Problems solved by technology

Compared with the empirical formula method, the calculation accuracy of this method has been greatly improved, but because the method does not fully consider the physical background of the angular contact ball bearing load distribution problem, the results obtained will have no physical meaning and need to be repeated Adjust the initial value of the iterative calculation until a reasonable result is obtained. Sometimes this trial calculation process is relatively long. In some cases, it is even difficult to obtain the real load distribution results, which cannot meet the engineering requirements in terms of calculation efficiency.

Abstract

The invention discloses a method for calculating load distribution of an angular contact ball bearing. The method comprises the following steps of obtaining a load solving method and a contact deformation solving method of a rolling body in the angular contact ball bearing; dividing the rolling bodies into Team_1 to Team-N along the action line direction of a radial load borne by the bearing; setting the value of n, and trying to calculate the deformation from Team_n to Team_N; and checking whether the contact deformation from Team_n to Team_N has a negative value or not, if yes, adjusting the value of n and then executing the trial calculation step again, and if not, determining that the solution of the load distribution solving method from Team_n to Team_N is the load distribution of the angular contact ball bearing. The method provided by the invention has the technical effects that the calculation result not only can ensure the convergence requirement in mathematics, but also can ensure the rationality requirement in physics. Here, the physical rationality means that the contact deformation between the rolling body and the raceway of the angular contact ball bearing, calculated by the method, is only compressive deformation, but does not generate tensile deformation.

Description

technical field [0001] The disclosure belongs to the field of bearing load calculation, and in particular relates to a calculation method for load distribution of an angular contact ball bearing. Background technique [0002] Angular contact ball bearings are a support component widely used in the field of rotating machinery. The main components of this bearing include: inner ring, outer ring, rolling elements and cage. This type of bearing realizes the connection between the stationary part and the moving part of the rotating machinery system, or the connection between different moving parts, by using the movement of the rolling elements along the inner raceway and the outer raceway. For angular contact ball bearings, the contact between the rolling elements and the inner and outer raceways is a point contact. [0003] The purpose of solving the load distribution of angular contact ball bearings is to obtain the displacement of the bearing, the contact deformation and con...
