Title:
TOOTHED PULLEY, SYNCHRONIZATION BELT SYSTEM AND ATTACHMENT METHOD OF TOOTHED PULLEY
Document Type and Number:
Japanese Patent JP2022184765
Kind Code:
A
Abstract:
To provide a toothed pulley or the like which can attach a belt between pulleys so as to be capable of setting the attachment tension of the belt to a comparatively-high level even if the belt which is comparatively high in belt elasticity is attached to a pulley layout having no tension impartment mechanism which is in a common use in a prior art (the movement of an inter-axis distance, a tension pulley, a tensioner or the like).SOLUTION: A toothed pulley 1 in which a groove part 14 engaged with a tooth part 21 of a toothed belt 2 is formed at an external periphery comprises: a boss part 111 which can be connected to a rotating shaft; a first split pulley 12 and a second split pulley 13 which are attached to an external peripheral side of the boss part 111, and split into two pieces in a circumferential direction of the boss part 111; and a base member 11 for fixing a positional relationship of the first split pulley 12 and the second split pulley 13 in a rotating shaft direction. The first split pulley 12 is attachable to the external peripheral side of the boss part 111 in a state that the second split pulley 13 is not attached to the external peripheral side of the boss part 111.SELECTED DRAWING: Figure 3
