Document Type and Number:
WIPO Patent Application WO/2021/093241
Kind Code:
A1
Abstract:
A shock-absorbing spring belt pulley having a unidirectional roller coupling configuration. The belt pulley comprises a belt pulley hub (11) and a unidirectional coupling structure disposed inside the belt pulley hub. The unidirectional coupling structure comprises a threaded core shaft (1) and a connection sleeve (2) sleeved on the threaded core shaft. Multiple roller buffer assemblies are disposed between the threaded core shaft and the connection sleeve, and are distributed in a circumferential direction of the threaded core shaft. The threaded core shaft and the connection sleeve rotatably engage with each other. A shock-absorbing spring (12) is sleeved on the connection sleeve, and two ends of the shock-absorbing spring are respectively connected to the belt pulley hub and the connection sleeve. The belt pulley has good shock absorption and an improved service life, and can be easily installed.
