Principle of Operation
The problem of air supply was solved by a stationary distributor
ring with profiled ring seals arranged in it.
Via passage openings in the two elastically radially flexible profile
seals, the compressed air flows via a twin non-return valve to one
of the two pressure chambers. The pilot-controlled non-return
valve controls the feeding into one pressure chamber and the
forced and simultaneous venting of the second pressure chamber.
This triggers the piston stroke and the wedge hooks move the base
jaws. The pressure in the chuck body is shut off and stored by the
valve system (retensioning), while the profile seals are lifted off
the chuck body by their elasticity via the venting of the feed lines
and therefore 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"
