1) transmission stability in the hydraulic transmission equipment, because the reduction of oil is very small, under the general working pressure, 40T high-speed punch can not feel the reduction, with the continuous flow of oil to carry out transmission. The oil has the ability to work with vibration absorption, and can also set the hydraulic cache equipment in the oil passage, so it is not like the mechanical equipment due to the production and processing and installation of the deviation will cause the vibration buckle collision, so that the transmission is very stable, easy to complete the frequent phasing; Therefore, 45T high-speed punch is widely used in the provision of stable transmission of mechanical equipment, such as CNC grinder basically all use of hydraulic transmission.

2) light weight small body hydraulic transmission and mechanical equipment, electrical engineering and other transmission methods, in the output of the same output power standard, volume and mass can be reduced a lot, so the inertia force is small, flexible posture; This is especially critical for hydraulic profiling, hydraulic automatic control systems, and equipment that specifies relief quality. For example, after the use of hydraulic transmission, the quality of the 1 meter 3 excavator manufactured in our country alleviates 1T compared with the use of mechanical equipment transmission.

3) large bearing capacity hydraulic transmission is easy to get very large force and rotation, so it is widely used to restrain the machine, tunnel boring machine, ten thousand ton cargo ship steering gear and ten thousand ton hydraulic press, etc.
