Support one end is mounting flange face, and internal stent is provided with the base of two bearing seats; The inside surface of load end sleeve flange and transition disc end sleeve flange is provided with keyway, is connected by flat key with the shaft type torque sensor installed additional; The outside surface of that section of load end sleeve flange between shaft type torque sensor and bearing is provided with screw thread, is threaded with two round nut; The outside surface of symmetrical that section of transition disc end sleeve flange between shaft type torque sensor and bearing is provided with screw thread, is threaded with two round nut; Sleeve and sleeve are enclosed within transition disc end sleeve flange, load end sleeve flange respectively; Shaft end ring and shaft type torque sensor are fixed by screw; Bearing and bearing are enclosed within transition disc end sleeve flange, load end sleeve flange respectively, and coordinate with it.
When not adding installing shaft type torque sensor, the torque that motor exports is measured by existing flange form torque sensor.After adding installing shaft type torque sensor, the torque that motor exports first is obtained the numerical value of low precision by the measurement of existing flange form torque sensor, obtain high-precision numerical value by the shaft type torque sensor measurement installed additional through transition disc, transition disc end sleeve flange, then output to load through load end sleeve flange again.
Effect of the present invention is as follows:
The present invention adopts said structure, because support and motor are connected, the shaft type torque sensor installed additional passes through bearing block support, and then provide multiple tie point by the Flange joint of support and motor, improve the rigidity adding assembling structure, structure stability in operational process improves, and when turning round at a high speed, the amplitude of vibration obviously reduces, and uses reliable; Upper encloser and a housing be configured to shield jointly, prevent structure member from throwing away injury workman when high-speed rotation breaks down, protection safety of workers; Because shaft type torque sensor can be moved from transition disc end sleeve flange side to load end sleeve flange side between transition disc end sleeve flange and load end sleeve flange, compare the installation method of fixing shaft type torque sensor, can avoid producing larger additional bending moment cause the operating mode of heating at high-speed cruising under, it is accurate to realize the measurement of moment of torsion; Whole installation, the convenient disassembly adding assembling structure, avoids the mounting or dismounting to existing flange form torque sensor, not only increases efficiency, and avoids because the reduction of the installation accuracy of existing flange form torque sensor that causes of thread abrasion.
