Initial Installation Initial Installation Axial runout, radial runout and length tolerances – drive motor The special tolerance for shaft length “L” must be In order to guarantee fault-free operation, the maintained in order to guarantee fault-free motor must not exceed the specified tolerances. gearbox operation.
Initial Installation Balancing Motors with parallel keys are used, which is why the balancing type needs to be noted. The hubs (2) come with a keyway (1) for transmitting power from the motor shaft (3) as standard. There are two balancing types for the motor and gearbox: Semi-key and full-key, which are described in more detail in DIN ISO 8821.
Initial Installation Adaptation, motor/gearbox After cleaning the fitting surfaces, heat the drive The motors must have a flange-mounting option hub to approx. 120 °C from the opening and slide for mounting the gearboxes. it onto the motor shaft until it reaches the stop. The gearbox housing is fitted to the motor by Then check reference dimension “C”.
Initial Installation 4.3.2 Closed design (with shaft sealing ring) In the case of motor adaptation and loosely This variant incorporates an adapter plate (5) with supplied sealing/spacing washers, the latter must shaft seal (7), which means that the gearbox forms be pasted in by means of a jointing compound a compact, closed unit.
Initial Installation 4.3.3 Open design with adapter ring for 2K800, 2K801, 2K1000 and 2K1001 The adapter ring allows adaptation to different connection dimensions. A seal is required on the motor output shaft. The adapter ring (5) and drive hub (1) are delivered loose.
Initial Installation 4.3.4 Open design with adapter ring for 2K802 and 2K1002 The adapter ring allows adaptation to different connection dimensions. A seal is required on the motor output shaft. The adapter ring (5) and drive hub (1) are delivered loose. Clean the fitting surfaces of the motor (3) and drive hub (1).
Initial Installation 4.3.5 Version with pulley drive Gearbox – fit The pulley will be centred on the outer diameter of For drive hub (1) assembly, the M12 threaded pin the drive flange (K6 tolerance), friction-locked in (9) must be screwed in and tightened at the place and secured using screws, whereby the parallel key with 40 Nm until firmly home.

Initial Installation Electrical connection, gear change The electrical connection may only be established During the gear change, the main spindle motor by a qualified electrician. should make the shaft oscillate +5° or -5° at a rate of 1 to 5 rotation direction changes per second. A larger pendulum motion may lead to damage at Risk of damage to shift unit due to incorrect the meshing gears.
