Protector for sealed joint between fixed and rotary transmission components has deflector moving between assembly and operating positions

摘要

The protector consists of a seal (5) associated with a deflector (6) moving between assembly and operating positions. In the assembly position the deflector is fitted with its edge inserted into the seal and an inner protective sector (12) inside the seal's flexible lip. When the rotary component (shaft) is inserted through the joint the deflector moves away from the seal so that the seal lip makes contact with the shaft.
