like figure 1 As shown, the correct way to install the bolted connection pair of the laminated flexible coupling is to penetrate and fix the shear torsion bolt from the end of the active side flange; figure 2 As shown, in fact, the shear torsion transmission bolts will be installed in the wrong direction when installed in the field. Since the shear torsion transmission bolts bear large shear stress and extrusion stress, after the bolts are installed in the wrong direction, the flange installation edge The effective area under extrusion is reduced, which will easily lead to the crushing of the flange mounting edge, which will cause the shear torsion bolts to bear an additional large bending moment on the basis of shear and extrusion, resulting in premature bolt failure. Failure, resulting in damage to the laminated flexible coupling, resulting in equipment quality accidents

Embodiment Construction
[0012] The present invention will be further described below with reference to the specific drawings and embodiments.
[0013] like Figure 3~5 As shown, it includes shearing torsion bolt 1, threaded part 1-1, polished rod part 1-2, shaft shoulder 1-3, active side flange 2, plate group 3, bushing 4, step hole 4-1, self Lock nut 5, driven side flange 6, etc.
[0014] like Figure 3~5 As shown in the figure, the present invention is a laminated flexible coupling structure for preventing mis-installation, including the active side flange 2 and the driven side flange 6 used in cooperation with each other, and the plate group 3 is clamped and arranged on the active side method. Between the flange 2 and the driven side flange 6, a bushing 4 is arranged in the inner hole of the driven side flange 6, and a stepped hole 4-1 is arranged in the center of rotation of the bushing 4, and the screw of the torque transmission bolt 1 is sheared. Passing through the connecting holes of the a...

The invention belongs to and relates to a wrong assembly preventing structure of a lamination flexible coupling, in particular to a lamination flexible coupling structure for preventing wrong assembly. The structure comprises a driving side flange and a driven side flange fitting for use, wherein a piece set is clamped between the driving side flange and the driven side flange; a bushing is arranged in an inner hole of the driven side flange; a step hole is formed in the revolving center of the bushing; and a screw rod of a shearing torque transmission bolt penetrates through connecting holes of the driving side flange, the piece set and the driven side flange in sequence. Through special structural design of the shearing torque transmission bolt and the bushing, a bolt connecting pair only can be assembled in a correct direction, and the wrong assembly possibility of the bolt connecting pair is prevented in structural design.
Description
technical field [0001] The invention belongs to a structure for preventing misassembly of a laminated flexible coupling, in particular to a structure for preventing misassembly of a laminated flexible coupling. Background technique [0002] Coupling is an indispensable connection in mechanical transmission, and the advantage of laminated flexible coupling is that it can compensate the influence of manufacturing error, installation error, deformation after load and temperature change between the driving shaft and the driven shaft. Axial, radial and angular offset caused by etc., so the application of laminated flexible coupling is very common. like figure 1 As shown in the figure, the correct way to install the bolted connection pair of the laminated flexible coupling is to insert the shear torsion bolt from one end of the active side flange and fix it; such as figure 2 As shown in the figure, in fact, the shear torsion bolts are installed in the wrong direction during the...
