What does a thrust bearing do on a washing machine?
Thrust washers, also known as rotary thrust washers or thrust bearings, are a thin, flat, washer shaped component often made of cast bronze. Commonly used in rotating assemblies, thrust washers support axial loads and are instrumental in keeping components aligned along a shaft.
How important are thrust washers?
They support the axial load or side to side motion on a shaft and prevent movement along that shaft. The thrust washer provides a surface on to which a bearing is supported. They are made to be used in high-wear applications.
What problem do thrust washers prevent?
Thrust washers are flat washers that are located between a rotating surface and a stationary component. They support the axial load or side to side motion on a shaft and prevent movement along that shaft. The thrust washer provides a surface on to which a bearing is supported.
How do I know if my thrust bearing is bad?
A worn thrust bearing has increased clearances between its rollers. This allows the bearing to move around in its seat excessively, which can lead to rattling, squealing or growling noises coming from the transmission. These noises are usually most noticeable when the clutch pedal is pressed down to release the clutch.
What happens when a clutch thrust bearing fails?
Symptoms of a failing clutch thrust bearing: Rattling noise – A worn bearing can produce rattling noises. These noises are most noticeable when the clutch pedal is pressed down. Difficulty changing gears– If the bearing lacks proper lubrication, the clutch may not fully release, resulting in difficulty shifting gears.
What can cause a thrust bearing to fail?
The causes of a thrust bearing failure can be traced to a single problem or a combination of problems. Naturally, improper assembly—se- lecting the wrong thrust bearing thick- ness, contamination during assembly, etc.—can lead directly to thrust bearing failure.
What happens if there is too little thrust clearance?
If there’s too little thrust clearance, the thrust bearing surfaces can’t maintain a sufficient oil film and will overheat and be destroyed, potentially allowing the crankshaft’s main journal fillets to walk into the saddle and cap areas, quickly resulting in severe crank damage.
Where are the thrust bearing flanges located on a motor?
A thrust bearing is either integrated with a specific main bearing assembly or independent of the main journal bearing. If integrated, the thrust bearing area is present in the form of flanges that extend from the front and rear of the main bearing shells.
Why are forward thrust loads increased in automatic transmissions?
Because of the original equipment manufacturers’ efforts to improve fuel economy and minimize noise, vibration and harshness, many automatic transmissions feature increased forward thrust loads that are delivered through the converter.
