Description
Technical field
The utility model belongs to the field of measuring technique of bearing rigidity, and what relate generally to is a kind of measurement mechanism of rigidity of special-shape bearing.
Background technology
Rigidity is the ability of component of machine resistance to deformation when being subjected to external force, can determine by the displacement when measuring stress deformation.Bearing industry at home, the bearing radial rigidity is measured also not have relevant measuring method, measurement standard and surveying instrument at present, and the multi-user just carries out Theoretical Calculation to the rigidity of bearing greatly.The actual rigidity value that can accurately reflect bearing to the measurement of bearing radial rigidity, for product processing provides the important parameters index, guarantee product quality, its radial displacement remains in the specialized range when guaranteeing that bearing is subjected to rated load under actual working state.The method of the Theoretical Calculation that adopts usually is subjected to all multifactor influences and restrictions such as bearing parts profile, material, Technology for Heating Processing, machining precision at present, can not accurately obtain the actual rigidity value of bearing, especially for high-precision elastic beam spring bearing, the rigidity project demand is most important, so the special-purpose Rigidity Surveying Instruments of development becomes the important step of dealing with problems.
Summary of the invention
The purpose of this utility model produces thus, a kind of measurement mechanism of rigidity of special-shape bearing is proposed, realize measuring special-shape bearing corresponding displacement under specified load, satisfy displacement measurement errors simultaneously and be no more than 1 μ m, repeatability, stability height, easy to operate, thus satisfy the measurement of the actual radial rigidity of special-shape bearing, improve the quality of bearing products.
For achieving the above object, the technical scheme that the utility model is taked is: it is by base, measure the installing and locating plate, the solid bearing lasso is with socket head cap screw and nut, fixing dial framework, meter, annular lanyard and load structure, measuring the installing and locating plate is vertically fixed on the base, be provided with the mounting hole that is uniformly distributed along the circumference by the upper part at measurement installing and locating plate center, fixedly dial framework is installed on the measurement face of measuring installing and locating plate top, measured bearing is fixed on the mounting hole of measuring on the installing and locating plate by the solid bearing lasso with socket head cap screw and nut, meter is arranged in the mounting hole of fixing dial framework and makes the table point place measured bearing external diameter surface peak place, the annular lanyard is enclosed within on the outer ring outside surface of measured bearing and avoids the table point, and load is suspended on the annular lanyard.
The utility model is a kind of isolated plant at special-shape bearing stiffness measurement under radial load, it is according to product requirement, the mode that adopts the suspension type radial grading to load, at given position, the radial displacement of measurement bearing under the different radial loads, obtain the rigidity value of bearing by formula, therefore this measurement mechanism possesses the measuring accuracy height, repeatability and good stability, hierarchical loading, characteristics such as convenience is accurate. be to satisfy above measurement requirement, the dimensional accuracy of each parts of choose reasonable instrument, form and position tolerance and quality of fit, improve the measuring accuracy of measurement mechanism. because of the measured bearing size little, it is big that institute adds load, measuring accuracy requires high, the size of appropriate design measurement mechanism, important parameter such as intensity and precision, interfere situation between each parts when avoiding measured bearing to measure, be the authenticity of avoiding loading the stressed generation deformation effect of instrument itself measured value when measuring simultaneously, adopt finite element method that measurement mechanism itself is carried out the rigidity verification, optimal design, the final realization effectively, accurately, easily bearing to be measured. this measurement mechanism has solved the measurement difficult problem of special-shape bearing radial rigidity, can obtain the actual rigidity value of bearing parts accurately and conveniently, avoided according to Theoretical Calculation, material, thermal treatment, the influence of various factorss such as machining precision, the rigidity that can reflect bearing parts really, improve the quality of product. the present invention has filled up the technological gap that domestic bearing industry is measured the special-shape bearing radial rigidity, for special-shape bearing particularly the development of elastic beam block bearing technical support is provided.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-base, 2-are measured the installing and locating plate, and 3-solid bearing lasso is with socket head cap screw and nut, and 4-is dial framework fixedly, the 5-meter, and the 6-measured bearing, 7-annular lanyard, 8-loads.
Embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiments of the invention:
Present embodiment is to adopt suspension type load load mode to the stiffness measurement method of special-shape bearing under radial load, radially classification applies different load (Δ P) at bearing outer ring axial restraint length place, and at the loading place measurement corresponding radial displacement of bearing (Δ S), by Rigidity Calculation formula K=Δ P/ Δ S, draw the radial rigidity value of this bearing.
The device that adopts is as shown in Figure 1: by base 1, measure installing and locating plate 2, solid bearing lasso with socket head cap screw and nut 3, fixedly dial framework 4, meter 5, annular lanyard 7 and loading 8 constitutes, measure installing and locating plate 2 by screw retention on base 1, make and measure the boss surface of installing and locating plate 2, on the basis of considering convenient processing and manufacture, guaranteed the precision and the intensity of measurement mechanism perpendicular to base 1 top.Be uniformly distributed with a plurality of mounting holes at measurement installing and locating plate 2 centers along the circumference by the upper part, directly over the mounting hole distribution circle center of circle with two socket head cap screws fixedly dial framework 4 be installed on the measurement face of measuring installing and locating plate 2, fixedly dial framework 4 is provided with mounting hole, measured bearing 6 is fixed on socket head cap screw and nut 3 with the solid bearing lasso by mounting hole and measures on the installing and locating plate 2, and makes its stress equalization.What meter 5 adopted is point table point or the sharp structure of curved table, is installed in the mounting hole of fixing dial framework 4, and the table point places measured bearing 6 external diameter surface peak places, and is returned to zero in meter 5 locking backs.(apart from end face distance H place is installed) packages along specified cross-section place, measured bearing 6 outer ring with annular lanyard 7, and it is sharp to avoid table, load 8 is suspended on the annular lanyard 7, annular lanyard employing multiply nylon rope has increased annular lanyard 7 when guaranteeing tensile strength and measured bearing reads the displacement of measured bearing 6 under corresponding load from meter 5.
During use, measurement mechanism is placed on the flat board or table top of level, hangs load one end and suitably protrude platform, the load 9 of suspension and measurement mechanism and surrounding environment are not interfered.Require steadily to increase successively load 8 according to bearing products, leave standstill a moment after each the loading, treat to read measured value behind the steady load line item of going forward side by side.Take off load after finishing a perfect measurement.To each measured bearing parts measurement three times, and write down each measured value, each tested part is got the mean value of three measured values respectively under same load, as this load displacement of taking place of measured bearing down, by Rigidity Calculation formula K=Δ P/ Δ S, thereby draw the radial rigidity value of this bearing.
