The existing connection method is to directly stick the belt on the surface of the drum and then wind it, or use a pressure plate to press the belt on the surface of the drum through bolts and then wind it. The disadvantage of this connection method is that the joint between the belt and the drum cannot be smoothly transitioned during winding. The life of the belt and the driving torque of the pulley are adversely affected. In addition, several turns of the belt need to be pre-wound to ensure that the belt is reliably connected to the pulley without falling off, resulting in a waste of belt and energy

Embodiment approach
[0010] Open a rectangular slot in the middle of the drum (1), and weld the baffle A (2) and the baffle B (7) on both sides of the inner wall of the drum (1); the end of the belt (6) is located on the lower plate (3) ) and the upper platen (4), the three are connected by five rows of rivets (5). The width between (2) and baffle B (7) is equal.
[0011] During installation, the belt head structure composed of the end of the belt (6), the lower pressure plate (3) and the upper pressure plate (4) is connected by rivets (5) into the rectangular through groove of the drum (1) at a certain angle, and then rotated to Completing the fit: Make the upper curved surface of the lower pressing plate (3) match the inner wall surface of the drum (1), and the upper curved surface of the upper pressing plate (4) cooperate with the outer circle of the drum (1). At this time, the belt (6) is tightened, and the joint Belt (6) just can smooth transition continuous winding.

The invention relates to a belt and roller connecting structure which is formed by a roller, a baffle A, a lower pressure plate, an upper pressure plate, rivets, a belt and a baffle B. The belt and roller connecting structure is mainly characterized in that a rectangular through groove is formed at the middle position of the roller; the baffle A and the baffle B are welded at both sides of the through groove on the inner wall of the roller; a belt fastener structure formed by connecting the end part of the belt, the lower pressure plate and the upper pressure plate by five rows of rivets is totally matched with the rectangular through groove of the roller; both the lower pressure plate and the upper pressure plate are of a variable thickness structure; and the width of the lower pressure plate is equal to that of a part between the baffle A and the baffle B. The belt and roller connecting structure has the beneficial effects that the matching mode is an inserted matching mode, so that the belt and roller connecting structure is convenient to assemble and disassemble; the excircle of the roller is in smooth transition with the top camber of the upper pressure plate and the upper pressure plate is in smooth transition with the belt, so that the service life of the belt is prolonged; and the matching of the lower pressure plate and the inner wall of the roller, the baffle A and the baffle B ensures the connection reliability and the strength of the roller.
Description
technical field [0001] The invention relates to a connection structure of a belt and a drum, which belongs to the field of mechanical technology research. Background technique [0002] When the belt and the pulley are used together, usually the belt is wrapped around the pulley to form a certain wrap angle with the pulley, and the transmission operation is carried out by the friction between the belt and the pulley. But in some occasions, it is necessary to connect one end of the belt to a rigid structure, such as a belt-wound pumping unit, which needs to connect one end of the belt to the drum, and then wind the belt when the drum rotates to achieve the purpose of lifting the suspension. The existing connection method is to directly stick the belt on the surface of the drum and then wind it, or use a pressure plate to press the belt on the surface of the drum through bolts and then wind it. The disadvantage of this connection method is that the belt and the drum joint canno...
