[0002] Skeleton oil seal is a typical representative of oil seal. Generally speaking, oil seal refers to skeleton oil seal. The function of oil seal is generally to isolate the parts of transmission components that need lubrication from the external environment to prevent lubricating oil from leaking. The skeleton is like the steel bar in the concrete component, which plays a reinforcing role and enables the oil seal to maintain its shape and tension. According to the structural form, it can be divided into single-lip skeleton oil seal and double-lip skeleton oil seal. The auxiliary lip of the double-lip skeleton oil seal plays a dustproof role to prevent external dust, impurities, etc. from entering the machine.

[0003] Skeleton oil seal is a typical representative of oil seal. Generally speaking, oil seal refers to skeleton oil seal. At present, some split oil seals or open oil seals launched on the market are made of materials that are too soft and inconvenient to position; some are made of materials that are too hard and the incisions cannot fit tightly. The overall positioning and fitting ability of the existing oil seal skeleton is relatively insufficient. It is not possible to perform self-positioning oil seal adjustment while fitting tightly. The adaptive ability of the oil seal skeleton is relatively insufficient, the convenience of use is not good enough, and the adaptability is insufficient. For this reason, we propose a self-positioning oil seal skeleton with a tighter fit to solve the above problems. Utility Model Content
