Replacing the shaft on a pouch packaging machine is a step that matters. Done correctly, the machine runs smoothly. Done incorrectly, it affects overall performance.
Preparation
Measure first. Check the length, shaft diameter, keyway position, and step dimensions of both the original shaft and the new one, and confirm the new shaft matches the original. Inspect the new shaft for dents and rust, and check for burrs at the journals. Avoid striking the shaft ends during transport. Move it next to the machine and set it aside for replacement.
Installing the new shaft
Place the new shaft into the sliding seat and secure it with a hex wrench. Then fit the pin that supports the shaft. The shaft is only firmly fixed once the pin is in place. Tighten in a diagonal sequence in stages rather than all at once, so the shaft bearing does not load unevenly. We can machine replacement shafts to customer drawings, with material, heat treatment, and tolerance specified by the drawing, for single pieces or small batches.
Post-installation check
Check that the shaft is firmly fixed and turns without binding or abnormal noise. Then apply insulation treatment to keep the machine running correctly and reduce safety risks from excessive clearance. Run the machine without load first, and confirm nothing is abnormal before returning to production.
Beyond shaft components for packaging machines, our precision machining capability also covers non-standard parts for printing machinery, textile machinery, and woodworking machinery, as well as precision structural parts for medical devices and semiconductor equipment. Custom parts for yachts and RC race cars can also be machined to drawing. Hansheng Automation takes on single pieces or small batches, with material, tolerance, and surface finish specified by the drawing.
