Abstract
A coupling system between an operating machine and a planetary gearbox. The coupling system comprising an axially rotatable machine shaft of an operating machine; and a slow gearbox shaft of a planetary gearbox connectable integrally in rotation with the machine shaft in an operational configuration. The machine shaft and the slow gearbox shaft comprise a first coupling portion and a second coupling portion, respectively, substantially truncated cone-shaped and complementary to each other, the first coupling portion and the second coupling portion being conically coupled to each other in the operational configuration.

A coupling system comprising:
- at least one axially rotatable machine shaft of an operating machine;
- and
- at least one slow gearbox shaft of a planetary gearbox connectable integrally in rotation with said machine shaft in an operational configuration;
- wherein
- wherein said machine shaft and said slow gearbox shaft comprise at least one first coupling portion and at least one second coupling portion, respectively, substantially truncated cone-shaped and complementary to each other, said first coupling portion and said second coupling portion being conically coupled to each other in said operational configuration;
- kinematic constraining means associated with said machine shaft and with said slow gearbox shaft adapted to integrally constrain the latter to each other;
- wherein said constraining means comprise axial constraining means of the relative axial sliding of said machine shaft with respect to said slow gearbox shaft, and
- wherein said constraining means of the relative sliding comprise:
- at least one first ring nut associable with said machine shaft:
- at least one second ring nut associable with said slow gearbox shaft;
- and
- fastening means coupleable in the operational configuration to said first ring nut and to said second ring nut to rigidly fix them to each other.
A system comprising:
- a coupling system;
- an operating machine;
- and
- a planetary gearbox, wherein
- the coupling system is located between the operating machine and the planetary gearbox,
- at least one axially rotatable machine shaft of an operating machine;
- and
- at least one slow gearbox shaft of a planetary gearbox connectable integrally in rotation with said machine shaft in an operational configuration;
- wherein
- wherein said machine shaft and said slow gearbox shaft comprise at least one first coupling portion and at least one second coupling portion, respectively, substantially truncated cone-shaped and complementary to each other, said first coupling portion and said second coupling portion being conically coupled to each other in said operational configuration;
- kinematic constraining means associated with said machine shaft and with said slow gearbox shaft adapted to integrally constrain the latter to each other;
- wherein said constraining means comprise axial constraining means of the relative axial sliding of said machine shaft with respect to said slow gearbox shaft, and
- wherein said constraining means of the relative sliding comprise:
- at least one first ring nut associable with said machine shaft;
- at least one second ring nut associable with said slow gearbox shaft;
- and
- fastening means coupleable in the operational configuration to said first ring nut and to said second ring nut to rigidly fix them to each other.
