Maintenance
Before any maintenance or inspection is performed, refer to ANSI standard ANSI 2244.1-1952 for minimum safety
requirements covering lockout or tagout of energy sources for personal safety.
Practice good housekeeping. Keep the area around the conveyor and drive clean and free of obstacles to provide easy
access and to avoid interference with the function of the conveyor and drive.
Establish routine periodic inspections of the entire conveyor to insure continuous maximum operating performance.
To replace conveyor screw section, proceed as follows:
1)
Removal of a section, or sections, usually must proceed from the end opposite the drive. Make sure drive and
electrical power are disconnected before starting to disassemble.
2)
Remove the trough end, sections of screws, coupling shafts, and hangers until all sections have been removed, or
until the damaged or worn sections is reached and removed.
3)
To reassemble follow the above steps in reverse order.
4)
Quick Detachable conveyor screws can be removed at intermediate locations without first removing adjacent
sections.
Replacement parts can be identified from a copy of the original packing list, invoice, or drawing.
The coupling bolt lock nut may become damaged when removed. It is recommended practice to replace them rather than
re-use them when changing conveyor screw sections.
Periodic inspections should be made of the following:
1)
Trough. Check for wear and alignment. Tighten all bolts.
2)
Shafts. Check for wear. Check for bolt hole elongation and wear.
3)
Flights. Check edges for wear or damage.
4)
Bolts and nuts. Check all for wear and tightness.
5)
Seals. Check for leakage, adjustment, and wear.
6)
Guards. Check for oil level (if applicable). Check nuts and bolts for tightness.
7) Bearings. Check for lubrication. Refer to specific instructions as various types of bearings require varying
frequency of lubrication and varying types of lubrication. The following types of bearing materials may or may not
require lubrication.
Babbitt
Hard iron
Oil impregnated wood
Bronze
Nylon
Hard surfaced bearings
Teflon
