so far the school has a national bearing industry has trained nearly 2,000 undergraduate and graduate students . The vast majority of these students have become the backbone of the bearing industry technology , Henan University of Science and Technology has been Precision Bearings hailed as " China 's bearing industry Whampoa Military Academy" insiders . However, the school offers professional bearing more than 60 graduates per year only , can not meet the needs of the country thousands of bearing plant.
Strengthen research and education bearing imminent
Japanese bearings giant wheel bearing its headquarters staff as much as 1800 R & D , which is China bearing counterparts dare not imagine. In many outsiders view, is a kind of simple structure bearing components , it is necessary with so many researchers do ? In fact, we see in everyday life bearings are low -tech low-end bearings , and bearing high degree of technical complexity is low-end bearing can not be compared .
Chinese Academy of Engineering Bingheng believe that high-end research and development related to the bearing material , and lubricating oils , manufacturing , design, bearing manufacturing equipment , testing and other tests a series of technical problems , but also contact mechanics , lubrication theory , tribology , fatigue and damage, heat treatment and organizations and other basic materials research and interdisciplinary .
Precision bearings according to ISO grading standards are divided into: P0, P6, P5, P4, P2. Rank higher in turn, where P0 is the general accuracy, other grades are precision level. Of course, different classification standards, different types of bearings, their classification method somewhat different, but the meaning is to the. The use of performance requirements of precision bearings rotating body with high runout accuracy, high-speed rotation and small changes in friction and friction.
