Background

Machines are a general term for machines and mechanisms. The machine is a tool device which can help people to reduce work difficulty or save labor, and articles such as chopsticks, brooms and tweezers can be called as the machine, and the machine is a simple machine. The complex machine is composed of two or more simple machines. These relatively complex machines are often called machines. From a structural and kinematic point of view, the mechanisms and machines are not distinct and are broadly called machines.

The maintenance has three explanations, namely, replacing accessories, maintaining the accessories, modifying according to functions, maintaining and recovering, maintaining and repairing. The common sense of household appliance maintenance comprises mobile phone maintenance, computer maintenance and household appliance maintenance and automobile maintenance. For mobile phones, software updating and upgrading are also included in maintenance items, and for automobiles, rivet prying and spray painting also belong to the maintenance range. The equipment maintenance refers to technical activities performed to restore the functions of equipment after the technical state of the equipment is degraded or fails, and includes various planned repairs, unplanned fault repairs and accident repairs. Also known as equipment repair. The basic contents of equipment maintenance include: equipment maintenance, equipment inspection, and equipment repair.

The rotating shaft is the shaft which is used for connecting main parts of the product and bears bending moment and torque in the rotating work.
