Worm Gear Screw Jacks

Applications Worm gear screw jacks are ideal for various applications, regardless if you are lifting, lowering, tipping or moving. In each case, the different industries and the different power parameters require a powerful, reliable screw jack that is easy to adapt to the specific application, and to extend to a complete worm gear screw jack system.

Worm Gear Screw Jacks This printing press application utilizes two screw jacks to set the proper gauge on the feed rollers. The same type of solution can be used in many types of paper, plastic or sheet metal rolling applications. Solar Panels A double clevis screw jack supports the motion for solar panels such as this one. Screw jacks are sturdy and strong enough to manipulate large solar panels, satellite dishes and wind turbines even in extreme conditions and temperatures. Screw jacks will work relentlessly all year round requiring a minimum of maintenace.

Automated Guided Vehicles Screw jacks can be used to move and position loads on all types of vehicles. They can tilt cabins, hoods or hatches on mobile-off-highway vehicles and perform numerous other operations on construction, agriculture and marine/off-shore equipment. Lifting Aids In this automobile lift, the lifting motion is provided by two inverted rotating ball screw jacks. Screw jacks can also be used in other types of lifting devices such as work table height adjustment, scissor tables, platform adjustment and leveling applications.

Worm Gear Screw Jacks Applications Few industries place as much demand on a handling system as aircraft construction. The handling of large and heavy objects, like aircraft wings, the need for extreme accuracy and unyielding quality standards make for a difficult challenge. At Thomson, we have both the unique experience and the products to meet the precise needs of the most demanding material handling applications. Tilt Station Once the tilt station transport platform is correctly positioned in the tilt station, Thomson screw jacks tilt the wing and the platform 90 degrees. In this position,...

Worm Gear Screw Jacks Presentation of the MULI® and JUMBO® Series Thomson worm gear screw jacks of the MULI® and JUMBO® series are manufactured for loads from 2.5 to 500 kN. All models are designed for both pushing and pulling forces, and for position-independent functioning. The cubic housing, standardised mounting material and end-pieces, and pre-drilled flange holes permit the ideal installation of motor, gears and shaft encoder. Synchronisation of several worm gear screw jacks is simple with the complete range of accessories.

Worm Gear Screw Jack Selection Chart MULI®0 - 5 ( – 100 kN) Axially travelling screw The rotary motion of precision worm gearing (worm shaft and internally threaded worm wheel) is converted into axial linear motion of the screw, which travels through the gear box housing. The load is attached to the end of the screw. N/V-TGS N-KGS Rotating screw Driven by a precision worm gearing (screw keyed to the worm wheel), the rotary motion of the screw is translated into linear motion of the travelling nut on the screw.

Worm Gear Screw Jacks Worm Gear Screw Jack Selection Chart Version N Trapezoidal screw Rotation of the screw is prevented by its permanent attachment to the guided load. One full turn of the worm shaft leads to a stroke of one millimeter. For tough conditions, good price/performance ratio. Ball screw One full turn of the worm shaft leads to a stroke of 0.25 mm. For longer duty cycles, higher efficiency, high positioning accuracy. Version V Version V with antirotation device is recommended if the screw cannot be secured externally to prevent rotation.

Design Versions Axially travelling screw - version N or V The rotary motion of precision worm gearing (worm shaft and internally threaded worm wheel) is converted into axial linear motion of the screw, which travels through the gear box housing. The load is attached to the end of the screw. Functional Design The cubic housing with its pre-drilled flange holes offers simple mounting, and allows longer power-on times. Longer lubricant lifetimes are ensured, because heat is more efficiently dissipated. Lubrication of the Worm Wheel Radial lubrication holes in the worm wheel grease the trapezoidal...

Worm Gear Screw Jacks Design Versions Rotating screw - version R Driven by a precision worm gearing (worm shaft and worm wheel), the rotary motion of the screw is translated into linear motion of the travelling nut on the screw. Heavy Duty Bearings Radial deep-groove ball bearings (Muli® 0 – 3) and conical roller bearings (Muli® 4 + 5 and JUMBO® 1 – 5) on the worm shaft make it possible to handle heavy loads. Lubrication The worm gear screw jack is conveniently lubricated at one point. Maintenance – whether manual or automatic – is easy. Housing Material The housing in aluminium (Muli® 0 – 2)...
