Background

Shaft (shaft) is a cylindrical object that passes through the middle of the bearing or the middle of the wheel or gear, but is also a small part of square. A shaft is a mechanical part that supports and rotates with a rotating part to transmit motion, torque, or bending moment. Typically in the form of a metal round rod, the segments may have different diameters. The parts in the machine that are in rotary motion are mounted on the shaft. Wheel axles, as the name implies, are systems consisting of "wheels" and "axles". The system can rotate around a coaxial line, and is equivalent to a lever system taking the axle center as a fulcrum and taking the radius as a rod.

The shaft is used as a support, the wheel carries out a rotating supporting rod, the supporting rod bears the torsion of the wheel and the gravity of the supporting rod, in the practical application process, when the weight of an object loaded by the device is heavy or the smooth torque on the wheel is overlarge, if the hard strength of the shaft is insufficient, the phenomenon of shaft breakage is easy to occur, and the use stability of the shaft lever is reduced.
