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 insert support device of bearing shell.
Background technique
In the rotor-bearing system of the rotating machineries such as existing steam turbine, blower, usually between bearing shell and bearing support, be provided with the device of inserting, comprise bolt and be connected to anchor plate and the some pads on bearing shell by bolt.Its Main Function is: by reducing or increase the center absolute altitude that pad is adjusted rotor.Yet existing this stiff support device, because system rigidity is relatively good, when rotor is subject to External Force Acting or bearing support forced vibration, can't discharge the dynamic buckling power produced because of deformation of the oil film, tend to cause the Relative Vibration between rotating shaft and bearing shell to increase, affect the stable operation of system.
Summary of the invention
The insert support device 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, extends bearing shell working life.
The solution of the present invention is achieved in that a kind of insert support device of bearing shell, be located at the elastic device between bearing shell and bearing support for propping up, reaching by bolt the anchor plate, elastic cushion block and the some packing rings that are connected with bearing shell by bolt forms, it is characterized by: described anchor plate is for covering the shape parts, its end face is the arc matched 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; Described 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, outer arc is less than the anchor plate endoporus, inner arc coordinates 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 the bearing shell boss height, and the total height after guaranteeing it and anchor plate coordinating is greater than the height of anchor plate.
As preferably, the spherical surface of described anchor plate end face for matching with the inner hole of bearing seat spherical zone.
The invention has the beneficial effects as follows: due to the employing of said apparatus, make support unit not only can radially adjust and can freely swing, facilitated the middle adjustment of looking for of bearing shell; And the employing of elastic member, elastic damping, tempered oil film are carried out in vibration intrinsic to system or External forcing; 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, extend bearing shell working life.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In 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: packing ring 1 is placed on to the bottom groove in the bearing shell 3 set holes of cylindrical, then loads onto respectively elastic cushion block 4 and anchor plate 2, then load onto bolt 5, and make bolt countersunk head and counterbore bottom gapped.Because anchor plate 2 can freely swing, therefore by the increase of the quantity to packing ring 1 or minimizing, adjust the center absolute altitude and be very easy to.Due to; the yielding support of elastic cushion block 4; effectively discharged the oil film elastic deformation force who causes deformation of the oil film to produce because of the external world or shaft vibration; and this can make the load of bearing shell reduce because of dynamic yielding support power that vibration produces; thereby 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, extend bearing shell working life.
