Belt wheel and running-in device

The utility model provides a belt wheel and a running-in device, the belt wheel is in driving connection with a gear transmission mechanism so as to drive the gear transmission mechanism to rotate, the belt wheel comprises a plurality of wheel bodies, the plurality of wheel bodies are sequentially connected along the circumferential direction so as to form the belt wheel, and two adjacent wheel bodies are detachably connected. The belt wheel solves the problem that in the prior art, when a gear transmission mechanism is in running-in, a belt wheel is inconvenient to disassemble and assemble. 本实用新型提供了一种带轮及磨合装置，该带轮与齿轮传动机构驱动连接，以驱动齿轮传动机构转动，带轮包括：多个轮体，多个轮体沿周向方向依次连接以围成带轮，其中，相邻的两个轮体之间可拆卸地连接。本实用新型的带轮解决了现有技术中的齿轮传动机构磨合时带轮不方便拆装的问题。
