Shaft parts are indispensable in industrial applications, playing crucial roles in:
1. Power Transmission: Shafts transmit power from the source (e.g., motor) to the working components (e.g., gears, pulleys) of equipment. This ensures smooth and efficient power transfer within the mechanical system.
2. Torque Bearing: During operation, shafts must withstand significant torque. Precise design, strict dimensional control, and careful material selection are essential to ensure the shaft can handle high torque loads and maintain stable equipment operation.
3. Equipment Support: Shafts provide critical support for various equipment components. For instance, the crankshaft in an internal combustion engine supports the pistons and connecting rods, enabling the engine's smooth functioning.
Customer Inspecting Requirements for Shaft Parts
Dimensional Accuracy:
1. Support Journals: Critical for shaft fixation and support, these surfaces require high dimensional accuracy, typically within 0.01-0.03mm.
2. Matching Journals: Used to interface with transmission components (e.g., gears, pulleys), these have slightly less stringent dimensional accuracy requirements.
Shape Accuracy:
1. Key Surfaces: Including journals, external conical surfaces, and tapered holes, must exhibit minimal form errors (roundness, cylindricity).
2. Tolerance: Shape errors are generally confined within the specified dimensional tolerances.
3. Precision Shafts: Require separate geometric shape accuracy specifications on the part drawing.
Positional Accuracy:
1. Coaxiality: Precise alignment between inner and outer surfaces, and between critical shaft surfaces, is crucial.
2. Radial Runout: The deviation of a circular surface from its true center, particularly important for mating shaft sections.
a. Typical: 0.01-0.03mm for ordinary precision shafts.
b. High-Precision: 0.001mm or tighter.
3. Perpendicularity/Parallelism: End faces must be accurately perpendicular to the axis and parallel to each other, ensuring proper assembly and function.
