Technical Tips
Ordering EasyLock is harder than it should be
EasyLock assures that there is no play between a rotating shaft and a core or reel placed on the shaft. So in converting and packaging applications where there can be long cores of sheeted and rolled material rotating at high speeds, using EasyLock is...
Is this you?
It's taken me 10 years to become somewhat proficient at being able to match Uhing linear drives to applications for which they will be an ideal fit. I'm no genius. But every day I speak with folks who seem to think they are. If someone asked me what is...
Are you changing the length of travel on your Uhing traverse drive?
If you are, then depending on how you are changing travel length, you need to be aware of shaft vibration or you might run into some problems. In the photo below, the traverse assembly was built for a maximum travel of 28 inches.
The numbers game
When you phone or email Amacoil regarding your Uhing traverse drive unit, there are a number of different ways to identify the unit. The model number on the little metal name tag is the most basic. The model number is a generic number that tells us the...
It doesn’t always make “sensor”
This here is a pretty cool picture of a Uhing traverse winding set up to which sensors and electronics have been added. In this case, the sensors monitor traverse linear speed, spool rotational speed and line feed speed.
Easy Fixes — maybe
Recently, a customer went to the trouble of shipping his Uhing traverse drive unit to Amacoil. The drive arrived yesterday and when I phoned the customer to ask him what the trouble was he said, "It's no good."
Using adjustable pitch to an advantage
Today we completed a Uhing assembly with the "S" option. This option enables the Uhing traverse to move at a set pitch in one direction, and then at the same or a different set pitch after reversal. In this case, the customer needed the drive to move...
Repairs to Uhing rolling ring drives
I get calls all the time from folks who want to repair their Uhing traverse drive. They want a parts list and they want to order the parts and do the repairs at their facility. Regardless of mechanical aptitude, repairing a Uhing drive is tricky. There...
It’s a friction drive
That means that the bearings put a significant "bite" on the shaft. Anything you do in your set up to interfere with that "bite" will cause problems for you. You can't lessen or increase the pressure of the bearings against the shaft. If you use oil or...
Do you need to fine tune your winding traverse stroke length to improve spooling accuracy
As an alternative to the standard manually adjustable end stops on Amacoil-Uhing traverse drives, an option is now available for fine adjustment of traverse travel distance. The option enables users to meet level winding application requirements where...
