Abstract
A silent chain that can reduce friction loss during travel of a chain. A silent chain 1 is configured by stacking a large number of link plates 2 comprising a pair of tooth parts 22 and pin holes 21 in the thickness direction and the lengthwise direction, and also arranging guide plates 4 on the outermost side of the link plates 2, and coupling the link plates 2 and the guide plates 4 by means of connecting pins 3. Protruding parts 45 which can come into sliding contact with guide parts 56B of a chain guide 56 and guide parts 57B of a tension arm 57 during travel of the silent chain 1 are provided on an outer side surface 4A of the guide plates 4. The contact between the silent chain 1 and the chain guide 56 and tension arm 57 is made to be point contact, and friction loss during travel of the chain can be reduced.
Claims19
A silent chain comprising a plurality of link plates comprising a pair of tooth parts and pin holes are stacked in the thickness direction and the lengthwise direction and are respectively coupled in a pivotable manner by connecting pins, and also guide plates are arranged on the outermost side,
- said silent chain being characterized in that at least one small protrusion which is configured to come into sliding contact with a guide part of a chain guide or tension arm during travel of said silent chain is provided on the outer side surface of the abovementioned guide plates.
