Start-Up Of Linear Axis - NTN-SNR LINEAR AXIS AXC Series Manual

3.5

Start-up of Linear Axis

Linear Axis can travel at high velocity with a large degree of force. Slider fittings can lead to bodily injury or material damage upon
collision. Start-up should thus be performed with the utmost caution.
Furthermore, it should be ensured upon start-up that the permissible loads are not exceeded and the slider fittings are securely
fastened. It should also be ensured that the maximum possible travel distance is not exceeded. If travel distance is limited with limit
switches, they should be previously tested in terms of performance and correct positioning.
Hazards can arise through unintentional descending of vertical Linear Axis. The end user must take the necessary precautions. We
recommend to use the Fachausschuss information sheet Nr. 005 „ Gravity-loaded axis (Vertical axis)" issue 02/2004 from Fachausschuss
Maschinenbau, Fertigungssysteme, Stahlbau (Germany).
The manufacturer is not liable for damages resulting from non-observance of these start-up instructions. The user bears
sole responsibility for all risks.
3.6 Assembly of couplings on Linear Axis with toothed belt drive
The assembling of couplings on Linear Axis with toothed belt drive is carried out according to the following steps (Figure 3.9):
1. The coupling hub with feather key
already screwed in the hollow shaft of the
Linear Axis by the fastening screws
and equipped with the elastomeric gear rim
on delivery.

2. The axis side coupling hub will be
optionally combined with clamping hub
and clamping screw
4
feather key or with tension ring hub
The screws must be installed with the
tightening torque from Table 3.3.
3. For parallel Linear Axis with connecting shaft,
a half-shell clamping hub
allow a later mounting and dismounting of
the connection shaft.
