Mechanically Controlled Linear Drive Enables Different Speed in Each Travel Direction

Amacoil/Uhing has announced a linear speed control option for Model RG rolling ring linear drives. Normally, the drive moves on a driven shaft with linear speed being adjustable via a pitch control lever located on the drive unit. Now, for applications that do not require variable speed, the new option lets users fix a specific linear travel speed in one or both directions of travel. The fixed travel speed is achieved using set screws which Amacoil inserts into the drive housing. No adjustments to motor speed or controls are necessary.

On a standard Uhing RG drive, the linear speed is adjustable, independently of motor speed, using the pitch control lever on the drive unit. When the set screw option is used, extra-long hex head screws are inserted into one end of the drive unit. The end of the screw protruding into the drive unit contacts the rolling ring bearing assembly and holds it at a specific angle relative to the shaft. This gives the drive a fixed linear speed in one direction.
