Bearings for rollers for guiding the belt of a conveyor line

摘要

The side walls (1a) bear rollers (3) which are supported in bearings (5) on the side walls (1a) for guidance of drive belts. The bearings (5) are displaceably mounted on the side walls (1a) for alignment of the path of the belt and have elongated holes (6a) for screws (7). The bearing (5) is formed from a flat bar and has inclined pushback surfaces (5a) as a working surface for an adjustment tool (9), the simple mode of operation of which is easily recognised. When the nuts (8) have been loosened, the screwdriver being used as an adjustment tool (9) is guided through an admission hole (6b) in the side wall (1a) and the bearing (5) is displaced into the desired position, it being guided by the elongate holes (6a) on the square projections (7a) of the screws (7). The holes (6 and 6b) of the side wall (1a) form a row of holes used to position the bearings at the desired distances and serve simultaneously for admission of the screwdriver. <IMAGE>
