Title:
TENSIONING REGULATOR AND SYNCHRONOUS BELT TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/031610
Kind Code:
A1
Abstract:
A tensioning regulator and a synchronous belt transmission device. The tensioning regulator comprises a mounting regulation assembly, comprising a mounting regulation body; a tensioning regulation assembly, comprising a tensioning connection member (31), a tensioning action member (32) and an elastic member (33), the tensioning connection member (31) being sleeved on the tensioning action member (32), the elastic member (33) being provided in the tensioning connection member (31) and abutting against and acting on the tensioning action member (32), the mounting regulation body being movably connected to the tensioning connection member (31); and an anti-retraction assembly. Since there is a deviation in the mounting position for mounting the tensioning regulator during the production and manufacturing process, by providing the mounting regulation body, the length of the tensioning regulator can be adjusted, so as to adapt to the deviation; by providing the tensioning regulation assembly, the elastic member (33) can automatically extend to provide an elastic force so as to ensure that a tensioning wheel (123) provides a proper tensioning force to a synchronous belt (122); and by providing the anti-retraction assembly, the tensioning regulation assembly is prevented from retracting in a direction away from the anti-retraction assembly, thereby ensuring that a proper tensioning force can be provided.
