Embodiment
Below in conjunction with specific embodiment, the present invention is described:
Rotor of motor having no brush overspeed test special purpose device in the present invention, is made up of the source of doing, support section and connecting shaft part.When testing, rotor to be measured is firmly secured on support section, by connecting shaft part with do source part and be connected, driving rotor to operate under rated speed certain hour by doing source part, completing motor rotor overspeed test.
Rotor overspeed test unit structural representation is shown in accompanying drawing 1, and the source of doing is made up of direct-flow voltage regulation source 1, prime mover 2, and D.C. regulated power supply provides operating voltage for prime mover, provides power source by prime mover for rotor to be measured, drags rotor to be measured running.
Support section is made up of prime mover supporting and location seat 3, base plate 4, rotor supports location-plate, and prime mover supporting seat 3 is used for fixing prime mover, and rotor supports location-plate 5,6 is used for bearing and fixes rotor to be measured.The Y of prime mover is determined by the design shape of prime mover supporting seat 3 and size, the volume coordinate of Z-direction, by rotor supports location-plate 5, the design size of 6 determines rotor Y to be measured, the volume coordinate of Z-direction, finally with the screw matched by prime mover supporting seat 3 and rotor supports location-plate 5, 6 are fixed on base plate 4, by the position of base plate 4 upper screwed hole ensure the axis of prime mover and rotor to be measured X to coordinate position consistent, by prime mover supporting seat 3 and rotor supports location-plate 5, the axis Y of 6 guarantee prime mover and rotor to be measured, Z-direction coordinate position is consistent, ensure that prime mover is connected with the coaxial of rotor to be measured.Prime mover supporting seat 3, base plate 4 and rotor supports location-plate 5,6 machines by aluminum alloy materials, not only alleviate the overall weight of device, be convenient to carrying carry, in turn ensure that the rotor to be measured of band magnetic does not adsorb with device and causes rotor damage or damage to operating personnel.
Connecting shaft part is realized by the shaft joint 7 that is flexible coupling.By the design of rotor supports riser to be measured, prime mover supporting seat and base plate, the right alignment of basic guarantee between rotor to be measured and prime mover, bring the hidden danger of mechanical damage in order to eliminate disalignment further to rotor to be measured, in this scheme, shaft joint is designed to the form that is flexible coupling.The shaft joint that is flexible coupling is divided into and rotor coaxial coupling part to be measured and coupling part coaxial with prime mover, the wherein center pit of coaxial coupling part and original machine output shaft secure fit with prime mover, be step through-hole with the center pit of rotor coaxial coupling part to be measured, step through-hole one section and rotor secure fit to be measured, one section coordinates with original machine output shaft, to distribute four through holes with the coaxial coupling part of prime mover with rotor coaxial coupling part to be measured correspondence position, with being flexible coupling, rope connects the two portions together, by the regulating action of the rope that is flexible coupling, eliminate the impact that rotor to be measured and prime mover rotating shaft disalignment are brought.
When using this device to carry out overspeed test to rotor, first rotor to be measured is installed on test unit.During installation, prime mover 2 is fixed on after on prime mover supporting seat 3, again prime mover supporting seat 3 is reliably fixed on base plate 4, then rotor supports location-plate 6 is screwed on base plate 4, bearing rotor start to be measured being exported one end loads in the bearing chamber of rotor supports location-plate 6, rotor to be measured and prime mover is connected respectively with the two parts of the shaft joint that is flexible coupling, subsequently rotor other end bearing to be measured is loaded in the bearing chamber of rotor supports location-plate 5, rotor supports location-plate 5 is fixed on base plate 4, check that each parts connect firm, non-loosening.
After rotor to be measured is reliably connected with prime mover 2, by the lead-in wire of prime mover 2 access direct-flow voltage regulation source 1, the output voltage of slow rising direct-flow voltage regulation source 1, prime mover 2 is driven steadily to accelerate to rotate, and drive rotor to be measured steadily to accelerate to rotate, voltage is increased to rotor speed to be measured when reaching the rotating speed that overspeed test condition specifies, keep direct-flow voltage regulation source 1 output voltage constant, , allow after rotor smooth operation overspeed test condition official hour to be measured under regulation rotating speed, slow reduction voltage, until D.C. regulated power supply output voltage is reduced to zero, prime mover and rotor to be measured shut down, complete rotor overspeed test.
When changing rotor to be measured, only need the screw of fixed rotor support positioning plates 5 to unclamp, unclamp the screw of fixed rotor part on the shaft joint 7 that is flexible coupling simultaneously, the rotor completing overspeed test can be extracted from rotor supports location-plate 6.Single unit system is convenient to use, safe and reliable, time saving and energy saving, has saved human cost, has improve work efficiency.
