Bearing Specification For Hydraulic Motor

From the point of view of energy conversion, hydraulic pump and hydraulic motor are reversible hydraulic components, to any kind of hydraulic pump into the working fluid, can make it into a hydraulic motor working condition; Conversely, when the spindle of the hydraulic motor is rotated by the external torque, it can also be changed into a hydraulic pump working condition. Because they have the same basic structural elements-closed and can be cyclical changes in volume and the corresponding oil distribution agencies.Hydraulic Motor

Because of the different working conditions of the hydraulic motor and the hydraulic pump, the performance requirements are not the same, so there are still many differences between the same type of hydraulic motor and the hydraulic pump. First, the hydraulic motor should be able to reverse, and thus require its internal structure symmetry; The speed range of the hydraulic motor needs to be large enough, especially for its lowest stable speed.Hydraulic Motor

As a result, it usually adopts rolling bearing or hydrostatic bearing; Secondly, the hydraulic motor is not required to have the self-priming ability because of the operation under the condition of the input pressure oil, but it needs some initial sealing property to provide the necessary starting torque. Because of these differences, hydraulic motors and hydraulic pumps are structurally similar, but not reversible.Hydraulic Motor
