A plurality of fastening plates (30) are used to securely connect a plurality of teeth segments (28) to a support member (22) to form a sprocket wheel (34). Each of the fastening plates (30) has a plurality of through holes (42) and a plurality of fasteners (32) engage the holes (42) to secure the teeth segments (28) to the support member (22). Each of the fastening plates (30) also has a flat planar surface (44) which contacts the teeth segments (28) and provides a large area of clamping surface contact. Each fastening plate (30) spans a joint between adjacent teeth segments (28) and contacts a portion of at least two adjacent segments. Because of the large clamping surface area provided by the flat planar surfaces (44) of the fastening plates (30), potential for tangential slippage of the teeth segments (28) under load is greatly reduced.
