SWL series worm gear screw jacks are widely used in industries such as machinery, metallurgy, construction, and water conservancy equipment. They offer numerous functions including lifting, lowering, and, with the aid of accessories, propulsion, tilting, and various height adjustments. The SWL worm gear screw jack is a basic lifting component with many advantages, including compact structure, small size, light weight, wide range of power sources, no noise, easy installation, flexible use, multiple functions, various accessory combinations, high reliability, and long service life. It can be used individually or in combination, and can accurately control and adjust the lifting or propulsion height according to a specific program. It can be directly driven by an electric motor or other power source, or manually.
Worm gear screw jacks, as functional components, have been widely used in various industries. Examples include: transmission devices and CNC actuators in the machinery industry; rolling mill motion devices, ladle lifting and tilting devices in steel mills, and motion transmission devices in inaccessible locations in the metallurgical industry; vehicle lifting frames, large flexible clamping and indexing fixtures, and welding robots in the railway vehicle industry; lifting devices and automatic or remote-controlled opening devices for large doors and windows in the construction industry; gate opening devices, radar and solar-powered remote sensing devices in industries such as water conservancy; lifting devices in medical equipment, lifting stages, and the automotive manufacturing industry; and transmission devices in aerospace, defense, and military applications. In fact, worm gear screw jacks can be used almost anywhere mechanical displacement transmission is required.
The maximum temperature of the screw jack under normal operating conditions should not exceed 45 degrees Celsius. If high temperature occurs, the machine should be stopped immediately for inspection. Generally, this problem is caused by selecting a screw jack of too small a tonnage, resulting in overload, or by the worm gear and worm wheel end caps being pressed too tightly, leading to high temperature. Input speed is also a possibility. Screw jacks are grease-lubricated. The maximum speed of the worm shaft of the screw jack should not exceed 1000 min/s. If the input speed is too high, high position and jamming may also occur. The solution to high temperature is to reduce the input speed, check whether the end cap is too tight, and check whether the screw jack is lacking oil.
