Screw Jack, also known as a helical drive mechanism.It is primarily used to convert rotary motion into linear motion or vice versa. There are those that mainly transmit energy, such as spiral presses and jacks; others that primarily transmit motion, like the feed screws on machine tool tables; and still others that adjust the relative positions of parts, such as spiral drive mechanisms. Screw lifters come in both sliding friction and rolling friction types.
SNLThe main features of screw jacks compared to worm screw jacks include high efficiency, ease of adjusting the reduction ratio, ease of installation and use, compact size, lightweight, wide power source, noiseless operation, diverse functionalities, and high reliability. This series offers self-locking capabilities and can accurately control and adjust lifting or advancing heights according to programmed instructions. The structure is versatile, with lifting heights customizable to meet user requirements..
This lift mechanism synchronizes the base plate's rise and fall through corner movement, and connects it with four-point, six-point, and twelve-point motion chains to lower the base plate height, reducing motion errors. Additionally, the flat rise and fall function allows for direct and rapid performance, saving space, increasing production, and enhancing quality stability.
SNBScrew Jack,Characterized by ball nuts housed within the shell, utilizing ball screws and nuts, made from hardened alloy steel, bearing the load between the nut and screw. This rolling action reduces friction between the nut and screw, allowing for smooth movement of the load. Due to enhanced efficiency and rolling performance, ball screws can operate at higher speeds or over longer working cycles compared to standard trapezoidal screw lifts.
High precision screw jacks, suitable for the industry of stainless steel precision sheeting and wafer panel factories. Space-saving and capable of enhancing high precision and speed, they can significantly boost production output.
Features of screw jack:
1The working principle involves ball bearings placed between the screw thread and nut.
2When the lead screw or nut turns, the ball bearings roll along the thread groove, generating rolling friction between the lead screw and nut as they move relative to each other. To prevent the ball bearings from rolling out of the groove, return guide devices are installed at both ends of the nut's helical slots.
3They form a circulating loop with the threaded raceways, allowing the ball bearings to circulate within the nut's raceway.
