Problems solved by technology

[0002] For general flexible couplings, when the load of the unit is too large, it is easy to cause permanent damage to the flexible parts, thereby affecting the service life of the coupling
When the torque overload of the unit exceeds a certain range, the flexible member will fail. At this time, a speeding situation may occur and cause damage to other equipment of the unit.

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the embodiments in the accompanying drawings:

[0014] like Figure 1~2 As shown, the present invention mainly includes an adapter shaft 1, a flexible member 2 and an adapter plate 3, one end of the adapter shaft 1 is provided with a bearing flange 5, and one end of the adapter plate 3 is provided with the same structure as the bearing flange 5 The load-bearing counterbore 6 of the adapter shaft 1 extends into the load-bearing counterbore 6 of the adapter plate 3 .

[0015] There is a certain gap between the bearing flange 5 and the bearing counterbore 6 .

[0016] like figure 2 In the shown embodiment, the bearing flange 5 is a polygonal structure. In another embodiment, each straight side of the bearing flange 5 may also be set as a circular arc side.

[0017] One side of the adapter plate 3 is provided with a flexible piece 2 , and the flexible piece 2 is fastened to the adapter plate 3 an...

Abstract

The invention relates to an overload protection structure for a coupler, in particular to a structure for protecting flexible parts of the coupler when the torque is overloaded, and belongs to the technical field of couplers. The overload protection structure comprises an adapter shaft, the flexible parts and an adapter disc, a bearing flange is arranged at one end of the adapter shaft, a bearingcountersunk hole of which the appearance outline is the same as the structure of the bearing flange is formed in one end of the adapter disc, and the bearing flange of the adapter shaft stretches intothe bearing countersunk hole of the adapter disc; and the flexible parts are arranged on one side of the adapter disc and fastened on the adapter disc and the bearing flange through multiple connecting parts. According to the overload protection structure for the coupler, through the rigid connecting structure of the countersunk hole and the flange, a part of loads can be borne when the coupler is overloaded, and damage of the flexible parts is avoided; meanwhile, galloping is avoided when the flexible parts fail, and other equipment of a unit is effectively protected.

Description

technical field [0001] The invention relates to an overload protection structure of a coupling, in particular to a structure suitable for protecting a flexible part of a coupling when the torque is overloaded, and belongs to the technical field of couplings. Background technique [0002] For general flexible couplings, when the load of the unit is too large, it is easy to cause permanent damage to the flexible parts, which in turn affects the service life of the coupling. When the torque overload of the unit exceeds a certain range, the flexible member will fail. At this time, a speeding situation may occur and other equipment of the unit may be damaged. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a coupling overload protection structure, which can bear a part of the load when the coupling is overloaded, and avoid damage to the flexible parts; at the same time, avoid flying when the flexib...
