ROTATION WHEEL AND PROJECTION APPARATUS

A rotation wheel, comprising a substrate, a driving assembly, a clamping member and a balancing assembly. The driving assembly is connected with the substrate, and is configured to drive the substrate to rotate around an axis of the driving assembly as the central axis. The clamping member is disposed along the axis on the substrate. The balancing assembly includes at least one balancing material, an adhesive material and at least one channel. The adhesive material encapsulates the balancing material and is filled into the channel to fix the balancing assembly onto the clamping member. The rotation wheel and the projection apparatus of the invention exhibit favorable structural reliability.
