HD series helical gear reducer 90 degree gearbox

Screw jack lift system structures include miter gearboxes, screw jacks, electric motor or gear reducer, hand wheel, pillow block bearings, jaw couplings and line shaftings.  Screw Jack System Features: 1. Heavy duty, self-locking, positioning precision, uniform lifting speed, fully synchronization, easy installation, easy operation 2. Two screw jacks system, three screw jacks system..forty screw jacks system. 3. Extremely high capacity requirements of need very precise up or down control. It's of high mechanical, they are an excellent choice when hydraulic, pneumatic or chain systems are prohibitive choices. 4. Widely used in wood working machines, plastics processing machines, textile machines, assembly equipment in the automobile and aircraft industries, food and beverage production equipment as well as packaging machines.

Lude Transmission stainless steel screw jacks are specifically designed for positioning and lifting applications that are located in wet, corrosive and harsh environments. They can be trapezoidal type or ball type. Metallurgical properties of stainless steel allow it to remain ductile even at very low temperatures.These mechanical jacks are available in 2 ton through 25 ton capacities. Upright or inverted jacks operate at full capacity in tension or compression. Features: All exposed surfaces and components feature stainless steel or bronze construction Nitrile rubber seals protect all internal mechanisms. Tapered or ball thrust bearings provide rugged reliability Choose one of four standard end conditions Protective boots available Anti-backlash devices available

Travelling Nut Screw Jacks ,or Rotating Screw 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.

The Electric Linear Actuator can be driven by DC motor 12/24/36/48V, single phase / three-phase AC motor 220/380V, stepper motor.

Cubic ball screw jack has the feature of the compact structure and high precision ball screw.

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)

screw jack is a gearbox assembly (either worm gear or bevel gear) and a transmission product (lead screw, ball screw or roller screw) which through use of a motor is used to convert rotary into linear motion.

Hand wheel worm gear screw jack is composed of hand wheel or hand crank and a complete set worm gear screw jack with internal worm and worm gear sets, standard hand wheel or hand crank.
