Basic Shaft Alignment Tutorials
2165.1 Reverse Indicator Method
The major topics of this tutorial will discuss how to perform the Reverse Indicator method which is also called the Reverse Radial method or the Double Dial method, the advantages and disadvantages of this method, and how to construct alignment models in the side and top views from the shaft position measurements you obtain.
2165.2 Face-Rim Method
The major topics of this tutorial will discuss how to perform the Face and Rim method, the advantages and disadvantages of this method, and how to construct alignment models in the side and top views from the shaft position measurements you obtain.
2165.3 Mathematics for Single Unit Moves
The major topics of this tutorial will explain the mathematics to solve for single unit moves when using the Reverse Indicator or Face-Rim alignment methods. Single unit movement solutions will solve for the alignment correction moves needed to align one machine to the other machine. Since we are dealing with two element drive systems, like a motor and a pump, one set of equations will show you what moves you need to make to align the pump to the motor. Another set of equations will show you what moves you need to make to align the motor to the pump.
2165.4 Movement Boundary Conditions
The topics discussed in this tutorial will define what boundary conditions are, how to determine the movement restrictions in the vertical, lateral, and axial directions, and how to apply these movement restrictions to your side and top view alignment models to assist in determining the most effective movement solutions to bring your equipment into acceptable alignment tolerances.
2165.5 Correcting Misalignment
The topics in this tutorial will discuss the considerations when aligning machinery in the vertical, lateral and axial directions, suggestions on which moves you should make first, insuring that the shaft end to shaft end distance is properly attained, how to position your machinery in the vertical and lateral directions, and some suggestions when installing machinery for the very first time.
2165.6 Laser and Electronic Alignment Systems
The major topics of this tutorial will discuss the different electronic distance measuring devices that have, or could be, employed to measure shaft alignment possessing accuracies of one thousandths of an inch or better ... the basic operating principles of laser - detector systems ... the advantages and disadvantages of these systems along with suggestions for getting good results ... the mathematics used in laser alignment systems ... sign conventions for vertical offset, vertical angularity, horizontal offset, and horizontal angularity ... and how to construct alignment models from laser alignment system information.
