What is a belt tensioning system?

Tensioning systems are used to generate and maintain the belt tension and thus ensure reliable power transmission! The belt tension can be maintained during operation, for example, by means of tensioner pulleys. Tensioning pulleys also serve to cushion heavy load changes. In addition, the wrap angle can be increased by tensioner pulleys.

How do you tighten a belt tensioner?

Adjust the tension wheel with a pry rod or adjusting bolt until the tensometer indicates the appropriate belt tensioning. 3. Tighten the locking nut or bolt and the lock washer to 455ft-lb (61bm) of torque so that the tensioner or bracket is fastened.

How to maintain belt tension?

The belt tension can be maintained during operation, for example, by means of tensioner pulleys. Tensioning pulleys also serve to cushion heavy load changes. In addition, the wrap angle can be increased by tensioner pulleys. Tensioner pulleys are also often used for long belt lengths to prevent excessive belt vibration.

How do you tighten a fan belt?

Tighten the locking nut or bolt and the lock washer to 455ft-lb (61bm) of torque so that the tensioner or bracket is fastened. 1. Loosen the large locking nut on the fan hub or fasten the fan hub to the bolt on the mounting bracket. After this work is done, the fan hub will deviate. 2. Turn the adjusting bolt to increase the tension of the belt. 3.

How does a belt tensioner work?

Another way of tensioning a belt is by means of a lever arm to one end of which the tensioner pulley is attached and held in place by a spring. However, if frequent load changes occur during operation, this tensioning system can be excited to strong vibrations.

What is a belt tensioner inclination?

At an inclination of about 15° to 20°, the motor base with its weight ensures a permanent and almost constant belt tension. Various belt tensioner systems are used to maintain the tension in the belt. The most important ones are described in more detail below.
