The utility model discloses a double-loop rotating bearing tester shafting structure, which comprises two shafting which can separately rotate, namely an external circle shafting and an internal circle shafting, the structure of the external circle shafting is a suspension arm beam form, and the structure of the internal circle shafting structure is a simple beam form, the suspension arm point of the external circle shafting and the supporting point of the internal circle shafting are the outer ring and the inner ring of a testing bearing (6), the external circle shafting is driven and controlled by a driving motor (1), and the internal circle shafting is driven and controlled by a driven motor (11). The double-loop rotating bearing tester shafting structure can achieve the bearing performance simulation test when the internal and the external loops are simultaneously rotating.

Description

Two lasso swivel bearing testing machine shafting structures

Technical field:

The utility model relates to the bearing test equipment technical field, especially a kind of pair of lasso swivel bearing testing machine shafting structure.

Background technology:

Existing common rolling bearing is single lasso rotation, and it is in the majority with the inner ring rotation, on testing machine, can realize the rotation of bearing and the simulation test of the form of loading more easily, and the bearing (as aeromotor intermediary bearing) that rotates simultaneously for some inside and outside lasso, how truly its working condition of simulation test is a unsolved always problem.

The utility model content:

The purpose of this utility model provides a kind of pair of lasso swivel bearing testing machine shafting structure, can realize the bearing performance simulation test that inside and outside lasso rotates simultaneously.

The technical solution of the utility model is: described a kind of pair of lasso swivel bearing testing machine shafting structure, this shafting structure comprise the axle system of two independent rotations, i.e. outer ring axle system and inner ring axle system; The outer ring shafting structure is the semi-girder form, and the inner ring shafting structure is the free beam form; The cantilever point of outer ring axle system and the fulcrum of inner ring axle system are the outer ring and the inner ring of test bearing; Outer ring axle system and inner ring axle system are driven and control by drive motor respectively.

Described outer ring shafting structure is connected by the outer ring axle of shaft coupling with outer ring axle system by drive motor, the two ends of outer ring axle are respectively charged into the inner ring of two bearings, the outer ring of two bearings is separately fixed on the pedestal of testing machine, and the other end inwall of outer ring axle is connected with the outer ring of test bearing.

Described inner ring shafting structure is connected by inner ring axle one end of shaft coupling with inner ring axle system by another drive motor, and the two ends of inner ring axle are respectively charged into the inner ring of bearing and load bearings, and the outer ring of bearing is fixed on the pedestal of testing machine; The outer ring of load bearings and radial loaded device are hinged, and the other end of inner ring axle is packed in the inner ring of test bearing.

The utility model is obtained following effect: adopted biaxial rotated technical scheme on one-piece construction, it is the independent respectively rotation of outer ring axle and inner ring axle, bearing outer ring is installed on the axle of outer ring and with the outer ring axle and rotates, bearing inner race is fixed on the inner ring axle axle and with the inner ring axle and rotates, two main shafts are controlled respectively, two fully independently axle systems have been formed, fundamentally realized the structural test simulation of two lasso swivel bearings, can carry out the performance simulation test according to its velocity spectrum, loading spectrum test bearing.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Embodiment:

As shown in fig. 1, the utility model is made up of the axle system of two independent rotations, i.e. outer ring axle system (seeing the double dot dash line frame) and inner ring axle system (seeing frame of broken lines).

The outer ring shafting structure is the semi-girder form.

Outer ring axle system is driven and control by drive motor 1, and axle system in outer ring comprises bearing 3, bearing 5, outer ring axle 4 and test bearing 6; Drive motor 1 is connected with outer ring axle 4 by shaft coupling 2, and the two ends of outer ring axle 4 are respectively charged into the inner ring of bearing 3 and bearing 5, and the outer ring of bearing 3 and bearing 5 is separately fixed on the pedestal of testing machine, and the other end inwall of outer ring axle 4 is connected with the outer ring of test bearing 6.

The inner ring shafting structure is the free beam form.

Inner ring axle system is driven and control by drive motor 11, and inner ring axle system comprises test bearing 6, load bearings 8, bearing 9 and inner ring axle 7; Drive motor 11 is connected with inner ring axle 7 by shaft coupling 10, the two ends of inner ring axle 7 are respectively charged in the inner ring of bearing 9 and load bearings 8, the outer ring of bearing 9 is fixed on the pedestal of testing machine, the outer ring of load bearings 8 and radial loaded device are hinged, as arrow direction among Fig. 1, radial load directly acts on the outer ring of load bearings 8 by loading piston, passes to test bearing 6 then, and the other end of inner ring axle 7 is packed in the inner ring of test bearing 6.

As can be seen, in this shafting structure, test bearing 6 promptly is the cantilever point of outer ring axle system, is again simultaneously the fulcrum of inner ring axle system, can realize two lasso rotations of test bearing 6 by this structure.

The utility model to test bearing according to its velocity spectrum, when loading spectrum carries out the performance simulation test, by drive motor 1, drive motor 11 drives outer ring axle 4 respectively, inner ring axle 7, the inner ring of bearing 3 and bearing 5 and outer ring axle 4 are fixed as one with 4 rotations of outer ring axle, the other end inwall of outer ring axle 4 and the outer ring of test bearing 6 are fixed as one with 4 rotations of outer ring axle, inner ring axle 7 is fixed as one with 7 rotations of inner ring axle with the inner ring of bearing 9 and load bearings 8, the inner ring of test bearing 6 and inner ring axle 7 are fixed as one with 7 rotations of inner ring axle, the outer ring of bearing 3 and bearing 5 and bearing 9 is separately fixed on the pedestal of testing machine and does not rotate, the outer ring of load bearings 8 and radial loaded device are hinged, radial load directly acts on the outer ring of load bearings 8 by loading piston, pass to test bearing 6 then, thereby make test bearing 6 realize the performance simulation test.

The utility model examination is applied to the endurancing of aeromotor intermediary bearing and succeeds.
