As shown in fig. 5, the magnet mounting bracket is formed by stacking and gluing silicon steel sheets.

The driving long shaft is provided with a plurality of torque transmission devices, and the torque transmission devices are synchronously driven by the driving long shaft to jointly realize material transmission of the roller way conveying line.

The working principle of the magnetic damping transmission device for the friction roller way conveying line is as follows:

the driving bevel gear is installed on the torque transmission device, torque transmission is achieved through magnetic attraction between the hollow shaft and the end cover provided with the driving bevel gear in the torque transmission device, the torque transmission part is in a non-contact mode, when the conveyor line material tray is stopped, the torque limiting device can enable the driving long shaft and the driving bevel gear to be separated from transmission, and the problem of abrasion cannot exist even after long-term use.

The working process of the magnetic damping transmission device for the friction roller way conveying line is as follows:

the torque transmission device 1-3 is fixed on the driving long shaft 1-2 through a hollow shaft of the torque transmission device, four magnets are fixed on the torque transmission device through a magnet mounting frame 2-7, and the front end cover 2-4 is connected with the hollow shaft through a bearing 2-2, so that the front end cover can rotate coaxially with the hollow shaft. The front end cover is in threaded connection with the rear end cover 2-5, the iron ring 2-6 is in interference fit with the rear end cover, and the front end cover, the rear end cover, the iron ring and the iron ring can synchronously rotate. The magnetic attraction force exists between the magnet and the iron rings 2-6, so that the hollow shaft and the front end cover can rotate when the driving long shaft rotates. Because the driving bevel gear 1-4 is arranged on the front end cover of the torque transmission device and is not contacted with the driving long shaft, the driving bevel gear rotates under the driving of the torque transmission device and drives the driven bevel gear meshed with the driving bevel gear to rotate, and the driven bevel gear and the driven shaft 1-5 drive the roller 1-8 to rotate, thereby realizing the material conveying of the conveying line.

When the material tray stops, the roller still has the trend of continuing to rotate under the drive of the transmission device, but because of the friction between the roller and the material tray, the rotation of the roller meets the resistance. The resistance is greater than the magnetic attraction between magnet and the hoop in the moment transmission device, and hoop, front end housing, rear end housing and initiative bevel gear will stall, and hollow shaft and initiative major axis then can overcome the magnetic attraction and continue to rotate to realize the purpose of restriction moment size.
