ZZ-SERVOLINE® The bevel gearbox range ZZ-Servoline® has been designed as a compact drive unit especially for highly dynamic uses in the automatic control engineering. For the values in the load table a smooth and even servo operation was used. Thereby the transferable performance is limited by the maximum allowable temperature of the housing and the oil bath. If, in continuous operation of the ZZ-Servoline® the rated torque is constant or less, then the serration is permanently fixed. In most applications the gearbox is closed (without pressure compensation) when being used, but with high...

KN0035 TO KN1400 DIMENSIONS K6 (BLOCK- AND ROBOT FLANGE) MOTOR MOUNTING OPTION The mechanical interface of the drive shaft flange corresponds to DIN EN ISO 9409-1 and is designed for the construction of handling devices and exchangeable end effectors with rounded flange. Output shaft (block flange) A single piece flange shaft allows a high torsional rigidity of the drive. Non specified dimensions are according to the dimension sheet “Base Gearboxes”. Input shaft Gear size Housing Dimensions Type In all illustrations the drive shaft with the offset is always at the top Gear Box with Motor Flange...

GEAR BOX WITH MOTOR FLANGE MOUNTING FLANGE DIMENSIONS KN0035 AND KN0070 Due to having a large selection of standard adapter plates, the ZZ-Servoline® can be easily configured for all common servo motors with rectangular flange connections. The main measurements of the flange are listed in the following table of dimensions. Length and diameter of the servo motor shaft must be within the dimensional specifications (w, d). The flange type and the clutch bore (motor shaft diameter) are also defined in the order code for the entire gearbox with motor flange. Dimensions for the gearbox not mentioned...

RADIAL AND AXIAL FORCES TILTING MOMENTS OPERATING MODES The equivalent bearing load is a combination of the gear reactive forces and the outer axial and radial forces on the shaft end. A complete calculation of the bearing service life and the allowable loads is only possible when the application parameters as well as the angle of inclination, the direction of acting forces and the tilting moments are known. Allowable forces and tilting moments k The allowable forces and tilting moments are valid for shaft measurements according to the catalogue. Design Basis: Collective load S5-40%, n2=...

TRANSMISSION PRESELECTION ORDER CODE The gear box preselection can take place according to the following, and should ensure the following three elements: • fulfilment of the drive function • the assurance of the mechanical stability • a suitable thermal design the following information is required: operating conditions, collective load, mode of operation, number and type of gear changes per hour, start up time, duration of load, type of brakes, duration of braking, idle time, running time, duration of standstill and the power requirement. Please state your operating information. We will be...
