Title:
BELT POWER TRANSMITTING DEVICE AND POWER TRANSMITTING BELT USED FOR SAME
Document Type and Number:
WIPO Patent Application WO/2010/023893
Kind Code:
A1
Abstract:
A belt power transmitting device (A), wherein a drive pulley (1) and at least one driven pulley (2-4) are flat pulleys and power transmission between the flat pulleys is performed by a substantially flat power transmitting surface (b1) of a power transmitting belt (B).  The construction significantly reduces cost of the device and allows the power transmitting belt to achieve power transmission efficiency and durability equivalent to those of a flat belt.  Ridges (82a) extending in the longitudinal direction of the power transmitting belt are formed on the outer surface side thereof.  The ridges (82a) are engaged with peripheral grooves (5a) in restriction pulleys (5, 6) to restrict movement of the power transmitting belt in the width direction thereof.  This causes the power transmitting belt to be resistant to the adhesion of rainwater to the belt and to stably maintain a running condition of the belt.
