Bearings types

Other Selection Problems. Additional considerations can arise when fans must handle soHds or gases of low density, or must be operated in parallel or series. A compHcated flow system involving several fans in parallel, all of which are ia series with a common exhaust fan, can lead to surging and vibration unless selected carefully. Maximum tip speed, bearing types, single- and double-inlet fans, and wheel and shaft natural frequency and rigidity must also be considered. [Pg.109]

Type I, soft alloys (20—22-carat golds), are used for inlays of simpler non-stress-bearing types. Type I gold alloys can be burnished, and are not heat-treatable. They are composed essentially of gold—silver—copper with minor modifying additions, eg, zinc. [Pg.483]

Cylindrical hore heatings. Another common bearing type used in turbines. It has a spht construction with two axial oil-feed grooves at the spht. [Pg.943]

Thrust-Bearing Power Loss The power consumed by various thrust bearing types is an important consideration in any system. Power losses must be accurately predicted so that turbine efficiency can be computed and the oil supply system properly designed. [Pg.945]

Link-Suspended Basket Centrifuges In centrifuges with diameters larger than 762 mm (30 in), the basket, curb, curb cover, and drive form a rigid assembly flexibly suspended from three fixed posts (also known as a three-column centrifuge). The three suspension members may be either chain hnks or stiff rods in ball-and-socket joints and are spring-loaded. The suspended assembly has restrained freedom to oscillate to compensate for a normal out-of-balance condition. The drive is vertical with more efficient power transmission compared to the base-bearing type. [Pg.1735]

Two-bearing screens, ot which there are rnanv types, have the same screen boclv as the four-bearing type but without the two outer bearings and the base frame. The gyi ating motion is caused bv eccentric weights on the shaft, and the screen itself is supported bv overhead cables or springs on the floor. [Pg.1773]

There are many roller bearing types. They are differentiated aeeording to the direetion of the main radial loads (radial bearings) or axial loads (thrust... [Pg.470]

A variety of bearing types is used in gearboxes. Narrowband windows should be established to monitor the rotational and defect frequencies generated by the specific type of bearing used in each application. [Pg.704]
