Abstract
Drive coupling assembly () for a high-speed rotating brush, comprising:—a coupling head () having a coupling head rotation axis (L) and including three drive surfaces () which are arranged to be rotationally symmetrical through 120° with respect to said coupling head rotation axis; and—a coupling member (), having a coupling member rotation axis (L) and including three first drive surfaces () which are arranged to be rotationally symmetrical through 120° with respect to said coupling member rotation axis, wherein said coupling head () and said coupling member () are detachably couplable, such that, in a coupled condition, their rotational axes (L, L) are aligned and the coupling head is rotatable to drive each of its drive surfaces () in contact with a respective first drive surface () of the coupling member, to thereby exert both a torque and an axially directed force on the coupling member.
