Among the figure, the 1-support, 2-is chuck fixedly, and 3-swings chuck, 4-supporting bearing base, 5-axle, 6-crank, 7-dial, 8-conical gear, 9-motor, 10-associated mode pin pendulum speed reduction unit.
Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following example now, and conjunction with figs. is described in detail as follows:
Embodiment
With reference to accompanying drawing 1 and Fig. 2.
Cable torsion reliability experiment instrument comprises drive motor and support, and drive motor is loaded on the support, and dial 7, crank 6, cable test portion tilting mechanism and fixed mechanism are housed on the top of the shelf.Motor 9 connects driving chuck 7 by associated mode pin pendulum reductor 10, conical gear 8.The shifting block sum counter is housed on the dial 7.Shifting block is stirred crank 6 transmission shafts 5, and the tilting mechanism that axle 5 transmissions link to each other is swung repeatedly.Axle 5 is installed on support 1 by supporting bearing base 4.Fixed mechanism is fixing chuck 2, and tilting mechanism is for swinging chuck 3.Tilting mechanism is corresponding with cable test portion fixed mechanism to be provided with installation.
The course of work of present embodiment:
This test unit is by motor 9, associated mode pin pendulum speed reduction unit 10, and one group of conical gear 8 drives dial 7 rotations, make fixedly shifting block on the dial stir crank and swing repeatedly along stationary shaft, it is that swing is repeatedly done in the center of circle with transmission shaft 5 center lines that the transmission shaft 5 that supports by supporting bearing base 4 makes the swing chuck.Test specimen distributed be clamped on the swing chuck and fixedly between the chuck, test specimen produces moment of torsion with the motion of swing chuck, the situation of reversed torsion that cable is produced thereby the simulation locomotive is in operation reaches the purpose of test.
The stationkeeping of shifting block is on the circumference of distance dial center line 180mm on the dial, and crank center line-spacing shifting block center line minimum length is 55mm, and the pendulum angle that can guarantee crank like this is 100 degree, and meets design requirement.For simulating the ruuning situation of locomotive reality truly, and reach the purpose of test, the swing frequency of crank is defined as 17.5 times/minute, and such frequency is realized by ratio of gear by the pin pendulum-type speed reduction unit of motor direct connection.
Violent vibration in the locomotive that this test is run at high speed by simulation, wave, 6mm 2-240mm 2Locomotive cable test portion carries out the reversed torsion reliability and detects.Side at dial is equipped with near switch, once reverses power whenever dial rotates promptly to finish in a week, and counter is promptly counted once, can be according to testing requirements, set the detection cycle index arbitrarily by electronic counter, reach automatic stopping behind the set point number, and write down test number (TN) automatically.
