公元前221～207年的秦代中国出现了滚动支承,但直到第二次世界大战结束,中国仍没有独立的滚动轴承科研生产体系,甚至不能独立生产滚动轴承四元件(内外套圈、滚动体、保持架)。1949年,中国(不含港、澳、台,下同)滚动轴承产量仅13.8万套。20世纪50年代以来,中国滚动轴承工业的发展经历了计划经济和市场经济两个时期。计划经济历经奠基、体系形成和开放发展三个阶段。目前正处于市场经济初期。本文简述这一历史发展过程。
The Qin Dynasty 221 ~ 207 BC appeared rolling support in China, but until the end of World War II, China still does not have an independent rolling bearing research and production system, can not even independently produce four elements of rolling bearing (inner and outer rings, rolling body, keep frame). In 1949, China (excluding Hong Kong, Macao and Taiwan, the same below) rolling bearing production was only 138,000 units. Since the 1950s, the development of rolling bearing industry in China has experienced two periods: planned economy and market economy. Planned economy has gone through three stages: foundation laying, system formation and opening up. Is currently in the early stages of market economy. This article briefly describes this process of historical development.
