Description

Technical Field

[0001] The utility model belongs to the technical field related to disassembly of bearing outer rings, and particularly relates to a device for disassembling bearing outer rings. Background Art

[0002] Bearings are critical components in mechanical equipment, widely used in various mechanical transmission and rotation systems. Over extended periods of operation, bearings often experience wear, seizure, or wear due to friction, temperature, and environmental factors, necessitating regular maintenance and replacement. This is particularly true when disassembling bearings. Because the outer ring fits tightly into the shaft hole, traditional disassembly methods typically rely on specialized disassembly tools or require the use of heating, tapping, and other methods. However, traditional bearing outer ring disassembly tools typically require the selection of appropriate tool types based on the bearing size, and these tools have high operational requirements, increasing maintenance complexity. Operators frequently need to switch between tools of varying specifications when handling bearings of varying sizes, increasing workload and time costs. Utility Model Content

DETAILED DESCRIPTION

[0023] 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.

[0024] The utility model provides Figure 1-5 The device for disassembling the outer ring of a bearing shown in the figure comprises a positioning rod 2 and a fixing frame 4 mounted on the outer wall of the lower end of the positioning rod 2;

[0025] The outer wall of the lower end of the fixing frame 4 is fixedly connected with a bottom ring 6;

[0026] The circular inner wall of the bottom ring 6 is fixedly connected to a connecting rod 13, and a plurality of balls 12 are arranged inside the connecting rod 13. An adjusting bolt 5 is arranged on the upper side of the connecting rod 13. Structural rods 9 are arranged inside the connecting rod 13 and close to the left and right sides respectively to abut the inner wall of the bearing. When the outer ring of the bearing is disassembled, the bottom ring 6 can be moved to the inside of the outer ring of the bearing by holding the positioning rod 2, and then the adjusting bolt 5 is rotated with the help of external fastening tools to move toward the inside of the connecting rod 13. When the adjusting bolt 5 moves toward the inside of the connecting rod 13, it will push the ball 12 to make the structural rod 9 move outward and abut against the inner wall of the outer ring of the bearing. The hammer sleeve 3 is repeatedly moved on the positioning rod 2 and exerts up and down impact force, and the inertia force is used to remove the outer ring of the bearing evenly and strongly.

[0027] like Figure 3 and Figure 4 As shown, a movable groove 11 is opened at the center of the connecting rod 13 and runs through the left and right sides. A retaining spring 10 is fixedly connected between the two structural rods 9 and the upper and lower inner walls of the movable groove 11 to limit the position of the structural rod 9.

[0028] The movable groove 11 limits the storage position of the multiple balls 12, and at the same time limits the movement direction of the multiple balls 12 after being pushed by the adjusting bolt 5. The retaining spring 10 prevents the balls 12 and the structural rod 9 from falling off during operation, ensuring the safety and reliability of the disassembly process.

[0029] like Figure 2 and Figure 4As shown, the positioning rod 2 is sleeved with a hammer sleeve 3, and the upper end outer wall of the connecting rod 13 is provided with a threaded hole opening upward.

[0030] The hammer sleeve 3 strikes the body by moving up and down, generating sufficient inertial force to disassemble the bearing. The threaded hole provided on the outer wall of the upper end of the connecting rod 13 can be screwed into the adjusting bolt 5 to limit the position of the adjusting bolt 5 itself during the adjustment process and when not adjusted.

[0031] like Figure 1 and Figure 2 As shown, rubber pads 7 are provided on the upper and lower outer walls of the hammer sleeve 3, and handles 8 are fixedly connected to the left and right outer walls of the hammer sleeve 3 to assist the hammer sleeve 3 to move up and down under the action of external force. Multiple buffer holes 15 are equidistantly provided inside the two rubber pads 7, and buffer grooves 14 are provided on the left and right circular outer walls of the multiple buffer holes 15.

[0032] When the hammer sleeve 3 moves up and down, it can collide with the gear handle 1 and the fixing frame 4 through the rubber pad 7, reducing the noise of the hammer sleeve 3 when it hits the gear handle 1 and the fixing frame 4. In addition, during the collision, the buffer hole 15 and the buffer groove 14 opened inside the rubber pad 7 can alleviate the impact force during the collision and reduce the damage rate of the rubber pad 7.

[0033] like Figure 3 As shown, when the adjusting bolt 5 is screwed downward, it drives the two structural rods 9 to move to the left and right sides respectively. The adjusting bolt 5 is set between the multiple balls 12.

[0034] When the adjusting bolt 5 moves downward, it pushes the balls 12 on the left and right sides to move to the left and right respectively, thereby driving the structural rod 9 to move in the same way and stretching the retaining spring 10. When the adjusting bolt 5 moves upward, the multiple balls 12 and the structural rod 9 are reset under the rebound force of the retaining spring 10.

[0035] like Figure 1 As shown, the outer wall of the upper end of the positioning rod 2 is fixedly connected to the gear lever 1, and the fixing frame 4 is an inverted U-shape.

[0036] By setting the stop handle 1, a gripping position can be provided for the staff, and when the hammer sleeve 3 moves up and down, the moving distance of the hammer sleeve 3 can be limited. The fixing frame 4 is an inverted U-shape and can be stably connected to the bottom ring 6 by welding to maintain the stability of the connection with the bottom ring 6.

[0037] The implementation principle of this embodiment is: when disassembling the outer ring of the bearing, the positioning rod 2 can be held to move the bottom ring 6 to the inside of the outer ring of the bearing, and then with the help of external fastening tools, the adjusting bolt 5 is rotated and moved toward the inside of the connecting rod 13. When the adjusting bolt 5 moves toward the inside of the connecting rod 13, it will push the ball 12 to make the structural rod 9 move outward and abut against the inner wall of the outer ring of the bearing. The hammer sleeve 3 is repeatedly moved on the positioning rod 2 and exerts up and down impact force, and the inertia force is used to evenly and strongly remove the outer ring of the bearing.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
