Compared with mechanical transmission and electrical transmission, hydraulic transmission has the following advantages:
1. Various components of hydraulic transmission can be conveniently and flexibly arranged according to needs.
2. Lightweight, small in size, low in motion inertia, and fast in response speed.
3. Easy to operate and control, capable of achieving a wide range of stepless speed regulation (speed regulation range up to 2000:1).
4. It can automatically implement overload protection.
5. Mineral oil is generally used as the working medium, and the relative motion surface can self lubricate with a long service life.
6. It is easy to achieve linear motion.
7. It is easy to achieve machine automation. When using electro-hydraulic joint control, not only can a higher degree of automatic control process be achieved, but also remote control can be realized.
