oupling suitable for use in potentially explosive atmospheres. Complies with the current ATEX Directive for: II2GExhIICT6...T5GbX II2DExhIIICT8C...1CDbX IM2ExhMbX Benefits ZAPEX gear couplings link machine shafts and compen- sate for shaft misalignment with weak restorative forces. High transmissible torque combined with compactness and light weight are characteristic of ZAPEX couplings. ZAPEX coupling types are constructed on modular principle. This means that application-specific solutions can be elivered quickly. ZAPEX couplings require very little maintenance. Regular grease or oil changes at the prescribed intervals prolongs the service life of the coupling. Application ZAPEX couplings are especially suited for operation in harsh operating conditions, such as drives in the iron smelting or cement industry. ZAPEX couplings are suitable for reverse operation and horizontal mounting positions and, in the case of type ZWNV, for vertical mounting positions. 4/3 TORSIONALLY RIGID GEAR COUPLINGS | ZAPEX ZW SERIES 4 4 5 5 6 6 7 7 8 8 9 9 1 1 1 1 1 1 1 1 GENERAL Design and configurations ZAPEX coupling comprises two hub sections with external teeth which are mounted on the machine shafts. Each set of external teeth engages in flanged socket with mating internal teeth. The flanged sleeves are connected via two flanges with close-fitting bolts. The teeth are lubricated with oil or grease. On the ZAPEX type ZW, DUO sealing rings are used to seal the tooth space. The DUO sealing rings prevent the lubricant from escaping and dirt from entering the tooth space. The parallel keyways must be sealed during assembly to prevent lubricant from escaping.Customized hub designs are described after the types.Type Description ZWN Standard type ZZS with adapter ZZW with intermediate shaft ZWH with coupling sleeve ZWBT with offset brake disk ZWBG with straight brake disk ZWB with brake drum ZWTR for rope drums ZBR with shear pins ZWS Clutch ZWNV Vertical type ZWSE
