6.2 Safety nut (wear monitoring)
1 Visual wear monitoring
2 Inductive sensor
3 Pulse recession
4 Guide ring
5 Tube cab
6 Nut breakage limit switch
7 Travelling nut
8 Safety nut
Principle: With further wear, the gap X diminishes (documentation see 9.2.6)
Once the wear limit has been reached, the safety limit switch is activated.
The switch signals should be processed by the controller according to the requirements of the respective product
standards.
Only possible with trapezoidal thread spindles or buttress thread screws.
6.3 Safety-trap nut (option for ball screw spindles)
If the ball screw nut malfunctions, the ball screw spindle catches on the thread of the trap nut.
As a result, the power requirement of the drive motors increases. The unit needs to be
switched off by the controller or otherwise by a load monitor.
6.4 Options for screw jacks Ba1 and Ba2
6.4.1 Protection against skimming "Se", "Ve";
The end stop is a safety device and should not be used as a "working stop". If the end stop is run against
the block, this can cause damages to the screw or gears.
6.4.2 Ball thread spindle “Ku”
Please note during assembly and transport. Ball thread spindles are not self-locking.
Driving only permitted with a brake motor.
6.4.3 Multi-geared trapezoidal thread screws
Please note during assembly and transport. Multi-geared trapezoidal screw are not self-locking.
Driving only permitted with a brake motor.
6.4.4 Buttress thread screws "S"
Only in combination with 2 guide rings.
7 Assembly
Inspecting the used screw jacks for compliance with the technical requirements.
Add-on construction, supporting structure and groundwork is designed for the maximum forces.
For screw torques, see 7.11
Protect screws from soiling during transport, assembly, construction and storage.
Screws need to be protected during operation against soiling, e.g. by bellows, coils or on-site covers.
On worm gear screw jacks with oil lubrication, check the oil level, refill if necessary, insert bleed plug, pull
pin at bleed plug.
If necessary, mount and set limit switch.
Avoid misalignment and angular offset.
Provide movable load support points if necessary.
Distortions increase power consumption and reduce the service life!
Carry out assembly and run-in phase without explosive atmosphere.
The ATEX marking on the incorporated components must correspond to the existing
ATEX atmosphere.
