TSCHAN® TNT 2420

  • TSCHAN heavy load couplings in the TNT series are specially designed for overload protection in the heavy load industry. The heart of the couplings is in the standardised switching units, up to twelve of which are located around the circumference of the coupling. This achieves great flexibility with regard to disengagement torque, execution and coupling size.

    Operation

  • The switching units (1) create the connection and the torque transmission between the drive side (2) and the output end (3) of the coupling. To do this, steel balls (4) are pressed by spring force (5) into a conical resting position (6). If the axial force that is created in the event of overload exceeds the disengagement torque set on the switching units then the steel balls come out of their resting position and cause a constant activation or a separation of the two halves of the coupling. In this condition the coupling is disengaged and free running of the coupling is ensured. After disengagement the coupling can be returned to its operating condition by striking the pressure pin (7) with a rubber or plastic hammer. It is possible to adjust the disengagement torque in each setting range. We would be pleased to send you our setting chart on request.
  • Mechanical limit switch

  • The TNT series can also be adapted with an optional dial and mechanical limit switch on the motor side. These switch signals can be used to switch off the drive and send out an acoustical or optical signal at the same time.
  • The great flexibility of TSCHAN TNT heavy load couplings means that solutions can also be carried out beyond standard products.
