Abstract
A device for assembling a railway wheel with brake discs, the brake discs arranged to face each other across a railway wheel web and a center-deviation prevention key penetrating the web, includes a disc support supporting an internal hole of one of the brake discs; a wheel support provided concentrically with the disc support within the disc support, and supporting a hub's bore of the railway wheel on the brake disc supported by the disc support; and a bolt support provided concentrically with the disc support and the wheel support outside of the disc support, and supporting the bolt to correspond to bolt holes formed in the brake discs and the web of the railway wheel. The disc support and the wheel support are individually rotatable about a railway wheel central axis. The disc and wheel supports and the bolt support move up and down relatively to each other.
