Abstract

The invention discloses a high-torque-resistance-prevention nut which comprises the following components in percentage by weight: 10-25% of ferrum, 1.2-5.5% of titanium, 5-15% of aluminum, 50-100ppm of rhodium, 30-70ppm of osmium, 120-300ppm of iridium, 50-100ppm of indium, 0.05-0.8% of rear-earth metal and the balance of magnesium and impurities brought in during preparation. The high-torque-resistance-prevention nut provided by the invention has great elasticity and high torque resistance prevention, can play effects of looseness prevention and shock resistance, can improve the reliability, and can be used repeatedly.

Description

technical field [0001] The invention relates to the field of mechanical parts, in particular to a nut with high torque resistance. Background technique [0002] A nut is a nut, a part that is screwed together with a bolt or a screw for fastening, and is an element that must be used in all manufacturing machinery. There are many kinds of nuts. According to different materials, nuts are divided into several types such as carbon steel, high-strength, stainless steel, and plastic steel. [0003] The quality of the nut plays a key role in the operation of the entire mechanical equipment. The material of the currently used nut does not have a large elastic force and high torque resistance, it is easy to loosen, the shockproof effect is not good, and it cannot be used repeatedly. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a nut with high elastic force and high torque resistance, which can prevent loosening and sh...
