Construction of Buy skeleton oil seal products

2022-03-18

Generally speaking, the oil seal refers to the Buy skeleton oil seal products. The function of the oil seal is generally to isolate the parts that need to be lubricated in the transmission parts from the external environment, so as not to let the lubricating oil leak. The skeleton is like the steel bars in the concrete member, which acts as a reinforcement and enables the oil seal to maintain its shape and tension. According to the structure, it can be divided into single lip and double lip. The auxiliary lip of the double lip acts as a dustproof, preventing external dust, impurities, etc. from entering the inside of the machine. Let's take a look at its structural knowledge!


The structure of Buy skeleton oil seal products consists of three parts: oil seal body, reinforcing skeleton and self-tightening coil spring. The sealing body is divided into bottom, waist, cutting edge and sealing lip according to different parts. Generally, the inner diameter of the Buy skeleton oil seal products in the free state is smaller than the shaft diameter, that is, there is a certain "interference".
Therefore, after the oil seal is installed on the oil seal seat and the shaft, the pressure of the oil seal edge and the contraction force of the self-tightening coil spring will generate a certain radial tightening force on the shaft. After a period of operation, the pressure will rapidly decrease or even disappear. , Therefore, adding a spring can compensate the self-tightening force of the oil seal at any time.
