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
The present invention relates to mechanical Component field, particularly relate to a kind of nut with high torque resistant resistance.
Background technique
Nut is exactly nut, and with the part that bolt or screw rod are screwed in to play the role of fastening, all manufacture a kind of element of the necessary usefulness of machinery.Nut of a great variety, nut is divided into several large types such as carbon steel, high strength, stainless steel, plastic-steel according to the difference of material.
The quality of nut plays key effect to the operation of whole machinery, and the material of the nut that uses does not at present originally possess larger elastic force and high torque resistant resistance, and easily loosening, shockproof effect is bad, and can not Reusability.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of have larger elastic force and high torque resistant resistance, can play locking and anti seismic efficiency, and repeatedly used nut with high torque resistant resistance.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of nut with high torque resistant resistance is provided, and its each compositions in weight percentage content is counted: the impurity of bringing into when iron 10-25%, titanium 1.2-5.5%, aluminium 5-15%, rhodium 50-100 ppm, osmium 30-70 ppm, iridium 120-300 ppm, indium 50-100 ppm, rare earth metal 0.05-0.8%, surplus are magnesium and preparation.
In a preferred embodiment of the present invention, the content of described impurity in whole nut is less than or equal to 0.08%.
In a preferred embodiment of the present invention, the content of the zinc in the described impurity is less than 0.005%.
In a preferred embodiment of the present invention, described rare earth metal comprises scandium, yttrium and ytterbium.
In a preferred embodiment of the present invention, the content of described ytterbium is less than or equal to 0.05%.
The invention has the beneficial effects as follows: the present invention has larger elastic force and high torque resistant resistance, can play locking and anti seismic efficiency, has improved the reliability of nut, but and Reusability.
Embodiment
The below is described in detail preferred embodiment of the present invention, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
