Calgary Alberta Canada T3C 0J7 ABSTRACT A new technique for shaft alignment is easy to apply for verification of alignment and can save users 10 000 to 20 000 in equipment costs. It is called the Reverse-Face Alignment technique. Examples are given with photographs for different styles of couplings such as gear elastomeric and flex-pack types. Alignment acceptability is determined immediately without complex geometrical calculations as necessary with other methods. The alignment measurement equipment not only is inexpensive but can be installed quickly for quasi-hot alignment checks. Remote readout and computer connection are possible but these complications are not perceived as being a benefit in most cases. Pitfalls are discussed for this and other methods for comparison purposes. 1. INTRODUCTION Shaft alignment can be measured and corrected in many ways. The goal is to cost-effectively and efficiently get a machine aligned and back running. The capital cost of the tools should be weighed against the total time required to do the alignment. Much of the time required to do an alignment is taken up by tasks not directly related to the measurement of misalignment. Therefore acceleration of a portion of the alignment task through large capital expenditure may be marginally beneficial. In some cases a tool to quickly check the state of alignment is all that is required. What is the alignment and is the alignment within guideline In other cases the alignment may be expected and found to be good but for trending purposes it is desirable to document the current alignment on an ongoing basis. Slow changes in alignment can indicate changes in foundations that require correction in the long term. by a laser alignment iconoclast. There are many reasons why dial indicators are a viable option to measure alignment. The capital cost outlay for a laser system versus a set of dial indicators and magnetic .
