SEALING METHOD FOR VACUUM FURNACE WITH DRIVING MECHANISM AND STRUCTURE THEREOF

摘要

The present invention relates to a method for maintaining the airtightness of a vacuum installation with a drive device and a structure thereof. The object of the present invention is to provide a lubricating oil injection method of a rotating shaft with a drive device at a time by always supplying a certain amount of lubricating oil so as to provide smooth lubrication. It is to provide a method and structure for maintaining confidentiality.;The configuration of the present invention and the drive motor for generating a rotational force; A drive shaft coupled to the drive motor to transmit rotational force, and a structure for supplying and sealing lubricating oil to the drive shaft, the bearing being installed on both sides of the drive shaft to support and rotate the load of the drive shaft; Lubricating oil supply means for simultaneously supporting both bearing outer diameter parts and having a lubricating oil supply passage therein; A lubrication port connected to supply lubricating oil of a lubrication barrel to the lubricating oil supply means; A lubricating oil supply hose connected to one side of the filling hole; It consists of a gas tank connected to the other side that is not connected to this hose, and characterized by a confidentiality method using the same.;Hermetic, Lubricant, Oil Cylinder, Drive Shaft, Drive Motor
