Why must the brake discs be sold in sets?
If we only sell wheels, due to the limited on-site conditions, the fixing bayonet between the traction wheel and the brake disc is inconvenient to assemble. If we leave the hole of the traction wheel larger, it will be easy to assemble on site, but because the bayonet has movement clearance, Then the force will deform, causing the traction wheel to swing out of synchronization with the brake disc. Therefore, it affects not only the life of the wire rope (PS: Many projects are equipped with wheels from outside manufacturers, and the elevator traction wire rope only took half a year to be replaced due to wear and tear), the car will also vibrate, and the comfort will definitely be reduced. !So the factory must directly fix and tighten it on the lathe! Since the two must be synchronized, dynamic balance needs to be done, so as to minimize the error! (PS: This is why dynamic balancing must be done when changing tires on a car. reason).
Choosing the original traction pulley with a pulley is easier to replace, safer and more stable to use, and it also greatly improves the comfort of the wire rope!
