Endless power transmission belt having a toothed compression section and method of making the same

摘要: An endless power transmission belt having a toothed compression section and method of making the same are provided, being formed substantially polymeric materials comprising tension section, load-carrying disposed between transverse centerline, an outer layer inner joined to defining interface therewith that is uniformly spaced from by throughout entire width length belt. The has surface in form alternating teeth grooves with respectively roots teeth. thickness tips thereof approximately as layer. softer than inwardly layers so root each tooth distance 25% centerline whereby tends prevent cracking area thereof.
