Air transmission system
Air transmission
The air is only transmitted when the lathe spindle is at a standstill
via profile seals arranged radially in the distributor ring. The profile
seal is designed in such a way that the outer upper surface part is
larger than the surface of the passage openings. When pressure is
applied, the difference in area in the annular chamber of the
distributor ring results in a radial force on the profile seal, which
provides an optimum static seal of the profile seal at the air
transfer interface. The air can thus flow into the cylinder chamber
of the chuck through the passage openings in the profile seal with
low loss.
When the compressed air supply is stopped, the double check
valve closes and the pretensioned profile seal lifts itself off the
chuck body again due to its elasticity and cannot wear out while
the chuck is rotating.
NOTE:
The venting is diverted to the outside by a quick venting function
directly via sound absorbers. This significantly reduces clamping
times and noise development. On the ROTA TB2 600 (LH) to ROTA
TB2 1000 (LH) chucks, the double check valve is integrated in one
insert (see chapter drawings "Valve insert"
