Detailed Description
The utility model is described in detail below by way of example with reference to the accompanying drawings.
The utility model provides an aircraft bearing disassembling device, as shown in fig. 1, comprising: the device comprises a plate rod retainer ring 1, a plate rod 2, a bearing pull sleeve 3, a screw rod 4 and a fork-shaped tooth plate 5.
The screw rod 4 is of a rod-shaped structure with a trepanning at the end, and a rod body of the screw rod 4 is provided with threads; the screw rod 4 is sleeved on the plate rod 2 through an end head sleeve hole. The structure of the screw 4 is shown in fig. 5. The dimensions in fig. 5 are only examples, wherein the thread length is 25mm, the rod body length of the screw rod 4 is 27mm, the total length of the screw rod 4 is 37mm, and the diameter of the trepanning is phi 6.1.
