Skeleton Oil Seal package with precautions
First, receive a fixed number of seals.
Second, from the oil seal to the assembly, must be kept clean.
Third, before assembly, do a good job in oil seal inspection, measure the size of each part of the oil seal is consistent with the size of the shaft and cavity. Before the oil seal is installed, the size of the shaft diameter should be clearly compared with the inner diameter of the oil seal. The size of the cavity should be suitable for the width of the outer diameter of the oil seal. Check whether there is any damage or deformation to the lip of the oil seal, whether the spring has fallen off or rust. To prevent the oil seal from being laid flat in the middle of the transportation process and being affected by external forces such as extrusion and impact, and destroying its roundness.
Fourth, do a good job before the assembly of machining inspection procedures. Volume and size of the cavity and the parts are correct. Especially the inner chamfer. Can not have a slope. Shaft and cavity end surface processing should be smooth, chamfer no damage and burrs, clean Assembly site, in the axis of the loading (chamfer) part can not have burrs, sand, iron and other debris, will produce oil seal lip irregular damage, it is recommended that chamfered parts using r angle.
Fifth, in terms of operating skills, you can feel it with your hands, whether it is smooth and round.
6. Do not tear the wrapper too early before installing the oil seal to prevent debris from adhering to the surface of the seal and bring it into operation.
7. Before installation, the oil seal shall be coated with lithium-based ester added with molybdenum disulfide in a proper amount between the lips to prevent dry grinding of the lip when the shaft starts instantaneously, which affects the amount of interference of the lip and should be As soon as possible, assembly. If the oil seal is installed, if it is not installed immediately, it is recommended to cover it with a cloth to prevent foreign matter from adhering to the oil seal. Lithium grease hand or tool must be clean.
Eight, the oil seal must be flat and it must not be tilted. It is recommended to install using hydraulic equipment or sleeve tools. The pressure should not be too great; the speed should be even and slow.
Nine, for the machine mounted oil seal this time, make a mark to facilitate tracking, pay attention to the entire process.
