Compared with the power transmission, the main advantages of the hydraulic transmission are as follows:
(1) small quality and small size. This is because the motor is limited by magnetic saturation, and the tangential force on the unit area is a few times that of the hydraulic pressure that the hydraulic machinery can bear.
(2) the motion inertia is small and the response speed is fast. The torque inertia ratio of the hydraulic motor (that is the ratio of the driving torque to the moment of inertia) is much larger than that of the motor, so its acceleration performance is good. For example, it usually takes a second to a few seconds to speed up a medium power motor, and a hydraulic motor that accelerates the same power needs only about 0.1 s. This kind of good dynamic characteristic is more important to the hydraulic control system.
(3) low speed hydraulic motor's low speed stability is much better than motor.
(4) the application of hydraulic transmission can simplify the electrical system of the machine equipment. This is of great benefit to the underground work of coal mine with the danger of explosion.
