Effects of too much tension:
1. It will increase the load on the bearings, causing premature wear of the synchronous belt and pulleys.
2. It will reduce the life of the synchronous belt, increase the transmission noise, increase the load on the shaft and bearings, aggravate the heating of the bearings and reduce the life of the bearings.
3. The belt will bend into a polygon with the top of the pulley teeth as the vertex, which is easy to cause the core wire to bend fatigue, and the pressure of the top of the pulley teeth on the bottom of the belt teeth will also increase, which further shortens the life of the belt.
4. It will increase the transmission noise, deteriorate the system transmission precision, increase the pressure on the shaft, and easily damage the bearings.
Effects of too little tension:
1. The synchronous belt will jump teeth due to poor tooth engagement during operation. At the moment of jumping teeth, the belt may break or the belt teeth may break due to excessive tension.
2. It will reduce the accuracy of the synchronous belt transmission movement and increase the vibration noise of the belt.
3. It will cause the belt to jump teeth easily during operation. At the moment of tooth jumping, the belt may break prematurely due to excessive tension.
4 The pitch of the synchronous belt becomes smaller accordingly. When the number of pulley teeth is large, meshing and interference will occur, resulting in premature wear of the teeth.
