ABSTRACT:
The bolt-together wheel consists of a pair of side plates separated from one another by cylindrical spacers. The spacers are connected to the side plates by shearable bolts where the head of the bolt will shear off when a predetermined torque is applied thereto. The predetermined torque is selected such that the bolt head will shear after the bolt securely fixes the spacers to the side plates. As a result, the bolt does not extend from the side plate such that wear on the blast wheel is reduced. After the bolt head shears, it can be machined to provide a uniform, smooth surface that further minimizes wear. Finally, the edges of the side plates can be provided with tapered faces to reduce the impact force of rebounding shot and the wear resulting therefrom and to direct the rebounding shot away from the interior of the blast wheel.
