A Rexroth hydraulic motor is an actuator of a hydraulic system that converts the liquid pressure energy provided by a hydraulic pump into the mechanical energy (torque and speed) of its output shaft.
Hydraulic motors, also known as oil motors, are mainly used in injection molding machinery, ships, hoists, construction machinery, construction machinery, coal mining machinery, mining machinery, metallurgical machinery, ship machinery, petrochemical industry, port machinery, etc.
The high-speed motor gear motor has small size, light weight, simple structure, good manufacturability, insensitive to oil pollution, and impact resistance.
Features of Rexroth hydraulic motors
From the point of view of energy conversion, the hydraulic pump and the hydraulic motor are reversible hydraulic components, and the input of working liquid to any kind of hydraulic pump can make it become a hydraulic motor working condition; Conversely, when the spindle of the hydraulic motor is driven by external torque to rotate, it can also be changed to the hydraulic pump working condition. Because they have the same basic structural elements - a closed and periodically variable volume and the corresponding oil distribution mechanism.
However, due to the different working conditions of hydraulic motors and hydraulic pumps, the performance requirements for them are also different, so there are still many differences between the same type of hydraulic motors and hydraulic pumps.
Rexroth Hydraulic MotorThe hydraulic motor should be able to rotate forward and reverse, so its internal structure is required to be symmetrical; The speed range of the hydraulic motor needs to be large enough, especially for its low stable speed. Therefore, it is usually used in rolling bearings or hydrostatic plain bearings; Secondly, the hydraulic motor does not have to be self-priming because it works under the condition of input pressure oil, but it needs a certain initial tightness to provide the necessary starting torque. Due to these differences, hydraulic motors and hydraulic pumps are similar in structure, but they cannot work reversibly.

Analysis of the fault phenomenon and causes of Rexroth hydraulic oil pump
1. Check the internal leakage of the boom cylinder. The easiest way to do this is to raise the boom and see if it has a noticeable free descent. If the drop is obvious, disassemble the cylinder for inspection, and replace the sealing ring if it is worn;
2. Check the control valve. First of all, clean the safety valve and check whether the valve core is grinding.

Rexroth Hydraulic Pumps - What are the hazards of hydraulic pumps entering the air?
First, the rigidity of the hydraulic oil decreases sharply, resulting in the slower response of the hydraulic system and the reduction of efficiency, resulting in crawling and vibration of the actuator.
Second, air bubbles will cause oil film to be unable to form between moving parts, resulting in poor lubrication and aggravating the wear of hydraulic components.
The third is in the air ...
