Abstract
The invention relates to a pure torque loading device which applies force via single point, belonging to the technical field of torque loading devices, for resolving the torque generation problem of torque loading devices. The pure torque loading device which applies force via single point comprises a force arm rod and a support provided with a transition balance rod, wherein two ends of the force arm rod are respectively provided with a screw rod, one end of the screw is connected with an afterburning nut while the other end is connected with the transition balance rod. The pure torque loading device adopts a transition balance rod and a transition bearing, to effectively convert the moment generated on a tested object in the afterburning process of the nut into a reaction force at the other side of the force arm rod, thereby eliminating moment and calibrating the pure torque of the tested object, while the calibrated value can be real-timely observed by a corresponding collection system. The in-situ static calibration reaches 30000 Newton meters, the torque increase and torque decrease has good calibration repeatability, and the maximum linear error is lower than 0.2%.
Description
Technical field
The invention belongs to moment of torsion charger technical field, specifically a kind of single-point applies the pure torsion charger of power.
Background technology
For working stability after guaranteeing system's entrucking reliable, each subsystem in the loading spectrum test must be carried out moment of torsion and be demarcated, the torsion-testing data are of paramount importance test figures in the loading spectrum test, and its precision need be protected, so must demarcate accurately testing element.At present, be applicable to the static demarcating of moment of torsion of the survey torque sensor of axle, utilize " power and arm of force principles " apply power at the two ends of the fixing arm of force simultaneously, the generation moment of torsion.This method is demarcated for the high little moment of torsion of precision prescribed and is existed arm of force two ends to be difficult for loading simultaneously, and the in a single day stressed difference in two ends is inevitable to produce the additional force problem at the centre of gyration, is difficult to satisfy accurate little moment of torsion calibration request.
Summary of the invention
The object of the present invention is to provide a kind of pure torsion charger that can accurately reflect the system testing stability, be fit to power that the single-point of demarcating of axle is applied.
Realize the technical scheme of the object of the invention: a kind of single-point applies the pure torsion charger of power, comprises arm bar, and support is provided with the transient equilibrium bar; The arm bar two ends are respectively equipped with screw rod, and an end of screw rod is connected with afterburning nut, the other end is connected with the transient equilibrium bar.
The mounting hole of described arm bar is provided with jig.
Effect of the present invention: (1) will be rack-mount by test specimen, arm bar is installed in by on the test specimen, on the torsional moment that applies on the afterburning nut is applied to by test specimen by arm bar and support, this device adopts transient equilibrium bar and transition bearing, with the moment of flexure that the nut afterburner process generates on by test specimen, be effectively converted into the reacting force of arm bar opposite side, finally generate the power of bilateral by one-sided power, eliminated moment of flexure, realized being demarcated by the pure torsion of test specimen.(2) arm bar is provided with anchor clamps, can change according to the size of shaft diameter, can realize the demarcation to various axle moments of torsion respectively.On-the-spot static demarcating is to 30000 Ns of rice, moment of torsion increase progressively with moment of torsion successively decrease and demarcate repeated very good, the maximum linear error is less than 0.2%.
