Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing 1-3.
With reference to Fig. 1, testing table is driven by drive motor 9, drive motor 9 general with headstock 8 in less spool being connected of moment, therefore passing spools 2 of casing 13 in drive motor 9 and the headstock 8 is connected, the other end of axle 2 passes casing 13 and is connected with torque and speed sensors 6, two output terminals of loader 10, one with headstock 8 in axle 14 be connected, one is connected with gear 15 in the headstock 8, the other end of axle 14 connects torque arm 11 and transmission shaft 12, and be connected with gear 15 in the fully sheathed case 1, tubular shaft 2 in the fully sheathed case 1 passes casing 13 and is connected with torque and speed sensors 3 by being through wherein transmission shaft, with two identical tested speed reduction units 4 and 5, perhaps tested speed reduction unit 4 and one and the on all four gearing 5 of tested speed reduction unit 4 ratio of gear, be connected in headstock 8, between fully sheathed case 1 and torque and speed sensors 3 and 6, thereby formed closed-loop, torque arm 11 is in order to assist the twisting vibration of loader 10 smooth loadings and absorption system.Drive motor 9 makes the loading moment work done in order to the rotation of drive system, and the energy loss of replenishment system.
With reference to Fig. 2, loading moment in the headstock 8 is by gear 15 warps and its meshed gears 21, axle 20, gear 22, reach gear 18 with gear 22 meshed gears 19, tape spool, and and gear 18 meshed gears 16, and with gear 16 meshed gears 17 after, loading moment amplifies step by step, and the moment maximum of axle on 7, moment on the axle 2 is taken second place, and also can the moment on the axle 2 be designed to maximum according to the needs of test.Enlargement factor is different and different to the ratio of gear of gear 16, gear 17 with gear 15.For example: if the ratio of gear between gear 15 and the gear 16 is 3.6, and the ratio of gear between the gear 17 is 2.2 o'clock, and then when the loading moment of loader 10 is 15000N.m, the test moment on spools 7 is 50000N.m, and the experiment moment on spools 2 is 30000N.m.When the test speed of axle 7 was 1000r.p.m, test power was 5233KW, and when the test speed of axle 2 was 1500r.p.m, test power was 4710KW.
