The bottom of described table top is connected into frame-shaped construction with steel welding, guarantees that the distortion of its intensity generation when loading is less than 2mm.
The present invention compares with existing torque calibrating device, and following advantage and beneficial effect are arranged:
1. the present invention has designed the brand-new load mode of a cover, and utilization has the wire rope of certain flexibility as the medium of power transmission, and loading force and reacting force thereof are all acted on the table top.The whole suffered external force of torque calibrating device is that the pressure that bear on ground only be the deadweight of caliberating device self, and for example the torque calibrating device generation of 100KNm range is to the pressure on ground about 8KN only, half of too late existing 5000KNm moment of torsion demarcation machine.Therefore the present invention does not need generally to demarcate the necessary heavy fuselage of machine and complicated ground engineering, can greatly save manufacturing, installation and transportation cost.
2. when loading because the gap of bolt and stressed after distortion, low-angle rotation can occur in loading beam, the loading end of loading beam of the present invention adopts designed arc-shaped appearance, and select the wire rope that has simultaneously flexibility and rigidity as the device of the power of transmission, can effectively avoid the error that rotational deformation produces when loading, guarantee the accuracy of standard torque that tested sensor is applied.
