 12 exists bigger assembly pretightening power with the spherical outside surface of bearing body 11, bigger frictional force will be produced when relatively rotating between mating surface, if there is rigging error, then when unit starting, sliding bearing will carry out self-alignment adjustment under the effect of dynamic pressure oil film, the active force overcoming frictional force and produce can act on radially watt local surfaces or thrust bearing shoe valve local surfaces and cause bearing tiling local surfaces directly to contact with rotating shaft and the phenomenon generation of abrasion occurs, this utility model is utilized can effectively to control its rigging error, prevent the generation of above-mentioned tiling concentrated wear phenomenon. when can avoid installing axle, because thrust disc is too big with the thrust face parallel degree deviation of major and minor thrust bearing, the thrust alloy face of major and minor thrust bearing of damaging, or cause the edge of journal bearing part to damage by pressure, when startup of unit and stopping, overcoming radial-thrust bearing body 11 gravity, it is to avoid the bottom of the top of main thrust bearings and secondary thrust bearing, directly contact with thrust disc, cause thrust alloy surface wear, in unit work process, it is to avoid uneven wear is caused because of gravity and the alignment error of radial-thrust bearing body 11 in the thrust alloy face of major and minor thrust bearing.
The described rectangular shape of support 2, support 2 is fixed on the bearing holder (housing, cover) 12 of described bearing by screw 7, play the effect by means of power, wherein screw 7 is hexagon socket cap head screw, and described screw 7 is arranged with locking spring washer 8, make support 2 more stable when fixing, difficult drop-off, be rotatably connected on described screw mandrel 3 lock-bit nut 5, when radial-thrust bearing body 11 centrage level, lock-bit nut 5 is rotated to the place contacted with support 2, makes thrust bearing body 11 fix, namely reach the effect of lock-bit.
Also include the horizon sensor 9 and the controller that are horizontally set on thrust bearing body 11, described controller is microcontroller, described controller electrically connects with horizon sensor 9 and driving device 4 respectively, as shown in Figure 3: when thrust-journal plain bearing 1 is installed, thrust-journal plain bearing 1 is downward-sloping relative to rotating shaft, that is the centrage a of thrust-journal plain bearing 1 intersects (as shown in Figure 1) with the axial line b of rotating shaft, signal is passed to controller by horizon sensor 9, controller controls servomotor or step motor drive screw mandrel 3 by thrust bearing body 11 upwards jack-up, when the centerline of thrust bearing body 11 is in level, namely the centrage a of thrust-journal plain bearing 1 reaches parallel with the axial line b of rotating shaft, so signal is passed to controller by horizon sensor 9, controller controls servomotor or motor stops driving screw mandrel 3, finally locking lock-bit nut 5, complete work immediately, reach the effect that automatization regulates.
It should be noted that the installed surface of horizon sensor 9 installed surface and radial-thrust bearing body 11 completely against, it is impossible to having angle to produce, and horizon sensor 9 axis is parallel with the axis of radial-thrust bearing body 11, two axial lines can not have angle to produce.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, those skilled in the art carries out common variations and alternatives within the scope of technical solutions of the utility model and should be included in protection domain of the present utility model.
