Combined interlocking nut

Abstract

The invention provides a combined interlocking nut which comprises a multi-claw nut, a conical face nut and a bolt. Threaded through holes which are in threaded connection with the bolt are formed in the center of the multi-claw nut and the center of the conical face nut. A plurality of deformation claws which are arranged along the periphery of the threaded through hole of the multi-claw nut are arranged on the end face of one side of the multi-claw nut, and the top surface of each deformation claw is a plane. The inner side face and the outer side face of each deformation claw are in a circular arc shape, the radian of each circular arc is same as the radian of the threaded through hole of the multi-claw nut, the outer side face of each deformation claw is a conical inclined face, threads which are matched with the bolt are arranged on the inner side face of each deformation claw, and a deformation groove is formed in the bottom of the inner side face of each deformation claw. An inverted-cone-shaped cavity is formed in the end face of one side of the conical face nut, the inverted-cone-shaped cavity and the threaded through hole of the conical face nut are concentric, the depth of the inverted-cone-shaped cavity is smaller than the thickness of the conical face nut, and the deformation claws of the multi-claw nut are matched with the inverted-cone-shaped cavity of the conical face nut. The combined interlocking nut can effectively prevent mechanical parts from loosening.

Description

technical field [0001] The invention belongs to the technical field of mechanical fasteners, and more specifically relates to a combined interlock nut. Background technique [0002] All kinds of mechanical parts need to be fastened with bolts and nuts that are easy to disassemble. Especially in some fields, such as hammer crushers, the hammer head needs to be replaced at any time as a vulnerable part. Therefore, bolts, The nut fastening method will bear a large impact load during crushing work, causing a large vibration. If the amplitude is too large or resonance is caused, it will have a great impact on the life of the equipment, and even damage the bearings on both sides and cause accidents. Because the impact vibration directly acts on the hammer head, the fastening nut is very easy to loosen, resulting in the drop and loss of the hammer head. This problem is a technical problem that has been plagued by similar equipment. Therefore, it is necessary to develop a nut combi...

[0002] All kinds of mechanical parts need to be fastened with bolts and nuts that are easy to disassemble. Especially in some fields, such as hammer crushers, the hammer head needs to be replaced at any time as a vulnerable part. Therefore, bolts, The nut fastening method will bear a large impact load during crushing work, causing a large vibration. If the amplitude is too large or resonance is caused, it will have a great impact on the life of the equipment, and even damage the bearings on both sides and cause accidents.

Because the impact and vibration directly act on the hammer head, the fastening nut is very easy to loosen, resulting in the drop of the hammer head. This problem is a technical problem that has been plagued by similar equipment.
