Abstract
Low noise timing belts for use in belt drive systems include either perforations cut into their thin segments or spiral grooves cut into their thick segments in order to allow air pockets to escape in all directions during teeth engagement of belts and pulleys, thereby reducing the noise generated in the process.
Claims7
In a positive, non-frictional belt drive system that includes a timing belt entrained around spaced apart drive and driven members having teeth thereon, the improvement for reducing the noise level of the timing belt, characterized by:
- alternating teeth and lands on one surface of said timing belt, and wherein said teeth include randomly spaced, non-parallel, transverse and non-orthogonal grooves cut across said teeth that allow air pockets to escape in all directions when said teeth mate with teeth of the drive and driven members during operation of the system.
