Abstract
The utility model relates to a kind of Self-aligning thrust-bearing, be arranged on transmission main shaft, comprise the plane cylinder be set on described transmission main shaft, to be set on described transmission main shaft and the locking device be positioned at above described plane cylinder, mobilizable fixed block is also arranged with between described plane cylinder and locking device, described plane cylinder top and described fixed block matching part are provided with groove, roll piece is provided with in described groove, described roll piece contacts with described fixed block lower surface, described plane cylinder top and described fixed block matching part are set to arc surface, described fixed block lower surface is also corresponding is set to arc surface, during installation, the arc surface of fixed block is with roll piece contact slide process, because of Action of Gravity Field, arc surface center overlaps with pump spindle center, this thrust-bearing is made to carry aligning function, not only simplify installation steps but also eliminate large-scale detection frock, improve working efficiency.
Description
Technical field
The utility model relates to a kind of bearing, particularly relates to a kind of Self-aligning thrust-bearing.
Background technique
At present, be widely used in thrust-bearing in every field machine driven system, the thrust-bearing such as used in large-sized vertical-type axial-flow pump, vertical guide vane mixed flow pump, mainly contain following two kinds of structures: the first is ball bearing, roller bearing, be generally used for the occasion that thrust that bearing bears is less, high thrust operating mode cannot be met; Another kind is common plane post thrust-bearing, the plane cylinder of this thrust-bearing only bears the effect of end thrust, when bearing is installed, need by large-scale detection frock, such as to the installation of Babbitt thrust-bearing, need to measure the overall concentricity after being connected with pump shaft with adjustment Babbitt thrust-bearing, owing to adopting the water pump of Babbitt thrust-bearing, be mostly the magna pump of more than bore 1400mm, pts wt need be adjusted large, precision prescribed is high, and site environment and equipment are simpler and cruder again, causes very large difficulty to measurement and debugging efforts.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of Self-aligning thrust-bearing, make it have more value in industry.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of Self-aligning thrust-bearing, carries aligning function, simplifies installation steps, improve working efficiency.
Self-aligning thrust-bearing of the present utility model, be arranged on transmission main shaft, comprise the plane cylinder be set on described transmission main shaft, to be set on described transmission main shaft and the locking device be positioned at above described plane cylinder, mobilizable fixed block is also arranged with between described plane cylinder and locking device, described plane cylinder top and described fixed block matching part are provided with groove, roll piece is provided with in described groove, described roll piece contacts with described fixed block lower surface, described plane cylinder top and described fixed block matching part are set to arc surface, described fixed block lower surface is also corresponding is set to arc surface.
Further, the arc surface radius being arranged on described fixed block lower surface is not more than the radius of the arc surface at described plane cylinder top.
Further, described groove was around plane cylinder one week, and described roll piece is covered with described groove.
Further, described roll piece is ball.
By such scheme, the utility model at least has the following advantages: the matching part of plane cylinder top and fixed block is arranged to arc surface, and the lower surface of fixed block also relative set is become arc surface, when mounted, the arc surface of fixed block with roll piece contact slide process, because of Action of Gravity Field, arc surface center overlaps with pump spindle center, make this thrust-bearing carry aligning function, not only simplify installation steps but also eliminate large-scale detection frock, improve working efficiency.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Shown in Figure 1, a kind of Self-aligning thrust-bearing described in the utility model one preferred embodiment, be arranged on transmission main shaft 1, comprise the plane cylinder 2 be set on transmission main shaft 1, to be set on transmission main shaft 1 and the locking device 4 be positioned at above plane cylinder 2, mobilizable fixed block 3 is also arranged with between plane cylinder 2 and locking device 4, in the present embodiment, locking device 4 and fixed block 3 are respectively the first locking nut 4 and the second locking nut 3, plane cylinder 2 top and the second locking nut 3 matching part are provided with groove 5, groove 5 was around plane cylinder 2 one weeks, roll piece is provided with in groove 5, in the present embodiment, roll piece is ball, ball contacts with the second locking nut 3 lower surface, plane cylinder 2 top and the second locking nut 3 matching part are set to arc surface, second locking nut 3 lower surface is also corresponding is set to arc surface, in the present embodiment, the arc surface radius being arranged on the second locking nut 3 lower surface is slightly less than the radius of the arc surface at plane cylinder 2 top, when mounted, the arc surface of the second locking nut 3 is in the process of sliding with ball contact, because of Action of Gravity Field, second locking nut 3 arc surface center overlaps with pump spindle center, re-use the first locking nut 4 afterwards and lock the second locking nut 3.
In sum, the lower surface of plane cylinder 2 top and the second locking nut 3 is set to arc surface by the Self-aligning thrust-bearing that the utility model proposes, when mounted, by being slidably matched of ball and the second locking nut 3 lower surface, because of Action of Gravity Field, the arc surface center of the second locking nut 3 overlaps with pump spindle center, this thrust-bearing is made to carry aligning function, not only simplify installation steps but also eliminate large-scale detection frock, improve working efficiency, in addition, described Self-aligning thrust-bearing applying working condition scope is wide, high thrust can be born, simple for structure, ensure that the stability of assembly.
The above is only preferred implementation of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
