Version Ze And Zp - Integrated Planetary Gearbox - NTN-SNR LINEAR AXIS AXC Series Manual

6.2.3.2 Version ZE and ZP - Integrated planetary gearbox

NTN-SNR Linear Axis of the series AXC, AXF (Figure 6.29), AXDL (Figure 6.30) and AXS280Y could be equiped with an integrated
planetary gearbox. By the direct mounting account coupling cone, plug-in shaft and coupling, thus resulting in extremely compact
dimensions. The use of integrated planetary gearboxes results in addition in a reuction of the moment of inertia and thus in a reduction
of the drive torque.

Depending on series and size different versions of integrated planetary gearboxes are available.
Version ZE
In the version ZE drive pulley is force-fitted mounted by clamping ring hub on the smooth motor shaft, which ensures a backlash-free
torque transmission. In use are spur-toothed planetary gearboxes with low backlash. This version represents a cost effective solution,
which is particularly suitable for applications with high demands on the dynamics. It is to be taken into account that the noise emission
of these gearbox versions is approx. 6 dB higher than the ZP version.
Version ZP
The version ZP has an identical configuration to the version ZE. In use here are planetary gearbox with helical gearing and reduced
backlash. This variant is particularly suitable for applications with highest demands on noise emissions, dynamics, drive torque and
precision.
Table 6.17 in Chapter 6.2.3.1 contains the code numbers for the type code and the dimensions of the adaptations of the planetary
gearboxes.
Tables 6.19 and 6.20 contain technical datas and dimensions (Figure 6.31 and 6.32) of the gearbox versions.
