Abstract
The invention provides a transmission device of an industrial door opener capable of automatic switching. The invention mainly aims to provide a two-way lead cam and a critical fixing device, wherein the two-way lead cam is fixed in axial direction and does not rotate in an initial state under the action of the critical fixing device; when a hand-pulled chain wheel fixed on the same mandrel along with the two-way lead cam is pulled in random directions, a part A can slide from a low point to the highest point of a spiral surface or a thread groove; thus, the mandrel moves in axial direction towards the same direction and cooperates with a bevel gear pair and a power supply switch to switch motor drive to manual drive flexibly; and when a hand-pulled chain is loosened, motor drive is switched back under the action of a mandrel restore device.
