Geroler Sets For Orbital Hydraulic Motor

What materials are used for the stator and rotor pairs in orbital hydraulic motors and fully hydraulic steering systems, and how do these materials affect product quality and performance?

The stator and rotor pairs are the core components of orbital hydraulic motors and fully hydraulic steering systems.

Many people don't understand why a motor or steering system can have such a large difference in lifespan or performance.

Let's focus on the core components, and you'll understand why seemingly similar products can have such significant differences in performance and lifespan.

First, let's look at the materials.

Materials are the most fundamental condition for a component's performance. If the materials don't meet your requirements, no matter how much you optimize other aspects, the product's lifespan and performance will not meet expectations. For example, consider the application of stator and rotor pairs in fully hydraulic steering systems. Because fully hydraulic steering systems don't need to withstand excessive loads, in a highly competitive market, some manufacturers use powder metallurgy materials to manufacture the stator and rotor pairs to reduce costs. The raw material and processing costs of powder metallurgy are far lower than alloy steel; therefore, using this material will significantly reduce the product's raw material costs.

So, what are the main differences between this material and alloy steel? Powder metallurgy involves pressing metal powder into shape and then processing it through multiple steps. This material has significantly lower strength, hardness, and wear resistance compared to alloy steel. Furthermore, due to the different processing techniques, powder metallurgy is manufactured using molds, resulting in much lower precision.

Therefore, when this material is used in stator-rotor pairs and applied to fully hydraulic steering systems, it has a substantial impact on the performance and lifespan of the steering system. Consider this: if you use this type of steering system on large equipment, can the powder metallurgy pair withstand the increased system pressure? With increased usage frequency, the powder metallurgy pair may wear out rapidly, leading to steering mechanism failure and a significantly reduced product lifespan. The answer is undoubtedly yes.

Therefore, the selection of stator-rotor pair materials is paramount.

Secondly, the processing technology is crucial. Powder metallurgy and alloy steel require completely different processing methods. As mentioned above, powder metallurgy requires mold pressing, while alloy steel requires precision machining equipment for cutting and grinding. Therefore, the difference in machining precision between the two will be significant, as will the stability of that precision.

Thus, the choice of materials for the stator and rotor assembly directly affects the overall performance and lifespan of the orbital hydraulic motor or fully hydraulic steering gear. Therefore, when purchasing, it is crucial to understand the materials used for the core components of the motor. If the motor price is very low, be wary that the factory may have substituted powder metallurgy for the stator and rotor assembly.
