Abstract

DC60 This invention relates to an expanding and contracting winding shaft (1) specifically for winding metal strips, which has a winding shaft mounted in a rotating manner (2), with at least one notched surface (3) on its outer circumference, with a number of co-working joints (4) with winding surfaces (5) on its outer circumference specifically for winding metal strips, and at least one matching notched surface (7) co-working with the notched surface (3) of the winding shaft (2) in the area at its end (6) away from the winding surface (5). There is also a pathway (8) for moving the joints (4) in the axial direction (A), as well as a system of pipes (9) that deliver lubricant, specifically lubricating grease, to various locations (10) in the winding shaft (1) where lubrication is required. To improve the lubrication of the winding shaft, this invention is provided in The manner in which the pipe system (9) is connected to the lubricant pump (11) is such that the lubricant pump (11) has a control element (12) for pumping, in which the lubricant pump (11) is connected to the path (8) for moving the joint (4) or connected to the shaft of the winding machine (2), and the control element (12) is such that it is connected to Two other elements (2, 8) in a manner in which the pumping process is carried out by the forced action of the path (8) to move the position of the aforementioned joint (4). This invention relates to the type shaft of a winding machine (1) which expands and contracts, specifically for winding a strip of metal, which has a type shaft of the winding machine mounted in a rotating manner (2), with at least one notched surface (3) on its outer circumference, with a number of co-operating joints (4) which have a winding surface (5) on its outer circumference, specifically for the strip of metal, and at least one matching notched surface (7) that co-operates with the notched surface (3) of the type shaft of the winding machine (2) in the area at its end (6) away from the winding surface (5). There is also a path (8) for moving the position of the joint (4) in the axial direction (A), as well as a system of pipes (9) that convey lubricant, specifically. Lubricating grease is passed to various positions (10) in the winding machine's spindle (1) where lubrication is required. To improve the lubrication of the winding machine's spindle, this invention is provided in such a manner that such a piping system (9) is connected to a lubricant pump (11), in which such lubricant pump (11) has an actuating element (12) for pumping, in which such lubricant pump (11) is connected to a channel (8) for moving the segment (4) or connected to the winding machine's spindle (2), and such actuating element (12) is connected to two other elements (2, 8) in such a manner that the pumping process is carried out by the actuating of the channel (8) for moving the segment (4).
