 Worm Gear Screw Jacks

Worm Gear Screw Jack 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 The Thomson Screw Jack Range The Thomson MULI® and JUMBO® series worm gear screw jacks provide reliability in use and versatility in application. With its easy-to-mount, cubic housing, it can easily be extended to form wide-area jack systems with the help of its wide range of accessories. Thomson screw jacks are designed around a precision trapezoidal or ball screw drive engineered from Thomson for high accuracy and performance. • he large product range offers a variety of worm gear screw jack designs and sizes. Heavy loads can be T handled and high speeds can be...

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

 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.

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...

 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 con eniently lubricated at one v point. Maintenance – whether manual or automatic – is easy. Housing Material The housing in aluminium (Muli® 0...

General Technical Data The range includes a total of 11 worm gear screw jack models in two series: MULI® 0 to MULI® 5 with lifting capacities up to 100 kN and JUMBO® 1 to JUMBO® 5 with lifting capacities from 150 kN to 500 kN statically. Speed of travel - gear ratio H (high speed) Worm gear screw jacks with trapezoidal screw produce an advance of 1 mm for each revolution of the worm shaft. The linear speed is 1500 mm per min at 1500 RPM. Worm gear screw jacks with ball screws achieve between 1071 mm per min and 2124 mm per min, depending on size and lead. Speed of travel - gear ratio L (low...

 Worm Gear Screw Jacks General Technical Data Stop collar A Prevents the screw from being removed from the jack gearbox. Fitted as standard on ball screw versions N and V. Optionally available for screw jacks with trapezoidal screws. The stop collar cannot be used as a fixed stop. Self-locking The self-locking function depends on a variety of parameters: • Large pitches • Different gear ratios • Lubrication • Friction parameters • Ambient influences, such as high or low temperatures, vibrations, etc. • The mounting position Special versions In addition to the extensive standard range,...
