I agree Tony , and changing the top pulley to a "flat" type it would then need some kind of tensioner ,which will turn it into a serpentine kit not ?
Many thanks for your comments.
For understanding the system you have to deal with the physical law of the belt friction: with similar friction coefficients at both pulleys the greater pulley will see no sliding. Therefore you actually do not need a groove at the greater pulley. When producing v-belt pulley systems until now it was normal to take grooved pulleys.
You need a certain energy for bringing the belt out of the groove. This means a belt running on an ungrooved pulley is consuming less energy than a belt running on a grooved pulley.
Overall the system needs less energy, is easier to produce and enables a fast belt change without any tool.
