Some of the key parts of screw jacks are trapezoidal lifting screw, worm gear, worm screw
and gear housing.
The locking mechanism of the design is a worm screw
, allowing the Y axis movement to be easily adjusted by the user should they need to adjust the height of the arm rest.
Designed for heavy-duty subsea applications, the Rotork WGS quarter-turn gearbox features a worm shaft supported on tapered roller bearings, a high-strength alloy steel worm screw
, and a membrane- or piston- type pressure compensator to enable operation at any depth.
"He designed the helicopter and many other machines such as the eccentric cam, the worm screw
, the hygrometer, the oil press, the anemometer, the rolling mill, the flywheel, the jack or the toothed rack, the ball bearings amongst others," he said.
The new product features heavy-duty construction and integrates the casting material with a ground carbide worm screw
mechanism, which helps in creating a balanced environment for rigid machining.
A PRECISION machined worm screw
jack from Thomson has been designed to provide powerful lifting and positioning where space is at a premium.
Obviously the telescope should not be assembled out of balance, especially with the RA axis locked, as this will damage the worm screw
and strip the wheel teeth.
The 5AX-20011 CNC Rotary Table has a patented carbide worm system that uses a carbide worm screw
and ion nitrided worm wheel, rather than a conventional bronze or bronze alloy actuation mechanism.
Designed with a carbide worm system, the table has reduced friction due to the incorporated carbide worm screw
and an ion-nitrided worm wheel, the company says.
