DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: This example is intended to solve the problem of needing to replace three-jaw pullers of different sizes when disassembling bearings of different sizes. Figures 1-4A motor bearing disassembly device includes a fixing plate 110, a support rod 111 and a screw 112. The screw 112 is threadedly inserted in the fixing plate 110. The support rod 111 is used to fix the outer ring of the bearing. The support rod 111 is movably inserted at the bottom of the fixing plate 110. The support rod 111 is located outside the screw 112. A control cavity 114 is provided in the fixing plate 110. A slide groove 115 corresponding to the support rod 111 is provided at the bottom of the fixing plate 110. The slide groove 115 is connected to the control cavity 114. The top end of the support rod 111 is slidably inserted in the control cavity 114 through the slide groove 115. An adjustment component 120 for adjusting the support rod 111 is provided in the control cavity 114.

[0023] The adjustment assembly 120 includes an adjustment screw 121 arranged in the control cavity 114, and an adjustment ring 122 fixedly installed on the top of the support rod 111. The adjustment ring 122 is movably sleeved on the end of the adjustment screw 121. A control rod 123 is installed on the end of the adjustment screw 121. A control groove 124 corresponding to the control rod 123 is opened on the side of the fixed plate 110. The control groove 124 is connected to the control cavity 114, and the control rod 123 is rotatably inserted in the control groove 124.

[0024] The adjustment assembly 120 and support rod 111 are arranged in three groups, arranged in a triangular array with the screw 112 as the center. An adjustment gear 125 is fixedly mounted on the end of the control rod 123. The fixed plate 110 is fitted with a toothed ring 126 corresponding to the adjustment gear 125, which meshes with the adjustment gear 125. A top plate 132 is mounted on the outer sleeve of the screw 112 to push the inner ring of the bearing. This top plate 132 is located inside the support rod 111 and is fixedly mounted with a limit rod 133. A limit slot 134 corresponding to the limit rod 133 is defined at the bottom of the fixed plate 110, and the limit rod 133 is inserted into the limit slot 134.

[0025] Start by removing the bearing from the motor, then set the bearing sleeve on the outside of the screw 112, and engage the adjusting gear 125 at the end of the control rod 123 by rotating the rotating gear ring 126 to drive the adjusting screw 121 to rotate. As the adjusting screw 121 rotates, the control adjusting ring 122 drives the three support rods 111 to gather from the outside toward the bearing, thereby clamping and fixing the outer ring of the bearing. At this time, rotating the screw 112 drives the top plate 132 to contact the inner ring of the bearing, thereby separating the inner ring of the bearing from the inner ring of the bearing. As the inner ring and outer ring of the bearing are removed, rotating the gear ring 126 in the opposite direction can control the support rods 111 to disperse outward, thereby releasing the bearing. At this time, the outer ring of the bearing can be removed from the screw 112.

[0026] In this embodiment: by adjusting the design of the screw rod 121 and the control rod 123, the operator only needs to simply rotate the gear ring 126 to adjust the position of the support rod 111, thereby clamping and fixing the bearing. The operation is easier and more convenient, and the complexity of manual alignment and adjustment is reduced. Since the support rod 111 can quickly gather and fix the outer ring of the bearing, combined with the design of the top plate 132 directly pushing the inner ring, the disassembly process is more efficient and the disassembly time is reduced. By adjusting the component 120 and its control mechanism, the disassembly device can easily adapt to bearings of different sizes without the need to replace tools of different sizes, thereby improving the flexibility and efficiency of operation.

[0027] Example 2: This example is intended to help solve the problem of shaking or offset that may occur during operation. This example is an improvement made on the basis of Example 1. For details, please refer to Figures 1-4 A stabilizing ring 127 is fixedly mounted within the gear ring 126. A ring groove 128 corresponding to the stabilizing ring 127 is defined on the exterior of the fixing plate 110. The slide groove 115 of the stabilizing ring 127 is inserted into the ring groove 128. A slider 130 is mounted on the adjustment ring 122. A slide groove 131 corresponding to the slide groove 130 is defined within the control chamber 114. The slider 130 is slidably mounted within the slide groove 131.

[0028] A spring 135 is provided in the limiting groove 134. One end of the spring 135 is fixedly connected to the inner wall of the limiting groove 134, and the other end of the spring 135 is fixedly connected to the top of the top plate 132. The rebound effect of the spring 135 helps the top plate 132 to return actively when no pressure is applied.

[0029] In this embodiment: through the fixed installation of the stabilizing ring 127, the stability of the device can be increased, and shaking or deviation during operation can be prevented, thereby ensuring the accuracy and safety of the disassembly process. Through the design of the slider 130, better sliding performance is produced, ensuring that the support rod 111 in the control cavity 114 is adjusted more accurately, and reducing operational errors caused by the unstable position of the slider 130.

[0030] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
