Study Notes

Courseware Sample

This document is a sample of courseware for a mechanical training system.
The course covers alignment and couplings.

Courseware Outline

The courseware includes job sheets and work orders.
Job sheets cover topics like the dial indicator method, reverse indicator method, flange couplings, flexible sleeve couplings, chain couplings, gear couplings, and grid couplings.
Work orders are also included and cover the same topics as the job sheets.
The courseware also features appendices with various charts and tables, including equipment utilization charts, components of alignment and coupling systems, unit conversion tables, safety procedures, lockout/tagout procedures, and start-up procedures.
Post-tests are also part of the courseware.

Job Sheet 2 (Reverse Indicator Method) Information

The reverse indicator method uses two dial indicators to measure parallel and angular shaft misalignment.
Measurements are taken on the coupling hub.
Vertical and horizontal measurements are made simultaneously.
This method is more accurate than using straightedge gauges or feeler gauges.
The method doesn't require disassembling the coupling.

Equipment Required for Job Sheet 2

Universal Base Assembly (model 46603)
Motor Package (model 46609)
Couplings (model 46610)
Pillow Block Bearings Panel (model 46611)
Alignment and Coupling Package (model 46615)
Test/Measurement Package (model 46630)
Tool Box Component Package (models 46631 and 46631-10)

Safety Procedures for Job Sheet 2

Safety glasses are required.
Safety shoes are required.
No loose clothing or jewelry should be worn.
Long hair should be tied back.
The work area should be clean and free of oil.
The floor should not be wet.

Work Order 2 (Reverse Indicator Method)

The work order details the steps to perform reverse indicator method shaft alignment.
Correct placement of indicator probes is crucial during measurements.
The procedure emphasizes the importance of proper rough alignment beforehand using alternative methods (e.g., straightedge/feeler gauge method).
Measurements must be carefully recorded, accounting for the polarity (sign) of readings.
This procedure requires careful attention to the equipment setup and recording of measurements, for accurate alignment.

Specific Instructions for Alignment

The procedure includes steps for properly installing couplings, tightening various fasteners, mounting and adjusting dial indicators, and measuring misalignment using specific formulas.
