Abstract: A stator assembly for a progressive cavity pump or a progressive cavity motor includes connectors for connecting functional elements and at least one stator, the stator including an outer pipe as well as a lining subject to wear which is disposed inside the outer pipe, the at least one stator being disposed between the connectors such that a cavity extending across the entire stator assembly for housing a rotor is created. Between at least one of the connectors and at least one stator adjacent thereto and/or between adjacent stators an adhesion region is provided, whereby in the adhesion region an adhesive is disposed in such a way that between the at least one connector and the at least one stator adjacent thereto and/or between said respectively adjacent stators a substance-to-substance connection is created.

Abstract: A drive unit for a grain elevator, in particular for agricultural machines, has a drive wheel operatively connected to a screw conveyor for conveying crop into the grain elevator. The drive wheel is provided with a retainer which may be engaged in a positive locking and/or friction-type connection with a continuous tension device of the grain elevator provided with one or more paddles so as to drive the continuous tension device. Several openings are provided in the drive wheel between the arms holding the retainer in such a way that this allows or facilitates crop conveyed by the screw conveyor into the grain elevator along a direction of conveyance to flow through the drive wheel.

Abstract: The present invention relates to a rod belt for rod belt conveyors of agricultural machines comprising rods (5) arranged transverse to the direction of transport and parallel to each other, the rods (5) comprising flattened and perforated attachment areas (5.1) by means of which they lie in contact with elastic belts (2) of high tensile strength revolving parallel to each other and being connected to the belts (2) via rivets or similar attachment means penetrating the attachment area (5.1) and the belt (2), both ends (9) of which belt constituting a joint (8). It is the object of the invention to provide a rod belt of this type having an endless connection of high stability while, at the same time, being easy to disassemble and mount.
