The structure, working principle and characteristics of hydraulic gear motor:

In hydraulic transmission, hydraulic gear motor is an important hydraulic component. It is a device that converts hydraulic energy into mechanical energy and can be used in various machinery, such as the slewing mechanism of cranes and excavators.


1. Structure of hydraulic gear motor

Hydraulic gear motors usually consist of a housing, a gear shaft, a plunger, an end cover, etc. Among them, the gear shaft is the core component of the hydraulic gear motor. Together with the plunger, it converts hydraulic energy into mechanical energy. The plunger is one of the key components of the hydraulic gear motor. It is connected to the housing through the end cover and transmits pressure oil to the interior of the housing through the end cover.


2. Working principle of hydraulic gear motor

The working principle of a hydraulic gear motor is to convert hydraulic energy into mechanical energy. When high-pressure oil enters the hydraulic gear motor, the plunger is affected by pressure and transmits the pressure oil to the inside of the housing through the end cover. At this time, the gear shaft rotates under the action of hydraulic pressure, converting hydraulic energy into mechanical energy, thereby driving the load to rotate.


3. Characteristics of hydraulic gear motor

1). High torque output: Hydraulic gear motors have high torque output capabilities and can provide large torque at low speeds, so they are widely used in situations that require high power output.

2). Stepless speed regulation: By changing the flow and pressure of the input hydraulic pressure, the speed of the hydraulic gear motor can be steplessly adjusted to adapt to different work needs.

3). Good starting performance: Since the hydraulic gear motor has a large starting torque and a fast response speed, it has good starting performance and can reach the rated speed in a short time.

4). Easy maintenance: The maintenance of hydraulic gear motors is relatively simple. You only need to regularly check whether the oil circuit is smooth and whether the seals are leaking.

5). High reliability: Since the hydraulic gear motor has high working pressure and rotation speed, it requires high materials and processing accuracy for each component, thus ensuring its high reliability.
