Oil seal is an important part of various types of agricultural machinery and equipment, and is widely used. Various agricultural machines such as tractors, agricultural vehicles, and rice-wheat combine harvesters are equipped with various oil seals. They can effectively prevent the leakage of lubricating oil and hydraulic oil, and prevent dust and dirt from entering the machine interior. The main factors causing oil leakage in agricultural machinery oil seals: 1. For new or overhauled agricultural machinery, there is no maintenance operation after running-in and running-in in strict accordance with the technical specifications, so that the metal scraps ground inside the machine enter the oil seal and generate abrasives. Wear, resulting in early damage to the seal. 2. Do not pay attention to cleaning when installing the oil seal, so that impurities and dust can enter the oil seal and cause accidental wear of the shaft seal. 3. During installation, the operator clearly knows that there are obvious scratches and burrs on the shaft, and it is still loaded into the machine to pull the oil seal. Or the tightness of the oil and the shaft is not enough, causing the oil seal to leak. 4. The quality of the oil seal is poor, and even the oil seal with obviously incomplete, aged and cracked is installed on the machine, causing oil seal leakage. 5. When the assembly is not properly handled, the oil seal is distorted and deformed. Even the self-tightening spring of the oil seal falls off and causes oil leakage. 6. The tightness of the oil seal self-tightening spring is not enough, so that the oil seal has a poor seal and causes oil leakage. 7. The agricultural machinery is often speeding, and the working speed of the rotary shaft for installing the oil seal exceeds the adaptable speed of the oil seal, resulting in leakage of the oil seal. 8. The installation position of the oil seal on the shaft is not correct. For example, the position of the skeleton self-tightening oil seal and the skeleton rubber oil seal on the drive shaft of the small tractor is opposite, or the opening of the self-tightening oil seal is reversed to cause oil leakage. Also, if the oil seal is installed incorrectly on the shaft, the center line of the oil seal center line and the shaft do not coincide and oil leakage occurs.
