You are here : Non-contact seal carton machine introduced
Carton machinery commonly used form of non-contact seals have the following three ways:
1, aperture seal. The simplest structure is to cover the shaft and bearings to leave the radius between the hole clearance is about 0.1 ~ 0.3mm in the gaps. This is the use of grease lubrication of the bearing has a certain sealing effect. Cover through holes in the car bearing the ring into the grooves filled with grease, can improve the sealing effect.
2, labyrinth seal. Maze is rotated and fixed by the seal formed between the gaps is tortuous. Usually arranged along the radial maze, the smallest aperture is taken to be 0.2 ~ 0.5mm. Often fill in gaps grease.
3, the rejection of the oil ring seal. The shaft or equipment out of oil ring grooves, by centrifugal force along the axis of the outflow of oil to get rid of the surface, then goes back to the oil tank assembly, and thus play a seal. However, loss of sealing effect after parking, sealing Guchang and other forms of joint use. Rejection bearing oil pan installed inside by centrifugal effect is likely to get rid of oil into the bearing interior, played the role of seals
