| 07/02/1992 | DE4040847A1 Transferring or delivering roller - comprises shaft, concentrically running tube and 2 disengageable inwardly projecting bearing parts at roller end to allow driven or free rotation AB DE4040844A The end-driven carrying- or delivering roll (10) has a shaft (12), a tube (14) running concentrically to the shaft (12) is new. Two inwardly projecting, oppposed bearing parts are positioned in the space between the shaft (12) and the tube at the ends. The bearing parts are removable from the pipe and are mutually interchangeable. The inner surface (14c) of the tube (14) and the fist bearing part (18) is (in)directly frictionally- or pref. form-connected in the mounting position on the first tube end (14a). The other tube end (14b) is freely rotatable with and/or against the tube. The second bearing part is configured so that it is freely rotatable with the tube in the mounting positions at both tube ends. Tube-shaped bushings (22, 24) at both tube ends, extend into the tube and receive the bearing parts (18, 20). The bushings are fitted to be torsionally resistant against the corresp. inner surface of the tube (14). The corresponding sections of the fist and second bearing part, the tube, bearing parts or the bushings (22, 24) are made of plastic. The roller is pref. made of a polyamide ABS, or metal. USE/ADVANTAGE - The roller is used for transferring or delivering goods when the bearing parts are engaged or disengaged to freely rotate. The conversion from the driven to freely rotating states is simple.
