Selection and service life assessment method for automobile speed variator bearing

Abstract

Disclosed is a matching and life assessment method of an automobile transmission bearing; based on the common structure, operation gears and the supporting positions of the automobile transmission, the transmission support shaft is used as the basic unit to establish the transmission shaft force models and the analysis calculation modules under the transmission system proposals; the modules are processed with force analysis separately; the modules are independent mutually and can be combined according to the requirements. The concrete steps are as the followings: a) firstly, a transmission system proposal is selected to process the system model selection and the analysis computation module selection; b) the vehicle performance and the relative structural parameters of the transmission are inputted to process the force analysis of the transmission shaft modules; c) the bearing with a certain type and model is selected to obtain the parameters of the selected bearing for the check calculation of the service life of the bearing; d) when the calculated service life values of the bearing modules cannot satisfy the expected service life values, different bearings can be selected in the bearing database to repeat the mentioned steps; e) the proposals are processed with comparison calculation to obtain the satisfactory results; finally, the proper bearing is selected.

AI Technical Summary

Benefits of technology

The technical effect described in this patented process allows companies that want to develop their own branded cars with better performance than previous designs can be identified based upon specific calculations made during designing or manufacturing processes. These improvements help improve engine efficiency while reducing wear and tear over time without compromising safety standards associated with older vehicles.

Problems solved by technology

This patents describes how we can evaluate the quality or lifespan (lifetime) performance of certain types of bearings used in vehicles' drivetrack systems. These bearings may wear out overtime without providing optimal functionality when they don’t last long enough. Additionally, these bearings often require periodic replacement if needed because their service lives quickly degrade after prolonged usage. To address this issue, there has been developed a method called Dynamic Load Analysis ("DLCA") that accurately predicts the expected lifetime of specific components such as bearings based on their static loads while ensuring proper functioning within specified ranges.
