Saide leveling machine screw lift SJB10 worm gear ball screw lift

SJA and SJB both belong to the SJ series screw lift, which has many advantages such as compact structure, small volume, light weight, beautiful appearance, wide power source, easy installation, no noise, multiple functions, multiple supporting forms, flexible use, high reliability, and long service life.

　　Thrust range:0.5-30 tons

　　The stroke can reach 8m, and the stability of the screw and the guiding mechanism need to be considered

　　30% work schedule, if the load rate is low, the work schedule can be appropriately increased

　　The lifting speed is less than 1500mm/min (23mm/s), and in special circumstances it can reach 46mm/s

　　- Efficiency less than 33%, with self-locking function, high reduction ratio L1 self-locking

　　- Accurate positioning, with an additional anti backlash device that can achieve an accuracy of up to 0.05mm

　　- Synchronization, the same motor can drive multiple spiral elevators simultaneously, mechanical synchronization

　　1. Structural Form 1- Axial Movement of Screw Rod

　　Type 2- Screw rotates and nut moves axially

　　2. Assembly type A - screw (or nut) moves upwards;

　　Type B - The screw (or nut) moves downwards.

　　3. There are four types of screw head types: Type I (cylindrical), Type II (flange), Type III (threaded), and Type IV (flat head); The screw head of the Type 2 structural form is divided into two types: Type I (cylindrical) and Type III (threaded).

　　4. Transmission ratio: normal speed ratio (P), slow speed ratio (L)

　Worm gear screw elevator (ball screw elevator)）It is an electromechanical integrated motion execution unit that cleverly combines motors, reduction systems, screw drives, and other components. It can be used alone or combined with multiple units, like building blocks, by connecting components such as right angle steering, couplings, and connecting rods, and can accurately control the lifting, reciprocating, flipping, and other movements of the mechanism according to a certain program. Thus, it can replace traditional hydraulic and pneumatic transmissions in various situations. This motion unit, mainly composed of worm gear and screw elevators, provides a broad design space for engineers in today's digital age to develop products. Widely used in multiple industries such as solar energy, metallurgy, food, and water conservancy.

The square groove shell of SJB ball screw elevator increases the heat dissipation capacity of the shell and prolongs the service life of the lubricating grease. The selection of ductile iron shell material significantly improves the strength and performance of the shell, as well as its wide application at high/low temperatures. Square tail cover design, controlling the screw to not rotate. The processing equipment and assembly technology are the guarantee of high output, and the design concept creates products with strong impact resistance, high strength, low noise, long life, and small size.
