Achse (als tragendes Bauteil) (陰性)

Description: Axles are drive elements. They transmit movements and forces in drive units, but not torque. Unlike shafts, axles are used to carry, support and act as bearings for mechanical elements such as wheels, Cable drums and rollers. They always have bearings. A distinction is made between: Fixed axles, on which mechanical parts such as cable pulleys rotate freely. The axle is subjected to deflection and shear strain. The ends of the axle, which accommodate the machine parts, are frequently shouldered and are referred to as journals Rotating axles, onto which mechanical parts such as wheels are fixed and which turn in bearings. Because every point on the axle is rotated by compressive and tensile zones, it is subjected to alternating deflection Axles almost always have a circular or annular cross-section. Hollow axles with an annular cross-section exhibit greater stability.
