CA 2408955

A shaft mounted drive component, such as a cluster roller assembly (30), includes a body member having first and second half members (34, 36) and an opening (40) defining a central axis through which a shaft (72) is received for mounting the body member on a shaft (72). The first and second half members (34, 36) are divided by a cut (38) forming a gap along the central axis. Alignment holes (56) are split by the cut (38). A spacer pin (62) is received within each alignment hole (56) and is substantially the same diameter and has a diameter larger than the gap to maintain alignment and positioning of the half members (34, 36) and rollers (48) as before splitting into respective first and second half members (34, 36) and facilitating replacement of first and second half members (34, 36) on a shaft (72), thus eliminating the need for shaft removal.

L'invention concerne un élément d'entraînement monté sur arbre tel qu'un ensemble (30) groupe de cylindres, qui comprend un élément de corps comportant un premier et un deuxième demi-éléments (34, 36), ainsi qu'une ouverture (40) définissant un axe central destiné à recevoir un arbre (72) pour le montage de l'élément de corps sur l'arbre (72). Le premier et le deuxième demi-éléments (34, 36) sont divisés par une fente (38) formant un écartement le long de l'axe central. Des orifices (56) d'alignement sont divisés par la fente (38). Une tige (62) d'écartement reçue dans chaque orifice (56) d'alignement présente sensiblement le même diamètre que chacun de ceux-ci ; ce diamètre est supérieur à l'écartement de manière à maintenir l'alignement et le positionnement des demi-éléments (34, 36) et des cylindres (48) tel qu'il était avant division en un premier et un deuxième demi-éléments (34, 36) respectifs, et facilite le remplacement des demi-éléments (34, 35) sur l'arbre (72), ce qui permet d'éviter un démontage de l'arbre.
