Sede Ball Lift Integrated Machine SNB Spiral Screw Lift Vertical Small Lift
Umbrella gear elevators are divided into umbrella gear screw elevators and ball elevators. Compared with worm gear screw elevators, their characteristics are that they are easy to use and the reduction ratio is easy to adjust. At the same time, it has the characteristics of easy installation and use, small size, no noise, light weight, wide power source, multiple functions, and high performance. The product has a self-locking function, which can accurately control the lifting or pushing height according to the program. The umbrella gear elevator has various structural forms and can be customized according to customer needs.
Compared with worm gear screw lifts, SNL screw lifts are mainly characterized by their ease of use, easy adjustment of reduction ratio, convenient installation and use, small size, light weight, wide range of noise free power sources, and high versatility. This series of products has self-locking function, which can accurately control and adjust the lifting or pushing height according to the program. There are various structural forms, and the height can be manufactured according to user requirements
The SNB screw lift is characterized by a ball nut placed inside the housing, using ball screws and nuts, made of quenched alloy steel, and carrying the load between the nut and the screw. This rolling action can reduce the friction between the nut and the screw, thereby allowing the load to move smoothly. Due to the improvement of work efficiency and rolling performance, compared with ordinary trapezoidal screw elevators, ball screws can operate at high speeds or large working cycles.
High precision screw lift, suitable for the panel factory industry such as stainless steel precision plate and chip manufacturing. It can save space and improve high precision and speed, which can greatly increase production.
The lifespan of the ball screw elevator series products is mainly determined by the lifespan of the ball screw and components such as worm gears and worms; We mainly verify the lifespan of ball screws. Worm gears and worms may experience wear, but their lifespan is generally longer than that of ball screws. This elevator is widely used in high-precision automation equipment in environments with high precision requirements.
The working principle of the ball screw elevator brake is: one set of brake friction pairs is connected to the fixed frame; The other group is connected to the rotating shaft of the mechanism. When the friction pair is in contact and compressed, it produces a braking effect; When the friction pair separates, the braking effect is released and the mechanism can move.
According to the working state, ball screw elevator brakes can generally be divided into normally closed and normally open types.
1. Normally closed: When the mechanism is in a non working state, the brake is in a closed braking state; When the mechanism is working, it automatically releases the brake first. The lifting and slewing mechanisms of the tower crane are both normally closed.
2. Normally open: The brake is usually in a released state, and when braking is required, it is accomplished through mechanical or hydraulic mechanisms. The slewing mechanism of the gearbox for tower cranes and construction elevators adopts a normally open type.
According to different constructions, the brakes of ball screw elevators can be divided into the following three categories:
1. Belt brake: The brake steel strip wraps around the brake wheel radially to generate braking torque.
2. Block brake: Two symmetrically arranged brake pads that radially grip the brake wheel to generate braking torque.
3. Disc and cone brakes: Disc and cone metal discs with friction lining are pressed against each other in the axial direction to generate braking torque.
Application scope of ball screw elevator:
1. Execution devices such as lifting, displacement, clamping, and flipping in the production line
2. Devices and clamping, lifting, and flipping devices in metallurgical equipment
3. Hoists, flexible fixtures, and welding lifts in the vehicle manufacturing industry
4. Lifting device and solar power generation tracking device for monocrystalline silicon and polycrystalline silicon ingot furnaces in the photovoltaic industry
5. Remote control actuators for aerospace, astronomical telescopes, etc
6. Stage lifting device
7. Various actuators in industries such as shipbuilding, water conservancy, food and storage, casting, woodworking machinery, and food machinery. 8. Lifting devices on machine tools such as vertical lathes and gantry cranes are suitable for high-speed, high-frequency devices, and mainly consist of precision ball screw pairs and worm gear pairs.

Only a small driving source is needed to generate a large driving force. High speed: Compared to trapezoidal screws, there is a significant increase in speed, allowing for easy and high-speed operation. Long service life: By using high-quality ball screws, its working life is increased by more than three times.
