In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0034] In automated production equipment, especially in the lifting wheel mechanism of the bottle washing machine in the pharmaceutical filling industry, when regularly lubricating the bearings therein, it is usually necessary to first remove the parts located above the bearings, and then lubricate the bearings. This is not only laborious, but also a waste of work time. In addition, for the oil seal above the bearing, multiple disassemblies will affect the sealing reliability, which may lead to the risk of oil leakage.

[0035] To solve the above problems, see Figure 1 This embodiment provides a bearing assembly. The bearing assembly includes a transmission shaft 1 and a bearing 2, wherein the bearing 2 is sleeved on the transmission shaft 1, and the transmission shaft 1 is provided with an oil filling port, an oil outlet, and an oil guide channel 11 connecting the oil filling port and the oil outlet, wherein the oil outlet at least partially faces the bearing 2, so that lubricating oil can enter the bearing 2 from the oil outlet.

[0036] This bearing assembly can be applied to various automated production equipment. When the bearing 2 needs to be lubricated, it is not necessary to disassemble all the parts above the bearing 2. It is only necessary to disassemble the parts above the oil filling port, and then use the oiling device to inject lubricating oil into the oil filling port. The lubricating oil flows into the oil guide channel 11 along the oil filling port, and then flows to the oil outlet through the oil guide channel 11. The lubricating oil flows to the bearing 2 along the oil outlet, thus achieving the purpose of lubricating the bearing 2. This bearing assembly can reduce the number of parts that need to be disassembled on the equipment when refueling, improve the convenience of refueling, save a lot of manpower and time, and can better ensure the overall sealing reliability of the production equipment.

[0037] Since the lubricating oil needs to flow from the oil outlet into the bearing 2, and the bearing 2 is sleeved on the transmission shaft 1, the oil filling port needs to be arranged on the outer peripheral surface of the transmission shaft 1 and at least partially facing the bearing 2. In this embodiment, the oil filling port and the oil outlet are arranged on the outer peripheral surface of the transmission shaft 1 at intervals along the axis of the transmission shaft 1; in other embodiments, the oil filling port can also be arranged on the end surface of the transmission shaft 1, and the position of the oil filling port can be flexibly arranged according to specific needs, and is not limited to this.

[0038] In this embodiment, the upper end of the oil outlet is higher than the upper end surface of the bearing 2, and the lower end of the oil outlet is located between the upper end surface and the lower end surface of the bearing 2. This arrangement can ensure that the lubricating oil can smoothly enter the interior of the bearing 2 and fully lubricate it; because the upper end of the oil outlet is higher than the upper end surface of the bearing 2, a certain pressure difference can be formed to prevent the lubricating oil from leaking out of the bearing 2 under the action of centrifugal force.

[0039] It should be noted that the oil guide channel 11 can be arranged in a straight line or in a curve, and there is no limitation on its specific structure, and it can be flexibly arranged according to specific needs.

[0040] In this embodiment, if Figure 1 As shown, the oil guide channel 11 includes a first channel 111 opened along the radial direction of the transmission shaft, a second channel 112 opened along the axial direction of the transmission shaft, and a third channel 113 opened along the radial direction of the transmission shaft. The first channel 111 and the third channel 113 are connected at the oil filling port and the oil outlet, respectively. It should be noted that, in order to facilitate processing, the second channel 112 passes through one end of the transmission shaft 1, and then a plugging member is used to block its opening to prevent the lubricating oil from flowing out of the opening, causing the lubricating oil to leak. Continue reading Figure 1 In this embodiment, the first channel 111 includes a first end and a second end, the first end is provided with an oil injection port, the second end is connected to the second channel 112, and the first end is higher than the second end. That is to say, at this time, the first channel 111 is inclined upward from the axis to the outer surface of the shaft as a whole, and when the lubricating oil is injected from the oil injection port, it can flow smoothly into the second channel 112 under the action of gravity to prevent oil accumulation.

[0041] Similarly, in this embodiment, the third channel 113 includes a third end and a fourth end, the third end is provided with an oil outlet, and the fourth end is connected to the second channel 112. That is to say, at this time, the third channel 113 is inclined downward from the axis to the outer surface of the shaft as a whole, and when the lubricating oil flows from the second channel 112 to the fourth end, it can smoothly flow to the oil outlet under the action of gravity, so that the lubricating oil flows to the bearing 2.

[0042] For more details, see Figure 1 The bearing assembly also includes an oil nozzle 3, which is threadedly connected to the oil filling port. The end of the oil nozzle 3 away from the oil filling port can be connected with a refueling device. When refueling and lubrication are needed, the refueling device can be connected to the oil nozzle 3, which can ensure that the lubricating oil can smoothly enter the oil filling port during refueling, making the entire oil filling process simpler and more convenient.

[0043] See also Figure 2This embodiment also provides a lifting wheel mechanism, including the above-mentioned bearing assembly, lifting station 4 and lifting cam 5, the transmission shaft 1 is sequentially inserted through the lifting station 4 and the lifting cam 5, the transmission shaft 1 is fixedly connected to the lifting station 4 and the oil injection hole 12 is located higher than the lifting station 4, and the bearing 2 is located between the transmission shaft 1 and the lifting cam 5. When refueling the lifting wheel mechanism, the bearing 2 can be refueled and lubricated without removing the lifting station 4, which improves the convenience of refueling, saves a lot of manpower and time, and can better ensure the overall sealing reliability of the production equipment.

[0044] In this embodiment, the bearing 2 is a tapered roller bearing 2, which can withstand radial and circumferential combined loads dominated by radial loads, has strong load-bearing capacity, and is not prone to failure. Specifically, a first step is provided on the side of the lifting cam 5 facing the transmission shaft 1, and the outer ring of the tapered roller bearing 2 is placed on the first step of the lifting cam 5, and the inner ring and the transmission shaft 1 are interference fit to achieve synchronous rotation.

[0045] For more details, see Figure 2 , a clamping sleeve 6 is provided between the lifting station 4 and the transmission shaft 1, and the clamping sleeve 6 is configured to fix the transmission shaft 1 and the lifting station 4. The clamping sleeve 6 transmits load by tightening the high-strength bolts to generate pressure and friction between the transmission shaft 1 and the lifting station 4, so as to realize the connection between the lifting station 4 and the transmission shaft 1, so that the lifting station 4 can rotate under the drive of the transmission shaft 1. The clamping sleeve 6 is a keyless connection device commonly used in the prior art, and the present utility model does not elaborate on its structure. It should be noted that in other embodiments, the fixed connection between the lifting station 4 and the transmission shaft 1 can also be achieved by bolts or other fasteners in the prior art, and the present utility model does not limit this.

[0046] Preferably, the lifting wheel mechanism includes a sealing ring 7, which is sleeved on the transmission shaft 1 and abuts against the lifting station 4. It can prevent the lubricating oil from leaking out, and can also prevent splashing water or dust from the outside from invading. Specifically, the transmission shaft 1 is provided with a placement groove along the circumference, and the sealing ring 7 is filled in the placement groove.

[0047] In this embodiment, the material of the sealing ring 7 is silicone rubber, which has good elasticity, toughness, wear resistance, and good sealing performance. In other embodiments, the material of the sealing ring 7 can also be graphite, polytetrafluoroethylene, etc., which is not limited in this embodiment.

[0048] It should be noted that there may be multiple sealing rings 7 arranged at intervals along the axial direction of the transmission shaft 1 to further improve the sealing performance.

[0049] To prevent lubricating oil leakage, continue to refer to Figure 2The lifting wheel mechanism includes an oil seal 8, which is sleeved on the transmission shaft 1 and located above the bearing 2. In this embodiment, the oil seal 8 is a double-lip TC skeleton oil seal 8, which can prevent oil leakage and external dust from falling into the bearing 2. The double-lip TC skeleton oil seal 8 is a commonly used part in the prior art, and the specific structure of the double-lip TC skeleton oil seal 8 is not described in detail in the present utility model.

[0050] Specifically, a second step is provided on the side of the lifting cam 5 facing the transmission shaft 1 , and the second step is located above the first step. The double-lip TC skeleton oil seal 8 is placed on the second step, and its lip surface abuts against the outer surface of the lifting station 4 .

[0051] In order to prevent external dust or splashing water from affecting the lifting station 4 and other structures, and to improve the overall aesthetics of the mechanism, continue to refer to Figure 2 The lifting wheel mechanism includes a cover plate 9, which is arranged on the top of the transmission shaft 1.

[0052] In order to prevent the cover plate 9 from shaking, shifting or even falling off when the transmission shaft 1 rotates, the lifting wheel mechanism further includes a fixing member 10 , which is configured to fix the cover plate 9 to the transmission shaft 1 .

[0053] In the present embodiment, the fixing member 10 is a fixing knob, which includes a connecting portion and a knob portion. The connecting portion passes through the cover plate 9 and the transmission shaft 1 in sequence, and is threadedly connected to the transmission shaft 1. The fixing knob is tightened to make the cover plate 9 abut against the transmission shaft 1. This fixing method is simple to assemble and disassemble. When the bearing 2 needs to be lubricated, it is only necessary to loosen the fixing knob to remove the cover plate 9, and then use the oiling device to add oil to the bearing 2 through the oil nozzle 3. In other embodiments, the fixing member 10 may be a screw or a bolt. It should be noted that in the prior art, any structure that can fix the cover plate 9 on the transmission shaft 1 can be used as the fixing member 10 in this embodiment, and there is no limitation on this.
