Why Don’t I Input a Coupling Diameter?
We often get asked why we don’t input a coupling diameter when performing a precision shaft alignment with the ACOEM laser alignment systems. The coupling diameter (or more correctly sweep of a face dial indicator) is only required when doing a rim and face dial indicator alignment or when the user wants to know the…Read More
Alignment Considerations of Machines with Stiff Elastomeric Couplings
These types of couplings are quite common in industry, and there are various companies producing similar types of couplings. They are capable of transmitting large amounts of torque in a reasonably small space. They also do not require lubrication, and are quite easy to install, in most circumstances. These attributes make them quite desirable in…Read More
Base Bound Machinery Corrections
Most aligners are familiar with a bolt bound situation, which occurs when the motor cannot be moved enough to achieve proper horizontal alignment. A base bound condition occurs when a motor cannot be lowered sufficiently to achieve proper vertical alignment. Here is an example. During a customer’s recent pump replacement, the motor was left in…Read More
Fudging Your Shims? Go The Same Direction.
When performing a precision laser shaft alignment, it is best to add or remove shims exactly as the display unit indicates. There are circumstances when this may not be possible due to your assortment of shims, or when you want to “fudge” your shims slightly to keep the total number of shims low. (Clink for…Read More
Alignment and Vibration: What is the correlation?
This is a subject that comes up relatively frequently with our customers and observations from the field. The purpose of today’s blog post is to illustrate what can and often does happen. While misalignment can and does present with easily identifiable vibration signals; often it does not. Misalignment may be present in a machine, developing…Read More
Low Cost Thermal Diagnoses Misalignment Machinery Health
With the availability and decreasing prices of technology to help diagnose rotating machinery health, machine failure should be a diminishing concern. Thermal imaging cameras can be expensive; however, these cameras have very detailed diagnostic abilities and high resolution. Reduced cost Thermal Imaging has recently become available through various sources. I recently purchased an infrared camera…Read More
