    • An improved chain drive sprocket or the like in the form of a sprocket member. The composite sprocket member includes a metallic hub portion having T-shaped lands and T-shaped grooves formed on the outer periphery thereof coaxial with the axis of rotation of the hub portion, and a toothed ring formed of synthetic resin material having an aperture formed therein with T-shaped lands and T-shaped grooves formed on the inner periphery thereof sized and shaped for close sliding coaxial engagement with the corresponding lands and grooves of the hub portion. The hub portion is preferably formed of sintered steel powder impregnated with cupreous alloy. The toothed ring portion is preferably formed of nylon. The drive sprocket may be employed in combination with the power output shaft from a motorcycle power transmission. The composite member may be slightly modified to form a composite spur gear or the like.
    • 链轮构件形式的改进的链条传动链轮等。 复合链轮构件包括:金属毂部,其具有与轮毂部的旋转轴线同轴的外周上形成有T形平台的T形槽,以及由合成树脂材料形成的齿形环,所述合成树脂材料具有形成在其中的孔 在其内周上形成有T形焊盘和T形槽,其尺寸和形状用于与轮毂部分的相应焊盘和槽部紧密滑动同轴接合。 毂部优选由浸渍有铜合金的烧结钢粉末形成。 齿形环优选由尼龙形成。 驱动链轮可以与来自摩托车动力传动的动力输出轴组合使用。 可以将复合构件略微修改以形成复合正齿轮等。
