Abstract
To permit quick mounting and unmounting of a wheel (5) on a balancing machine, and rapid interchange of components of the balancing machine when wheels of different sizes arc, to be balanced, the shaft of the balancing machine has a conical surface (10) formed thereon, or is securely coupled to a first conical part (8), against which a radially expansible second conical part (9) can be engaged. The second conical part (9) has an outer cylindrical surface (12) for clamping in the center hole of a hub or wheel disk or the wheel (5) to be balanced. The second conical part (9) has an axially extending portion (9a), which terminates in a spring abutment (15, 16). A spiral spring (21) is placed around the extending portion, the other end of which engages against a radially directed leg portion (20, 24) of an angle ring (18, 25) which overlaps a radially extending stop (17, 22) formed on the outer conical part (9). The outer conical part (9), thus, together with the spring (21), the angle ring (18, 25) and the spring abutment (15) thereon form a single assembly, from which no parts can be lost or intermingled with parts of different sizes. The radially extending leg (24) of the angle ring…
