Bearing engineering meaning
Different bearing types have different operating speed limits. Speed is typically specified as maximum relative surface speeds, often specified ft/s or m/s. Rotational bearings typically describe performance in terms of the product DN where D is the mean diameter (often in mm) of the bearing and N is the rotation … See more A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. The design of the bearing may, for example, provide for free linear movement … See more By far, the most common bearing is the plain bearing, a bearing which uses surfaces in rubbing contact, often with a lubricant such as oil or graphite. A plain bearing may or may not be a discrete device. It may be nothing more than the bearing surface of … See more Common motions permitted by bearings are: • Radial rotation e.g. shaft rotation; • linear motion e.g. drawer; See more Bearing design varies depending on the size and directions of the forces that they are required to support. Forces can be predominately radial, axial (thrust bearings), or See more The invention of the rolling bearing, in the form of wooden rollers supporting, or bearing, an object being moved is of great antiquity. It may predate the invention of a wheel rotating on a plain bearing. Though it is often claimed that the Egyptians used … See more There are at least 6 common types of bearing, each of which operates on a different principle: • See more Reducing friction in bearings is often important for efficiency, to reduce wear and to facilitate extended use at high speeds and to avoid overheating and premature failure of the bearing. Essentially, a bearing can reduce friction by virtue of its … See more Webbearing load has to be calculated based on the bearing loads acting on the bearing via the wheelset journal and the axlebox housing . For railway applications, it is preferable to calculate the life expressed in operating mileage, in million km where L10s = basic rating life (at 90% reliability), million km Dw = mean wheel diameter, m
