Description
Technical field
The utility model belongs to aero-engine wheel disc experimental technique, is specifically related to the reliable syndeton of a kind of wheel disc trial position.
Background technology
When rotation test done by aero-engine wheel disc, design exchanging structure is needed to connect wheel disc and testing equipment, to load rotary speed.
The exchanging structure of existing wheel disc rotation test comprises Coupling Shaft and axle journal.Wherein, between Coupling Shaft with axle journal, adopt screw to be connected, and have radial seam to coordinate location; The other end connection device of Coupling Shaft; The other end joint test wheel disc of axle journal.This structure can realize the connection function of testpieces and testing equipment, to carry out rotation test.
But existing exchanging structure, in rotation test, after loading rotating speed and temperature, the centrifugal load of wheel disc and axle journal is excessive, and the radial fit seam between Coupling Shaft and axle journal easily occurs gap, and it is unreliable to locate in process of the test, can vibrate excessive equivalent risk.
Utility model content
The utility model object is: provide a kind of and connect reliable, structure simple wheel disc trial position syndeton.
The technical solution of the utility model is: a kind of wheel disc trial position syndeton, and it comprises Coupling Shaft, axle journal, group section, and wherein, group section is L shape structure, and its longitudinal end and Coupling Shaft are fixed, and axial end is fixed by a boss and axle journal.
Fixed by screw between Coupling Shaft and group section, fixed by pin between axle journal and group section.
Axle journal junction is positioned at below group section, and pin up runs through group section from axle journal.
Group section axial end thickness is less than its longitudinal end thickness.
The axial dimension of group section axial end is 2 to 4 times of longitudinal end thickness.
Technique effect of the present utility model is: the utility model wheel disc trial position syndeton can realize Coupling Shaft by increase group section and be connected with the effective of axle journal, ensure that the location of rotating disc is reliable, posting is reliable, intensity is reliable.After applying this structure, the rotary speed of spin test facility accurately can be passed to test wheel disc, the stress state of accurate reproduction test wheel disc when engine operation.

Fig. 1 is the reliable syndeton schematic diagram of a kind of wheel disc trial position;
Fig. 2 is the partial enlarged drawing of Fig. 1,
Wherein, 1-Coupling Shaft, 2-group section, 3-axle journal, 4-screw, 5-pin;
A-group section longitudinal end, B-group section axial end, C-boss.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further:
Refer to Fig. 1, the utility model wheel disc trial position syndeton comprises Coupling Shaft 1, axle journal 3, group section 2.Wherein, group section 2 is L shape structure, and its longitudinal end A and Coupling Shaft 1 are fixed, and axial end B is fixed by a boss C and axle journal 3, to shorten assembling length.And fixed by screw 4 between Coupling Shaft 1 and group section 2, fixed by pin 5 between axle journal 3 and group section 2, be connected with the effective of axle journal 3 to realize Coupling Shaft 1.
Refer to Fig. 2, described axle journal 3 junction is positioned at below group section 2, and pin up runs through group section 2 from axle journal 3, locates and torsion pass function to realize pin 5.During test, the centrifugal force of pin 5 makes it be close to axle journal 3, to realize self poisoning; Pin 5 can bear the shearing that moment of torsion in testpieces acceleration and deceleration process and inertia produce.
Described group section 2 axial end B thickness is less than its longitudinal end A thickness, and the axial dimension of group section 2 axial end B is 2 to 4 times of longitudinal end A thickness, to adjust axis and the radial rigidity of group section 2.Utilize the centrifugal load of axle journal 3 and test wheel disc, make group section 2 produce axial bending moment, thus control the radial deformation of group section 2 longitudinal end A, ensure the location of Coupling Shaft 1 and the radial seam of group section 2.
The utility model wheel disc trial position syndeton can realize Coupling Shaft by increase group section and be connected with the effective of axle journal, ensure that the location of rotating disc is reliable, posting is reliable, intensity is reliable.After applying this structure, the rotary speed of spin test facility accurately can be passed to test wheel disc, the stress state of accurate reproduction test wheel disc when engine operation.
