Problems solved by technology

Under the action of the oil film, the force between the bearing seat and the journal will be dispersed to a curved surface, and the relevant structural design based on the structural strength of the bearing seat or journal calculated by the concentrated force is often an overdesign. Not only leads to waste of materials, but also goes against modern lightweight design principles

Abstract

The invention discloses a structural strength calculation method and apparatus used for a bearing seat or a journal of a sliding bearing. The method comprises the steps of calculating a concentrated force of interaction between the bearing seat and the journal; determining a distribution function of the bearing force of the interaction between the bearing seat and the journal; determining a parameter value of the distribution function according to the distribution function and the concentrated force; and calculating structural strength of the bearing seat or the journal according to the distribution function and the parameter value. According to the structural strength calculation method and apparatus used for the bearing seat or the journal of the sliding bearing, the problem of overdesign of the bearing seat or the journal in the prior art is avoided, so that manufacturing materials are saved.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a method and device for calculating the structural strength of a bearing housing or journal of a sliding bearing. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotation, reduce the friction generated during its movement, and ensure its rotation accuracy. In sliding bearings, the interaction force between the bearing seat and the journal during the working process is called bearing force. When designing the structure of the bearing seat or journal, the structural strength of the bearing seat or journal can be calculated through the bearing force, and then the structural design can be improved according to the calculated structural strength. [0003] At present, the single concentrated force of the interaction between the bearing seat and the journal is usually calculated by the...
