The invention discloses a hoisting tool for a gear with annular grooves. The hoisting tool comprises two hoisting plates, two fixing bolt and nut sets and two pipe spacers, the end faces of the hoisting plates are in L shapes, the short edges of the L shapes are oppositely and symmetrically arranged, and the side faces of the two hoisting plates are both in sector shapes. The short edges of the L shapes are arc edges, and the two ends of the two pipe spacers which are arranged in parallel up and down are located between the upper portions of the two hoisting plates respectively. When the gear with the annular grooves is hoisted, the arc-shaped edges at the lower ends of the hoisting plates stretch into the annular grooves in the two sides of the gear correspondingly, one ends of fixing bolts transversely penetrate through the two hoisting plates and the pipe spacers between the two hoisting plates, and the inner side faces of the two hoisting plates clamp the upper rim of the gear through nuts. According to the hoisting tool, the production cost is reduced, and the hoisting efficiency and the gear mounting quality are improved. Gears of multiple sizes can be flexibly hoisted, and the universality of the hoisting tool is improved.

    本发明公开了一种具有环形沟槽的齿轮吊装工具,包括2块吊板、2组固定螺栓螺母组和2根定距管,吊板的端面呈L形,且L形的短边相对地对称设置,2块吊板侧面均呈扇形。L形的短边为弧形边,上下平行设置的2根定距管两端分别位于2块吊板的上部之间。吊运具有环形沟槽的齿轮时,吊板下端的弧形边分别伸进齿轮两侧的环形沟槽中,固定螺栓一端分别横穿过两块吊板和中间的定距管,通过螺母使得两块吊板的内侧面夹紧齿轮上部轮缘。本发明降低了生产成本,提高了吊装效率和齿轮的安装质量。可灵活地吊装多种尺寸的齿轮,提高了本发明的通用性。
