Endless belt for power transmitting according to the present invention is a tension-type belt by link chains, and has high power transmitting efficiency although it can be produced with relatively low cost. With this endless belt, the respective blocks and pins start to contact with sheave side in order near pitch line and the biting pitch into the sheave is made smaller so as to improve silence. Even if the respective blocks 22, 23 are inclined at the time of biting of the endless belt into pulley, each block is contacted with the sheave side at only the projecting outer side face 45 formed in a predetermined bounds, corresponding to the divided pin near the pitch line (P-P). Therefore, total four parts, the projecting outer side faces 45, 45 of the first and second blocks, and a pair of the divided pins are abutted on the sheave side in order in one pitch of the link chain so as to make the biting pitch smaller and decrease polygon effects.
Endless belt for power transmitting having many pins comprising a pair of divided pins having rolling surfaces capable of abutting on each other, many link plates comprising link chains alternately connected by said pins, and first and second blocks having projection portions capable of contacting with each other in front and rear direction, a concave slot provided on the opposite side for receiving said divided pin, and an open hole penetrating said link chain in said front and rear direction, comprising:
Endless belt for power transmitting having many pins each having a rolling surface and many link plates alternately connected by said pins so as to comprise a link chain, comprising:
