Problems solved by technology

However, the material composition and smelting process of traditional aluminum alloys cannot better improve the performance of the alloy.
[0006] Aiming at the shortcomings of traditional alloys such as low hardness and non-wear resistance, Publication No. 104975221A discloses a method for manufacturing a train coupling. The train coupling has corrosion resistance, good wear resistance, high yield strength, and strong impact resistance. Advantages of long life
However, alloy steel itself is heavy, and its strength and corrosion resistance cannot meet the needs of use in complex environments

Abstract

The invention belongs to the technical field of metal processing, and in particular relates to an anti-twist jointless coupling. The coupling is made of aluminum alloy, and the aluminum alloy is composed of the following raw materials in mass percentage: silver-impregnated bamboo charcoal: 0.1-0.5%, Si: 0.05-0.5% 0.15%, Zr: 0.1‑0.2%, Ni: 0.04‑0.1%, Co: 0.1‑0.2%, the balance is Al and impurities, and the coupling is prepared through pretreatment, smelting, powder forming, finished products and other processes , through the improvement of the raw material formula and the use of cyclic hydrogenation-dehydrogenation, not only the particle size of the suitable coupling alloy can be obtained, but also the content of impurity elements present in the alloy can be significantly reduced.

Description

technical field [0001] The invention relates to an anti-twist jointless shaft coupling, which belongs to the field of metal materials. Background technique [0002] Coupling refers to a device that connects two shafts or shafts and rotating parts, and rotates together during the process of transmitting motion and power, and does not disengage or change the direction of rotation and torque under normal conditions. Sometimes it is also used as a safety device to prevent the connected parts from bearing excessive loads and to protect against overload. Couplings are a commonly used component in mechanical products. [0003] Couplings are often composed of two halves, which are respectively connected by keys or tight fits, fastened at the ends of the two shafts, and then the two halves are connected in some way. And there will be defects with low force capacity at the connection, which is easy to cause breakage or bending. [0004] It can be seen that the performance of the cou...
