6.2.3.1 Version ZS and ZT – Plug-in planetary gearbox
The versions ZS and ZT represent the simplest versions of the mounting of a planetary gearbox at NTN-SNR Linear Axis with toothed
belt drive of the series AXC. Here, the gearbox shaft with feather key is form-fitted inserted positively into the hollow shaft of the drive
pulley. This version is suitable for applications with low dynamics and low alternating loads such as for vertical applications. By the
direct mounting account coupling cone, plug-in shaft and coupling, thus resulting in extremely compact dimensions and in addition
in a reduction of the moment of inertia and thus in a reduction of the drive torque.
Table 6.17 contains the code numbers for the type code and the dimensions of the adaptations of the planetary gearboxes.
