Influence of variation of the distance between centers of the sliding speed gear drives: Application to the crowns of sugar cane mills

In gear transmissions there is a great wear, because there is a sliding velocity between tooth. This sliding in spite of be inevitable has great repercussion over Tooth wear. In gears of sugar mill rollers distance between centers changes during operation and wear is bigger. For this purpose full involute gears are used and sliding increases. Expressions for calculating sliding velocities in such gears are shown in this article.
