Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a self-lubricating bearing. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearings can be divided into rolling bearings and sliding bearings. Rolling bearings need to be lubricated and sealed to ensure the normal operation of the bearings. Therefore, a self-lubricating bearing is required to ensure the normal operation of the bearings. However, the existing devices still have certain defects when used, such as:

[0003] When the device is in use, the bearing will consume lubricating oil faster during high-speed operation. At this time, the friction generated by the bearing will increase, causing the bearing to generate a large amount of heat. Ordinary devices cannot automatically add lubricating oil during the operation of the bearing, which can easily cause the bearing to deform and wear due to excessive temperature during operation, resulting in a reduction in the service life of the bearing. Utility Model Content

[0004] The utility model aims to solve the above-mentioned problem and proposes a self-lubricating bearing, which improves the problem that the existing self-lubricating bearings cannot be easily refueled during operation.

[0006] The automatic oiling structure comprises a telescopic rod, a baffle plate and a limit block. The bearing seat is provided with a limit block inside. The limit block has a baffle plate inside, and the side of the baffle plate is provided with a telescopic rod.

[0007] Preferably, the telescopic rod passes through the limiting block, an oil storage tank is arranged at the upper end of the bearing seat, a filter plate is arranged on the side of the oil storage tank, and the filter plate is slidably connected to the oil storage tank.

[0015] 1. Through the setting of temperature sensor, oil storage tank, telescopic rod, baffle plate, oil pipe and filter plate, when the device is in use, the temperature generated during the operation of the bearing is first monitored by the SHT30 temperature sensor. When the bearing generates a large amount of temperature due to the increase of friction caused by the depletion of lubricating oil, the temperature sensor detects that the temperature is too high and transmits a signal to trigger the extension of the telescopic rod. At this time, the telescopic rod pushes the baffle plate to one side to move the surface with holes to the top of the oil pipe, and filters the impurities in the lubricating oil through the filter plate to prevent impurities from entering the bearing and causing wear to the bearing. Then the lubricating oil inside the oil storage tank passes through the filter plate into the inside of the limit block, and then passes through the holes on the surface of the baffle plate into the inside of the oil pipe, and passes through the outer ring of the bearing into the inside of the bearing to add lubricating oil to the bearing for lubrication, so that the bearing can be automatically added with lubricating oil during the operation of the bearing to prevent the bearing from being worn and deformed due to excessive temperature during the operation of the bearing, thereby increasing the service life of the bearing.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-6 As shown, a self-lubricating bearing comprises a bearing seat 1, a fixing ring 2, a heat-conducting ring 13 and a bearing outer ring 12: the fixing ring 2 is arranged on the side of the bearing seat 1, the heat-conducting ring 13 is arranged on the inner wall of the bearing seat 1, the bearing outer ring 12 is arranged inside the bearing seat 1, and the automatic oiling structure 24 is arranged inside the bearing seat 1;

[0025] The automatic oiling structure 24 includes a telescopic rod 22, a baffle plate 21 and a limit block 16. The bearing seat 1 is provided with a limit block 16 inside. The limit block 16 has a baffle plate 21 inside, and a telescopic rod 22 is provided on the side of the baffle plate 21.

[0026] When the device is in use, when the lubricating oil inside the bearing is exhausted, the friction of the bearing increases, causing the temperature of the bearing to increase. At this time, the temperature is monitored by the SHT30 model temperature sensor 17. When the temperature is too high, the temperature sensor 17 transmits an electrical signal to the telescopic rod 22, and drives the telescopic rod 22 to push out to one side through electricity, so that the telescopic rod 22 pushes the baffle plate 21 to move to one side, so that the half with holes on the surface of the baffle plate 21 moves to the top of the oil pipe 20, and then the lubricating oil inside the oil storage tank 11 passes through the holes into the inside of the oil pipe 20, and enters the inside of the bearing outer ring 12 and the bearing inner ring 14, so as to achieve the purpose of automatic lubrication during the operation of the bearing, so that the bearing can operate normally to reduce the temperature. At this time, when the temperature sensor 17 detects that the temperature has dropped, the telescopic rod 22 contracts to move the half of the baffle plate 21 surface without holes to the top of the oil pipe 20, so as to stop refueling the bearing.

[0027] The telescopic rod 22 passes through the limit block 16. The upper end of the bearing seat 1 is provided with an oil storage tank 11. The side of the oil storage tank 11 is provided with a filter plate 19. The filter plate 19 is slidably connected to the oil storage tank 11.

[0028] When the device is in use, impurities in the lubricating oil are filtered through the filter plate 19 to prevent the impurities in the lubricating oil from entering the interior of the bearing, causing wear inside the bearing and reducing the service life of the bearing.

[0029] An observation plate 15 is provided on the side of the oil storage tank 11, and an oil pipe 20 is provided at the lower end of the limit block 16, and the oil pipe 20 passes through the outer ring of the bearing 12;

[0030] When the device is in use, since the observation plate 15 is made of transparent glass, it is possible to observe whether there are impurities such as lubricating oil agglomerates on the surface of the filter plate 19, so that the filter plate 19 can be cleaned to prevent clogging of the filter plate 19, and the lubricating oil passes through the barrier plate 21 into the interior of the oil pipe 20, and then enters the interior of the bearing through the oil pipe 20 for lubrication.

[0031] A connecting ring 3 is provided on the side of the fixing ring 2, and a fixing screw 4 is provided on the side of the connecting ring 3, and the fixing screw 4 is threadedly connected to the fixing ring 2;

[0032] The inner wall of the connecting ring 3 is provided with an isolation block 7, the inner wall of the bearing outer ring 12 is provided with a ball 23, the side of the ball 23 is provided with a bearing inner ring 14, and the isolation block 7 is fitted with the bearing inner ring 14;

[0033] When the device is in use, the connecting ring 3 is fixed inside the fixing ring 2 by screwing the fixing screw 4 into the inside of the fixing ring 2, and the isolation block 7 is allowed to enter the inside of the bearing seat 1 and fit with the bearing inner ring 14 to seal the bearing and the bearing seat 1 to prevent dust from entering the inside of the bearing seat 1 and causing dust to affect the operation of the bearing.

[0034] A sealing ring 18 is provided on the side of the bearing outer ring 12, and a temperature sensor 17 is provided on the side of the heat conducting ring 13;

[0035] A cooling fan 5 is provided on the side of the bearing seat 1, and a battery 6 is provided on the upper end of the cooling fan 5;

[0036] A heat sink 8 is provided on the side of the bearing seat 1, a filter screen 9 is provided inside the heat sink 8, and a vent 10 is provided on the inner wall of the bearing seat 1;

[0037] When the device is in use, first the temperature sensor 17 detects that the temperature is too high, and at this time the automatic refueling structure 24 is triggered to refuel the bearing. After the refueling is completed, the temperature sensor 17 continues to transmit a signal to the cooling fan 5 to turn on the cooling fan 5 to blow air to the outside to discharge the hot air inside the bearing seat 1, and to make the heat sink 8 generate suction to suck the cold air from the outside into the bearing seat 1 to cool and dissipate heat, and to filter the dust in the air through the filter 9 to prevent dust from entering the inside of the bearing seat 1.

[0038] When the utility model is in use, first, when the bearing is in operation, the heat dissipation block 8 can be used to dissipate the temperature generated by the bearing during operation. Then, when the lubricating oil is exhausted and the friction force increases, the bearing will generate a large amount of heat, and the heat dissipation block 8 cannot completely dissipate the heat. At this time, the temperature sensor 17 detects that the temperature is too high, and first transmits a signal to the telescopic rod 22, so that the telescopic rod 22 is driven by electricity to push the baffle plate 21 to move to one side, so that the half with the hole is located above the oil pipe 20, and then the lubricating oil in the oil storage tank 11 passes through the baffle plate 21 into the oil pipe 20, and enters the bearing. The oiling is then completed, and the telescopic rod 22 contracts to move the half of the baffle plate 21 without holes to the inside of the oil pipe 20 to stop oiling the inside of the bearing. Then the temperature sensor 17 transmits a signal to turn on the cooling fan 5, and the cooling fan 5 generates suction to absorb and discharge the heat inside the bearing seat 1, and the heat sink 8 generates suction to suck the outside cold air into the inside of the bearing seat 1, so as to quickly dissipate the heat generated by the bearing and prevent the bearing from deforming and wearing due to high temperature during operation.

[0039] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
