Bench tests of friction drive of vertical spindle made of poly-V belts

The article reports that to improve the functional characteristics of friction drive vertical spindles, it was proposed replace its conventional V-belts with poly-V-belts. Therefore, rollers changed parameters are installed on spindles while maintaining magnitude rolling radius serial rollers. To determine functionality new drive, a stand single spindle drum created, which allows you all performance indicators polyline drive. main research task this possibility creating traction (friction) force always exceeds resistance cotton bush clamped in narrow working slot harvesting apparatus. assess version comparison technique used when, beginning, (thrust) roller V-belt measured, and then, stand-pull poly-V-belt. A special device made measure pulling belts.
