Abstract: In this study, we identified the noise generated from automotive wheel bearings, which has recently emerged as a new problem in electric vehicles. The wheel bearing assembly considered in this study consists of a wheel bearing, dust shield, and knuckle, which are fastened with bolts. To obtain the noise characteristics of the wheel bearing, the noise and vibration were experimentally measured when the bearing rotated. Additionally, the natural frequencies and mode shapes of the main components of the bearing were acquired via modal testing. By comparing the obtained natural frequencies with the peak frequencies of the measured noise and vibration signals, we identified where the noise radiated. To specifically identify bearing defects, a finite element analysis model was established, and the deformation of the bearing under load was analyzed. Based on the analysis, we determined that the deformation of the outer ring in an outboard row, which resulted from bolt fastening, leads to noise and vibration in the wheel bearing. Keywords: automotive wheel bearing; noise and vibration; bearing defect; radial deformation

Thrust Ball Bearings are bearings that use spherical balls as rolling elements. They are composed of one or more spherical balls positioned within the bearing housing. Thrust ball bearings are typically used in low-speed applications and can handle small to medium axial loads. They offer advantages such as compact structure, easy assembly, and low cost. Common applications include automotive transmissions, fans, and household appliances.

A sleeve bearing (also known as a bushing bearing or plain bearing) is a straightforward and fundamental type of bearing. It primarily consists of an inner metal sleeve (known as the bushing) and an outer metal sleeve. Between these two sleeves lies a layer of special lubricating material, typically a sliding surface coated with grease or oil.

Thrust ball bearings, is a common type of ball bearing that differs from other ball bearings in that it doesn't have an inner and outer ring. Instead, it uses washers to replace them. This design makes thrust ball bearings more suitable for applications with limited space or restricted axial mounting positions.

Thrust ball bearings are composed of balls and two washers, the balls serve as the main load-carrying components and roll on the washers. The washers are usually made of metal and have specific groove shapes to accommodate the movement of the balls. One of the washers is called the upper washer, and the other is called the lower washer. The gap between the upper and lower washers allows the balls to move in the axial direction.

Electric Motor Bearings: In electric motor and compressor equipment, thrust ball bearings provide axial support to ensure smooth operation of rotating components.

Agricultural Machinery Bearings: In agricultural machinery equipment such as tractors, harvesters, and irrigation devices, thrust ball bearings can withstand soil pressure and axial loads to ensure the normal operation of the machinery during agricultural operations.

It is commonly referred to as "bearing" in English, while in Taiwan, it is usually called "軸承". The fundamental principle of a bearing involves the placement of rolling elements, such as balls, needles, or rollers, between the inner and outer rings to facilitate smooth rotation of the shaft.

Thrust ball bearings have smaller installation space requirements and offer flexibility, making them vital components in many mechanical devices. They are commonly found in applications such as automotive transmissions, clutches, engines, and industrial machinery. Since they don't have inner and outer rings, the selection and installation of washers are crucial for ensuring the proper operation of the bearings.

In this article, we will explore the significance of the ball bearing size chart and understand how to interpret and utilize it effectively.

In summary, thrust ball bearings use washers instead of inner and outer rings, providing smaller installation space requirements and flexibility. They are important bearings for withstanding axial loads and are commonly used in various mechanical devices. When using thrust ball bearings, it is important to select and install the washers correctly to ensure smooth transmission and support of the axial load. Additionally, proper lubrication and maintenance of the washers should be observed to prolong the bearing's lifespan and ensure reliable operation.
