'V' Rings
‘V’-Rings are made
entirely of rubber, and can therefore be stretched over fittings, flanges
or other obstacles. They comprise a body and a joined conical lip. The
‘V’-Ring is mounted on and rotates with the shaft, with the lip
sealing against the housing, and the body holding it in position as well
as sealing against the shaft.
Advantages
- Each type of ‘V’-Ring can be used for different shaft diameters because of their elasticity.
- Because of the rotation of the
‘V’-Ring, the seal can act as both a lip seal and deflector of
liquids, greases, oils, dirt, sand and other materials.
- It can accommodate for shaft abnormality and misalignment.
- ‘V’-Rings can withstand both axial and radial loading.
- The demands of the ‘V’-Ring on the tolerances and surface finish of the sealing surfaces are minimal.
- The ‘V’-Rings will not wear the shaft, which is the expensive part of the machine.
- No special requirements are necessary concerning the machining of the shaft.
- Because the ‘V’-Ring can be mounted directly on to the shaft, it can be easily changed without time-consuming disassembly.
- Complicated designs can be avoided, because the designer can adapt the ‘V’-Ring to the design instead of vice-versa
