Deep groove ball bearings are widely used in various industries due to their simplicity, reliability, and versatility. However, the uneven distribution of load within these bearings can lead to premature wear, reduced lifespan, and decreased performance. This article aims to optimize the load distribution in 626 deep groove ball bearings to enhance their performance. The following sections discuss the various aspects of load distribution optimization, including material properties, design parameters, operating conditions, simulation, and experimental validation.
The material properties of deep groove ball bearings play a crucial role in determining their load distribution. The choice of material affects the bearing's hardness, wear resistance, and fatigue life. Table 1 presents the material properties of the 626 deep groove ball bearings used in this study.

| Property | Value |
|---|---|
| Hardness (HRC) | 60-65 |
| Ultimate Tensile Strength (MPa) | 600-700 |
| Wear Resistance (mm³/m) | 0.2-0.3 |

The hardness of the material ensures that the bearing can withstand the applied loads without deforming. The ultimate tensile strength provides resistance to the tensile stresses that may occur during operation. The wear resistance is essential for maintaining the bearing's surface integrity and reducing the risk of wear and tear.
The design parameters of deep groove ball bearings significantly influence their load distribution. These parameters include the bearing's internal geometry, such as the raceway profile, ball diameter, and ball spacing. Table 2 shows the design parameters of the 626 deep groove ball bearings used in this study.

| Parameter | Value |
|---|---|
| Ball Diameter (mm) | 6.35 |
| Ball Spacing (mm) | 0.5 |
| Raceway Profile | Standard |

The ball diameter and spacing determine the bearing's load-carrying capacity and the number of balls that can be accommodated. The raceway profile affects the load distribution and the bearing's running smoothness. By optimizing these design parameters, the load distribution can be improved, leading to enhanced performance.
The operating conditions of deep groove ball bearings, such as temperature, speed, and load, significantly impact their load distribution. High temperatures can lead to material软化 and reduced hardness, while high speeds can increase the risk of ball skidding and wear. Table 3 presents the operating conditions of the 626 deep groove ball bearings used in this study.

| Temperature (°C) | 50-70 |
| Speed (rpm) | 1000-1500 |
| Load (N) | 100-200 |

By optimizing the operating conditions, the load distribution can be improved, leading to enhanced performance and reduced wear.
Simulation is an essential tool for optimizing load distribution in deep groove ball bearings. By using finite element analysis (FEA) and computational fluid dynamics (CFD), engineers can predict the load distribution and identify potential areas of concern. This section discusses the simulation approach used in this study.
The simulation process involved creating a 3D model of the 626 deep groove ball bearing using CAD software. The model was then imported into a FEA software to analyze the load distribution under different operating conditions. The simulation results were used to optimize the bearing's design parameters and operating conditions.
To validate the simulation results, experimental tests were conducted on the optimized 626 deep groove ball bearings. The tests involved measuring the load distribution, wear rate, and lifespan of the bearings under various operating conditions. The experimental results were compared with the simulation results to ensure the accuracy of the optimization process.
This article has discussed the optimization of load distribution in 626 deep groove ball bearings to enhance their performance. By analyzing various factors affecting load distribution, such as material properties, design parameters, and operating conditions, this study has provided insights into improving the efficiency and lifespan of these bearings.
