In other words, the belt tensioner drive is located in the B-pillar of the motor vehicle.
A belt tensioner may be equipped with a drive shaft and electric motor. The drive shaft may also contain a worm gear or worm wheel. The drive shaft also has an intermediate gearbox. Once the tensioner is set, it is ready to move to its safe-position position. It is a relatively simple and inexpensive replacement for your belt. When replacing a multi-ribbed belt, be sure to replace the tensioner along with the belt. Gates recommends replacing all wear parts at once.
In the event of a faulty drive belt tensioner, the belt will not stay taut. The pulley can wobble and cause the belt to fray. In addition to this, the bearings can cause a loud squealing noise. In this case, the accessory motors will continue to run, while the belt itself will not. Therefore, replacing the timing belt tensioner is an important part of maintaining the car.
In some systems, the belt tensioner uses a worm gear as the first gear. This results in rolling engagement of the screw’s teeth. This reduces noise and vibrations, while maximizing the efficiency of the belt tensioner drive. Additionally, a worm gear can eliminate the need for additional parts in belt tensioners. While this may not be practical in all instances, it is a good choice for space-constrained environments.
