Air coupling 500-3

torquefriction

Rotary couplings without/with leakage recirculation Rotary couplings transfer hydraulic oil from a fixed to a rotating machine part. The assembly is done in the rotation axis of the subassembly. Depending on the number of junction levels several single-acting or double-acting hydraulic elements can be connected. On principle, the rotary coupling is only suitable for hydraulic oil. If pneumatic shall be transferred, the catalogued elements can be used providing that the air is filtered and lubricated to guarantee seal greasing and corrosion protection. In the design stage it needs to be considered that the rotation movement is obstructed by the seal friction. This frictional drag is pressure dependant and must be considered for the drive torque of the rotary table. Corresponding information can be found in the reling diagrams which show the starting torques existing while all junction levels are pressurised. Special features: axial and radial connections in the piston available without and with leakage recirculation appropriate for pneumatic and hydraulic systems combinable with multiple coupling systems (KDS) combinable with electrical slip rings as a special design standard designs and special designs available Important operating instruction: For the operating circumstances, operating pressure and torque must be aligned. Please see the diagrams on data sheet 500-3. Mounting instruction: The rotary coupling must be mounted in a way that no transverse moment is effected on the standing or rotating element.
