Tool for installing oil seal of drum wheel

The invention discloses a tool for installing an oil seal for a drum wheel. The tool comprises a main tool, a concentric ring and a positioning piece; and the main tool comprises a lower-layer large cylinder and an upper-layer small cylinder, the inner diameter of the concentric ring is matched with the diameter of the lower-layer large cylinder, and the positioning piece is used for clamping themain tool. The tool is suitable for installation of the oil seal of a M8 drum wheel, the concentric ring ensures that the oil seal is coaxial with the inner diameter hole of the oil seal of the drum wheel, the positioning piece can apply pressure uniformly on the surface of the main tool, so that the oil seal is uniformly pressed into the inner diameter hole of the oil seal of the drum wheel, thedamage degree on the surface of the oil seal in the installation process can be effectively reduced, the operation is simple and convenient, and the safety is realized. 本发明公开了一种安装鼓轮油封的工装，包括主工装、同心环和定位件，所述的主工装包括下层大圆柱和上层小圆柱，所述同心环
