Industrial Robot Motor Shaft

The Industrial robot motor shaft by Guanshuo supplier adopts a shaft body structure optimized by finite element design, with a torsional stiffness of ≥200N·m/°. There is no obvious deformation under high speed and high load, which is suitable for the procurement performance requirements of high-speed movement and precise start and stop of the robot. The mating surfaces are treated with ion nitriding, hard chromium plating or DLC coating, with a surface roughness of Ra0.025-0.1μm, a friction coefficient of ≤0.1, and can withstand fatigue wear of over a million times, meeting the procurement standards for long-term operation of robots. Hollow shafts and lightweight alloy designs can be adopted. The precision of the splines, flat keys and conical surface connection sections of the shaft body reaches the precision level, which is suitable for seamless direct connection of robot harmonic reducers and RV reducers, meeting the procurement requirements of customized assembly.

Comparing the advantages of the ordinary motor shaft

The high-frequency operation, precise positioning and continuous production requirements of industrial robots cannot be met by ordinary motor shafts. Guanshuo Precision Industrial Robot Motor Shafts possess numerous advantages that precisely fill the gaps of ordinary motor shafts, completely addressing the core concerns of robot procurement and meeting the strict demands of automated production lines.

The fatigue resistance and durability are far superior to those of the ordinary models, eliminating frequent malfunctions.

Under normal circumstances, the shafts of ordinary motors are prone to fatigue wear when operating at high frequencies and under repeated loads. It won't take long before they break or malfunction, requiring frequent shutdowns for replacement, which seriously affects production efficiency. However, the Ganshuo industrial robot motor shafts, after undergoing special processing, can easily withstand millions of cycles of fatigue wear without any faults. This completely eliminates the concerns about the motor shafts being prone to fatigue breakage and the need for frequent maintenance during high-frequency operation when purchasing. They are fully compatible with the continuous production requirements of automated production lines and no longer need to worry about frequent replacements and maintenance.

The structure is more optimized, more rigid, and shows no obvious deformation.

The shafts of ordinary motors do not have targeted structural designs. Under high-speed and high-load conditions, they are prone to significant deformation, which leads to deviations in equipment operation and a decline in accuracy. This Industrial robot motor shaft adopts an optimized shaft structure designed through finite element analysis. Its torsional stiffness is ≥ 200 Newton-meters/degree. Even under the strict conditions of high-speed movement and precise start-stop of the robot, it will not undergo significant deformation and can always maintain a stable operating state. This is a rigidity standard that ordinary motor shafts simply cannot achieve.

Higher precision, suitable for precise positioning and seamless assembly of robots

The precision of ordinary motor shafts is relatively low, and the mating surfaces are rough, which cannot meet the requirements for precise positioning and seamless assembly of industrial robots. After assembly, it is prone to jamming and deviation, affecting the operational accuracy of the robot. However, the motor shafts of Guanshu industrial robots have mating surfaces that have been treated with ion nitriding, hard chrome plating, or DLC coating, with a surface roughness as low as Ra0.025-0.1 micrometers. The diameter runout is controlled within ≤0.002-0.005 millimeters, and the outer diameter tolerance reaches the h6 standard. They can achieve micrometer-level precision, which is the core guarantee for precise positioning of robots. At the same time, the spline, flat key, and conical surface connection parts of the shaft body have reached the standard of precision, and can be directly connected with the robot's harmonic reducer or RV reducer without any gap, meeting the customized assembly requirements. Ordinary motor shafts simply cannot achieve such high-precision assembly compatibility.

Superior weather resistance, suitable for stable operation in various scenarios

The temperature resistance and stability of ordinary motor shafts are relatively poor. When switching between different temperature zones in industrial workshops, or operating under long-term high or low temperature conditions, they are prone to problems such as size changes and coating peeling, which affect their service life and operational stability. The working temperature range of industrial robot motor shafts is from 40℃ to 120℃. After undergoing professional heat treatment to eliminate internal stresses, they will not experience size changes or coating peeling under high or low temperature conditions. They can meet the weather resistance requirements of multiple temperature zones in industrial workshops, meet the continuous operation needs, and have much better adaptability than ordinary motor shafts.

More flexible design, meeting the lightweight requirements of robots

The shafts of ordinary motors are mostly of a single solid structure, which are heavy and cannot meet the requirements of lightweight and efficient operation of industrial robots. However, the shafts of Guanshu industrial robot motors can adopt hollow shafts and lightweight alloy designs. While ensuring rigidity and accuracy, they can effectively reduce the weight of the shafts, meet the requirements of lightweight design of robots, and improve the operation efficiency of robots. These are design advantages that ordinary motor shafts do not have.
