Title:
BELT PULLEY FOR COMPOSITE TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/032445
Kind Code:
A1
Abstract:
A belt pulley for a composite transmission system. The belt pulley comprises a belt pulley body (1), wherein the belt pulley body (1) is formed by means of connecting several pulley disks, and a belt groove (2) for a belt to be embedded is formed between every two adjacent pulley disks; and opposite end faces of every two adjacent pulley disks form belt groove side faces (3) for friction transmission, each belt groove side face (3) is provided with friction recesses (4), and the friction recesses (4) improve the coefficient of friction between the belt and the belt groove side faces (3). When the belt pulley is under high-power and high-load operation conditions, a belt is stressed to deform, so that side faces of the belt are tightly fitted into the friction recesses (4) in the friction side faces, thereby greatly improving the coefficient of friction between the belt and the belt grooves (2), and reducing or eliminating the phenomenon of slipping of the belt.
