The utility model has taken into full account test process high speed operation, the requirement such as reliable and stable that responds and turn round fast, and the simple compact and reasonable of integral arrangement, easy for installation, test data are stablized the features such as accurate.
Brief description of the drawings
Further illustrate the utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model mechanical connection sectional structure schematic diagram.
In figure: 1-drive motor 2-locked-rotor device 3-torque sensor 4-shaft coupling 5-protective cover 6-intermediate supports seat 7-fixture 8-test specimen 9-base.
Embodiment
Shown in Fig. 1, by drive motor 1, locked-rotor device 2, torque sensor 3, shaft coupling 4, intermediate supports seat 6, fixture 7, base 9 forms, the output shaft of its drive motor 1 packs shaft coupling 4 right-hand member axis holes into, locked-rotor device 2 lower end pins insert shaft coupling 4 right-hand member radial holes, pin bottom props up the output shaft of drive motor 1, torque sensor 3 two ends ring flanges connect respectively the transmission shaft right-hand member ring flange of shaft coupling 4 left end ring flanges and intermediate supports seat 6 with bolt, aforesaid intermediate supports seat 6 left end casings are connected with another bolt with fixture, the transmission shaft left end of intermediate supports seat 6 stretches out casing.
Further, shaft coupling 4 and torque sensor 3 are covered with protective cover 5.
Further, between drive motor 1 mounting hole, torque sensor mounting hole 3, intermediate supports seat 6 mounting holes and base 9, fix with foot bolt.
Further, between the output shaft of drive motor 1 and shaft coupling 4 right-hand member axis holes with key or spline joint.
Further, between the transmission shaft right-hand member of intermediate supports seat 6 and ring flange with key or spline joint.
In Fig. 1, the transmission shaft left end of intermediate supports seat 6 connects test specimen 8 by another shaft coupling.
Adopt little inertia high-speed driving motor 1, tail end installs non-contact code device additional, for tachometric survey and control.Drive motor 1 adopts water-cooled, its efficiency is far above air-cooled, distributing of the amount of heat that be conducive to because of frequent start-stop, heavily loaded running produces for a long time, also avoid bearing and winding temperature rise too high, in addition, water-cooled does not almost have sound, can effectively reduce stand noise, and this meets the test request of the stricter electric powered motor drive motor of noise requirements.Drive motor 1 output shaft arranges locked-rotor device 2, combines together with drive motor 1, shortens axial dimension as far as possible, is beneficial to lifting rotating speed.When locked-rotor device 2 carries out locked rotor test for tested motor, drive motor 1 output shaft is reliably fixing, and then measure stall moment of torsion.Base 9 base plates are reserved pin-and-hole, are convenient to be located after Installation and Debugging.
Due to the frequent frequent start-stop of drive motor 1 or in lasting running at a high speed, so the moment of inertia of rotary device is as far as possible little, anti-overload ability is eager to excel and axial length should be as far as possible little.The utility model has been selected contactless high rotary speed torque sensor 3, can between rotor and stator, carry out the data transmission of extremely safe, under the very large rugged environment of electromagnetic interference (EMI), vibration, humidity or temperature variation, can obtain measurement data reliably and with long-term.Torque sensor 3 is by being connected with intermediate supports seat 6 with drive motor 1 with shaft coupling 4, and it blocked to protection with protective cover 5.Protective cover 5 is made circular arc, and inwall approaches to the distance of revolving part as far as possible, is beneficial to Air Flow, is beneficial to reduction noise, and set up rubber at installed surface, pre-vibration prevention.
The effect of intermediate supports seat 6 is that test specimen 8 and torque sensor 3 are separated, and output terminal is connected with test specimen (tested motor) main shaft through another shaft coupling, and locating flange is accurately located for fixture 7.Bearing is selected high-speed bearing, and the axle coordinating with it and hole are by the design of handbook regulation and processing.3 of torque sensors bear moment of torsion, and other load is all born by intermediate supports seat 6, and torque sensor 3 has obtained effective protection.The transmission shaft of intermediate supports seat 6 is selected superior alloy steel, and configuration design becomes the spindle shape of strength structure, can resist the bending that High Rotation Speed produces, and its critical rotary speed can be calculated by software.The bearing of intermediate supports seat 6 is generally weld assembly or cast member, must carry out abundant crash handling.
