With aid of ANSYS CFD software, the frictional state of sleeveless oil film bearing was studied under specific load, finite element method (FEM) was used to solve N-S equation to calculate the load capacity of film, so that the necessary design parameters which help to form pure fluid friction between frictional pairs among sleeveless oil film bearing could be determined.

Malfunction analysis of taper sleeve of high-speed wire and rod mill and its countermeasures;

The sixty through-holes radial core-pulling is achieved by rotary taper sleeve in the first ejection;the secondary ejection makes the product take off the mold cavity.

Application and maintenance of the sleeve in Anyang Steel high-speed wire mill;

The connection of sleeve-roll neck of oil-film bearing, depending on elastic binding has virtue of stable load transmitting.

The up to date assembly method of the sleeve and roll neck of oil film bearing, used on large-scale 4-h strip rolling mill, is Elastic force joint.

By the simulation test study on the load distribution of the sleeve fraying of oil film bearing , a reliable experimental method and data for bearing life was established for 1580 finish rolling mill in BaoSteel.
