Claims

[Scope of Claim for Utility Model Registration] 1. Connecting multiple rows of links with pins that are adjacent to each other and staggered from each other to form an endless shape, with link-shaped friction materials arranged and fixed on both ends of the pins, and provided on the drive shaft and driven shaft. Chain type V that is used by wrapping between V pulleys.
In the belt, a stepped narrow diameter portion is provided at both ends of the pin, an axial hollow portion is provided in the stepped narrow diameter portion, and a pin insertion hole and a stepped narrow diameter portion protruding outward are provided in the friction material. and forming the outer end surface of the stepped narrow diameter portion into an inclined surface that matches the slope angle of the V pulley, and communicating the stepped narrow diameter portion with the pin insertion hole;
A notch hole with a slightly larger diameter than the insertion hole is bored, a link constituting the belt is connected to the large diameter part at the center of the pin to form an endless shape, and the link shape is formed in the stepped narrow diameter part at both ends of the pin. Insert the friction material with its stepped narrow diameter part facing outward, and make the tip of the pin protrude from the pin insertion hole into the cut hole of the stepped narrow diameter part by the amount of rivet caulking, and rivet both end surfaces of the pin. A chain-type V-belt characterized by being formed into a V-belt. 2. The chain-type V-belt according to claim 1 of the utility model registration claim, in which a washer is interposed between the stepped portion of the pin and the link-like friction material and is riveted. 3. The chain type V-belt according to claim 1 or 2, wherein the link-like friction material is made of a material selected from metal, FRP, FRM, and sintered body. 4. Utility model registration claims 1 or 2, in which the friction material is metal, and its side surfaces are coated with a wear-resistant layer by hardening, ceramic dispersion plating, hard chrome plating, ceramic spraying, etc. Chain type V belt.
