Hydraulic Wheel Motor

 

Hydraulic wheel motors are an important component of hydraulic drive systems. These wheel motors are commonly used in heavy machinery, such as agricultural equipment, construction vehicles, and mining equipment. They are responsible for powering the wheels, allowing the machinery to move forward, backward, or turn.

 

Hydraulic wheel motors consist of a rotating mechanical assembly that is powered by hydraulic fluid. The hydraulic fluid is pressurized by a pump, which is also part of the hydraulic drive system. As the pressurized fluid enters the motor, it moves the mechanical assembly, which in turn drives the wheels.

 

One of the advantages of hydraulic wheel motors is their durability. They are designed to withstand harsh operating conditions, such as extreme temperatures, high pressure, and heavy loads. They are also low maintenance and have a long service life, making them a cost-effective option for heavy machinery.

 

Another advantage of hydraulic wheel motors is their precise control. The speed and direction of the wheels can be easily controlled by adjusting the flow of hydraulic fluid to the motor. This allows for smooth and accurate movement, which is important for tasks such as grading, excavating, and digging.

 

Hydraulic wheel motors are also energy-efficient. The hydraulic drive system allows for the transfer of energy from the pump to the motor with little energy loss. This means that less fuel is needed to power the machinery, resulting in lower operating costs and reduced emissions.

 

In addition, hydraulic wheel motors are versatile. They can be used in a variety of machinery, from small tractors to large excavators. They can also be customized to fit specific applications, such as different wheel sizes or torque requirements.

 

Overall, hydraulic wheel motors are essential components of hydraulic drive systems. They offer durability, precise control, energy efficiency, and versatility, making them a popular choice for heavy machinery. As technology continues to improve, hydraulic wheel motors are expected to become even more efficient and effective, further expanding their applications in various industries.

 

 

HQX2 series deceleration motor is a deceleration traveling motor independently developed by Jining Heqi according to the market requirements for traveling motors, and the motor consists of ZMS series motor and planetary reducer.

Since the motor is not equipped with a brake mechanism, the motor structure is more compact, and has the characteristics of small dimension, light mass, large torque, high efficiency, and low noise.

◎ The intermittent operating pressure refers to the Max. allowable operating pressure at the motor inlet port, and the continuous operating pressure refers to the pressure difference between the inlet port and the return port.

◎ Do not operate the motor at the Max. speed and the Max. pressure at the same time.

◎ The motor operating time per minute must not exceed 10% under intermittent operating conditions.

◎ Recommended oil: anti-wear hydraulic oil; Viscosity: 37-73cst; ​​Oil cleanliness: IS018/13; Max. operating oil temperature: 80 ℃.

◎ With special dynamic seal design, the Max. allowable back pressure of the motor can be up to 10MPa; however, in order to obtain the good service life and comprehensive mechanical performances, the back pressure should not exceed 5MPa. If it is exceeded, it is recommended to connect the external drain pipe; when connecting the external drain pipe, ensure that the motor is always filled with oil. The external drain pipe should be throttled at a certain degree, to maintain a back pressure of more than 3.5 Bar. When connecting the external drain pipe, in addition to maintaining a low back pressure, the wear contaminants generated inside the motor can be removed and a certain cooling effect can be achieved.

◎ There should be a running-in period before the motor is operated at full load. It is recommended to run for 1h at 30% of the Max. operating pressure.

 

 

Note: For port dimension, see ZMS series motor.
