Hydraulic motor yes Hydraulic transmission An implementation component of the system, which changes the liquid pressure energy given by the hydraulic oil pump into the mechanical kinetic energy (torque and speed ratio) of its output shaft. Liquid is a substance that transmits force and motion. Key applications include injection molding processing machinery, ships, hoists, engineering machinery, construction machinery, coal mining machinery, mining equipment, metallurgical equipment, ship accessories, petrochemical equipment, port machinery, etc. The following is a detailed introduction to the basic concepts of the hydraulic motor driver for everyone to share.

Low speed hydraulic motor is used for high pressure oil inlet and outlet, and pump is used for suction and discharge of high pressure oil

Low speed hydraulic motor: basic concept of driver of hydraulic motor

The low-speed hydraulic motor is used for high pressure oil inlet and outlet, and the pump is used for suction and discharge of high pressure oil.

     Swing hydraulic motor The gear shaft of the pump is connected with the gear shaft of the pump (coaxial output) to promote the pump rotation when the hydraulic motor rotates.

The hydraulic oil pump and hydraulic motor are hydraulic fittings that can be used in cross operation. The liquid input to all kinds of hydraulic oil pumps can make them become the working conditions of hydraulic motors; Conversely, when the machine tool spindle bearing of the low-speed hydraulic motor rotates by the external torque driver, it can also become the working condition of the hydraulic oil pump. Because they have the same basic structural elements, closed volume and recyclable relative oil distribution mechanism.

There are still many differences between the same type of swing hydraulic motor and hydraulic oil pump. Because the working specifications of hydraulic motor and hydraulic oil pump are different, the requirements for their characteristics are also different. The hydraulic motor should be able to rotate forward, so its internal structure is required to be symmetrical; The transmission ratio range of the slewing hydraulic motor should be sufficient and large, especially when there are requirements for its stable transmission ratio. Therefore, it generally adopts needle bearing or negative pressure roller bearing; Secondly, the low-speed hydraulic motor does not have the self-priming professional ability because it works under the input pressure oil specification, but it can provide the essential motor torque only with the initial sealing. It is also because of this kind of difference that the structural characteristics of the rotary hydraulic motor and the hydraulic oil pump are relatively similar, but they cannot work in a cross way.
