In recent years, the cone
Roller Bearing inner raceway grinding fixture to improve the problem got the extensive concern of the industry, has important significance for the related project. This paper first makes a brief introduction to the related content do, elastic composite
Cylindrical Roller Bearing structure design are analyzed, and combining the related practice experience, from various angles and aspects respectively on elastic composite cylindrical roller bearing a finite element modeling method, this paper expounds the personal views and understanding of this hope help to the practice of the relevant work.
Cylindrical roller bearing need to constantly to overcome the insufficiency of solid cylindrical roller bearing, in the hollow cylindrical roller bearing structure design to improve the hollow shape, reduce the pre-loaded hollow cylindrical roller bearing. If the hollow cylindrical roller has greater flexibility than solid cylindrical roller, need to improve the bearing capacity, according to the roller bearing contact area increase the service life of the bearing. Hollow cylindrical bearing quality size and centrifugal force size to adapt to the speed, improve the structure of the hollow cylindrical roller bearing design, improve the quality of work. Cylindrical roller bearing is a kind of very important machinery components, working performance will directly affect the host performance, need to constantly improve the machinery and equipment complexity, fully improve high-speed, overloading and high precision of extreme working conditions and use rationality, at the same time need for the safety of the cylindrical roller bearing, dynamic performance and improve the bearing capacity requirement.
Hollow cylindrical roller bearing has many advantages, it is necessary to improve the periodic alternation of hollow cylindrical roller, rationality, the guarantee load for the hollow cylindrical roller bending stress in the body to improve the rolling bending fatigue fracture problem, promote the hollow cylindrical roller bearing damage problem solving. Engineering application ability so as to realize the hollow cylindrical roller bearing, meet the requirements of the development of modern machinery, according to the principle of combination of innovation, improve the stress state of roller bearing structure, enhance the bearing capacity, reduce hollow cylindrical roller bending stress, ensure the bearing fatigue life, according to the teaching material physical properties improve bearing noise problem is solved.
