Abstract
A connecting arrangement for rotor blades of a turbomachine includes projections (), which extend in circumferential direction (), are rigidly connected in pairs to a rotor blade and are respectively supported on the adjacent projection () by means of a pressure body (). Each pressure body () has, on a securing face (), a securing contour () which protrudes into an acceptance feature () of the associated projection () and is supported in it. Each pressure body () has, on a support face (), a plane support surface () which has area support on a plane mating support surface () of the adjacent projection (). In order to also improve the support in the case of different rotational angles of the projections (), the securing contour () of the pressure body () is configured as a spherical segment. The associated acceptance feature () is likewise configured as a spherical segment whose radius (R) is of the same magnitude as the radius (R) of the spherical segment of the securing contour ().
