Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a split bearing. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. A bearing consists of an outer ring, an inner ring, a support frame, steel balls, and a sealing cover. When using a bearing, the outer ring is fixed to the machine tool, and then the shaft is fixed to the inner ring. When the shaft rotates, the inner ring rotates with the help of the support frame and steel balls, while the sealing cover ensures the internal sealing of the bearing.

[0003] The inventor discovered in his daily work that when bearings are used on machine tools, they need to be inspected after a period of use. When the steel balls inside the bearing are damaged and need to be replaced, workers need to use a pry bar to pry out the steel balls, which makes the inspection process very cumbersome and may easily cause damage to the inner and outer rings of the bearing. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in actual use, when machine tool bearings need to be repaired after a period of use, and the steel balls inside the bearing need to be replaced due to damage, workers need to use a pry bar to pry out the steel balls, which makes the repair process very cumbersome and may easily cause damage to the inner and outer rings of the bearing. Therefore, an overheat-proof split machine tool bearing is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an overheat-resistant split-type machine tool bearing, comprising an outer ring and an inner ring, wherein a support frame, steel balls, and a sealing cover are provided between the outer ring and the inner ring, a disassembly assembly is provided on the left side of the outer ring, and a heat dissipation assembly is provided on the right side of the outer ring, wherein the disassembly assembly includes a disassembly cover provided on the left side of the outer ring, and a plurality of evenly distributed fixing rods are fixedly connected to the right side of the disassembly cover, and a plurality of evenly distributed fixing grooves are provided on the side of the outer ring near the disassembly cover, and locking blocks are slidably connected to both sides of the inner wall of the fixing rods.

[0006] The effect achieved by the above components is as follows: by setting up the disassembly assembly, when it is necessary to replace the steel balls in the machine tool bearing, the pulling mechanism can be used to completely retract the locking blocks on both sides of the fixing rod, so that it is completely separated from the fixing groove. Then, the disassembly cover is dragged to separate the outer ring, thereby separating it from the steel ball. Then, the outer ring is pulled to separate it from the steel ball, and then the steel ball can be replaced. This makes maintenance as convenient as possible and reduces damage to the inner and outer rings.

[0007] Preferably, a spring is fixedly connected between the two locking blocks, and the spring is located inside the fixing rod.

[0008] The effect achieved by the above components is to reset the locking block by setting a spring.

[0009] Preferably, a pull rope is fixedly connected between the two locking blocks, and the pull rope passes through the fixing rod and the disassembly cover.

[0010] The effect achieved by the above components is that pulling the rope causes the locking blocks on both sides of the fixing rod to retract completely.

[0011] Preferably, a first magnetic sheet is fixedly connected to the right side of the fixing rod, and a second magnetic sheet is fixedly connected to the inner wall of the fixing groove.

[0012] The effect achieved by the above components is that, by setting the first magnetic plate and the second magnetic plate, the first magnetic plate and the second magnetic plate attract each other when they are close together, thereby assisting in limiting the fixed rod.

[0013] Preferably, the heat dissipation assembly includes an air inlet inside the outer ring, a plurality of evenly distributed air outlets on one side of the inner wall of the air inlet, an air inlet head for an external air pipe fixedly connected to the left side of the outer ring, and an air outlet hole on one side of the detachable cover.

[0014] The effect achieved by the above components is as follows: when it is necessary to prevent the bearing from overheating during operation, the air pump and air pipe are fixed so that the gas enters the air inlet through the air inlet head, and then blows into the bearing from the air outlet, and finally comes out through the air outlet hole, thereby dissipating heat from the bearing and thus preventing the bearing from overheating.

[0015] Preferably, the inner wall of the air outlet is provided with a one-way valve.

[0016] The effect achieved by the above components is that by setting a one-way valve, the gas in the vent can flow out, while external fluids cannot enter, thereby preventing dust from entering the bearing.

[0017] Preferably, one side of the outer ring is fixedly connected to a plurality of identical fins, and the plurality of fins are evenly distributed on the outer ring.

[0018] The effect achieved by the above components is to assist in heat dissipation of the bearing by setting multiple fins.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] In this invention, by setting up a disassembly assembly, when it is necessary to replace the steel balls inside the machine tool bearing, the pulling mechanism causes the locking blocks on both sides of the fixing rod to retract completely, thus completely separating them from the fixing groove. Then, the disassembly cover is dragged to separate the outer ring, thereby separating it from the steel ball. Then, the outer ring is pulled to separate it from the steel ball, and the steel ball can be replaced. This makes maintenance as convenient as possible and reduces damage to the inner and outer rings. It solves the problem that when machine tool bearings need to be maintained after a period of use, and the steel balls inside the bearing are damaged and need to be replaced, workers need to use a pry bar to pry out the steel balls, which makes the maintenance process very cumbersome and may easily damage the inner and outer rings of the bearing.

[0026] Reference Figure 1 As shown, this utility model provides a technical solution: an overheat-resistant split machine tool bearing includes an outer ring 1 and an inner ring 4. A support frame 5, steel balls 6, and a sealing cover 7 are provided between the outer ring 1 and the inner ring 4. A disassembly assembly 2 is provided on the left side of the outer ring 1, and a heat dissipation assembly 3 is provided on the right side of the outer ring 1.

[0027] The following section will explain the specific settings and functions of disassembly component 2 and heat dissipation component 3.

[0028] Reference Figure 2As shown in this embodiment: the disassembly assembly 2 includes a disassembly cover 21 located on the left side of the outer ring 1. Multiple evenly distributed fixing rods 22 are fixedly connected to the right side of the disassembly cover 21. Multiple evenly distributed fixing grooves 24 are opened on the side of the outer ring 1 near the disassembly cover 21. Locking blocks 23 are slidably connected to both sides of the inner wall of the fixing rods 22. By setting up the disassembly assembly 2, when it is necessary to replace the steel ball 6 inside the machine tool bearing, the locking blocks 23 on both sides of the fixing rod 22 are completely retracted by the pulling mechanism, completely separating from the fixing grooves 24. Then, the disassembly cover 21 is dragged to separate, thus separating the outer ring 1. Next, the outer ring 1 is pulled to separate from the steel ball 6, and then the steel ball 6 is replaced, thereby maximizing the efficiency of the process. It facilitates maintenance and reduces damage to the inner ring 4 and outer ring 1. A spring 27 is fixedly connected between the two locking blocks 23. The spring 27 is located inside the fixing rod 22. By setting the spring 27, the locking blocks 23 are reset. A pull rope 28 is fixedly connected between the two locking blocks 23. The pull rope 28 passes through the fixing rod 22 and the disassembly cover 21. Pulling the pull rope 28 makes the locking blocks 23 on both sides inside the fixing rod 22 completely retract. A first magnetic plate 26 is fixedly connected to the right side of the fixing rod 22. A second magnetic plate 25 is fixedly connected to the inner wall of the fixing groove 24. By setting the first magnetic plate 26 and the second magnetic plate 25, the first magnetic plate 26 and the second magnetic plate 25 attract each other when they are close together, thereby assisting in limiting the fixing rod 22.

[0029] Reference Figure 3 and Figure 4 As shown in this embodiment: the heat dissipation component 3 includes an air inlet 31 opened inside the outer ring 1. Multiple evenly distributed air outlets 33 are opened on one side of the inner wall of the air inlet 31. An air inlet head 32 with an external air pipe is fixedly connected to the left side of the outer ring 1. An air outlet 34 is opened on one side of the disassembly cover 21. When it is necessary to prevent the bearing from overheating during operation, the air pump and the air pipe are fixed so that the gas enters the air inlet 31 through the air inlet head 32, and then blows into the bearing from the air outlet 33. Finally, the gas emerges from the air outlet 34, thereby dissipating heat from the bearing and preventing the bearing from overheating. A one-way valve 35 is provided on the inner wall of the air outlet 34. By setting the one-way valve 35, the gas in the air outlet 34 can flow out, and external fluids cannot enter, thereby preventing dust from entering the bearing. Multiple identical fins 36 are fixedly connected to one side of the outer ring 1. The multiple fins 36 are evenly distributed on the outer ring 1. By setting multiple fins 36, heat dissipation of the bearing is assisted.

[0030] Working principle:

[0031] When using the bearing, the outer ring 1 is fixed to the machine tool, and then the shaft is fixed to the inner ring 4. When the shaft rotates, the inner ring 4 rotates with the help of the support frame 5 and the steel balls 6. Simultaneously, the sealing cover 7 ensures the internal sealing of the bearing. When it is necessary to replace the steel balls 6 inside the machine tool bearing, the worker pulls the pull rope 28, causing the locking blocks 23 on both sides of the fixing rod 22 to retract completely, separating them from the fixing groove 24. Then, the disassembly cover 21 is dragged to separate the outer ring 1. Next, the outer ring 1 is pulled to separate it from the steel balls 6, and then the steel balls 6 are replaced. This method facilitates maintenance and reduces damage to the inner ring 4 and outer ring 1. A spring 27 is also included to ensure proper functioning. The locking block 23 is reset. By setting the first magnetic plate 26 and the second magnetic plate 25, the first magnetic plate 26 and the second magnetic plate 25 attract each other when they are close, thereby assisting in limiting the fixing rod 22. When it is necessary to prevent the bearing from overheating during operation, the air pump and the air pipe are fixed so that the gas enters the air inlet 31 through the air inlet head 32, and then blows into the bearing through the air outlet 33. Finally, the gas emerges from the air outlet 34, thereby dissipating heat from the inside of the bearing and preventing the bearing from overheating. By setting the one-way valve 35, the gas in the air outlet 34 can flow out, and the external fluid cannot enter, thereby preventing dust from entering the bearing. By setting multiple fins 36, heat dissipation of the bearing is assisted.
