Courtesy: AmacoilAll Uhing Model RG linear drives from Amacoil now feature a manual pitch control which permits a 10:1 adjustment of the linear pitch of the drive unit. Each of seventeen Model RG drive units has a specific maximum linear pitch. This is the linear distance the drive will move on the shaft per one revolution of the shaft. The pitch control lets users turn the pitch down in 0.01 increments across one hundred discrete settings.

In applications where it is desirable or necessary to keep the drive motor running at a constant speed, the adjustable pitch feature enables a variable speed drive system without requiring changes or adjustments to the drive motor speed. If greater linear speed changes are needed than are afforded by the pitch control, then the drive motor speed may be increased or decreased without affecting the linear pitch of the drive. Once the pitch of the drive is set, it will remain the same regardless of the drive motor speed. The pitch will change only if the operator adjusts the pitch control.

In applications where a specific linear pitch range is required, the traverse shaft may be driven via belt and pulley linkage to the main drive shaft. The ratio between the two pulleys establishes the desired linear pitch range. For example if the pulley on the traverse shaft is twice as large as the pulley on the main drive shaft then the drive will move two times its normal pitch per one shaft revolution.
