The fatigue test device is characterized in that the slender thin wall shaft is placed on the upper supporting plate and the lower supporting plate and connected by an upper connector and a lower connector; the upper end of the slender thin wall shaft is connected with a sleeve tooth, and a torque stop disc is arranged at the lower end of the slender thin wall shaft; the sleeve tooth is connected with a torque loading disc; and the torque loading disc is connected with a transverse force loading disc and an axial force loading disc. The fatigue test device has a simple structure, is convenient for operation, applies rotating-shearing force and rotational bending moment to the slender thin wall shaft, finishes the fatigue test of the slender thin wall shaft at one time and has the advantages of short test time, high loading accuracy, small test error and good stability and safety.
Description
Technical field
The utility model relates to a class strength test device, is specifically related to a kind of elongated thin wall shaft fatigue experimental device.
Background technology
The destruction overwhelming majority of the elongated thin wall shaft of aeromotor belongs to fatigue break, and alterante stress is the root that causes elongated thin wall shaft fatigue crack to form and expand.Because it is a lot of to influence the factor of intensity and stress, therefore the definite of the degree of confidence of elongated thin wall shaft and fiduciary level technical life must be based on the verification experimental verification under the theoretical direction.Elongated thin wall shaft need bear the compound action of multiple load such as rotation moment of flexure, rotary shear, operation torque, vibration moment of torsion, axial force in real work.In order to realize that elongated thin wall shaft is carried out the fatigue strength examination, the most frequently used is the mechanical rotation charger, applies rotation load by rotating mechanisms such as motor, oil motors, and loading accuracy is difficult to monitoring, test error is big, applies rotary shear or rotation moment of flexure poor accuracy; Another kind adds that to plant device be the standard cycle load of forming by moment of torsion, axial force and vibration moment of torsion, with constant moment of torsion, axial force and rotation moment of flexure same tested axle is carried out the moment of flexure examination again, though can realize rotary shear or rotation preferably plants adding of moment of flexure, but adding, this plants device because test is carried out in two stages, testpieces need vibrate high all load tests of moment of torsion and rotation moment of flexure respectively, and the test period is longer, the testing equipment complexity, operating difficulties, cumulative errors are big.Above-mentioned two kinds add and plant device and all can not meet the demands for elongated thin wall shaft torture test.
Summary of the invention
The purpose of this utility model provides a kind of loading accuracy height, test error is little, the cycle is short, and is simple in structure, easy to operate elongated thin wall shaft fatigue experimental device.
The utility model comprises the loading frame of being made up of crossbeam, triangle support plate, upper and lower back up pad, and elongated thin wall shaft is characterized in that: described elongated thin wall shaft places on the upper and lower back up pad, is connected by upper and lower connector; Be connected with the cover tooth in the upper end of elongated thin wall shaft, the lower end is provided with only turns round dish; Be connected with the moment of torsion loading disc on the described cover tooth; The described dish of only turning round is connected with transverse force loading disc and axial force loading disc.
In order to realize this purpose better, described moment of torsion loading disc, transverse force loading disc and axial force loading disc are connected with hydraulic servo oil cylinder separately.
The utility model is simple in structure, and is easy to operate, simultaneously applies rotary shear and rotation moment of flexure to elongated thin wall shaft, disposablely finishes elongated thin wall shaft torture test, and test period is short, the loading accuracy height, and test error is little, and the stability of test unit and security are good.
