Abstract: A system and method for increasing a tooth shear strength without also increasing a torsional rigidity of a flexible spline disposed between two hubs of a flexible coupling for transmitting mechanical motion between two shafts includes attaching a stiffening cap to an end of a flexible spline, between the flexible spline and the hubs and inserting a plurality of dowels into the teeth of the flexible spline to reinforce the flexible spline.

Abstract: A bearing cover assembly can be assembled to a bearing housing in which a rolling element bearing is accommodated. The bearing housing assembly includes an annular adapter and an end cap that can be mated together. The annular adapter can have a tapered inner annular surface and can be inserted into the housing bore of the bearing housing. The end cap can have a corresponding outer tapered surface. When the end cap is inserted into the adapter hole defined by the annular adapter, the sliding contact between the tapered inner annular surface and the outer surface radially expands the annular adapter inside the housing bore creating a positive engagement retaining the bearing cover assembly to the bearing housing.

Abstract: A modular pulley assembly for a continuous belt conveyor can be assembly from a plurality of modular pulley disks that can be axially aligned and abut against each other to provide pulleys of differing lengths per demand. The modular pulley disks can be made from a non-metallic material such as a polymer and can manufactured by a suitable molding process. Making the modular pulley disks from non-metallic materials enables the disks to be formed with structural geometries such that the assembled pulley is structurally more rigid and can better distribute torsional loads and momentum from the belt to the support shaft.
