Abstract

The invention discloses a novel locknut assembly special for a railway. The assembly comprises a nut and a spring gasket, the side edge of the spring gasket is provided with a notch communicated with an inner gasket body through hole and forms two ends with the free ends inclining upwards and downwards respectively, one end is provided with a protruding strip part further extending outwards in the inclining direction of the end, and the position, surrounding a threaded hole, of the nut is provided with an arc-shaped through groove allowing the protruding strip part to penetrate through. The spring gasket with the two ends with the free ends inclining upwards and downwards respectively is arranged between a to-be-connected piece and the nut, the nut can be pushed to be slightly away from the to-be-connected piece through elastic force, so that the internal thread of the nut and the external thread of a screw rod of a bolt are locked, and the anti-loosening effect is achieved; and the protruding strip part penetrating through the arc-shaped through groove of the nut is arranged on one end, so that the protruding strip part can be actively supported by a hand, the elastic force of the spring gasket is counteracted, and the nut is convenient to disassemble.

Description

【Technical field】 [0001] The invention relates to the technical field of nuts, in particular to the technical field of a novel anti-loosening nut assembly specially used for railways. 【Background technique】 [0002] A nut is a nut, which is a part that is screwed together with a bolt or a screw for fastening. It is divided into several types such as carbon steel, stainless steel and non-ferrous metal. The existing anti-loosening nuts for railways have the problems of difficulty in disassembly, poor anti-loosening effects, and the like. In addition, in order to improve the hardness and strength of the nut, it is usually necessary to perform quenching heat treatment on the nut. However, nuts through traditional quenching heat treatment still cannot be used for a long time in extreme environments such as high temperature and high pressure or acid and alkali. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and p...
