机械基础件通称为基础件,是现代传动与控制技术发展的基本元件。主要包括液压、液力、气动、密封、轴承、粉末冶金制品、紧固件、链条、弹簧和齿轮等多类产品,品种繁多,量大面广。大多数基础件是运动件、受力件、易损件和功能部件,直接决定着主机的性能、水平和质量。目前,我国许多主机可靠性差、寿命短、性能低、质量不稳定等大都与基础件有关。随着科学技术的发展,现代传动与控制技术、高水平的主机对基础件的要求已越来越高,特别是与自动化水平直接相关的传动与控制元件,如液压、气动元件、密封件及精密、高寿命、低噪声轴承
Known as the basic parts of the basic mechanical parts, is the basic components of the development of modern transmission and control technology. Mainly include hydraulic, hydraulic, pneumatic, seals, bearings, powder metallurgy products, fasteners, chains, springs and gears and other products, a wide variety, a wide range of products. Most of the basic parts are moving parts, force parts, wearing parts and functional components that directly determine the performance, level and quality of the host machine. At present, many hosts in our country have poor reliability, short service life, low performance and unstable quality, which are mostly related to the basic parts. With the development of science and technology, modern transmission and control technology, high-level host of the basic requirements of the increasingly high, especially with the level of automation directly related to transmission and control components, such as hydraulic, pneumatic components, seals and Precision, high life, low noise bearings
