A torque limiting coupling for a hoisting machine
The invention relates to a torque limiting coupling for a traction sheave of a hoisting machine such as an elevator. The torque limiting coupling comprises a traction sheave (140, 240) and a brake wheel (101, 201). The brake wheel has a friction surface (136, 138, 268) arranged to be in contact with...

| Zusammenfassung: | The invention relates to a torque limiting coupling for a traction sheave of a hoisting machine such as an elevator. The torque limiting coupling comprises a traction sheave (140, 240) and a brake wheel (101, 201). The brake wheel has a friction surface (136, 138, 268) arranged to be in contact with a traction sheave (140, 240) of a hoisting machine. The friction surface (136, 138, 268) allows a friction limited rotation of the traction sheave (140, 240). |
