What type of axle is used in railway vehicles?

[OElaina]

The wheel axle of a train carriage is a spindle. Here are the specific details: 1. Introduction to axles: An axle is a cylindrical object that passes through the middle of a bearing, wheel, or gear, though a small portion may be square-shaped. It is a mechanical component that supports rotating parts and rotates with them to transmit motion and bending moments. Generally, it is a metal rod with varying diameters along its length. Parts that perform rotational motion in machinery are mounted on the axle. 2. Torsional stiffness verification of the axle: The torsional stiffness verification of the axle calculates the torsional deformation during operation, measured by the angle of twist per meter of axle length. Excessive torsional deformation can affect the performance and operational accuracy of machinery. For example, excessive twist in the camshaft of an internal combustion engine can disrupt the correct opening and closing timing of valves.
