Bearings are mechanical assemblies that consist of rolling elements and usually inner and outer races which are used for rotating or linear shaft applications, and there are several different types of bearings, including ball and roller bearings, linear bearings, as well as mounted versions that may use either rolling element bearings or plain bearings. Ball bearings have spherical rolling elements and are used for lower load applications, while roller bearings use cylindrical rolling elements for heavier load carrying requirements. Linear bearings are used for linear movements along shafts and may also have rotational capabilities. Mounted bearings are assemblies in which the bearings are pre-assembled in mountings that, in turn, are bolted to frames, stanchions, etc. In addition to ball and roller bearings in their radial, linear, and mounted forms, bearings include those for civil engineering applications, which are called slide bearings; those used in small instruments and the like, known as jewel bearings; and very specialized bearings known collectively as frictionless bearings which includes air and magnetic varieties.

Artificial Intelligence Al is an emerging technology. Research in Al is focused on developing computational approaches to intelligent behavior. The computer programs with which Al could be associated are primarily symbolic processes associated with complexity, ambiguity, indecisiveness, and uncertainty. One of these computer programs is referred to as Knowledge-based Expert System as it represents knowledge acquired from various experts in a particular field of interest to the user. In this paper, the application of Knowledge-based Expert System to aid the design of ball and roller bearings is discussed. The precision rolling-element bearings of twentieth century is a product of exacting technology and sophisticated science. A bearing supports radial and axial loads, at the same time allowing relative motion between two elements of a machine.

January 1, January ; 1 : — A new, general and consistent mathematical model of highly modular character is presented for calculation of the equilibrium and associated load distribution in rolling element bearings. The bearings may be loaded and displaced in five degrees of freedom. High speed rolling element loading is considered, internal friction is neglected, the material is assumed linearly elastic and the bearing rings are modelled as rigid except for local contact deformation. Either classical Hertzian contact analysis or modern non-Hertzian contact analysis of sophisticated or approximate character is used as applicable. The bearing stiffness matrix is computed analytically and used internally in the iterative bearing equilibrium calculation; its final values may be used for other purposes such as rotor dynamics analysis.

Нужно было думать о долге - о стране и о чести. Стратмор полагал, что у него еще есть время. Он мог отключить ТРАНСТЕКСТ, мог, используя кольцо, спасти драгоценную базу данных. Да, подумал он, время еще. Он огляделся - кругом царил хаос.

Четыре. Три. Эта последняя цифра достигла Севильи в доли секунды. Три… три… Беккера словно еще раз ударило пулей, выпущенной из пистолета. Мир опять замер .

Похоже, она от меня не отвяжется. И он решил не реагировать на сообщение. ГЛАВА 79 Стратмор спрятал пейджер в карман и, посмотрев в сторону Третьего узла, протянул руку, чтобы вести Сьюзан за. - Пошли.

Дэвид Беккер повесил трубку. Альфонсо XIII. Он усмехнулся. Просто надо уметь задавать вопросы… Минуту спустя незаметная фигура проследовала за Беккером по калле Делисиас в сгущающейся темноте андалузской ночи.

К несчастью для того, кто это придумал, коммандер Стратмор не нашел в этой выходке ничего забавного.

A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts.
