From the perspective of heat transfer, hydraulic pump and hydraulic motor are reversible hydraulic components. Entering working liquid into all kinds of hydraulic pumps can make them work as hydraulic motors; Conversely, when Cycloidal motor of aerial work vehicle When the main shaft bearing of is driven to rotate from the external torque, it can also become the working condition of the hydraulic pump.

From the perspective of heat transfer, hydraulic pump and hydraulic motor are reversible hydraulic components. Entering working liquid into all kinds of hydraulic pumps can make them work as hydraulic motors; On the contrary, when the main shaft bearing of the hydraulic motor rotates from the external torque, it can also become the working condition of the hydraulic pump. Because they have the same basic structural factors - closed capacity that can be changed periodically and the corresponding oil distribution organization.

But, because Which one is good for cycloidal hydraulic motor It is different from the working standards of hydraulic pumps and their characteristics. Therefore, there are still many differences between hydraulic motors and hydraulic pumps of the same type. Firstly, the hydraulic motor should be able to turn forward and backward, so its internal structural symmetry is specified; The range of speed ratio of hydraulic motor must be large enough, especially for its lower stable speed ratio. Therefore, it generally selects roller bearings or negative pressure rolling bearings; Secondly, because the hydraulic motor works under the standard of keyed working pressure oil, it does not need to have self-priming working capacity, but it must have certain original tightness to give the necessary motor torque. Because of this difference, the hydraulic motor and hydraulic pump are similar in structure, but can not work reversibly.
