Description

Bearing oil seal fixing assembly

Technical Field

The utility model relates to a bearing oil seal, in particular to a bearing oil seal fixing assembly, and belongs to the technical field of bearing oil seals.

Background

Oil seals (oil seals) are a common convention designation for general seals, simply referred to as lubrication seals. It is a mechanical element used to seal grease (oil is the most common liquid substance in transmission systems, also generally referred to as "liquid substance"), which isolates the components of the transmission components that require lubrication from the output components, and does not allow the lubrication to leak. The static seal and the dynamic seal (generally reciprocating motion) are oil sealed by sealing elements.

The general oil seal is only clamped between two collars of the bearing, and a certain gap is reserved because the rotation between the two collars is prevented from being influenced, so that the oil seal is easy to drop downwards and separate from the bearing, and the oil seal is thrown out against the bearing in the process of bearing rotation, so that the normal use of the oil seal is influenced, and therefore, the bearing oil seal fixing assembly is necessary.
