Introduction

The skeleton oil seal structure consists of three parts: an oil seal body, a reinforced skeleton and a self-tightening coil spring. The sealing body is divided into bottom, waist, cutting edge and sealing lip according to different parts. Generally, the skeleton oil seal in a free state has an inner diameter smaller than the outer diameter, that is, it has a certain "interference amount".

Therefore, after the oil is encapsulated in the oil seal seat and the shaft, the pressure of the oil seal blade and the contraction force of the capital coil spring produce a certain radial tight force on the shaft. After a period of operation, the pressure will quickly decrease or disappear. Therefore, the spring can compensate the self-tightening force of the oil seal at any time.

The role of the skeleton oil seal is generally to isolate the components that need to be lubricated from the output components in the transmission components. Do not let the lubricant leak. Commonly used for rotary shaft is a rotary shaft lip seal.
