What Is a Tensioner Pulley?

The tension wheel is a follower wheel pressed on the belt in order to change the angle of the belt pulley or control the tension of the belt. It is a belt-driven tensioning device. When the center distance of the belt cannot be adjusted, a tensioning wheel can be used to tension the belt.

The tensioner is a tensioning device driven by a belt. When the center distance of the belt cannot be adjusted, the tensioner can be used to tension the belt. Tensioner is for change

The tensioning wheel is composed of a friction unit, a torsion spring, a bearing, a pulley and some components. The picture shows the synchronous toothed belt tensioning mechanism

Usually the tensioning wheel is placed on the loose edge of the belt, because the tensioning force required to place the tensioning edge is large, and the tensioning wheel is also

The tensioner is a tensioner that adjusts the transmission of the pulley, so it is generally used in electric motors.

Tensioner and tensioner

1. The tensioning force of the tensioning wheel must not be too small. If it is too small, the friction between the belt and the working wheel will be small, and eventually the belt will slip. Similarly, the tensioning force of the tensioning wheel must not be too large. Excessive tensioning force will increase the belt load, cause damage to the belt, and cause damage to the bearing of the work wheel.

2. The tensioning wheel should generally be placed on the inner side of the loose edge, so that the belt is only bent in one direction. At the same time, it should be as close to the large wheel as possible to avoid unduly affecting the wrap angle of the small wheel. If the tensioner is placed outside the loose edge, it should be as close as possible to the small pulley. The groove dimensions of the tensioning pulley are the same as those of the pulley, and the diameter is smaller than that of the small pulley.
