The invention relates to a belt pulley transmission mechanism. The belt pulley transmission mechanism comprises a belt pulley, a transmission shaft in transmission fit with the belt pulley and a transmission belt arranged on the surface of the belt pulley in a sleeving mode, the belt pulley and the transmission shaft are connected through a taper sleeve, an elastic notch is formed in the inner wall of the taper sleeve and formed in an inner taper hole of the belt pulley, the transmission shaft is arranged in an inner hole of the taper sleeve, a pre-tightening screw and a loosening screw are arranged between the taper sleeve and the transmission shaft, so that a pre-tightening state and a loosening state exist between the taper sleeve and the transmission shaft, and in the pre-tightening state, the taper sleeve and the belt pulley are in expansion interference fit and are in transition fit or interference fit with the transmission shaft at the same time; and in the loosening state, thebelt pulley is disengaged from the taper sleeve, the taper sleeve and the transmission shaft are in clearance fit, so that the belt pulley and the taper sleeve can move in the axial direction of the transmission shaft, the transmission shaft comprises a connecting shaft section matched with the belt pulley, the two sides of the connecting shaft section protrude out of the belt pulley to form a space enabling the belt pulley to move in the axial direction to adjust the installation position, thus, the problem that the preassembled belt is not aligned is solved.
Description
technical field [0001] The present disclosure relates to the field of pulleys, and in particular, to a pulley transmission mechanism. Background technique [0002] In the process of belt drive assembly, often after the belt is pre-assembled, the misalignment (the coplanar deviation of the pulleys is too large, exceeding the allowable value of the national standard) often occurs. Generally, it can only be reworked, re-installed fasteners, and re-calibrated. The repeated workload is heavy, and due to the moving of the installation position, other installation interfaces of the parts are misaligned; or even in order to ensure the accuracy of other installation interfaces, they will give in to accept the misalignment, which will directly lead to the reduction of transmission efficiency and will greatly shorten the belt and transmission. The service life of the housing bearings. Contents of the invention [0003] An object of the present disclosure is to provide a belt drive m...
