Mechanical maintenance mainly introduces the general knowledge of mechanical transmission and parts such as mechanism, belt transmission, gear transmission, coupling and clutch. It also introduces the general concept of hydraulic transmission, the basic principle of hydraulic transmission system, hydraulic components and basic circuits, and the basic knowledge of motor and control.

"Mechanical Road Maintenance" is a textbook for railway engineering majors in higher and secondary vocational colleges, and can also be used as a reference for railway related professional and technical personnel.

Content introduction:

Mechanical Maintenance introduces the principle, structure, operation, maintenance, analysis and troubleshooting methods of common maintenance machinery in railway line maintenance. Through learning, students can improve the use of various road maintenance machinery.

The classification, working principle and basic structure of internal combustion engine are also introduced. According to the needs of railway maintenance, this paper mainly introduces some commonly used road maintenance machinery, such as tamping machine, screening machine, rail moving machine, rail gap regulator, hydraulic square sleeper, hydraulic rail straightener, rail cutter, rail drilling machine, 08-32 comprehensive tamping car, RM80 ballast screening machine, dynamic stabilizing car, ballast shaping car, turnout grinding car, maintenance car and so on. The principle and characteristics of these machines are analyzed.
