Abstract

The invention provides a dynamic seal device of vacuum equipment and the vacuum equipment and relates to the technical field of the vacuum equipment. The dynamic seal device of the vacuum equipment and the vacuum equipment aim to solve the problem of poor sealing performance of existing vacuum equipment caused by displacement of bearings at the two ends of a rotating shaft. The dynamic seal devicecomprises a drive assembly and a seal assembly, wherein the drive assembly is located outside a vacuum chamber and fixedly connected with the wall of the vacuum chamber, the drive assembly is connected with a conveying device, and the seal assembly is used for sealing the junction of the drive assembly and the vacuum chamber. By arranging the drive assembly outside the vacuum chamber and arranging the seal assembly between the drive assembly and the outer wall of the vacuum chamber, seal is reliable and the vacuum environment of the vacuum chamber is kept; and as the drive assembly is arranged outside the vacuum chamber, when operation pressure switching is carried out in the vacuum chamber, the drive assembly is not affected or shift to cause damage and abrasion to the seal assembly, andairtightness of the vacuum chamber is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of vacuum equipment, in particular to a dynamic sealing device of vacuum equipment and vacuum equipment. Background technique [0002] In the automatic and intelligent production line of mechanical processing, vacuum equipment is an indispensable production equipment for providing a vacuum environment for mechanical processing. It turns out that this process requires a vacuum chamber to provide power. Many existing vacuum equipments are equipped with a power source in the vacuum chamber so as to realize the above-mentioned automatic handling process. If the power source is installed in the vacuum chamber, there will be certain vibration in the vacuum chamber, especially in the state of frequent pressure switching, the fixed bearings at both ends of the rotating shaft may have a certain amount of movement, causing the radial runout of the rotating shaft and wearing the seals. cause a system leak.
