Abstract
The invention provides a quasi-static analytical model analysis method of a deep groove ball bearing considering combination angle misalignment, and belongs to the technical field of contact mechanics. The method comprises the following steps of: under the condition of less research on a deep groove ball bearing in an angle misalignment form with misalignment of a central axis azimuth angle time varying, calculating an abnormal pre-tightening load caused by misalignment of a combination in the deep groove ball bearing to obtain an abnormal pre-tightening force caused by misalignment of the combination angle; and then a quasi-statics model of the deep groove ball bearing under the action of an external load is established based on a double-layer Newton Laplace iteration method, a Newton Laplace method based on Jacobian matrix analysis is given, and the sensitivity of the solving algorithm to an initial value condition is relatively low. The contact and friction characteristics of the deep groove ball bearing with the misaligned combination angle under the influence of multiple factors can be obtained, not only is the influence of misalignment of a single angle, and technical support is provided for follow-up research of the bearing.
