Normal balance locknut and locking method thereof

Abstract

The invention discloses a normal balance locknut and a locking method thereof. The normal balance locknut comprises a nut body and a wedge-shaped gasket, and the wedge-shaped gasket is arranged on the end face of the nut body. The wedge-shaped gasket is additionally arranged to lift one side of the nut body, so that a spiral line of the nut body tends to be horizontal, and a component force for counteracting a lead angle can be generated in the screwing process. A cavity is formed in the middle section of the nut body, the installed nut body can incline under the action of the wedge-shaped gasket, seen from a profile map, one half of thread can be close to the axis of a screw, the other half of thread can be far away from the axis of the screw, and the half circle of thread close to the axis of the screw can generate a radial pressing force. In the working state, when the nut body is screwed, an axial locking force is generated, meanwhile, a component force for balancing the lead angle of the thread and a radial force for tightly pressing the screw are generated, under the action of the last two forces, the screw can be locally bent, a thread angle of the bent screw is changed, the deformed thread is difficult to rotate, and the locking purpose is achieved.

Description

technical field [0001] The invention relates to the technical field related to nuts, in particular to a normal balance nut and an anti-loosening method thereof. Background technique [0002] In many industries, vibration and anti-loosening have always been difficult to solve in a very economical way. The convex-concave nut of Japan Hadlock Company is recognized as the best anti-loosening nut at present. It not only has the axial fastening force, but also the radial locking force of the thread itself. The figure given on its official website It can be seen from the demonstration that the anti-loosening force comes from an eccentric cone in the radial direction placed between two nuts like a wedge, but the structure of the above-mentioned anti-loosening nut is complicated, and the production and cost are high. We create conditioning. [0003] Therefore, a normal balance nut and its anti-loosening method are proposed. Contents of the invention [0004] The purpose of the p...
