Mechanical Training: Alignment and Couplings

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.
