Rolling bearings generally consist of the following four basic components: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Inner ring, outer ring, cage and roll body counter-center or centripetal thrust bearing (inner or outer ring can be collectively referred to as ferrule); shaft ring, race, cage and roll body for thrust or thrust radial bearing (The shaft ring or race can be collectively referred to as a washer).
Having a tumbler is the fundamental layout feature of a tumbling bearing; a small number of tumbling bearings are used to save space orientation; or to accommodate more tumbling bodies; can be without outer or inner ring; without inner or outer ring; or without Cage; however, all rolling bearings must have a roll.
Generally, the inner ring or the shaft ring is mounted on the shaft; the outer ring or the seat ring is installed in the bearing housing hole; and the rolling body is installed between the inner and outer rings or between the shaft and the race. The external load passes through the inner ring of the rolling body or The shaft ring is transmitted to the outer ring or the seat ring; or the outer ring or the seat ring is transmitted to the inner ring or the shaft ring; the two sides are rotated by the rolling body to complete the relative transformation. The cage is used to separate the rolling body; to prevent the rolling bodies from touching each other The relative speed of the roll touch is roughly one times the tumbling speed of the single roll; this will cause the roll of the roll.
The interests and shortcomings of the rolling bearing are mostly related to the existence of the rolling body; for example, the rolling friction constitutes the rolling friction; the static and dynamic friction coefficient is low; the transmission efficiency is high; the axial dimension. The ankle ring is used to repair the hook and sputum benzoquinone (" Point "touch or "line" touch); so that the rolling bearing stiffness, oscillation, noise and other quality is not as good as some types of sliding bearings; radial scale is also larger.
