Supply bevel gear ball screw elevator SNB40, special elevator for leveling machines.

Bevel gear lifts are divided into bevel gear screw lifts and ball screw lifts. Compared to worm gear screw lifts, their outstanding features include high efficiency and easy adjustment of the reduction ratio. They also offer convenient installation and use, compact size, low noise, light weight, a wide range of power sources, multiple functions, and high reliability. The products feature a self-locking function, allowing precise control of lifting or pushing height according to the program. Bevel gear lifts come in various structural forms and can be customized according to customer requirements.

SNL screw lifts, compared to worm gear screw lifts, are characterized by high efficiency and easy adjustment of the reduction ratio. They also offer convenient installation and use, compact size, light weight, a wide range of power sources, low noise, multiple functions, and high reliability. This series of products features a self-locking function, enabling precise control of lifting or pushing height according to the program. They come in various structural forms, and the lifting height can be manufactured according to user requirements.

SNB screw lifts feature a ball nut housed within the shell, utilizing a ball screw and nut made of hardened alloy steel to carry the load between the nut and screw. This rolling action reduces friction between the nut and screw, allowing smooth movement of the load. Due to improved efficiency and rolling performance, ball screws can operate at higher speeds or with larger duty cycles compared to standard trapezoidal screw lifts.

High-precision screw lifts are suitable for industries such as stainless steel precision panel and wafer manufacturing. They save space and enhance high precision and high speed, significantly increasing production output.

The lifespan of ball screw lift series products is primarily determined by the lifespan of the ball screw and components such as worm gears. We mainly verify the lifespan of the ball screw; worm gears may experience wear but generally have a longer lifespan than ball screws. This type of lift is often used in environments requiring high precision, such as high-end automated equipment.

The working principle of the ball screw lift brake is as follows: one set of friction pairs in the brake is connected to the fixed frame, while the other is connected to the rotating shaft of the mechanism. When the friction pairs are pressed together, braking occurs; when separated, braking is released, allowing the mechanism to move.

Based on their working state, ball screw lift brakes can generally be divided into normally closed and normally open types.

1. Normally closed: When the mechanism is not in operation, the brake is in a closed braking state; when the mechanism is operating, the control mechanism automatically releases the brake first. Tower crane hoisting and luffing mechanisms use normally closed brakes.

2. Normally open: The brake is usually in a released state and is engaged through mechanical or hydraulic mechanisms when braking is required. The slewing mechanism of tower cranes and construction hoists uses normally open brakes.

Based on their construction, ball screw lift brakes can be divided into the following three categories:

1. Band brake: A steel brake band wraps radially around the brake drum to generate braking torque.

2. Block brake: Two symmetrically arranged brake shoes radially clamp the brake drum to generate braking torque.

3. Disc and cone brake: Metal discs or cones with friction linings are axially pressed together to generate braking torque.

Application range of ball screw lifts:

1. Lifting, displacement, clamping, and flipping actuators in production lines.

2. Installation, clamping, lifting, and flipping devices in metallurgical equipment.

3. Vehicle lifters, flexible tooling, and welding lifts in the automotive manufacturing industry.

4. Lifting devices for monocrystalline and polycrystalline silicon ingot furnaces in the photovoltaic industry and solar tracking systems.

5. Actuators in aerospace and astronomical telescopes.

6. Lifting devices for stage platforms.

7. Various actuators in industries such as shipbuilding, water conservancy, food, warehousing, casting, woodworking machinery, and food machinery.

8. Lifting devices on vertical and gantry machine tools, suitable for high-speed, high-frequency, and high-performance applications, primarily composed of precision ball screw pairs and high-precision worm gear pairs.

High efficiency: A small driving source can generate significant thrust. High speed: Compared to trapezoidal screws, speed is greatly improved, enabling smooth and high-speed operation. Long service life: The use of high-quality ball screws extends the working life by more than three times.
