Abstract
The invention relates to an insert support device of a shaft bush, belonging to the technical field of sliding bearings of mechanical products and being an elastic device supported and arranged between the bearing bush and a bearing seat. The insert support device comprises a bolt, a support block connected with the bearing bush through the bolt, an elastic cushion block and a plurality of gaskets. The insert support device has the advantages that: due to the adoption of the device, a support part can be radially regulated and can freely swing so as to be convenient for centering regulation of the bearing bush; ad due to the adoption of the elastic part, inherent or externally-forced vibration of the system is subjected to elastic damping, thus an oil film is protected, when a rotor generates disturbance, the instability of the oil film is effectively reduced, the amplitude of the rotor in the whole operation speed range is reduced, the stability of the system is improved, and the service life of the bearing bus is prolonged.
Description
Technical field
The invention belongs to the sliding bearing technical field of machinery product, relate in particular to a kind of bearing device of inserting of bearing shell.
Background technique
In the rotor-bearing system of rotating machineries such as existing steam turbine, blower, between bearing shell and bearing support, be provided with the device of inserting usually, comprise bolt and be connected anchor plate and some pads on the bearing shell by bolt.It mainly acts on: adjust the centre of rotor absolute altitude through reducing or increase pad.Yet existing this stiff support device; Because system rigidity is relatively good, when rotor receives external force effect or bearing support forced vibration, can't discharge the dynamic buckling power that produces because of the oil film distortion; Tend to cause the relative vibration between rotating shaft and bearing shell to increase, influence the stable operation of system.
Summary of the invention
The bearing device of inserting that the purpose of this invention is to provide a kind of bearing shell, it can effectively reduce the amplitude of rotor in the whole service velocity range, improves the stability of a system, prolongs bearing shell working life.
Scheme of the present invention is achieved in that a kind of bearing device of inserting of bearing shell, is located at the elastic device between bearing shell and the bearing support for propping up, and forms by bolt and by anchor plate, elastic cushion block and some packing rings that bolt links to each other with bearing shell; It is characterized by: said anchor plate is for covering the shape parts; Its end face is the arc that matches with inner hole of bearing seat, and establishes bolt mounting holes at curved end, and its cylindrical is less than the set hole of bearing shell cylindrical; The endoporus center is provided with small boss, and raised head face is spherical; Said elastic cushion block is that elastic material is made; U shape parts for the intermediate portion of lid shape parts; End face is provided with and the close-fitting concave spherical surface of anchor plate endoporus boss spherical end surface, and outer arc is less than the anchor plate endoporus, and inner arc cooperates with the cylindrical of the bottom boss in the set hole of bearing shell cylindrical; And its inboard groove degree of depth is greater than bearing shell boss height, and the total height after guaranteeing it and anchor plate cooperating is greater than the height of anchor plate.
As preferably, the spherical surface of said anchor plate end face for matching with the inner hole of bearing seat spherical zone.
The invention has the beneficial effects as follows: because the employing of said apparatus, make support unit not only can radially adjust and can freely swing, made things convenient for the middle adjustment of looking for of bearing shell; And the employing of elastic member, elastic damping, tempered oil film are carried out in the intrinsic or extraneous vibration that forces to system; When rotor generation disturbance, effectively reduce the unstability power of oil film, reduce the amplitude of rotor in the whole service velocity range; Improve the stability of a system, prolong bearing shell working life.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, packing ring, 2, anchor plate, 3, bearing shell, 4, elastic cushion block, 5, bolt.
Embodiment
Below in conjunction with accompanying drawing, technological scheme of the present invention is further described:
As shown in Figure 1: as packing ring 1 to be placed on the bottom groove in the set hole of bearing shell 3 cylindricals, to load onto elastic cushion block 4 and anchor plate 2 more respectively, load onto bolt 5 then, and make bolt countersunk head and counterbore bottom gapped.Because anchor plate 2 can freely swing, therefore increase or reduce and adjust the center absolute altitude and be very easy to through quantity to packing ring 1.Because; The yielding support of elastic cushion block 4 has discharged the oil film elastic deformation force who causes the oil film distortion to be produced because of the external world or shaft vibration effectively, and this can make the load of bearing shell reduce because of dynamic yielding support power that vibration produces; Thereby the thickness and the rigidity of oil film have effectively been protected; Reduce the amplitude of rotor in the whole service velocity range, improve the stability of a system, prolong bearing shell working life.
Claims (3)
1. the bearing device of inserting of a bearing shell is located at the elastic device between bearing shell and the bearing support for propping up, and forms by bolt and by anchor plate, elastic cushion block and some packing rings that bolt links to each other with bearing shell; It is characterized in that: said anchor plate is for covering the shape parts; Its end face is the arc that matches with inner hole of bearing seat, and establishes bolt mounting holes at curved end, and its cylindrical is less than the set hole of bearing shell cylindrical; The endoporus center is provided with small boss, and raised head face is spherical;
2. the bearing device of inserting of a kind of bearing shell as claimed in claim 1; Said elastic cushion block is that elastic material is made, is the U shape parts of the intermediate portion of lid shape parts, and end face is provided with and the close-fitting concave spherical surface of anchor plate endoporus boss spherical end surface; Outer arc is less than the anchor plate endoporus; Inner arc cooperates with the cylindrical of the bottom boss in the set hole of bearing shell cylindrical, and its inboard groove degree of depth is greater than bearing shell boss height, and the total height after guaranteeing it and anchor plate cooperating is greater than the height of anchor plate;
