Motion Process

Considering the radial load and rotational speed of bearing, the finite element (FE) model for dynamic contact of deep-groove ball bearing was established by the software — ANSYS. Based on explicit dynamic finite element method, the nodal displacement, velocity of rolling bearing and stress of rolling element were obtained. Through calculating, it could be seen that the maximum velocity was shown at the contact point between the rolling element and the inner ring, while the minimum velocity was shown at the contact point with outer ring. The maximum equivalent stress and shear stress of the bearing were also occurred at the contact point of raceway, and the inner ring was bigger than the outer ring. The finite element simulation of the motion process for deep-groove ball bearing had a guiding significance to the research of dynamic load between the rolling bearing components as well as the dynamic characteristics of rolling bearing.

Vibration Measuring

Measurement of the damage of elements in bearing can be by measuring the vibration generated in the form of a frequency signal when the pad is rotating. Measurement of vibration on the bearing by using vibration measuring instrument. Damage to the rolling bearing includes damage to the cage, outer ring, inner ring and balls.

Raceway waviness error is the main reason to cause rolling elements to vibrate along axial direction and emit noise. In this paper, the mechanical analysis on deep groove ball bearing is carried out. With auto-correlation function, random surface waviness of both inner and outer raceways is simulated. A contact model of rolling elements and raceways considering surface waviness is established. Combining with the theory of acoustic equation, a calculation model is established for the noise caused by vibration of rolling elements and inner ring. The results show that with the decrease of machining accuracy, the noise of rolling elements increases due to axial vibration; with the increase of rotation speed, the noise also increases. Besides, the spectrum of radiation noise of inner raceway with different waviness amplitudes is given. The results indicate that the 3-D waviness on raceway surface has an influence on the vibration and the noise emitted by both rolling elements and inner ring, and provide guidance for sound control in deep groove rolling bearing.

This paper describes a deep groove ball-bearing analysis which has been developed to simulate acoustic emission occurring during ball-bearing operation. The computer simulation is useful to clarify experimental research on rolling contact fatigue initiation using the acoustic emission technique. Results show the ability of the method to detect and to locate a subsurface defect, due to rolling contact fatigue, before the rolling bearing failure occurs. The subsurface defect can be accurately located within the inner ring of a deep groove ball-bearing operating under radial load.

With the application of explicit dynamics and probability finite element method, reliability virtual experiment of deep groove ball bearing is carried out. Based on self –adaptive mesh module of the ANSYS/LS-DYNA, true numerical simulation of the working process is presented after the three-dimensional finite element bearing model is built. Then, the contact stress and strain among balls, retainer and inner (outer) race and also the pressure law during the contact process are obtained. As the randomness of manufacture and assemblage tolerance is inevitable, Monte Carlo method is adopted when samples the bearing system. From the random sampling, a large sample data of the maximum contact stress is got and the reliability coefficient is calculated; and the contribution of each original manufacture error to the reliability sensitivity of the bearing is analyzed. Reliability virtual experiment offers a theoretical reference to fatigue strength calculation and dynamic optimum design of the bearing system, and the analysis process is easy to be program controlled.

The heat generating mechanism inside the cavity of rolling bearing is analyzed and the convective heat transfer coefficient of bearing raceway surface in different rotational speed is calculated under the oil-air lubrication and the spray lubrication in this paper. The fluid domain geometry model of deep groove ball bearing SKF6208 is established, employing the flow field module in Workbench. The comparing simulations of the temperatures of rolling bearing cavity under the oil-air lubrication to the spray lubrication are done in different rotational speed. The simulation results show that the highest temperature of bearing cavity with the oil-air lubrication is almost the same to the spray lubrication when the bearing rotational speed is lower, and the highest temperature of bearing cavity with the oil-air lubrication is far lower than the spray lubrication when the bearing rotational speed is higher. Those conclusions verify the advantages of the oil-air lubrication in high rotational speed.

Speed of rolling bearing and flow rate of air have important influences on the bearing’s working temperature under the oil-air lubrication mode. Based on basic principle of lubrication, one of the heat productivity equations of deep groove ball bearing is selected to calculate the heat value of bearing’s cavity. The bearing’s temperature field is simulated by Fluent at different rotational speeds and air flow rates. Results of the simulation show that the highest temperatures of bearing have a quantitative relationship with the bearing’s rotational speeds. The relationships between the velocity of inlet and heat transfer coefficient, viscosity of the lubricant and the heating of bearing are analyzed in the end of this paper.

Deep Groove Ball Bearing

Due to the same series of rolling bearing standard part with the same topology structure and different dimension parameters, a series of rolling bearing products can be designed by parametric design method. Based on the development tool of Pro/Program and family table combined with three-dimensional modeling, this paper takes deep groove ball bearing for example to discuss the means and steps of rolling bearing parametric design. By entering the relevant parameters, such as the bearing outside diameter, bearing inside diameter, bearing width, ball number and other known conditions, we can accurately and quickly generate a new rolling bearing solid model. The result shows that in the design environment of Pro/ENGINEER, using parametric design to make three-dimensional modeling can shorten design cycle time and improve design efficiency significantly.

Element Simulation

Based on finite element simulation, the temperature field model for the frictional pair of third rail and collector shoe under the coupling of contact resistor thermal and friction thermal was established. The method of coupling the two kinds of thermal was given in detail, the temperature field was calculated, and the maximum coupled temperature changing under different electric current, velocity, and displacement of the model was studied. The results show that the temperature raising effect of friction thermal and contact resistor thermal is different. In the process of mechanical friction without electric current, the highest temperature is in the contact center line, the temperature distribution expands around the contact zone in descending tendency. But in couple condition, the temperature distribution with electric current expands around the contact point in descending tendency. In the two conditions, the temperature gradients are all becoming smaller. The maximum coupled temperature increases with the increasing of the electric current, and decreases with the increasing of the velocity under the constant displacement and normal force. The maximum coupled temperature increases linearly with the increasing of displacement under constant electric current, velocity and normal force.
