Abstract
The utility model discloses a supporting structure of a thrust bearing, comprising a sleeve support fixed on a lower rack and a strut bolt arranged in the sleeve support, wherein the strut bolt is provided with an axial through hole along the axis; the axial through hole is internally provided with a measuring rod and a displacement sensor below the measuring rod; the displacement sensor is sheathed and fixed at the lower end of the axial through hole by a fixed hole sleeve; parts of the fixed hole sleeve and the displacement sensor extend out of the axial through hole; and the part of the fixed hole sleeve, extending out of the axial through hole, is also provided with locking screws for fixing the displacement sensor which is also connected with an electronic displacement meter by leads. The supporting structure can monitor and adjust stress accurately to lead the stress of all thrust tiles to be balanced, thus greatly improving the operation stability and prolonging the service life.
Description
Technical field
The utility model relates to a kind of supporting structure of thrust-bearing.
Background technique
The thrust-bearing of vertical hydrogenerator is the key position of carrying hydraulic generator rotating part weight and hydraulic thrust, plays an important role in the hydraulic generator unit, is called as the heart of vertical hydrogenerator.At present in the installation of vertical hydrogenerator, the supporting structure of existing thrust-bearing mainly is by being packed in the sleeve bearing on the lower bearing bracket, mounting column bolt in the sleeve bearing supports a thrust bearing shoe valve by propping up stud, and needs height and space by adjusting a stud adjusting.The effect of part supporting structure in order to reduce the bearing shell distortion and to avoid bearing shell middle part stress to concentrate also increases a pallet below thrust bearing shoe valve.The supporting structure of existing thrust-bearing exists to control accurately and effectively to be adjusted stressedly, causes each thrust bearing shoe valve unbalance stress, causes the wearing and tearing tile kilning easily.
The model utility content
At the problem that above-mentioned prior art exists, the utility model provides a kind of supporting structure of thrust-bearing, and it is stressed accurately to monitor adjustment, makes each thrust bearing shoe valve stress equalization, improves operation stability and life-span greatly.
The technical solution of the utility model is: a kind of supporting structure of thrust-bearing, comprise the sleeve bearing that is fixed on the lower bearing bracket, be located at the stud in the sleeve bearing, be provided with an axis through-hole at a stud along axis, be provided with a displacement transducer of a measuring rod and measuring rod below in the axis through-hole, displacement transducer is fixed in the axis through-hole lower end by the socket of fixed hole cover, and fixedly borehole jack and displacement transducer partly stretch out axis through-hole, fixedly borehole jack projecting shaft heart throughhole portions also is provided with the lock screw of fixed displacement sensor, and displacement transducer also connects the electron displacement meter by lead-in wire.
The beneficial effects of the utility model are: in the studio shaft heart through hole displacement transducer and measuring rod are installed, the whole axial forces of unit are applied on the stud by thrust bearing shoe valve, thereby produce compressive strain with top at the pillar bolt thread, drive measuring rod simultaneously to bottom offset, give displacement signal of displacement transducer, and on the electron displacement meter, demonstrate corresponding stud distortion numerical value, and numerical value carries out the height adjusting to each stud in view of the above, thereby make each thrust bearing shoe valve stress equalization.This design has reduced the difficulty of the stressed adjustment of thrust bearing shoe valve, has improved the stressed validity of thrust bearing shoe valve, can carry out effective monitoring to the thrust bearing shoe valve stressing conditions when unit operation simultaneously, improves operation stability and life-span greatly.
