What causes Raymond mill deformation?

The Raymond mill is deformed, generally due to heat, and the conversion of the thermal unit to the structural unit: for highly nonlinear coupling problems, because it can get the best solution. When the coupling problem is not highly nonlinear, the indirect coupling method should be used because the indirect coupling method is more flexible and efficient, and the two analyses can be independent. In the study of thermal deformation, the thermal-structure-coupling coupling method was used for research. The indirect method performs the basic steps of Raymond's thermal stress analysis: converting the unit type and converting the thermal unit into the corresponding structural unit. The analysis process is identical to the steady state and transient thermal analysis processes.

Thermal Deformation Analysis of the Raymond Mill Spindle System: The indirect rule refers to the thermal analysis first, and then the obtained joint temperature is added to the structure as the body load to solve the stress distribution and thermal deformation of the structure. In the whole process of connection analysis, there are conversion problems of thermal unit and structural unit, and the corresponding relationship between thermal unit and corresponding structural unit. Analysis of Raymond's thermal deformation is actually an analysis of the thermal stress problem, that is, the interaction between the two physical fields of heat and stress, which is a problem of coupled field analysis. There are generally two methods of analysis of Raymond mills: direct and indirect.

The direct method refers to the direct use of coupling units with degrees of freedom of temperature and displacement, while obtaining the results of thermal analysis and structural stress analysis. Thermal stress analysis by direct method mainly uses coupling units, including thermal stress coupling units and thermal-stress-electric coupling units. Therefore, always pay attention to the problem of Raymond mill deformation.
