ZOLLERN Slewing Units have proved highly successful under extrme operating conditions. Their principal features and most significant advantages are compact dimensions ꕕ ease of maintenance long operation life ^ high performance Օ modular design of gear unit functional design With these characteristics the machine designer will get a ready to install unit and will achieve economic solutions even in confined space conditions. Potential applications Օ mobile cranes material and working elevators Օ shipboard and deck cranes dockyard and harbour cranes Օ container gantries yaw & pitch...

FEATURES AND DESIGN Coaxial design Three planetary stages Ratios i = 46 to 148 Drive by electric motor Long output shaft Fastening by reaction torque arm Input shaft and output shaft have the same direction of rotation Coaxial design Three planetary stages Ratios i = 46 to 148 Drive by electric motor Short output shaft Input shaft and output shaft have the same direction of rotation. Slewing Unit Output torques from 1400 to 1550000 Nm Ratios i = 14 to 1007 (other ratios available on request). When determining the torque, the acceleration and the deceleration as well as wind effect and other...

Lubrication All gears and anti-friction bearings are splash lubricated. Output bearings are grease packed for lifetime operation -requiring no further service attention. Service intervals and recommended lubricants are given in the table on page 15. Oil level is checked by either dip stick or sight glass. Oil outlet Oil outlet Oil outlet 4 5 Coaxial design Three planetary stages Ratios i = 46 to 148 Drive by hydraulic motor Long output shaft Input shaft and output shaft have the same direction of rotation. Coaxial design Two planetary stages Ratios i = 14 to 30 Drive by hydraulic motor...

Seals The input is sealed by a radial shaft sealing ring with a dust lip a) by two radial shaft sealing rings b) by the grease packing in the output shaft housing c) by another radial shaft sealing ring so that safe protection against oil loss and against penetration of dirt and water is assured. Input Options ZOLLERN's modular system provides for hydraulic or electric motor input interfaces. Flange mounted or free shaft with key to DIN 5480. Parking brake Amply dimensioned spring-applied multi-disc parking-brake, hydraulically released, to hold the slewing mass and to brake the slewing...

Output Pinion Options Forged one pice pinion shaft - standard Splined Output Shaft Pinion fitted with splines to DIN 5480. Output Pinion Specification Tough 42CrMo4V hardened gear steel tempered to 700-900 N/mm2 Teeth surface hardened HRC 57+7 (Case hardened Pinions with ground gearing available on request) Selection of gear unit size In order to determine the correct gear unit for a given application, the output torque Tdyn has to be multiplied with the factor k, page 9. Working conditions The slewing gears are designed for operation in European conditions or similar. Permissible oil...

GEAR UNIT SELECTION Dtermination of the imposed maximum torques on the output pinion of the slewing gear unit can only be undertaken with the exact knowledge of the general view. The following has to be considered acc. to section 1,3rd dition 1998 SMF = maximum torque due to frictional forces SMA = maximum torque due to acceleration SMW8 = maximum torque due to wind effect 80 N/m2 SMW25 = maximum torque due to wind effect 250 N/m2 SMS = maximum torque due to inclined position ym = amplifying coefficient of loading depending on mechanism group factor Regular service without wind effect SM...
