BMSeries Worm Gear Screw JacksBall bearingsSpiral Elevator)An integrated mechanical and electrical motion execution unit that ingeniously combines motors, reduction systems, screw drives, etc. It can be used individually or in a combination of multiple units, similar to building blocks, connected with right-angle turners, couplings, and connecting rods, allowing for precise control of the lifting, reciprocating, and flipping movements of the mechanism. This unit, primarily featuring worm gear and screw lifters, can replace traditional hydraulic and pneumatic transmissions in various applications, providing engineers with a broad design space in the digital age. It is widely used in industries such as solar energy, metallurgy, food processing, and water conservancy.BMThe unique square-socket housing of the ball screw lifting jack enhances the heat dissipation capacity of the outer shell and extends the service life of the lubricant. The choice of cast iron material for the housing significantly improves the strength and performance of the housing, as well as its ability to withstand high temperatures./Wide application at low temperatures. Square tail cover design prevents the lead screw from rotating freely. Advanced processing equipment and assembly techniques ensure high-quality products, while the innovative design concept creates products with strong impact resistance, high strength, low noise, long service life, and compact size.

Ball screw screw jack service life calculation
Ball screw lifting jackBMThe lifespan of the series products is mainly determined by the lifespan of the ball screw and other components such as worm gears and worms.;We primarily inspect the service life of ball screw shafts; worm gears are subject to wear.,But typically, its lifespan is longer than that of ball screws.
Expected life of ball screwL10Certainly90%The operating distance that the ball screw can reach or exceed before metal fatigue failure. Unit: million millimeters. Expected lifespan of the ball screwL10Not a quality guarantee,Expected lifespan is to be achieved with proper maintenance, absence of contaminants, and correct lubrication.
If the expected service life of the ball screw needs to exceed90%Multiply the expected lifespan by the following coefficient.
95%: L10x62% 96%:L10x53% 97%:L10x44% 98%:L10x33% 99%:L10x21%
If you need assistance in selecting a screw jack that meets your requirements, please provide the following parameters::
1Lifting Weight, Unit:KG;
2.Lifting speed:Every minute or second, the lead screw or nut moves a certain length;3Lead screw motion form:Ball screw movement or nut movement;
4.One or several elevator installations;
5Is it directly connected to the drive motor?
Screw Jack联动Platform
The worm screw lifting machine work platform consists of one or more lifting machines, powered by a motor (or handwheel) and coordinated with other components for synchronized and smooth lifting.
The lifting platform of the screw jack, whether it's a 2, 3, or 4-axis drive, we recommend using a single motor to complete the operation. This is because each motor has a speed difference in its RPM, making it difficult to achieve synchronization and stability when multiple motors are used.
Common combinations of screw jack platforms include two, four, and eight units, etc. Two units are often interconnected.I and T models are available. Compared to the T-type structure where the drive source is in the middle, the elevator experiences more even force distribution, resulting in a more stable transmission effect. Four interconnected models are available: T-type, U-type, and H-type. The H-type development model and 2H-type multi-unit combinations are also available. Customers can choose based on their own installation space and other requirements. For more selection options, please consult our technical staff.
Composed of a worm gear reducer and a lifting screw, the reduction component is a worm drive, which uses the worm to drive the worm gear for deceleration. The worm gear center features an internal threaded structure, akin to the nut of the lifting screw, and is compatible with the lifting screw.
The lifting speed of the reducer equals the input speed of the worm divided by the reduction ratio of the worm and worm gear, then multiplied by the pitch of the lifting screw. Due to its structural nature, this screw lifting machine is typically lubricated with grease, with some series using oil lubrication, which offers the advantages of longer lifespan and more stable operation compared to those lubricated with grease.
