Hollow shaft type hydrostatic bearing dynamic designing method

Abstract

The invention discloses a hollow shaft type hydrostatic bearing dynamic designing method. By means of the method, dynamic design of a hollow shaft type hydrostatic bearing is achieved through the steps of conducting scaling hollow shaft type hydrostatic bearing preliminary arrangement, conducting a scaling ball mill hollow shaft type hydrostatic bearing static simulation research, conducting a hollow shaft type hydrostatic bearing static experiment research with qualified scaling ball mill static simulation, conducting a hollow shaft type hydrostatic bearing dynamic simulation research with qualified scaling ball mill static experiments, conducting a hollow shaft type hydrostatic bearing dynamic experiment research with qualified scaling ball mill dynamic simulation and conducting hydrostatic bearing optimization design. Compared with the existing similar designing methods, the method improves running reliability of the hollow shaft type hydrostatic bearing and reduces manufacturing cost, use energy consumption and maintenance cost of the hollow shaft type hydrostatic bearing.

Description

technical field [0001] The invention relates to a dynamic design method, in particular to a dynamic design method of a hollow shaft static pressure bearing. Background technique [0002] The specifications of ball mills working in heavy-duty, low-speed and harsh environments continue to increase. As a key component, hydrostatic bearings have higher requirements for their load-carrying capacity, reliability, service life, maintenance and energy consumption. Pressure bearings, there are no design standards and specifications in foreign countries. At present, my country's ball mill industry has not yet mastered the design theory and core technology of large ball mill hydrostatic bearings. Large ball mill hydrostatic bearings designed by empirical analogy have low operating reliability and failure. Occurs from time to time, and the operation energy consumption and maintenance cost are high, so it is urgent to overcome the design theoretical problems and key technologies of the hyd...
