Belt ring expansion sets

Since the late 1950s , drum spokes have adopted variable cross-section structure , between the wheel housing and the shaft has adopted keyless connection , that the ring

expansion sets structure , referred to as gravity conveyor expansion sets makers. Ring expansion sleeve in the structure has been improved continuously , although it is not widely used , but the

development point of view,

It should still be promoted. Belt Ring gravity skatewheel conveyor Expansion sets of Z1-Z5 total of five kinds , with the following characteristics :
1, the transmission torque evenly, so that the shaft reasonable force can be smaller than the bond connecting shaft section .
2 , single-cylinder assembly , axial positioning adjustable , removable and easy maintenance.
3 , the cylinder can be improved manufacturing process , reduce the wheel housing and the shaft machining accuracy.
4 , due to the cancellation of the keyway , the shaft groove sections not weakened, thus reducing stress concentration coefficient.
