Abstract
The utility model discloses a large guide bearing mounting and fixing structure which comprises a bearing seat (1) and a guide bearing (2). An annular groove (7) is arranged on the inner cylindrical surface of the bearing seat (1), a fan-shaped press plate (3) is arranged in the annular groove (7) and fixedly mounted on the bearing seat (1), a groove (6) is formed on the fan-shaped press plate (3), and a connecting key (5) higher than the end face of the guide bearing (2) is arranged between the guide bearing (2) and the bearing seat (1) and extends into the groove (6). The large guide bearing mounting and fixing structure is capable of avoiding bearing failure and simultaneously facilitating the mounting and replacement of the bearing.
Description
Technical field
The utility model relates to a kind of mount fixing structure, particularly relates to a kind of mount fixing structure of large-scale guide bearing.
Background technique
Large-scale guide bearing is widely used in various machineries, especially large-scale vertical diagonal pumps, axial-flow pump, and general the install and fix mode of guide bearing on stator has following two kinds:
1, interference fit is installed: guide bearing itself is simple in structure, and fixation method produces pretightening force by the interference size of bearing support inner cylindrical surface and guide bearing external cylindrical surface, makes bearing when equipment operation, does not produce radial and axial displacement.But trouble bothers when especially changing bearing more during assembling.
2, flanged (FLGD) guide bearing is installed: originally be installed as Spielpassung and install, the flange that is carried by bearing is fixed on the bearing support by double-screw bolt and nut, makes bearing when equipment operation, not produce radial and axial displacement.
General large-scale vertical diagonal pumps and axial-flow pump adopt second kind and install and fix mode.But this kind installs and fixes mode being used for carrying (like seawater) when being corrosive medium, because the corrosive action of medium often causes fastening double-screw bolt and nut to lose efficacy, makes guide bearing generation axial displacement (mainly being the guide bearing of pump foot).Thereby make the pump can not safe and stable operation, the serious pump lower part that makes damages.
The model utility content
The utility model technical problem to be solved provides a kind of guide bearing that can prevent and lost efficacy, and makes the installation of bearing simultaneously and changes the mount fixing structure of easier large-scale guide bearing.
In order to solve the problems of the technologies described above; The mount fixing structure of the large-scale guide bearing that the utility model provides; Comprise bearing support and guide bearing; Inner cylindrical surface at described bearing support is provided with annular groove, in described annular groove, is provided with fan-shaped pressing plate and described fan-shaped pressing plate is fixedly mounted on the described bearing support, has groove on the described fan-shaped pressing plate; Be provided with connecting key between described guide bearing and the described bearing support, the end face that described connecting key exceeds described guide bearing extends in the described groove.
The long radius circumferential position of described fan-shaped pressing plate is provided with two screws, and described fan-shaped pressing plate adopts fastening screw trip bolt to be installed on the described bearing support through described screw.
The minor radius circumference of described fan-shaped pressing plate is provided with two unthreaded holes.
Adopt the mount fixing structure of the large-scale guide bearing of technique scheme, have additional connecting key between guide bearing and the bearing support, at the circumferential position of bearing support, and it can not be moved radially with fixing guide bearing.Groove on the fan-shaped pressing plate is harmonious with outstanding connecting key, and outstanding connecting key mainly is to prevent that fan-shaped pressing plate from making circumferential movement when equipment operation.The auxiliary hole of the using when unthreaded hole that fan-shaped pressing plate is provided with is the dismounting pressing plate.After fan-shaped pressing plate installs, with two Cock screws, be screwed into fan-shaped pressing plate, to make the radially fixing usefulness of fan-shaped pressing plate through two through holes offering on the bearing support.Owing to have additional connecting key between guide bearing and the bearing support, when conveying is corrosive medium (like seawater), can not cause connecting key to lose efficacy, can not make guide bearing produce axial displacement, thereby make pump ability safe and stable operation, the pump lower part is damaged.
In sum, the utility model is that a kind of guide bearing that can prevent lost efficacy, and makes the installation of bearing simultaneously and changes the mount fixing structure of easier large-scale guide bearing.
Description of drawings
Fig. 1 is the utility model structure left view.
Fig. 2 is along A-A line cut-away view among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 1 and Fig. 2; Adopt non-flanged guide bearing 2, and have additional keyway, set up one annular groove 7 and keyway at bearing support 1 inner cylindrical surface at the external cylindrical surface of guide bearing 2; Two through holes are set up in certain radius position at the end face of bearing support 1; Be provided with connecting key 5 in the keyway between guide bearing 2 and the bearing support 1, at the circumferential position of bearing support 1, and it can not be moved radially with fixing guide bearing 2.In annular groove 7, be provided with fan-shaped pressing plate 3, the thickness of fan-shaped pressing plate 3 is highly consistent with annular groove 7, has a groove 6 consistent with connecting key 5 width on the fan-shaped pressing plate 3.Guide bearing 2 is after installing on the bearing support 1, and the length of connecting key 5 will exceed the end face of guide bearing 2, and its size that exceeds should be slightly less than the degree of depth of groove 6.Then fan-shaped pressing plate 3 is packed in the annular groove 7, the groove 6 on the fan-shaped pressing plate 3 is harmonious with outstanding connecting key 5, and outstanding connecting key 5 mainly is to prevent that fan-shaped pressing plate 3 from making circumferential movement when equipment operation.Fan-shaped pressing plate 3 is provided with 4 holes, and two holes on the long radius circumferential position are screw, and two holes on the minor radius circumference are unthreaded hole 8, the unthreaded hole 8 auxiliary hole of using during for the fan-shaped pressing plate 3 of dismounting.After fan-shaped pressing plate 3 installs, with two fastening screw trip bolts 4, be screwed into fan-shaped pressing plate 3, to make the radially fixing usefulness of fan-shaped pressing plate 3 through two through holes offering on the bearing support 1.
