Patent ID: 8263021

Claim:
A rotating mechanism for rotationally driving a direct-heating reaction disc, comprising; a fixed hollow shaft; a rotating sleeve assembly; and a signal commutator, wherein the fixed hollow shaft is fixed and is disposed in the rotating sleeve assembly, the signal commutator is disposed inside the rotating sleeve assembly and has a stationary end fixedly attached to the fixed hollow shaft and a moving end rotating with the rotating sleeve assembly, a driven member is mounted to the moving end of the signal commutator, and a notched portion is formed through the rotating sleeve assembly in a position corresponding to the driven member, with the driven member extending into a rotating path of the notched portion, such that when the rotating sleeve assembly is rotated, the notched portion abuts against the driven member to drive the driven member and the moving end of the signal commutator to rotate, and the rotating sleeve assembly comprises a first rotating sleeve and a second rotating sleeve fixedly connected to each other, in which the fixed hollow shaft is fitted in the first rotating sleeve by one or more bearings, a bottom end of the second rotating sleeve is fixed to a top end of the first rotating sleeve, a top end of the second rotating sleeve is fixed to a reaction disc, and the notched portion is provided in the second rotating sleeve.
