TWO PART SPROCKET WHEEL
Two part sprocket wheel (1) adapted to engage modular belt modules in a conveyor belt, where said two part sprocket wheel (1) comprises: - two periphery elements (10,11), each periphery element (10,11) having an outer edge (13) and inner edge (12) and a web body (9) there between, where sprocket teeth (15) are provided on the outer edge (13), and where the inner edge (12) has an engagement surface, and where each periphery element (10,11) has means (16) for being connected and fastened to and adjacent periphery element (10,11), such that the two periphery elements' outer edges (13) form a full circle, said circle being arranged in a common plane, wherein centrally in the sprocket wheel (1) an aperture (20) is provided, said aperture (20) being dimensioned to accommodate a substantially rectangular axle, where the longitudinal axis of the axle is perpendicular to the common plane of the two part sprocket wheel (1), where each part of the sprocket wheel (10,11) has four engagement ridges (21, 22, 23, 24), which engagement ridges (21,22,23,24) when the sprocket wheel is mounted around the axle will engage the axle, where a first pair of ridges (21,22) are arranged orthogonal to each other, and where a bent out section (25), connects the two engagement ridges (21,22), where a second pair of engagement ridges (23,24) is mirrored the first pair (21,22), such that the two engagement ridges (22,23) of different pairs being in the same plane are separated by a cut-out (26), and where parallel to the inner edge, a certain distance away from the aperture (20), assembly flanges (27,28) are provided, where each assembly flange is provided with an aperture (30) on either side of the web (9), where said aperture (30) is surrounded by an upstanding circumferential ridge (31), said ridge on its distal end being provided with centering and engagement means (32), such that as two sprocket wheel parts (10,11) are assembled to a sprocket wheel (1), the centering and engagement means (32) on a first sprocket wheel part (10) engages and centers the corresponding centering and engagement means (32) on the second sprocket wheel part (11), whereby the apertures (30) on the first and second sprocket wheel parts (10,11) overlap, and assembly bolts (33) may be inserted in order to connect and fix the two parts of the sprocket wheel to each other.
