Problems solved by technology

[0004] Existing synchronous belts are usually made of silica gel, but limited by the sticky properties of silica gel itself, its friction performance is poor under complex working conditions, the bonding force between the inner ring and the outer ring is not ideal, and the tensile strength is relatively low. Poor, it is difficult to meet the driving and working requirements of new self-mobile robots

Description

technical field [0001] The present application relates to the technical field of robots, in particular to a self-moving robot, a synchronous belt and a method for preparing the synchronous belt. Background technique [0002] Autonomous Mobile Robots (AMR) is a robot that carries various sensors and is programmed to move autonomously. The current self-mobile robot is usually driven by a synchronous belt. As a key component of the self-mobile robot, the performance of the synchronous belt directly affects the performance of the self-mobile robot. [0003] The synchronous belt includes an inner ring and an outer ring. The inner surface of the inner ring is the driving surface, and the outer surface of the outer ring is the working surface. The driving surface transmits power through the meshing of the belt teeth and the gear. The working surface is in contact with the working medium such as glass to generate driving force. [0004] Existing synchronous belts are usually made ...
