Description
Technical field: the utility model torque-measuring apparatus structure.
Background technology: torque-measuring apparatus is applied to examine in the measurement mechanism of three grades of hydrodynamic mechanical seals of main pump, is one of important device that detects in real time in three grades of hydrodynamic mechanically-sealing apparatus of nuclear main pump moment of torsion.Three grades of hydrodynamics of nuclear main pump machinery is close to be the important component part of core the most in the nuclear main pump, and can direct relation nuclear main pump safety in nuclear power station, reliability service.If sealing is leaked, will directly cause the reactor shutdown, bring huge economic loss to nuclear power station, also can cause environmental radiation to pollute when serious.
Summary of the invention: the purpose of this utility model provides vertical test units such as mechanical seal, water pump model etc. with respect to the torque-measuring apparatus of slewing, with the shaft power parameter of the equipment under tests such as test sealing or water pump hydraulic model.The test unit that is particularly useful for frequent fast assembling-disassembling.The technical solution of the utility model is: a kind of torque-measuring apparatus, measurement mechanism is vertical, by bearing (1), flange seat (2), deep groove ball bearing (4), thrust deep groove ball bearing (3), the first circlip (5), the second circlip (6), stop screw (7), pilot sleeve (8), first arm of force (9), load-sensing unit (10), articulated joint (11), connecting rod (12) and second arm of force (13) form, bearing (1) and flange seat (2) are all with the step that radial and axial rolling bearing is installed, deep groove ball bearing (4) is positioned at bearing (1), between the boss of flange seat (2), by the first circlip (5) and the second circlip (6) compensation bearing assemblage gap, thrust deep groove ball bearing (3) is positioned at deep groove ball bearing (4) outside, two stop screws (7) symmetry with pilot sleeve (8) is installed on the threaded hole of flange seat (2), and by the gathering sill restriction flange seat (2) of the upper processing of bearing (1) and the rotational travel between the motor support (1), first arm of force (9) is installed on the bearing (1), second arm of force (13) is installed on the flange seat (2), first arm of force (9) upper cantilever end is equipped with load-sensing unit (10), load-sensing unit (10) is linked to each other with second arm of force (13) with articulated joint (11) by connecting rod (12).
Principle of work of the present utility model is:
Torque-measuring apparatus, bearing (1) is rigidly connected with the test-bed fixed part, the effect of playing the support drive component weight and bearing moment of torsion, inside can hold motor shaft end and shaft coupling, and flange seat (2) can be rigidly connected with motor flange.By radially deep groove ball bearing (4) and thrust deep groove ball bearing (3) assembly, realize that the centering of flange seat (2) and bearing (1) also forms circumferential degree of freedom, and can bear larger axial load.Be processed with spacing gathering sill in bearing (1) outer rim, the stop screw (7) and the pilot sleeve (8) that are fixed on the flange seat (2) by screw thread are nested in the spacing gathering sill, play the effect that prevents load-sensing unit (10) and connecting portion overload thereof, and can prevent owing to shaking axial vibration between the link that causes.Be separately installed with first arm of force (9) and second arm of force (13) on bearing (1) and the flange seat (2), two arm of force ends are connected 12 by load-sensing unit (10) with connecting rod) etc. connection, the moment of torsion that the motor rotation produces passes to load-sensing unit (10) and forms the tensile force signal that can be gathered by first arm of force (9) and second arm of force (13), can obtain moment of torsion and the shaft power of rotor by analyzing and processing.
The measurement of the moment of torsion in the measurement mechanism of three grades of hydrodynamic mechanical seals of nuclear main pump that the utility model designs for the operating condition of simulating three grades of hydrodynamic mechanical seals of Nuclear Power Station main pump fully.The measurement mechanism of three grades of hydrodynamic mechanical seals of vertical nuclear main pump and the vertical connection of motor, the utility model is little with respect to traditional torque gauge axial dimension, stability to test unit has higher guarantee, and this technology can be applied to other mechanical torques and measure occasion.
Technological merit of the present utility model is:
1. common torque gauge and dynamometer machine most needs is rigidly connected with ground or frame fixed part separately, need to carry out independent shaft extension design to dynamometer machine or torque gauge when design experiment device rotor, and volume is larger, is not easy to installation.The utility model takes full advantage of the bearing space, and whole height is no more than 120mm, and structure is compacter, and end play increases to 0mm between motor and the tested device.
2. radially deep groove ball bearing and axial thrust deep groove ball bearing assembly by the machining tolerance of control with the bearing fit face, can guarantee the alignment degree of structure fast in installation process, and formation is circumferential degree of freedom and have larger axial carrying capacity accurately.
3. this torque-measuring apparatus is particularly useful for need to repeating to test the occasion of dismounting.
4. measuring the arm of force adopts square steel to be welded, supporting construction has larger rigidity, directly adopt high precision standard LOAD CELLS (precision 0.25%) to measure the normal tension of the arm of force as load-sensing unit, the complex process that need not traditional stickup foil gauge and use LOAD CELLS etc. to demarcate.
