Abstract
The utility model relates to a sliding bearing load sensor of the technical field of the mechanical device operation, comprising an elastomer, strain foils and a sealed end cover. The bottom of the elastomer in the shape of a column with a spherical surface forms a disc shape, the outer side of the elastomer is provided with two platforms, the elastomer is provided with a long through hole, deep blind holes are arranged between the through hole and the top of the elastomer, and a shallow blind hole is arranged between the two deep blind holes which are pasted with the strain foils. The utility model has the advantages of strong anti-lateral force, high precision, large rigidity, simple structure and easy sealing performance.
Description
The utility model belongs to plant equipment operation technique field, further belongs to the special-purpose force cell of monitoring sliding bearing load in the large rotating machinery operating condition monitoring and fault diagnosis technical field.
At present, in the direct method of testing of large turbo-type generator group bearing load a kind of bearings force method is arranged.It is to utilize the force cell that is installed between bearing and the bearing seat directly to measure the method for testing of bearing load, the gordian technique of this method is a force cell, because the specific (special) requirements of large turbo-type generator group bearing arrangement, all kinds of dynamometry of Xiao Shouing and LOAD CELLS all can not be applied to its four monitoring that watt sliding bearing loads of can inclining in the market.
The purpose of this utility model is to provide a kind of can incline force cell of watt sliding bearing and other similar bearing load of large turbo-type generator group four of monitoring.
The utility model comprises elastic body, foil gauge and end cover, elastic body is that the top is the cylindrical of sphere, the elastic body bottom is discoid, the elastic body outside is symmetrily processed with two platforms, have a long through-hole with elastic body side plane and the bottom disc intersection place of paralleling between elastic body bottom disc and the top, between through hole and top, elastic body platform side line of symmetry both sides have corresponding in twos dark blind hole, midpoint area is pasted foil gauge on the separated time in the deep blind-hole bottom planar horizontal, between two dark blind holes of each side of elastic body a shallow blind hole is arranged, a small through hole is arranged at shallow blind hole bottom.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
Fig. 2 is a vertical view of the present utility model.
The elastic body 1 of sensor is formed by block of metal materials processing, and its top is a sphere shape 2, the midpoint area support load of sphere; Sensor base is a disc-shape 3, and sensor is laid steadily; The sensor profile is a right cylinder, so that match with bearings pad mounting hole; Sensor elastomer 1 both sides have a platform 4 respectively, are a long narrow through hole 5 above bottom disc 3; Form a beam between sensor top 2 and the long narrow hole 5, in twos to four dark blind holes 6 should be arranged, paste 9, two pairs of blind holes of foil gauge on the plane, bottom of each blind hole and make sensor top beam form the shear beam of middle part loading blocks and both sides on the two sides of beam; Loading blocks both sides, sensor middle part are between 7, two shallow blind holes of two shallow blind holes a small through hole 8 to be arranged, and shallow blind hole transverse plane is pasted connection terminal 10, and small through hole is used to guide connecting line between foil gauge; The sensor front-back has four threaded holes 11 respectively, is used to install end cover.
The utility model is the direct test that can incline watt sliding bearing load to four, rather than the reckoning value under many assumed conditions, so be expected to obtain higher measuring accuracy and confidence level, can realize large turbo-type generator group bearing load on-line monitoring easily.Sensor itself is exactly a part of bearing arrangement, does not change the structure of bearing, and is easy for installation, adaptability is strong, does not influence the runnability of bearing.Sensor is shearing sensor, and lateral force resistance is strong, precision is high, rigidity is big, and simple in structure, is easy to sealing.
