Do you know the important role of oil seals for screw jacks?

The screw elevator is the most widely used transmission component in the field of mechanical automation. Compared with the traditional transmission method, it is more convenient to install and use. Compared with the emerging electric push rod and electric servo cylinder, Its load and range of use are more advantageous, so the screw jack is very popular now, and has been recognized by many customers.
The internal structure of the screw elevator is a worm gear structure. This mechanical structure not only has its own reduction ratio, but also has a long service life. The whole machine of the elevator is composed of box, worm gear, screw, bearing, oil seal and other components. Today we mainly talk about the important role of the oil seal for the screw elevator.
The oil seal is actually used in mechanical equipment to seal the rotating shaft oil leakage seal. Because the output shaft and input shaft of the elevator will rotate rapidly during operation, in order to prevent the worm from leaking in the gap during rotation and to prevent other dust, sand and other contaminants from invading from the outside, it is necessary to use an oil seal. The outside of the oil seal is a cylindrical shape. This is to ensure a static seal to the box. It is made of an external rubber material, an internal metal skeleton, and a spring-loaded sealing lip to ensure a more reliable seal.
There are a few points to note when using the oil seal. One is to pay attention to the temperature inside the box. If the temperature is too high, the oil seal will be deformed and lose its function. Another point is to pay attention to the pressure of the oil seal. If the pressure in the box is too high, a pressure-resistant oil seal should be used.
