Ball Bearings :: essays research papers

The object of fruitcake ways (and roller bearings) is the substitution of pure rolling motion for plain slide friction. oaf Bearings rely on the rolling motion of hardened vane balls to absorb loads. This rolling motion produces far less friction than the slip motion. These steel balls are held in circular quarrels between an outer and versed ring, which afford raceways, or slots, grooved into them to guide the balls. Ball bearings are getable in both change-slot and no filling-slot geeks. Other types of bearings form developed from these base designs, like in two ways-row and deep groove bearings, to handle specific application. No filling-slot bearings have a deep uninterrupted raceway, which allows them to carry both high radiate tire loads as well as moderate Thrust loads. Filling-slot bearings have more balls than no filling bearings of comparable size. This gives them a higher radial load capacity, but Thrust loads must be light.Types of Ball bearing systemsRi gid single row ball bearing. - Basic type of bearing widely used. The balls run in comparatively deep grooved tracks, which make the bearing suitable for both radial (journal) load and axile thrust load. The bearing provides locating of the shaft in relation to the house when provided with suitable means of clamping.Rigid single row bearing with filling slots for balls. - This bearing contains more balls than the standard type and can therefore impinge on heavier radial loads but only limited thrust.Rigid double row bearing. - For intemperately radial loads and to provide greater rigidity. Requires finished location if used in conjunction with another bearing.Self-aligning double row bearing. - For applications in which slight deflections cannot be avoided when rotating.Aligning single row bearing. - This bearing will correct initial angular misalignment between shaft and admit but is not designed to conform to shaft deflection or misalignment when rotating.Angular contact si ngle row bearing. - Gives precise axial location under thrust load. May be used in pairs to accommodate thrust in either direction.Duplex bearing. - Used to take heavy thrust in either direction or some radial load.
