Hollow shaft wholesale

    Typical process

    Aluminum alloy tube fine drawing-cutting-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.

    The hollow shaft occupies a relatively large volume, but it can reduce the weight.

    According to the analysis of material mechanics, when the rotating shaft transmits torque, from the radial cross section, the more the outer place transmits the effective torque, the greater the effect. When the rotating shaft needs to transmit a large torque, a thicker shaft diameter is required. However, since the torque transmission at the shaft center is relatively small, a hollow one is generally used to reduce the weight of the shaft.

    The benefits of using hollow shafts for mechanical equipment

    We know that some mechanical equipment must use hollow shafts, so the use of hollow shafts has What are the benefits:

    1. Reduce the structural weight; such as the use of automatic vehicles

    2. Oil supply through the shaft bore , Air or water; such as engine pipeline:

    3. Place parts for manipulation or adjustment equipment in the shaft bore; such as a robot arm:

    4. Feeding through the shaft inner hole; such as automatic lathe:

    The appearance and use of hollow shafts make the performance and use of mechanical equipment There is more room for development.
