Title:
SEALING EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2005/075858
Kind Code:
A1
Abstract:
This invention relates to one sealing equipment used between a first surface and a second surface which can move relatively. Said equipment includes a main body and at least a sealing part. The main body and the sealing part are located parallelly between the first surface and the second surface, and the outer surface of the main body contacts with one of the first surface and the second surface, while the sealing part contacts with the other of the first surface and the second surface. The sealing equipment of this utility model can achieve a perfect sealing effect, such as it can prevent the lubricating oil of bearings in rolling mill from leaking and make the lubricating oil flow regularly along one direction to reuse through reclaiming. Thus, the sealing equipment of this inventon model can save lubricating oil and ensure the lubricating of bearings and extend the life of bearing and the like.
