The stress and strain on the surfaces of a rolling bearing has an important significance in bearing lifespan estimate, fault analysis, and stiffness calculation. Aimed at the contact problem of a deep groove ball bearing based on ANSYS, this paper mainly discusses three technologies, viz., parameterized modeling technology, division technology, and meshing technology, to provide a new method for setting the contact parameters in the process of finite-element analysis. The result shows that the method proposed in this paper is practicable, only with a small error relative to the Hertzian theory.

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.

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. The rolling bearings used in this study are deep groove ball bearing type 6003 RS with internal diameter (d) = 17 mm, outer diameter (D) = 35 mm, bearing thickness (B) = 10, number of rolling elements (Nb) = 10 pieces, and the diameter of the rolling element (Bd) = 4.75 mm. In the rotation of the bearing (Fr) = 2003 rpm (33.38 Hz) we found the experimental results of bearings that have been damaged in the outer race at 138 Hz frequency, inner race damage at 196 Hz frequency, (ball) at a frequency of 88.8 Hz and cage damage at a frequency of 13.8 Hz.

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.

Slight Deformation

This paper presents a comprehensive analysis of the assembly processes for single-row ball bearings. There are two different types of assembly processes, which depend on ball numbers and ball bearing ring designs. In the case of deep groove ball bearings, assembly is usually undertaken through slight deformation of the outer ring to increase clearance for insertion of the final ball. As a result, the outer ring takes an elliptical instead of a circular shape and requires deformation to be below a critical level to avoid fracture. Causal analysis of outer ring fracture during assembly is the main goal of the presented analysis, based on the expressions of the Theory of Elasticity for the thin ring exposed to bending, as well as Finite Element Analysis (FEA). The theoretical and numerical results have been verified by experimental testing.

Non Linear

This article presents a non-linear model of deep groove ball bearing and results of simulation. Vibrations of this bearing are studied for a wide range of clearance. An evolution from periodic to chaotic vibrations is visible due to increase of clearance. A number of phenomena associated with non-linear dynamics are observed, for instance: bistability, chaotic vibrations, windows of periodical vibrations, jump of amplitude, period-doubling cascade leading to chaos, bifurcation directly leading to chaos, and self-similarity of a Poincaré section. Moreover, amplitudes of vibrations are presented as functions of clearance. This provides an opportunity to select failure modes. Unfortunately, relations clearance amplitude and amplitude - clearance are ambiguous.

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.
