Description
Technical Field
[0001] The utility model relates to the technical field of bearing disassembly devices, in particular to a motor bearing quick-disassembly device. Background Art
[0002] The current workflow for motor bearings relies on the traditional, purely manual disassembly method. This method presents numerous challenges. For example, manual bearing removal relies on simple tools, such as hammering the bearings little by little. This requires prolonged bending or forceful striking, which is physically demanding and a significant test of the worker's stamina. Furthermore, it wastes considerable time and results in extremely low work efficiency, making it difficult to meet the demands of daily production.
[0003] Generally speaking, in terms of manpower input, removing a motor bearing in a typical work scenario requires the participation of one or two experienced workers. In terms of working time, these workers take about an hour to complete the task. Due to the inherent limitations of manual operation, manual bearing removal is extremely inefficient.
[0004] With the growing demand for motor repair and disassembly, this inefficient manual operation is no longer sufficient. When production schedules are tight or the motor repair workload is high, this can become a bottleneck, significantly slowing down the entire process. This not only increases costs but can also negatively impact the smooth implementation of subsequent repair plans. Therefore, a motor bearing quick-release device is urgently needed that can significantly improve disassembly efficiency and shorten the time spent on bearing removal during the entire motor repair process. Utility Model Content
[0005] The purpose of the utility model is to provide a motor bearing quick-disassembly device, which can replace manual bearing removal and reduce labor intensity. The bearing is clamped by the bearing clamping grooves that abut against the inner ends of the bearing in opposite directions on both sides. The jack is placed between the device connecting plate and the shaft end. The device connecting plate is pushed by the jack to pull down the bearing, thereby improving the disassembly efficiency.
[0006] The above technical objectives of the present invention are achieved through the following technical solutions:
[0007] A motor bearing quick-release device includes a device connecting plate, one side of which is vertically connected to two connecting columns, and the other ends of the connecting columns are respectively vertically connected to two slide rail connecting rods. The two slide rail connecting rods are arranged in parallel and connected to two oppositely arranged bearing baffles. The bearing baffles are respectively connected to the corresponding ends of the two slide rail connecting rods and slide along them.
[0008] The bearing baffles are provided with bearing slots on one side close to each other, and are respectively abutted against the inner ends of the bearings on opposite sides through the bearing slots; a space is left between the two connecting columns for placing a jack, one end of the jack abuts against the inner side of the device connecting plate, and the other end abuts against the shaft end, so that the bearing is removed from the shaft end.
[0009] By adopting the above technical solution, manual disassembly of bearings can be replaced. The bearing slots are respectively abutted against the inner ends of the bearings in opposite directions on both sides to clamp the bearings. The jack is placed between the device connecting plate and the shaft end. The device connecting plate is pushed by the jack to pull the bearing off the shaft end, thereby improving the disassembly efficiency.
[0010] Furthermore, the bearing slot is configured to be arc-shaped or V-shaped.
[0011] By adopting the above technical solution, the arc-shaped or V-shaped bearing slot can improve the versatility for bearings of different specifications.
[0012] Furthermore, the two bearing slots are assembled into a circle, which is smaller than the outer circle of the bearing.
[0013] By adopting the above technical solution, the circular bearing slot can better adapt to the shape of the bearing, facilitate the clamping of the bearing, ensure that the bearing can be completely clamped, the bearing can be smoothly disassembled, and the stability of disassembly is improved.
[0014] Furthermore, one side of the bearing baffle is connected to a sliding block, a through hole is provided in the sliding block, and the sliding block is sleeved on the slide rail connecting rod through the through hole.
[0015] By adopting the above technical solution, the sliding of the bearing baffle along the slide rail connecting rod is realized, which is used to adjust the baffle opening. The device can realize the disassembly of various motor bearings by adjusting the sliding of the bearing baffle.
[0016] Furthermore, the connecting column and the slide rail connecting rod are both round steel connecting rods.
[0017] By adopting the above technical solution, the processing of raw materials is facilitated.
[0018] Furthermore, the connecting plate of the device is connected to a thickened crossbeam at a side away from the connecting column, and the position of the thickened crossbeam corresponds to the connecting position of the two connecting columns and / or the abutting position of the jack.
[0019] By adopting the above technical solution, the strength of the corresponding position of the device connecting plate is strengthened, ensuring that the beam will not break under the action of the jack, thereby improving the stability of the device when the jack is working.
[0020] Furthermore, bearing slots of different sizes are respectively provided on opposite sides of the bearing baffle.
[0021] By adopting the above technical solution, it is convenient to install the bearing baffle in another direction to adapt to other bearing specifications, thereby reducing the cost of use.
[0022] Furthermore, the outer side of the thickened beam is connected with a device lifting lug.
[0023] By adopting the above technical solution, the hoisting and use of the device is facilitated.
[0024] In summary, the present invention has the following beneficial effects:
[0025] It can replace manual bearing removal. The bearing slots are respectively against the inner end of the bearing in opposite directions to clamp the bearing. The jack is placed between the device connecting plate and the shaft end. The jack pushes the device connecting plate to pull the bearing off the shaft end, which improves the removal efficiency.

[0033] like Figure 1 As shown, the bearing baffle 5 can be moved to abut against each other, so that the two arc-shaped slots are combined into a circle. It can also be just two inferior arcs and moved to both sides of the inner end of the bearing. The above-mentioned arc-shaped slot can also be set to a V-shaped shape or other shapes that are convenient for clamping on the inner side of different bearings.
[0034] The arc or V-shaped bearing slot 6 can improve the versatility for bearings of different specifications, and the two bearing slots 6 are combined into a circle smaller than the outer circle of the bearing to better adapt to the shape of the bearing and improve the stability of disassembly.
