Over-sizing the drive system when selecting and replacing worn v-belt drives is one simple, commonly-made mistake that actually causes premature wear on every component in a rotating system.
How can this be? Aren’t more belts always better? Not always with v-belt drive systems.
With the high cost of parts, labor and downtime, sizing belt drives correctly will save in many ways. If you are responsible for keeping your HVAC systems up and running, it’s important to understand why bigger is not always better.
Here’s a typical situation that occurs with many belt-drive systems: Read the rest of this entry »

Vibration analysis, with proper mechanical inspections, can make the difference between making the same ineffective repairs over and over again, or determining the precise nature of a problem and applying the proper solution once. Read the rest of this entry »

“We replaced the bearings three times and it still makes noise”…Sound Familiar?
If you are responsible for the reliability of HVAC air handling equipment, you probably have units that rumble and make more noise than they should.
Most often this is due to the shaft to bearing fit up. Improper bearing installation can cause the bearing’s inner ring to wear a groove into the shaft.
Once the shaft is grooved it’s only a matter of time before you realize that repeated bearing changes is not the solution. You also know that shaft replacement is difficult and very expensive.

Improper gear assembly can have disastrous results from the smallest of mechanisms to the most enormous. When one thinks of gear assembly, a few things may come to mind. From handed clocks and automobiles to helicopters and roller coasters, gears play an integral role in each machine’s function. With gears being so important, it is apparent that improper assembly of such gears could result in the need to replace a favorite family heirloom or be the biggest tragedy imaginable, costing people their lives.
A gear is a part in a mechanism or transmission that works with its similar part or parts in order to transmit activity from one part to another to determine direction and/or power while performing a specific role. In nonprofessional terms, it means the gears make the machine go. When all these gears are working properly the result is a finely-tuned piece of machinery that will efficiently perform the task for which it is designed. When gears are not properly assembled the results can be devastating. For example Read the rest of this entry »

These days machines are more efficient and run more smoothly and quietly than ever before. Companies such as HI-TEK Balancing Inc. know why that is. The precision balancing for machinery is not only helpful to the effectiveness of the machinery flawlessly performing the job it was designed for, but it is vital for the safety and longevity of the machine.
HI-TEK Balancing, identifies unbalance by recognizing the distribution of mass (the dynamic) in relation to force and vibration, then minimizing force and vibration to result in correcting the unbalance. In other words “dynamic balancing.” This is achieved by either adding or removing weight from the rotating component.
Dynamic Balancing is used to lessen the effects of centrifugal force, therefore reducing vibration and minimizing the damage that is done to the rotation devices. This not only extends the life of the machine, but makes the machine easier and more comfortable to use. An example of the sort of intensity of centrifugal force is to think about an amusement park ride such as the spinning cylinder, also known as the gravity ride, where the individuals in it stand up with their backs to the wall while the ride spins at high speed. The force that people feel pushing them against the wall of the ride is centrifugal force. Read the rest of this entry »
