Hydraulic Driven Motor Shaft

The Hydraulic driven motor shaft produced by Guanshuo manufacturer is an exclusive adapter component for hydraulic pumps, hydraulic controllers, and hydraulic motors. It is specifically designed in terms of both process and structure, perfectly matching the high-pressure and multi-media working conditions of the hydraulic system. The shaft body undergoes quenching and tempering treatment, and is further combined with surface quenching or carburizing and nitriding processes. This not only ensures an extremely high hardness on the surface but also retains the core high toughness, enabling it to easily withstand the instantaneous high-pressure impact and alternating loads in the hydraulic system, preventing deformation or fracture of the shaft body, and meeting the strict requirements of high-pressure start and stop for hydraulic equipment.

Due to the particularity of the hydraulic oil medium, we have specially designed anti-corrosion and wear-resistant structures to fundamentally solve the problems of common motor shafts getting rusty and the coating peeling off, avoiding the contamination of the hydraulic oil by rust marks and coating fragments, and ensuring the clean and stable operation of the hydraulic system. At the same time, the sealing connection sections and shoulder positioning of the shaft body have all been finely processed to meet the high-pressure sealing and assembly requirements of the hydraulic system. Whether it is direct connection or flange-type concentric assembly, they can be seamlessly adapted.

Product Advantages

Unlike ordinary motor shafts, each advantage of our Hydraulic-driven Motor Shaft precisely addresses the purchasing pain points in the hydraulic application scenario. It doesn't engage in empty talk; instead, it truly helps the purchasers save time, money, and improve efficiency.

Resistant to impact and not prone to damage, addressing the core pain points. During the operation of the hydraulic system, the high-pressure impact and alternating loads can easily cause deformation or fracture of the ordinary motor shaft. However, our motor shaft surface hardness can reach HRC58-62, with core toughness ≥ 90J/cm². The extended part of the shaft is also hardened through high-frequency quenching, achieving a hardness of HRC45-55. The hardened hardened zone depth is 1.5-3.0 millimeters, which can stably withstand high-pressure impact, prevent deformation and fracture, significantly extend the service life, and reduce the frequency of replacement.

Prevent corrosion and protect the oil, ensuring system stability. Specifically designed for hydraulic oil medium, the sealing surfaces and mating surfaces have undergone mirror polishing and hard coating treatment. This not only resists wear and adhesion, but also effectively prevents corrosion, avoiding rusting of the shaft and peeling of the coating, preventing contamination of the hydraulic oil. It eliminates the need for frequent replacement of hydraulic oil and seals, reducing maintenance costs and ensuring the long-term clean and stable operation of the hydraulic system.

The precision meets the standard, the assembly is smooth, and the efficiency is enhanced. The mating section of the shaft seal has a tolerance of IT5 level, with a surface roughness of Ra0.05-0.2 μm, a roundness and cylindricity of ≤ 0.003 mm, an outer diameter tolerance of h7/h6, and a shaft shoulder positioning accuracy of ≤ 0.008 mm. It can seamlessly cooperate with hydraulic oil seals and combined sealing rings. During assembly, there is no need for repeated adjustments, significantly improving the assembly efficiency. At the same time, it meets the assembly standards for high-pressure sealing in hydraulic systems.

Flexible customization, wide adaptability, and capable of meeting diverse needs. The extended part at the shaft end can be customized with various structures such as flat keys, spline keys, and conical surfaces, which can be used to connect various hydraulic equipment like hydraulic pumps, hydraulic motors, and hydraulic reducers. Whether it's standard specifications or customized requirements, it can be precisely matched without having to accommodate general models.

Product features

Focusing on the core requirements of hydraulic drive scenarios, our motor shafts have been meticulously designed in detail. Every feature is tailored to the actual usage scenarios, balancing performance, practicality and convenience.

1.Combining strength and durability, with outstanding resistance: The surface is extremely hard, the core is highly resilient. After multiple quenching treatments, the tempering hardness reaches HB260-300. It can withstand high-pressure impacts and alternating loads, and is not prone to brittle fracture, making it suitable for the working conditions of hydraulic systems such as high-pressure start-stop and frequent operation.

2.Precise processing, excellent sealing performance: The sealing fitting section and the mating surfaces have undergone precise processing and mirror polishing. The friction coefficient is ≤ 0.12. Not only is the assembly smooth, but it also effectively reduces friction loss, avoiding frictional faults with sealing components and hydraulic elements, and meeting the low-loss requirements of hydraulic transmission.

3.Anti-corrosion design, easy maintenance: Special anti-corrosion and wear-resistant structures are adopted to prevent oil contamination. Moreover, the product itself is easy to maintain. Daily maintenance only requires a simple inspection of surface wear and sealing conditions, without the need for complex operations, thereby reducing maintenance difficulty and costs.

4. Detailed and thoughtful, highly adaptable: The chamfering design is C1-C2, which takes into account both assembly safety and convenience; the shoulder positioning accuracy is high, suitable for various assembly methods, with flexible customization, and can meet the customized procurement requirements of different hydraulic drive systems.

FAQ

The following are the most frequently asked questions by customers when purchasing and using hydraulic-driven motor shafts. The explanations are straightforward and easy to understand, without using excessive technical jargon, helping you quickly clarify your concerns and grasp the key points of usage.

Q1: Can this motor shaft be used for all hydraulic equipment?

A: It is compatible with the majority of mainstream hydraulic equipment. The core components it adapts to include hydraulic pumps, hydraulic motors, and hydraulic reducers. Whether it is a direct connection or a flange-type coaxial assembly, it can meet the requirements. Moreover, the extended part at the shaft end can be customized with structures such as flat keys, spline keys, or conical surfaces. As long as you provide the specific equipment specifications and assembly requirements, we can precisely match it. There is no need to worry about the problem of milestone compatibility.

Q2: Can it really prevent the contamination of hydraulic oil?

A: Sure, this is the core feature we have specially designed for the hydraulic application. We have treated the shaft body with anti-corrosion and wear-resistant structures, and also applied hard coatings to the sealing surfaces and mating surfaces. This can effectively prevent the shaft body from rusting and the coating from peeling off, avoiding rust marks and coating fragments from being mixed into the hydraulic oil. This way, we can ensure the cleanliness of the hydraulic oil from the very beginning, reducing the frequency of oil replacement and equipment failures.

Q3: In the event of a high-pressure impact from the hydraulic system, won't it actually deform or break?

A: Don't worry at all. The shaft has undergone multiple processing techniques such as quenching and tempering, surface quenching or carburizing and nitriding. The surface hardness can reach HRC 58-62, and the core toughness is also sufficient. It can withstand instantaneous high-pressure impacts and alternating loads. Moreover, the depth of the quenched hardened area is adequate. Even if the hydraulic equipment undergoes high-pressure start-stop or frequent operation, there will be no deformation or fracture, ensuring durability.
