Webb6 okt. 2016 · The first is the tapered-roller bearing, which uses cone-shaped rollers, which run on conical conical races. They have a greater contact area than ball bearings, so they can carry higher loads. They also support both radial and axial loads. Spherical-roller bearings are self-aligning, double-row, combination radial and thrust bearings. Webb13 juni 2024 · The bearings serve to reduce friction and allow for smoother rotation. This cuts down on the amount of energy consumption. This is the single most important function of bearings. Function 2: Protect the part that supports the rotation, and maintain the correct position for the rotating shaft WebbKeep shafts as short as possible with the bearings close to applied loads. This will reduce shaft deflection and bending moments and increase critical speeds. • If possible, locate stress raisers, such as sharp radii, slots, and changes in diameter, away from highly stressed regions of the shaft. fly til usa
