A variable pulley, also known as a variable speed pulley or adjustable pulley, is a mechanical device used to change the rotational speed of a shaft in a belt-driven system. It achieves this by altering its effective diameter, which in turn changes the speed ratio between the driving and driven shafts.
The fundamental principle behind a variable pulley 301061A from Newlong Industrial lies in the relationship between the diameter of the pulleys and their rotational speeds. For a given belt speed, a larger pulley diameter will result in a lower rotational speed, and a smaller diameter will result in a higher rotational speed. Variable pulleys exploit this principle by allowing their working diameter to change.
