Brief analysis on technology for main shaft assembling,installation and axis adjustment of bulb turbine and generator units of Dadingzishan Navigation and Hydropower Project;

A CAD system for the main shaft device of a mine hoist was obtained using the modern design method The software package belongs to a special automatic CAD system.

The results of analyzing indicate the main shaft device of elevator’s dynamic performance and vibration in reality.

This paper briefly introduces the necessity of the transformation of soviet KJ-type 3 m double-pit elevator and concrete requirements for the transformation,and sums up the ideas and methods for the transformation of the main shaft unit,and arrester,etc.

Mode-Frequency Analysis of CK6132 Spindle Unit with ANSYS;

Finite Element Analysis of Static Stiffness on the Spindle Unit of the Machine Tool;

Research on Disassembly and Recycling Technique for Spindle System of Numerical Control Lathe;

Study on the modes in the spindle system of the machnie tool was carried out, and espcially the relations between the rigidity of their beargings, the natural frequency and the dynamic the compliance were discussed.
