Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.
Participate in Fig. 1～Fig. 3, a kind of gearing for electromechanical testing, comprise columniform transmission tube 1, be placed in the tube core rotor 2 in transmission tube 1, transmission tube 1 and winding article (not shown), be connected as one end of roller shutter etc., tube core rotor 2 can, for being connected with the output shaft of motor, when tube core rotor 2 drives rotation by motor, can drive transmission tube 1 to rotate, thereby the lifting of drive roller shutter etc., to carry out the test of motor performance.
Transmission tube 1 offers the columniform accommodating cavity 11 that axially extended two ends are all in communication with the outside, and tube core rotor 2 is placed in this accommodating cavity 11.On the first end perisporium of transmission tube 1, offer the groove 12 being communicated with accommodating cavity 11, in groove 12, there is stage portion 13.Groove 12 is interior for fixture block 14 is set, fixture block 14 has flange 141, can coordinate with stage portion 13, fixture block 14 parts that are positioned at flange 141 1 sides extend into accommodating cavity 11 through groove 12, define in one direction thus the position of fixture block 14, when flange 141 and stage portion 13 butt, fixture block 14 just can not be further to the interior insertion of accommodating cavity 11.Being positioned at butt on flange 141 opposite sides has one end of the first spring 15, reference column 142, the first springs 15 can be set in this side of flange 141 and be arranged on reference column 142 peripheries, makes the first spring 15 can not do moving radially relative to fixture block 14.
Be arranged with laterally the other end of collar 3, the first springs 15 and the inner side butt of collar 3 the first end week of transmission tube 1, thus, define the distance that fixture block 14 moves to collar 3, when fixture block 14 moves to collar 3, the first spring 15 is compressed.Can be fixing by the first bolt 31 between collar 3 and transmission tube 1.
On the perisporium of tube core rotor 2, offer axially extended groove 21, fixture block 14 extends into accommodating cavity 11 and can be inserted into after interior in groove 21 and coordinate with groove 21.The madial wall of transmission tube 1 is provided with projection 16, projection 16 is inserted in groove 21 too, thereby realize fixing at the relative position that makes progress in week between transmission tube 1 and tube core rotor 2, make thus transmission tube 1 and tube core rotor 2 synchronously to rotate, preferably, projection 16 can lay respectively at groove 12 two ends of transmission tube 1.Appropriate section on tube core rotor 2 periphery walls between groove 12 and projection 16 is also arranged with the second spring 22, on tube core rotor 2 periphery walls, as the position of contiguous groove 12 has the first radially outward outstanding teat 25, and on transmission tube 1 internal perisporium, as the position of adjacent protrusions 16 has the second teat 18 of radially inwardly giving prominence to, during original state, one end of the second spring 22 and the first teat 25 butts, and the other end is in free state, the second spring 22 does not stress.The part that tube core rotor 2 extends to the second end outside of transmission tube 1 is provided with back-up ring 23, and the external diameter of back-up ring 23 is greater than the diameter of accommodating cavity 11, makes tube core rotor 2 can not do the axially-movable towards the first end of transmission tube 1.
In tube core rotor 2, offer can power supply machine output shaft insert fixing mounting hole 24, in the present embodiment, mounting hole 24 is square.Transmission tube 1 can be fixing by the second bolt 17 on perisporium with outside winding article.According to the difference of motor to be tested, this gearing is also connected with the output shaft of motor by different connected modes.
Referring to Fig. 4 and Fig. 5, the first output shaft 41 of the first motor 4 is square with mounting hole 24 adaptations, the first output shaft 41 directly can be inserted in mounting hole 24, the installation that can complete the first motor 4 and tube core rotor 2 is fixed, thus, the first motor 4 rotates and can drive tube core rotor 2 to rotate, thereby carries out next step motor performance test after driving transmission tube 1 to rotate.
Referring to Fig. 6 and Fig. 7, the second output shaft 41 ' of the second motor 4 ' is the circle that diameter is larger, adaptive with the internal diameter of accommodating cavity 11, offers the draw-in groove 411 ' coordinating with fixture block 14 on the periphery wall of the second output shaft 41 '.During use, the second output shaft 41 ' is inserted in accommodating cavity 11, promoting tube core rotor 2 moves towards the second end of transmission tube 1, fixture block 14 is radially outward promoted, compress the first spring 15, and a part for tube core rotor 2 is ejected from the second end of transmission tube 1, until can make draw-in groove 411 ' aim at fixture block 14 after rotating the second output shaft 41 ', fixture block 14 is under the restoring force effect of the first spring 15, can be inserted into automatically in the draw-in groove 411 ' of the second output shaft 41 ', now the two ends of the second spring 22 respectively with the first teat 25 and the second teat 18 butts, tube core rotor 2 can not be further moves to the second end of transmission tube 1, the installation that completes thus motor 4 ' and tube core rotor 2 is fixed, this process operation is very convenient.For ease of the second output shaft 41 ', in the interior insertion of accommodating cavity 11 and extraction, preferred, its both sides of fixture block 14 parts that are positioned at flange 141 1 sides are curved.
Because the output shaft rotating speed when motor is when very fast, fixture block 14 likely can not coordinate with draw-in groove 411 ' and cannot realize transmission agency, and to be therefore applicable to rotating speed slower for gearing of the present invention, and moment is from zero to the tube shaped electric machine increasing progressively successively greatly etc.
