Skeleton oil seal is relatively simple, generally consists of three parts: reinforced skeleton, self-tightening spiral spring, oil seal body three kinds. The sealing body is divided into bottom, waist, cutting edge and sealing lip according to different parts. The skeleton acts as a reinforcing steel bar in a concrete member and allows the oil seal to maintain its shape and tension. Usually, in the free state of the skeleton oil seal, its inner diameter is smaller than the axial diameter, that is, it has a certain "interference". Therefore, when the oil seal is installed on the oil seal seat and shaft, the pressure of the oil seal edge and the contraction force of the self-tightening spiral spring produce a certain radial tightening force on the shaft. After a period of operation, the pressure will rapidly decrease and even disappear. Therefore, the spring can compensate the self-tightening force of the oil seal at any time.
