It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0034] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0035] In the related art, after the motor is installed in the chassis, a bearing is usually sleeved on the output shaft of the motor, and then the bearing is enclosed in the chassis, and an appropriate amount of lubricating oil is applied to the bearing, so as to reduce the friction generated between the output shaft and the chassis during the operation of the motor and ensure that the output shaft of the motor has a better rotation effect.

[0036] However, the lubricating oil on the bearing will decrease with the increase of the use time, and then the bearing cannot be effectively lubricated during the subsequent use; and when applying lubricating oil to the bearing again, it is necessary to disassemble the chassis to expose the bearing, and then apply the lubricating oil to the bearing, making this process relatively inconvenient.

[0037] Accordingly, the embodiment of the present application provides an installation structure for a bearing. By providing a machine cover, a bearing cover, and a bearing, the machine cover has an oil storage cavity with an open end. The bearing is located within the oil storage cavity. The bearing cover is connected to the machine cover and closes the opening of the oil storage cavity. At least two openable and closable oil delivery channels are provided on the machine cover, and each oil delivery channel connects the oil storage cavity to the outside of the machine cover. After the bearing is used for a long time, only need to inject lubricating oil into the oil delivery channel, and then the lubricating oil will smoothly enter the oil storage cavity under the guidance of the oil delivery channel to lubricate the bearing, thus eliminating the need to remove the chassis, simplifying the operation steps of the bearing lubrication process, improving the lubrication convenience and efficiency. Moreover, when injecting lubricating oil from one of the oil delivery channels, the lubricating oil can also flush out some debris or other impurities in the oil storage cavity from other oil delivery channels, improving the working environment of the bearing and optimizing the bearing lubrication effect, thereby solving the problem of inconvenient lubrication of bearings in the prior art.

[0038] The technical solution of the present utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0039] As Figure 1 and Figure 2 shown, the embodiment of the present application provides an installation structure for a bearing, including a machine cover 100, a bearing cover 200, and a bearing 300 for sleeving on the output shaft 10 of the motor. The machine cover 100 has an oil storage cavity 110 with an open end. The bearing 300 is located within the oil storage cavity 110. The bearing cover 200 is connected to the machine cover 100 and closes the opening of the oil storage cavity 110. At least two openable and closable oil delivery channels are provided on the machine cover 100, and each oil delivery channel connects the oil storage cavity 110 to the outside of the machine cover 100.

[0040] During actual implementation, the motor can be arranged in the chassis, and then the machine cover 100 is sleeved on the output shaft 10 of the motor, and the machine cover 100 is fixed to the chassis by screwing, welding or other means, so as to enclose the motor in the chassis through the machine cover 100, and the output shaft 10 of the motor passes through the machine cover 100 and extends out of the chassis.

[0041] The oil storage cavity 110 is in a ring structure and is adapted to the bearing 300. The oil storage cavity 110 opens towards the side where the motor is located. Of course, the oil storage cavity 110 can also be set in other shapes, which is not limited herein. The bearing 300 is sleeved on the output shaft 10 of the motor, and the bearing 300 is embedded in the oil storage cavity 110, so as to support the rotation of the output shaft 10 of the motor through the bearing 300.

[0042] The bearing cover 200 can be fixed to the side of the machine cover 100 facing the motor by screwing, welding or other means. The bearing cover 200 is sleeved on the motor output shaft 10, and the bearing cover 200 also closes the opening of the oil storage cavity 110 to confine the bearing 300 within the oil storage cavity 110.

[0043] It should be noted that at least two openable and closable oil delivery channels are provided on the machine cover 100. The oil delivery channels communicate the oil storage cavity 110 with the outside of the machine cover 100 so as to inject lubricating oil into the oil storage cavity 110 from the oil delivery channels.

[0044] In actual implementation, by way of example, the oil delivery channels can be drilled on the machine cover 100, or an oil delivery pipe communicating with the oil storage cavity 110 can be additionally provided on the machine cover 100 so that an oil delivery channel is formed inside the oil delivery pipe. Of course, other methods can also be used to make the oil delivery channels, and there is no limitation in this regard. In addition, in other embodiments, the oil delivery channels can also be provided on the bearing cover 200.

[0045] After the bearing 300 has been used for a long time, only need to inject lubricating oil into the oil delivery channels, and then the lubricating oil will smoothly enter the oil storage cavity 110 under the guidance of the oil delivery channels to lubricate the bearing 300, so that there is no need to remove the machine case, simplifying the operation steps of the lubrication process of the bearing 300 and improving the lubrication convenience and efficiency; moreover, when injecting lubricating oil from one of the oil delivery channels, the lubricating oil can also flush out some debris or other impurities in the oil storage cavity 110 from other oil delivery channels, improving the working environment of the bearing 300 and optimizing the lubrication effect of the bearing 300, thus solving the problem of inconvenient lubrication of the bearing 300 in the prior art.

[0046] As Figure 1 shown, in some embodiments, at least one oil delivery channel is an oil inlet channel 400, and at least one oil delivery channel is an oil drain channel 500. One end of the oil inlet channel 400 and one end of the oil drain channel 500 are both located on the side wall of the machine cover 100, and the other end of the oil inlet channel 400 and the other end of the oil drain channel 500 are both communicated with the oil storage cavity 110. The other end of the oil inlet channel 400 and the other end of the oil drain channel 500 are respectively arranged on two opposite end faces of the bearing 300.

[0047] It should be noted that the specific number of the oil delivery channels can be reasonably designed according to actual needs, and there is no limitation in this regard. Among them, at least one oil delivery channel is an oil inlet channel 400, one end of the oil inlet channel 400 communicates with the outer wall of the machine cover 100, and the other end communicates with the oil storage cavity 110; at least one oil delivery channel is an oil drain channel 500, one end of the oil drain channel 500 communicates with the outer wall of the machine cover 100, and the other end communicates with the oil storage cavity 110; the end of the oil inlet channel 400 facing the oil storage cavity 110 and the end of the oil drain channel 500 facing the oil storage cavity 110 are respectively arranged on two opposite end faces of the bearing 300.

[0048] During use, lubricating oil can be injected from the oil inlet passage 400. The lubricating oil will enter the oil storage cavity 110, pass through the bearing 300, and then be output from the oil drain passage 500, so as to achieve the purpose of lubricating the bearing 300. At the same time, it is convenient to flush the debris or other impurities in the oil storage cavity 110 out of the oil drain passage 500, improve the cleanliness of the oil storage cavity 110, and improve the subsequent use effect of the bearing 300.

[0049] Such as Figure 1 shown, in some embodiments, an oil collecting groove 111 is formed in the side wall of the oil storage cavity 110, and the oil collecting groove 111 is arranged circumferentially around the bearing 300.

[0050] Specifically, the oil collecting groove 111 is annular. After the bearing 300 is installed in the oil storage cavity 110, the oil collecting groove 111 is correspondingly arranged on the circumferential side of the bearing 300, and the oil collecting groove 111 extends circumferentially around the bearing 300.

[0051] Thus, part of the lubricating oil in the oil storage cavity 110 will be stored in the oil collecting groove 111, so as to maintain the lubricating effect between the circumferential side of the bearing 300 and the side wall of the oil storage cavity 110 for a long time, and optimize the lubricating effect of the bearing 300.

[0052] Such as Figure 1 shown, in some embodiments, the machine cover 100 is provided with at least two sealing members 600. Each sealing member 600 is correspondingly arranged in each oil delivery passage, and the sealing member 600 closes one end of the oil delivery passage facing the outside of the machine cover 100.

[0053] During the use of the motor, the sealing members 600 can be used to close one end of each oil delivery passage facing the outside of the machine cover 100, so as to ensure the stability of the lubricating oil in the oil storage cavity 110 and the oil delivery passage, and reduce the possibility of lubricating oil leakage.

[0054] Such as Figure 1 and Figure 2 shown, wherein, the sealing member 600 includes a plug body 610. The plug body 610 is detachably connected to the machine cover 100, and the plug body 610 closes one end of the oil delivery passage facing the outside of the machine cover 100.

[0055] Specifically, part of the plug body 610 is inserted and fitted into the oil delivery passage to close the oil delivery passage, and each plug body 610 can be inserted and fitted into the oil inlet passage 400 or the oil drain passage 500.

[0056] In actual implementation, for example, the plug body 610 can be connected to the machine cover 100 by means of threads, or the plug body 610 can be fixed to the machine cover 100 by screws, and there is no limitation on this. Of course, a sealing ring can also be sleeved on the plug body 610. When the plug body 610 is fastened to the machine cover 100, the sealing ring will be clamped between the opening edge of the oil delivery channel and the plug body 610 to improve the sealing effect of the oil delivery channel.

[0057] After the bearing 300 is lubricated, the plug body 610 can be fixed to the machine cover 100 and inserted into the oil delivery channel in a mating manner, so as to close the oil delivery channel and ensure that the lubricating oil is sealed in the oil storage cavity 110.

[0058] As Figure 2 shown, further, the sealing member 600 further includes a filter mesh 620 and a sealing cover 630. The plug body 610 has an oil injection hole 611 that communicates the oil delivery channel with the outside of the machine cover 100. The filter mesh 620 is disposed on the side of the plug body 610 facing the oil delivery channel and covers the oil injection hole 611. The sealing cover 630 is detachably connected to the plug body 610 and is used to close or open the oil injection hole 611.

[0059] Among them, the oil injection hole 611 is disposed inside the plug body 610 and penetrates the plug body 610. When the plug body 610 is inserted into the oil delivery channel in a mating manner, the oil injection hole 611 will communicate the oil delivery channel with the outside of the machine cover 100.

[0060] The filter mesh 620 is installed in the plug body 610 and covers the oil injection hole 611 from the cross-section of the plug body 610, so that the filter mesh 620 has a certain filtering effect on the lubricating oil flowing in the oil injection hole 611.

[0061] The sealing cover 630 can be detachably fixed to one end of the plug body 610 away from the oil delivery channel by screwing, buckling or other means, and the sealing cover 630 closes one end of the oil injection hole 611 away from the oil delivery channel.

[0062] When it is necessary to inject lubricating oil into the oil storage cavity 110, first, the sealing cover 630 can be removed, and lubricating oil can be injected into the oil injection hole 611 to make the lubricating oil enter the oil storage cavity 110 to lubricate the bearing 300. At this time, the filter mesh 620 will play a role and have a certain filtering effect on the injected lubricating oil, reducing the possibility of some impurities entering the oil storage cavity 110 and causing harm to the bearing 300. Second, the plug body 610 can be removed as a whole, and lubricating oil can be directly injected into the oil delivery channel. Thereby, the injection rate of the lubricating oil can be appropriately increased, and it is also convenient to impact the debris in the oil storage cavity 110 and improve the discharge effect of the debris from other oil delivery channels. Therefore, in actual use, different lubricating oil injection methods can be selected according to actual needs, with a wide adaptation range and better use effects.

[0063] As Figure 2As shown, in some embodiments, the plug body 610 is provided with a slot 612. One side of the slot 612 has a socket, and the socket of the slot 612 is located on the side of the plug body 610. The filter screen 620 is inserted into the slot 612. When the plug body 610 is connected to the machine cover 100, the side wall of the oil delivery channel restricts the filter screen 620 within the slot 612.

[0064] Specifically, one end of the plug body 610 facing the oil delivery channel is provided with a slot 612. The slot 612 is opened from the peripheral side of the plug body 610 towards the inside, such that the socket of the slot 612 is located on the peripheral side of the plug body 610, and when the plug body 610 is inserted and mated with the oil delivery channel, the inner wall of the oil delivery channel exactly seals the socket of the slot 612.

[0065] The filter screen 620 is inserted and fixed within the slot 612. And preferably, one end of the filter screen 620 facing the socket is flush with the peripheral wall of the plug body 610, thereby ensuring the stability of the installation and use of the filter screen 620.

[0066] During installation, only need to insert the filter screen 620 into the slot 612, then insert and mate the plug body 610 with the oil delivery channel, and fasten the plug body 610 to the machine cover 100, thus realizing the installation of the plug body 610 and the reinforcement of the filter screen 620, improving the stability of the use of the filter screen 620.

[0067] In other embodiments, the sealing member 600 can also be set as a valve to control the opening and closing of the oil delivery channel through the valve.

[0068] Such as Figure 1 As shown, in some embodiments, a sealing ring 700 is arranged inside the machine cover 100 for sleeving on the motor output shaft 10.

[0069] Wherein, the sealing ring 700 is made of rubber, silica gel or other sealing materials. The sealing ring 700 can also be a rotary sealing ring. The sealing ring 700 is arranged inside the machine cover 100 and sleeved on the motor output shaft 10.

[0070] Thus, the sealing effect of the gap between the motor output shaft 10 and the machine cover 100 is improved through the sealing ring 700, the waterproof performance of the motor output shaft 10 at the machine cover 100 is improved, the possibility of moisture invading into the oil storage cavity 110 from one side of the machine cover 100 is reduced, and at the same time, the possibility of the lubricating oil in the oil storage cavity 110 leaking from one side of the machine cover 100 is reduced.

[0071] Such as Figure 1 As shown, further, a water throwing ring 800 is arranged on the side of the machine cover 100 facing away from the bearing cover 200 for connecting to the motor output shaft 10.

[0072] In the embodiment of the present application, the water throwing ring 800 is sleeved and fixed on the motor output shaft 10, and the water throwing ring 800 is located on the side of the machine cover 100 away from the bearing cover 200.

[0073] When the motor output shaft 10 rotates, it will drive the water throwing ring 800 to rotate, so as to throw water or other liquids away from the surface of the motor output shaft 10 by centrifugal force, reducing the possibility of liquid invading the oil storage cavity 110 from one side of the machine cover 100 and affecting the bearing 300.

[0074] As Figure 1 shown, in some embodiments, an installation groove 120 is provided on the inner surface of the machine cover 100. The side of the installation groove 120 away from the bearing cover 200 has a notch. The sealing ring 700 is embedded in the installation groove 120, and the water throwing ring 800 closes the notch of the installation groove 120.

[0075] An installation groove 120 is formed on the inner surface of the machine cover 100 (i.e., the surface of the machine cover 100 corresponding to the peripheral wall of the motor output shaft 10). The installation groove 120 is annular and extends circumferentially around the motor output shaft 10. The side of the installation groove 120 away from the bearing cover 200 also has a notch, so that the sealing ring 700 can be inserted into the installation groove 120 from the notch. At this time, when the water throwing ring 800 is sleeved and fixed on the motor output shaft 10, the water throwing ring 800 closes the notch of the installation groove 120, thereby restricting the sealing ring 700 in the installation groove 120, ensuring the stability of the installation of the sealing ring 700, simplifying the installation steps of the sealing ring 700, and improving the installation convenience.

[0076] In summary, the embodiment of the present application provides an installation structure of a bearing. When the bearing 300 is used for a long time, only lubricating oil needs to be injected into the oil delivery channel, and then the lubricating oil will smoothly enter the oil storage cavity 110 under the guidance of the oil delivery channel to lubricate the bearing 300, so that there is no need to dismantle the chassis, simplifying the operation steps of the lubrication process of the bearing 300, improving the lubrication convenience and efficiency; and when lubricating oil is injected from one of the oil delivery channels, the lubricating oil can also flush out some debris or other impurities in the oil storage cavity 110 from other oil delivery channels, improving the working environment of the bearing 300 and optimizing the lubrication effect of the bearing 300, thus solving the problem of inconvenient lubrication of the bearing 300 in the prior art.
