Abstract
A single drive positioning system includes a drive shaft, a motor, a first worm screw, and a second worm screw. The motor has a motor output connected to the drive shaft and operable to selectively rotate the drive shaft. The first worm screw is mounted on the drive shaft for rotation therewith. The second worm screw is mounted on the drive shaft for rotation therewith.
Claims21
A single drive positioning system comprising:
- a drive shaft;
- a motor having a motor output connected to the drive shaft and operable to selectively rotate the drive shaft;
- a first worm screw mounted on the drive shaft for rotation therewith;
- and
- a second worm screw mounted on the drive shaft for rotation therewith.
2 more elements
A method for positioning an object, the method comprising:
- providing a single drive positioning system comprising:
- a drive shaft;
- a motor having a motor output connected to the drive shaft and operable to selectively rotate the drive shaft;
- a first worm screw mounted on the drive shaft for rotation therewith;
- and
- a second worm screw mounted on the drive shaft for rotation therewith;
- and
- operating the motor to rotate the drive shaft.
5 more elements
A single drive positioning system comprising:
- a drive shaft;
- a motor having a motor output connected to the drive shaft and operable to selectively rotate the drive shaft in each of a clockwise direction and a counterclockwise direction;
- a first worm drive including:
- a first worm screw mounted on the drive shaft for rotation therewith;
- and
- a first worm wheel intermeshed with the first worm screw;
- a second worm drive including:
- a second worm screw mounted on the drive shaft for rotation therewith;
- and
- a second worm wheel intermeshed with the second worm screw;
- a first overrunning clutch between the drive shaft and the first worm screw, wherein the first overrunning clutch is configured to drive the first worm screw in the clockwise direction when the drive shaft is driven in the clockwise direction, and to permit the drive shaft to rotate independently of the first worm screw when the drive shaft is driven in the counterclockwise direction;
- and
- a second overrunning clutch between the drive shaft and the first worm screw, wherein the second overrunning clutch is configured to drive the second worm screw in the counterclockwise direction when the drive shaft is driven in the counterclockwise direction, and to permit the drive shaft to rotate independently of the second worm screw when the drive shaft is driven in the clockwise direction.
10 more elements
A mass analysis system comprising:
- an inductively coupled plasma (ICP) torch;
- a sample introduction element including an inlet;
- and
- a single drive positioning system operable to selectively align the ICP torch with the inlet, wherein the single drive positioning system includes:
- a drive shaft;
- a motor having a motor output connected to the drive shaft and operable to selectively rotate the drive shaft;
- a first worm screw mounted on the drive shaft for rotation therewith;
- and
- a second worm screw mounted on the drive shaft for rotation therewith.
