Description
Technical field:
The utility model relates to a kind of reverse torsion machine, particularly relates to a kind of hydraulic pressure inertia reverse torsion machine, is used for the mechanical test of test material and member.
Background technology:
Present reverse torsion machine both domestic and external mainly contains following several form: the hydraulic servo reverse torsion machine, be to drive to reverse with high pressure fuel source to do the reverse loading of device realization to sample, to the various variablees in the test, all can control as moment of torsion, corner, frequency etc., the simulation of test is very good, but its equipment price height, water power consumes excessive during test.Mechanical type inertia reverse torsion machine is that the rotatory inertia quality with driven by motor loads sample, and the frequency of ordinary test is nonadjustable, and this testing machine preload is difficulty relatively, normally carries out prestrain with spring or air bag.Electromagnetic exciting formula reverse torsion machine, be with a test specimen and an inertia torsional vibration system perfect rigidity connect together, make system's torsional resonance with an electro-magnetic exciting force, thereby realize loading to sample, this equipment test consumption is few, but test frequency is non-adjustable, and the sample assembling is difficulty relatively.
Summary of the invention:
The purpose of this utility model is to provide a kind of hydraulic torsional fatigue tester, and it is rational in infrastructure, has improved the prestrain ability of mechanical type inertia fatigue tester, and its cost is low, easily operation.
The technical solution of the utility model is achieved in that hydraulic pressure inertia reverse torsion machine, is done device, oil sources, angular transducer, machinery inertial load maintainer etc. and is formed by control system, torque sensor, hydraulic pressure pwc loading; Wherein hydraulic pressure pwc loads and to make device by rotor, fixedly housing and catch are formed; Two catch are fixedly being arranged between housing and the rotor, and one is fixed on fixedly on the housing, and one is fixed on the rotor.The machinery inertial load maintainer is fixed on the hydraulic pressure pwc loading and does device rotor one end, is made of gear drive and eccentric wheel.
Good effect of the present utility model is that it is rational in infrastructure, has improved the prestrain ability of mechanical type inertia reverse torsion machine, and its cost is low, easily operation.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A-A sectional view of the present utility model.
Fig. 3 is a B-B sectional view of the present utility model.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing, as shown in Figure 1, 2, 3: hydraulic pressure inertia reverse torsion machine, by control system, grapple sensor, hydraulic pressure pwc and load and do compositions such as device 1, oil sources, angular transducer, machinery inertial load maintainer 2; During test sample being fixed on the loading of torque sensor and hydraulic pressure pwc does between the device 1, control the direction and the size of sample preload by the flow direction of regulating oil supply pressure and oil, the size of load can show from switch board through torque sensor, and the size of torsion angle also can show on switch board by angular transducer; Dynamic loading is rotated by the driven by motor inertia rotors and is added, motor speed is high more, it is big more that institute adds dynamic loading, and switch board can be controlled rotating speed of motor, and the pivot angle the when size of dynamic loading and loading can show on switch board through torque sensor and angular transducer; The work of inertia loading system is by rotor 3, fixing housing 4 and rotor 3 catch 5 are formed, two catch 5 are fixedly being arranged between housing 4 and the rotor 3, one is fixed on fixedly on the housing 4, one is fixed on the rotor 3, regulates preloading size by the adjusting oil pressure.
