Experiments and models for the thermal response of railroad tapered-roller bearings
The need to understand and quantify the heat transfer paths within tapered-roller bearings is of great importance in the railroad industry since bearing cup temperature measurement is the primary tool utilized in the removal of distressed bearings from service. Experiments were performed to acquire temperature histories at several locations on a stationary bearing subjected to heat sources imbe...
متن کاملTapered Roller Bearings Cage to Improvement Design
In order to improve the utilization of materials, improving stamping cage processing methods, the single row tapered roller bearing cage is improved from structural strength, puts forward whole stamping cage a type of structure. Use ANSYS finite element analysis to the different structure and the thickness cage. Get the stress contours of the cage, based on equal strength design principles. Get...
متن کاملDesign Optimization for Tapered Roller Bearings Using Genetic Algorithms
The design of tapered roller bearings has a fundamental influence on the performance, life and reliability of the bearings. Consequently, this also affects the operating quality and the economization of machines on which the bearings are used. The responsibility of bearing designers is to select an optimal scheme from all the possible alternative designs, or simply put to make the best choice. ...
متن کاملThermal models of railroad wheels and bearings
The rolling surface for railroad wheels can be a heat source that may have an impact on the performance of the wheel bearing. In this study, experimental data from an electrically-heated railroad wheel set is analyzed by constructing thermal models of the wheel set. A steady finite-element model, a steady-analytical model, and a transient lumped-parameter model are discussed. Model parameters a...
متن کاملPrediction of Defects in Roller Bearings Using Vibration Signal Analysis
Roller bearing failure is a major factor in failure of rotating machinery. As a fatal defect is detected, it is common to shut down the machinery as soon as possible to avoid catastrophic damages. Performing such an action, which usually occurs at inconvenient times, typically results in substantial time and economical losses. It is, therefore, important to monitor the condition of roller beari...
