Using adjustable pitch within an application

When a Uhing assembly has an “S” option incorporated, it 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. An example: Amacoil recently assisted a customer who needed the drive to move 0.4 inches when moving to the right, and 1.030 inches when moving to the left. The customer was unfamiliar with Uhing traverse drives, so the interaction with an Amacoil representative enabled the system to be configured to the required specifications.

It is important to note pertinent additional information pertaining to adjustable pitch capabilities. Each Uhing traverse has a maximum linear pitch. When the pitch control level is set at #10, this is the distance the drive will move on the shaft per one revolution of the shaft – regardless of shaft rotation speed. The pitch control lever enables the user to turn the pitch down over a 10:1 range. As an example, if the maximum pitch was 0.5 inch, the user can achieve a 0.05 inch pitch by turning the lever to #1. This pitch range of 0.5 to 0.05 inch will remain the same even if the spool shaft rotation speeds up or slows down.

An additional consideration is detailed and illustrated below. If the intent is to drive the Uhing shaft by linking it to the spool shaft via a timing pulley, you can shift the 10:1 pitch range up or down. For example, if the Uhing traverse has a maximum pitch of 0.5 inch, you can make the maximum pitch 1 inch by making the timing wheel on the spool shaft twice the size of the timing wheel on the Uhing shaft.
