Bevel Gear Screw Jack

Bevel Gear Machine Rotating Screw Jack offer higher efficiency and greater speed than other mechanical screw jacks

Bevel gear jacks use the same trapezoidal or acme screws used in machined screw jacks to move the load.

Lude’s Bevel Gear Jack, G Series, combines a Cubic Spiral Bevel Gearbox and Screw Jack resulting in a high speed, very accurate solution for lifting-lowering-pushing-pulling applications.

ACME worm screw jacks are widely used, they are suitable for heavy load and low speed, and they have self-lock function.

Cubic screw jack featuring a compact and versatile cubic housing.

Up and down at the same time , and rotate in the same section . Arrangement recommends no more than 400MM in one minute. If the connecting shaft is used in arrangement with more than 1.5 meters, it is recommended to use a Trunnion. It is suitable for industrial applications in a variety of industries, with a variety of combinations and flexible operation.

Ball screw jacks combine the gear unit with a linear drive performed by a ball screw that, in comparison with the traditional acme screw, offers following advantages: • higher total efficiency • longer life of the whole linear drive system The following two comparative examples give an idea of the higher efficiency that can be obtained with this system: • considering a screw jack consisting of a worm gear with linear drive performed by an acme screw,  the total efficiency of the screw jack is between 10 % and 40 % • considering a screw jack consisting of a worm gear with linear drive performed by a ball screw, the  total efficiency of the screw jack is between 30 % and 70 % Our Ball screw jacks are available in two different models: • travelling screw (Model A,namely translating type) • travelling nut (Model B,namely rotating type)

Rotating Nut Design ( Traveling Nut ) These jacks have a fixed length lifting screw that rotates . Loads are attached to a flanged “traveling” nut that translates up and down the length of the rotating screw . This type of jack is ideal for applications that cannot accommodate a screw protection tube or that require a flush mount .
