Additionally, to obtain high performance in measuring angular positions, most commercial encoders must be adapted to expensive antibacklash gear-reduction systems; even so, when gears wear out, they begin presenting small measurement errors.
A bipolar stepper motor is mounted on a solid structure after which an antibacklash gear-reduction system reduces the movement with a ratio of 311.85748 : 1.
The Z axes servos incorporate antibacklash
systems for positioning accuracies [l+ or -] 0.025 mm, the company says.
The series of antibacklash
nuts eliminates the minimal backlash between the lead screw and nut interface on external linear actuators.
I was able to improve the responsiveness by adjusting the NexStar's antibacklash
feature (which jolts the declination motor at high speed for a moment whenever you switch guiding directions).
The LC router features ball screws and antibacklash
nuts on all three axes, offering smooth motion, a high level of accuracy and repeatability, and minimal maintenance needs.
HSI has added an AntiBacklash
Nut option to its line of linear motion products.
micrometer dial and locking thumb screw to adjust the zero setting; adjustable antibacklash
take-up nut; alternate drive and hand-crank position; and eight mounting or compounding bolts.
The resulting compact package delivers the reliability of a stepper with the added precision and repeatability of an antibacklash
system at a low price.
Machine features a fixed working surface, with the grinding-wheel spindle fed to the workpiece on a precision-ground ballscrew with an antibacklash
