The use of this non-destructive coupling system is recommended when the highest demands are placed on the shutdown accuracy in connection with a quick restart. They are used, for example, on conveyor belt drives in opencast mines, pump applications, in steelworks and paper mills, as well as on crushers, to name just a few examples. The AUTOGARD series 400 torque limiter is characterized by the fact that this safety clutch goes into freewheeling mode in the event of an overload, relieving the load. To re-engage, one side of the clutch is reversed by a maximum of one revolution at low speed. This can also be done by controlling the drive motor, so that you may not have to tamper with the safety coupling directly. The AUTOGARD series 400 safety couplings are available in different versions: Model 402: for direct assembly of drive elements such as chain wheels, belt pulleys or similar Model 403: with universal mounting flange, e.g. for cardan shaft mounting Model 405: with flanged metal disc coupling, single or double Cardanic model 406: with flanged elastic coupling In addition to the various mounting options, the safety coupling can be designed with synchronous re-engagement (SR) or with unsynchronous re-engagement (RR). The SR variant is selected for high speeds that require balancing of the torque limiter and for drive systems that require phase-accurate torque transmission. Where the phase-precise re-engagement is not important, the RR variant is selected, which re-engages in a 60 ° pitch. Ask us, we have a solution for most applications!3D-Stp-files are available on request

For the direct assembling of belt pulleys or gears. The add-on parts are slide-mounted on the coupling hub, the slide bearing is included in the delivery, but must be shortened to the appropriate length on site. There are threaded holes in the adapter plate for attachment to the coupling.

The 405 series has a flange-mounted Thomas metal disc coupling. The variants XTSRS for single cardanic compensation and XTSR52 for double cardanic compensation are available here.
