This part was proposed by China Machinery Industry Federation.
This part is under the jurisdiction of the National Sliding Bearing Standardization Technical Committee (SAC/TC236). Responsible for drafting this section. China National Machinery Productivity Promotion Center, Shanghai Jiaotong University. Participating in the drafting of this section. Luoyang Shaft Research Technology Co., Ltd., Xi'an Jiaotong University, Lin'an Dongfang Sliding Bearing Co., Ltd. Feibolin New Materials Co., Ltd.
This part is explained by the National Standardization Technical Committee of Sliding Bearings. introduction
Due to the large number of parameter symbols and terminologies named in multiple ways in the field of sliding bearings, the interpretation of standards and technical documents It is easy to cause misunderstanding in the process. This situation has caused the continuous increase of supplementary definitions and further aggravated the possibility of misunderstanding. This part of GB/T 2889 aims to describe a unified abbreviation symbol system. Plain bearing terms, definitions, classifications and symbols
