Sun gear fixing bolt for Demag AC80-1

The sun gear fixing bolt is a specialized fastener engineered to secure the sun gear within the planetary gear assembly of the transmission system. It ensures that the sun gear remains correctly positioned during operation, facilitating the transfer of torque through the gear train of the Demag AC80-1 crane.

This component, identified by part number 319 302 99, is manufactured for specific fitment on the Demag AC80-1 model. Proper installation of this fastener maintains the alignment of the planetary gear set, which is necessary for the mechanical function of the crane transmission and movement systems.

In planetary gear systems, the sun gear acts as the central input or output member. Fixing bolts of this type are used to lock the gear in place relative to its carrier or housing, preventing axial or radial displacement under load. By maintaining this connection, the bolt allows the transmission to handle rotational forces effectively.
