Abstract

The invention aims to provide a high-strength powder metallurgy brass-based coupler. The high-strength powder metallurgy brass-based coupler comprises the following components by mass percent: 28-32% of Zn element powder, 0.5-0.7% of rare earth element powder and the balance of copper powder and inevitable impurities. The technical problem that the dimensional consistency is difficult to guarantee because many variables exist during traditional machining is solved.

Description

technical field [0001] The invention relates to the field of bearing manufacturing, in particular to a high-strength powder metallurgy brass-based coupling. Background technique [0002] Couplings are the most commonly used connecting parts for shaft transmission of mechanical products. In the late 20th century, domestic and foreign coupling products developed rapidly. When designing products, how to choose a coupling that can meet the requirements of the machine from a variety of couplings with many varieties and different performances is a difficult task for most designers. Always a nagging question. Commonly used couplings include diaphragm couplings, gear couplings, plum blossom couplings, slider couplings, drum gear couplings, universal couplings, safety couplings, elastic couplings Device and serpentine spring coupling. [0003] At present, couplings are increasingly used in precision machinery controlled by servo systems, such as machine tools and semiconductor sys...
