Problems solved by technology

Once the transmission gear set is worn out, the transmission gear set will slip teeth. Although the motor shaft will not move due to the braking of the brake disc, the door curtain will fall due to its own weight, and people and objects will be injured. There are many potential safety hazards.

Abstract

The invention mainly relates to the technical field of roller shutter doors, in particular to an electric roller shutter door. A metal brake disc is mounted at one end of a drum of the roller shutterdoor, the metal brake disc is braked through an electric braking device of a side board assembly, even when a door roller gear set is subjected to abrasion and slippage or a transmission chain of a transmission support plate is broken, accidental falling of the roller shutter door can be avoided, and the safety of the roller shutter door is improved.

Description

technical field [0001] The invention relates to the technical field of rolling doors, in particular to an electric rolling door. Background technique [0002] Now factories, stores, shopping malls, fire exits, garages and other places are equipped with electric rolling shutter doors. The electric rolling shutter door is driven by the rolling door machine, rolling the reel and driving the door curtain to lift. At the same time, the rolling door machine must be braked through the braking system, otherwise the rolling door will fall down due to the weight of the rolling door itself, so in the braking system of the rolling door machine, the brake disc is the most critical safety part, and all the braking effects are good. Bad is that the brake disc plays a decisive role; but the brake disc of the existing rolling door machine is installed on one end of the motor shaft, and the other end of the motor shaft is meshed with the transmission gear set of the gearbox. Make the motor r...
