elaborate on the difference and application of hollow shaft and solid shaft
we use the optical shaft on industrial equipment, from the structure, you can use the optical shaft It is simply divided into hollow shaft and solid shaft. In the case of the same material and the same cross-sectional area, the hollow shaft has stronger torsion resistance than the solid shaft and can withstand larger external moments. Under the same external torque, the hollow shaft is less material than the solid shaft. This can also be seen from the stress distribution of the circular section. When the maximum shear stress on the circumference of the solid shaft is close to the allowable shear stress, the shear stress in the middle part is still far from the allowable shear stress, and most of the materials in the middle are not fully utilized. What it does. Chrome rods are also widely used.
But hollow shafts are more difficult to manufacture than solid shafts, and the cost is higher. Both of them are widely used in packaging machinery: filling machinery, filling machinery, wrapping machinery, Sealing machinery, labeling machinery, cleaning machinery, drying machinery, sterilization machinery, strapping machinery, container machinery, multi-functional packaging machinery, packaging material manufacturing machinery, packaging container manufacturing machinery, and auxiliary packaging machinery for completing other packaging operations. As for whether the hollow shaft or the solid shaft is more versatile, in actual work, it is necessary to analyze the specific conditions and choose the shape and size of the cross section reasonably.
Typical process
Aluminum alloy tube fine drawing-cut off-necking at both ends (some do not have this sequence)-inner wall Spraying heat-resistant black paint-annealing-cutting at both ends-punching waist holes at both ends-punching U holes and flanging-surface cutting.
Accuracy
The outer diameter dimension accuracy reaches 0.03mm, and the runout accuracy reaches 0.03mm.
