Description

Technical Field

[0001] The invention relates to the technical field of bearing puller support structures, and in particular to a novel bearing puller support structure. Background Art

[0002] The bearing puller support structure refers to the part of the bearing puller used to support and fix the puller body and transmit the pulling force. This structure is usually composed of a series of solid components that work together to ensure that the bearing can be safely and effectively pulled out from the bearing seat or other installation position.

[0003] When the bearing is disassembled using the bearing puller support structure, the screw hole block can be held to spirally move the first threaded rod in the inner wall of the screw hole block to one end to a certain position, and then several elastic limit blocks on the first threaded rod are inserted into the inner ring of the bearing to fix it. At this time, the first threaded rod is held, and the screw hole block is spirally moved to one end on the first threaded rod, and the pressing sleeve is pushed to move to one end so that one side thereof abuts against the side of the object on which the bearing is installed so that the elastic limit block and the pressing sleeve limit and clamp the bearing. At this time, the pressing sleeve and the first threaded rod are in a stationary state. Only the screw hole block needs to be continuously twisted to drive the first threaded rod, several elastic limit blocks and the bearing to move in a certain direction, and the bearing is pulled out and disassembled from the object. Since the sizes of the bearings to be disassembled are different, and the distances between several elastic limit blocks are fixed, when disassembling the bearings with larger inner ring inner wall sizes, the situation of being unable to limit may occur, which reduces the adaptability of use. At the same time, the elastic force of the elastic limit block is limited, and it is easy to be damaged after long-term use, thereby reducing the service life of the bearing puller.

[0016] The effect achieved by the above components is as follows: by setting an auxiliary device, when using the bearing puller support structure to disassemble the bearing with the inner ring fixed to the object and the outer ring exposed to the outside, the two clamping blocks can be manually pressed inward to a certain position in the inner wall of the slide groove according to the height of the bearing, so that one end of the clamping block is completely received in the inner wall of the slide groove, driving the spring to be compressed. At this time, the second limit block can be pulled outward to a certain position in the inner wall of the first limit block, so that when the distance between one end of the second limit block and one side of the first limit block is greater than the height of the bearing to be disassembled, the clamping block is released, and under the resetting action of the spring and the telescopic rod, one end of the clamping block can be inserted into the corresponding clamping hole to fix the adjusted second limit block on one side of the first limit block. When disassembling, First, push the first limit block and the second limit block outward to a certain position through the screw hole abutment block, then set the second limit block and the first limit block on the outer ring of the bearing, and at the same time, abut one side of the pressing sleeve against the side of the object on which the bearing is installed so that the second limit block and the pressing sleeve clamp the bearing in a limited position, finally, rotate the second threaded rod to drive the screw hole abutment block to move upward, and at the same time drive the pull rope to reel in, move the first limit block and the second limit block toward the center position of the first threaded rod, clamp and fix the bearing from the outer ring, and then you only need to continue to twist the screw hole block to drive the first threaded rod, several first limit blocks and second limit blocks and the bearing to move in a certain direction, pull them out and remove them from the object, thereby improving the adaptability of the bearing puller support structure.
