  • connection members Due to the rotational movement of the drum, forces act in the radial and axial directions onto the connection members that connect the spider arms with the sheet metal and the rear cover. Due to the acting forces, the connection members are deformed in the course of time, risking the detachment of the spider arms from the drum.
