CLOSED SIDE-MOUNTED MACHINE WALKING WHEEL
Document Type and Number:
WIPO Patent Application WO/2021/196320
Kind Code:
A1
Abstract:
Disclosed is a closed side-mounted machine walking wheel. The closed side-mounted machine walking wheel comprises a roller body (1). The roller body (1) is internally provided with a roller inner hole (4), the roller inner hole (4) is internally provided with a closed bearing seat (10), one end of the closed bearing seat (10) extends to the exterior of the roller inner hole (4) and is rotationally clamped to the outer side wall of the roller body (1), the outer surface of the other end of the closed bearing seat (10) is rotationally connected to a bearing (7), and the outer surface of the bearing (7) is fixedly connected to the inner side wall of the roller body (1). By using the bearing seat structure and making the bearing seat closed, dust and granular scattered materials are prevented from entering a roller, a bearing inner hole is in interference fit with the outer diameter of the bearing seat, the outer diameter of the bearing is in interference fit with the roller inner hole, and the bearing seat and a shaft are kept static, thereby eliminating a radial gap caused by a traditional mounting manner, and thus making the transmission of the roller more stable.
