Technical Field
[0001] The utility model relates to the technical field of bearing seat disassembly, in particular to a guide and limiting device for disassembling a bearing seat. Background Art
[0002] The core function of the bearing seat is to fix and support the bearing. It is usually located at both ends of the shaft, and then the bearing seat is fixedly connected to the base through positioning bolts for use, ensuring that a certain positional relationship is maintained between the bearing and the connecting piece. In addition, the bearing seat also plays a balancing role, so that the outer ring of the bearing remains fixed, while the inner ring can rotate freely and keep consistent with the direction of transmission.
[0003] During use, the inner wall of the bearing seat needs to be connected with the outer wall of the rotating shaft by interference fit. During the disassembly of the bearing seat, it is necessary to separate it from the connected rotating shaft, and then remove the positioning bolts connected to the bearing seat. The existing method of separating the two is usually to use a copper hammer to knock, which not only increases the labor of the staff, but also reduces the efficiency of disassembly. Utility Model Content
[0004] The technical problem to be solved by the utility model is that the bearing shaft and the rotating shaft cannot be separated conveniently and quickly, resulting in a reduction in disassembly efficiency.
[0005] In order to solve the above problems, the technical solution of the utility model is: a guiding and limiting device for disassembling a bearing seat, comprising a bearing seat and a rotating shaft connected to the bearing seat, a U-shaped frame matching with it is sleeved on the bearing seat, and abutment seats 1 and 2 that cooperate with each other are fixed on both sides of the inner wall of the U-shaped frame at both ends of the bearing seat, and fastening bolts are threadedly penetrated on the two abutment seats 2, and the inner ends of the fastening bolts abut against the outer wall of the bearing seat, and abutment bolts are also threadedly penetrated on the U-shaped frame corresponding to the end of the rotating shaft, and the axis of the abutment bolt is coaxially arranged with the axis of the rotating shaft.
[0006] Furthermore, grooves are respectively provided on the inner walls of the U-shaped frame corresponding to the two fastening bolts, and through holes are also provided on the grooves at positions corresponding to the heads of the fastening bolts, and the size of the through holes is larger than the size of the heads of the fastening bolts.
[0007] Furthermore, anti-slip pads are respectively provided on the inner walls of the two abutment seats.
[0008] Furthermore, handles are fixedly provided on both sides of the U-shaped frame.
[0009] Furthermore, the outer side corners of the U-shaped frame are respectively provided with rounded corners.
[0010] The advantages of the utility model compared with the existing technology are:
[0011] The U-shaped frame is stably fixed to the bearing seat by the cooperation of the arranged U-shaped frame, the abutment seat 1, the abutment seat 2, the fastening bolts and the abutment bolts, and the abutment seat 1 and the abutment seat 2 can be placed on both sides of the bearing shaft first, and then the fastening bolts are rotated to make their ends tightly abut against the outer wall of the bearing seat under the action of the thread force, so that the U-shaped frame is stably fixed to the bearing seat, and then the positioning bolts of the bearing seat on the other end of the rotating shaft are removed, so that the other end of the rotating shaft is in a movable state, and finally the abutment screw is rotated to make its end move to the left under the action of the thread force to abut against the end of the rotating shaft, and as the abutment screw continues to rotate, the rotating shaft is driven to move to the left, so that the rotating shaft and the bearing seat are conveniently and quickly separated, thereby improving the disassembly efficiency of the device.
