Design of pure static pressure sliding shoe structure for fixed end and free end in tube mill supporting device

Abstract

The invention provides a design of a pure static pressure slide-shoe structure at a fixing end and a moving end of a supporting device of a tube mill. In the supporting device of the tube mill, the moving end, namely, a feeding end is designed to a radical pure static pressure slide-shoe structure which can move axially, the fixing end, namely, a discharging end is designed to a combined pure static pressure slide-shoe structure that can not only anti thrust axially but also can move radially, and in the combined pure static pressure slide-shoe structure, axial direction and radical directionare combined. In the design of the invention, the value range adopts optimized design, and is affirmed after being tested. The structure has the characteristics of good self-calibration property and strong on-load property. An axial thrust bearing at the fixing end has the advantages of simple structure, good anti-thrust property and long service life.

Description

technical field [0001] The invention belongs to the technical field of tube mill support devices, and in particular relates to a design method of pure static pressure sliding shoes at fixed and movable ends in a tube mill support device. Background technique [0002] At present, large-scale tube mills at home and abroad all adopt the sliding shoe bearing support system, and its design structure is a dynamic pressure bearing structure under normal working conditions except for the stop mill. The Achilles heel of the dynamic pressure sliding shoe is high temperature of the sliding shoe, short bearing life, frequent tile burning, low equipment operation rate, high precision and complicated processing of the slip ring. In order to reduce the temperature of the dynamic pressure sliding shoe bearing, we have taken many measures, including increasing the heat shield, increasing the area of ​​the lubrication cooler, etc., but the effect is limited and the problem has not been fundam...
