Abstract
Official abstract text for this publication.
The present invention provides a toothed belt transmission that reduces noise and vibration resulting from the engagement between a toothed belt and a toothed pulley, and that improves the durability of the toothed belt. The toothed belt transmission in which a tooth height of a toothed belt and a tooth height of a toothed pulley are set so that when the toothed belt and the toothed pulley start engaging with each other, tooth tip parts of the toothed belt and tooth bottom parts of the toothed pulley contact each other before tooth bottom parts of the toothed belt and tooth tip parts of the toothed pulley contact each other.
First claim
Opening claim text (preview).
What is claimed is: 1. A toothed belt transmission transmitting rotation, comprising: a toothed belt having belt teeth, and a toothed pulley having pulley teeth being engaged with each other, wherein a tooth height of the toothed belt and a tooth height of the toothed pulley being set so that when the toothed belt and the toothed pulley start engaging with each other, tooth tip parts of the toothed belt and tooth bottom parts of the toothed pulley contact each other before tooth bottom parts of the toothed belt and tooth tip parts of the toothed pulley contact each other, wherein tooth surfaces of the belt teeth have tooth root-side concave curved parts continuous with the tooth bottom parts of the toothed belt, respectively, wherein tooth surfaces of the pulley teeth have tooth tip-side convex curved parts continuous with tooth tip parts of the toothed pulley, respectively, and wherein the toothed belt and the toothed pulley are set so that when the toothed belt and the toothed pulley start engaging with each other, the tooth tip parts of the toothed belt and the tooth bottom parts of the toothed pulley contact each other, and then, the tooth root-side concave curved parts of the toothed belt and the tooth tip-side convex curved parts of the toothed pulley contact each other, and further then, the tooth bottom parts of the toothed belt and the tooth tip parts of the toothed pulley contact each other, and lateral parts of the tooth surfaces of the toothed belt and lateral parts of the tooth surfaces of the toothed pulley contact each other, in region between a contact point where the tooth tip parts of the toothed belt and the tooth bottom parts of the toothed pulley contact each other and a contact point where the tooth root-side concave curved parts of the toothed belt and the tooth tip-side convex curved parts of the toothed pulley contact each other. 2. The toothed belt transmission according to claim 1 , wherein the tooth height of the toothed belt is set to be greater than the tooth height of the toothed pulley. 3. The toothed belt transmission according to claim 1 , wherein a curvature radius of the tooth root-side concave curved parts of the belt teeth is set to be greater than or equal to a curvature radius of the tooth tip-side convex curved parts of the pulley teeth. 4. The toothed belt transmission according to claim 1 , wherein a pressure angle of tooth surfaces of the belt teeth is set to be greater than a pressure angle of tooth surfaces of the pulley teeth.
