Abstract

The invention discloses a connection pair for a lock nut with a memory alloy ring. The connection pair is used for locking a connected piece and comprises a locking piece with a thread, and a memory alloy gasket arranged on the locking piece in a penetrating manner and making contact with the surface of the connected piece. The connection pair is simple in structure and firm in locking, further has good corrosion resistance and can be used on fastening parts in harsh environments such as ships and the chemical industry.

Description

technical field [0001] The invention relates to the field of fasteners, in particular to a connection pair of lock nuts with memory alloy rings. Background technique [0002] Fasteners are a type of mechanical parts used for fastening connections and are widely used. They are widely used in industries such as energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, and hydraulic pressure. Various fasteners can be seen on various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, instruments and supplies, and are the most widely used machinery. Basic pieces. Fasteners will loosen due to equipment vibration or environmental corrosion during long-term use, causing the connected parts to disintegrate and fall off, resulting in safety accidents or economic losses. [0003] In existing anti-loosening joints, gaskets are usually placed between ordinary nuts and bolts, and the elastic force of...
