Claims

[Claims for Utility Model Registration] (1) Four pins are attached to one pitch to connect each link, and two of the pins are used as pivot pins parallel to the pitch line so that they can make frictional contact with the V-shaped pulley. For smoothing, both end surfaces are sloped surfaces or surfaces capable of frictional contact, and two of the pins are used as stopper pins, parallel to the pitch line and at a certain distance from the pivot pin, and each link is bent around the pivot pin. In case, V
A chain characterized in that one of the pin holes of the inner and outer links is an arc-shaped long hole centered on the pivot pin so that the bending is allowed only in the inward direction when wrapping around the mold pulley. belt. (2) The chain belt according to claim 1, which is a registered utility model, in which all four pivot pins and four stopper pins are able to come into frictional contact with a V-shaped pulley. (3) Claim No. 1 for utility model registration in which only the stopper pin mentioned above can be brought into frictional contact with the V-shaped pulley.
Chain belt as described in section. (4) Among the four pins mentioned above, the pivot pin is arranged on the outer periphery of the pitch line, while the stopper pin is arranged on the inner periphery of the pitch line.
Chain belt according to item 2 or 3. (5) A pair of gourd-shaped block pins and kicker pins are inserted into pin holes as bending shafts between chain links to connect the links, and only the block pins protrude from the outer links to both sides, allowing frictional contact with the V-shaped pulley. The end face is made an inclined surface or a surface capable of frictional contact for smoothing, while the inner periphery of the pin hole of the inner link has a relief part and a gourd so that bending of the link only in the inward direction when wrapped around the V-shaped pulley is allowed. A chain belt characterized by forming a convex surface to match the side surface of a shaped pin. (6) The chain according to claim 5 of the utility model registration, in which a protrusion is formed on the link without protruding the block pin, and a block as a separate member that makes frictional contact with the V-shaped pulley is fixed to the protrusion. belt. (7) In a chain belt that is wrapped around a V-shaped pulley and equipped with a block pin for frictional contact with the V-shaped pulley, an endless elastic band made of a highly elastic material such as rubber or urethane is chained. A chain belt characterized by incorporating. (8) The chain belt according to claim 7, wherein the links constituting the chain are approximately triangular in shape and have a protrusion, and a block pin is attached to the protrusion. (9) Utility model registration claim 7, in which insertion holes are formed in the elastic band at a constant pitch, and the block pins are inserted into the insertion holes and incorporated into the chain.
Chain belt according to item 8 or item 8. (10) In a chain belt that is wrapped around a V-shaped pulley and equipped with a block pin for frictional contact with the V-shaped pulley, an elastic block made of a highly elastic material such as rubber or urethane is used.
A chain characterized in that the elastic blocks are attached to every other block pin, and the end surfaces of the elastic blocks are in contact with or close to the side surfaces of other adjacent block pins, while the side surfaces of the elastic blocks are substantially flush with the end surfaces of the block pins. belt. 〓(11)１１〓 A request for registration of a utility model in which the above-mentioned elastic block is formed from a link part and a block part, a block hole is bored in the center of the block part for inserting a block pin, and the link part is incorporated into a chain link. Chain belt according to item 10.
