How to reduce the speed of the worm screw elevator

The center of the worm gear is an internal thread structure, which is equivalent to the nut of the lifting screw, which matches the lifting screw.The lifting speed is equal to the input speed of the worm divided by the reduction ratio of the worm gear, and then multiplied by the pitch of the lifting screw.Due to its structure, this kind of screw lift is generally lubricated with grease, and some series are lubricated with lubricating oil, which has the advantages of longer life and stable operation than the grease lubricated series.The worm gear screw lift is to use the worm gear and the worm to achieve the purpose of speed reduction.
Worm screw lifts are generally used for low-speed and high-torque transmission equipment. The power of electric motors, internal combustion engines or other high-speed operation is achieved by meshing the gears with a small number of teeth on the input shaft of the worm gear box with the large gears on the output shaft. For the purpose of deceleration, ordinary screw elevators will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.The screw lift is composed of gear pairs at all levels.For example, using a small gear to drive a large gear can achieve a certain purpose of deceleration, and then using a multi-stage structure can greatly reduce the speed.
