AI Technical Summary
Traditional roller can ear fixing methods are prone to loosening, difficult to maintain, and result in uneven stress, affecting the safety and service life of the equipment.
The positioning and connection mechanism is adopted to achieve rapid and accurate positioning of the roller assembly and the swing frame through insertion-rotation-clamping. Combined with the self-locking property of the trapezoidal bolts, it avoids loosening of the connection, and the through-hole fixing of the plug sleeve achieves force distribution and convenient maintenance.
It improves the stability of the roller can ear, avoids the loosening problem in traditional connection methods, reduces maintenance difficulty, achieves force distribution effect, and improves the operational safety and service life of the equipment.

A strong stability roller cage lug, comprising a support (1), characterized in that: The upper surface of the support (1) is rotatably connected to a swing frame (3), and a positioning connection mechanism (5) is provided on the outside of the swing frame (3), and a fixing mechanism (4) is provided inside the positioning connection mechanism (5). The positioning connection mechanism (5) includes a circular positioning recess (52), which is fixedly connected to the outside of the swing frame (3). A circular positioning boss (51) is inserted into the inner wall of the circular positioning recess (52). A positioning plate (53) is fixedly connected to the inner wall of the circular positioning boss (51). There are two positioning plates (53). The positioning plates (53) are distributed around the axis of the circular positioning boss (51). A positioning L plate (54) is fixedly connected to the side of the circular positioning recess (52) near the circular positioning boss (51). The side of the positioning L plate (54) near the circular positioning recess (52) is in close contact with the side of the positioning plate (53) near the circular positioning boss (51). A positioning groove (55) is opened on the outer surface of the circular positioning recess (52). A connecting hole (56) is opened at the axis of the circular positioning recess (52).
2. The strong stability roller cage according to claim 1, wherein: The fixing mechanism (4) includes a sleeve (42), which is slidably connected inside the positioning groove (55) and inside the swing frame (3).
