Abstract

The arrangement, shown in Figs. 1a and 1b, consists of a lead-screw drive which includes two screws driven by one common frameless DC servo drive motor mounted inside of a three-section slide assembly. The sections are: stationary outside housing, intermittent slide and internal slide. The lead screw 10 has a small diameter. It is fastened to the outside housing 12 and is non-rotating. The DC servo motor 14 is mounted to the intermittent slide 16. The nut 18 of lead screw 10 is attached to the left side of the hollow motor 14 armature. Lead screw 20 is attached to the right side of the motor armature. Lead screw 20 is of tubular design with the inside diameter large enough to allow lead screw 10 to pass through. The nut 22 of lead screw 20 is stationary and is attached to the internal slide 24.

Telescoping Slide and Drive Assembly

The arrangement, shown in Figs. 1a and 1b, consists of a lead-screw drive which includes two screws driven by one common frameless DC servo drive motor mounted inside of a three-section slide assembly. The sections are: stationary outside housing, intermittent slide and internal slide. The lead screw 10 has a small diameter. It is fastened to the outside housing 12 and is non- rotating. The DC servo motor 14 is mounted to the intermittent slide 16. The nut 18 of lead screw 10 is attached to the left side of the hollow motor 14 armature. Lead screw 20 is attached to the right side of the motor armature. Lead screw 20 is of tubular design with the inside diameter large enough to allow lead screw 10 to pass through. The nut 22 of lead screw 20 is stationary and is attached to the internal slide 24. The thread is right handed on lead screw 10 and left handed on lead screw 20. Lead dimensions of both screws are equal. The device operates in the following manner: The motor 14 rotates screw nut 18 about the stationary screw 10, causing the intermittent slide 16 to extend out of the outside housing
12. Since screw 20 is also attached to the drive motor 14, it rotates at the same time, advancing the internal slide 24 out of the intermittent slide 16 an equal amount. Therefore, 1.0 inch of travel of the intermittent slide 16 will also result in
1.0 inch of travel of the internal slide 24 for a total of 2.0 inches in relation to the fixe...
