The SWL series worm gear screw elevator is a basic lifting component that uses worm gear transmission screws to complete functions such as lifting, lowering, pushing, and flipping. Widely used in various industries such as machinery, metallurgy, water conservancy, chemical industry, culture, and health, it has a compact structure The advantages of small size, light weight, easy installation, flexible use, good reliability, high stability, and long service life can be directly driven by electric motors or other power sources, or manually operated. This series of worm gear screw elevators can be self-locking, with a load-bearing capacity of 2.5t~120t. There are different structural types and assembly methods, and the working environment temperature is between -20~100 ℃. The lifting height is manufactured according to user requirements.
The excellent performance of the screw lift is largely due to its internal structure——Worm gear structure. This structure was previously used in gearboxes to slow down speed while amplifying torque, meaning that a large torque can be transmitted with very little force. Later on, people discovered that using screw lifts for lifting or lifting activities was also a good choice, so screw lifts emerged.
Due to the internal worm gear structure, the volume of the screw lift is very small and very beautiful, and it will not appear abrupt when used in any fixture. This also makes screw elevators have two speed ratios, fast ratio and slow ratio, in order to adapt to different usage situations. Today, let's first talk about the introduction of the material and processing technology of the worm gear and worm of the screw elevator.
Worm gear material
aluminum bronzeZQAl9-4 has high strength and good wear resistance, and is suitable for working under general loads.
tin bronzeZCuSn10Pb1 has high hardness, good wear resistance, and is not prone to biting. It has good casting and cutting properties and is suitable for working under high loads and high speeds. The worm gears of our DM series products are all made of 10-1 tin bronze.
