However, in the existing lubrication method, the lubricating oil cannot fully lubricate the components above the oil level due to gravity, which can easily lead to temperature increase and accelerated wear. The probability of maintenance and damage is much higher than that of well-lubricated components, which is not conducive to ensuring the normal operation of the device. Utility Model Content

[0009] Furthermore, each stirring blade is provided with a first guide surface on one side along its own thickness direction, and each stirring blade is provided with a second guide surface on the other side along its own thickness direction, and the first guide surface is used to guide the lubricating oil to flow upward through the inner wall of the cavity to the first bearing, and the second guide surface is used to guide the lubricating oil to flow downward into the oil flow channel.

[0010] Furthermore, when the rotating shaft rotates clockwise, the lubricating oil can be driven by each of the first guide surfaces to flow upward along the inner wall of the cavity to the first bearing; and / or,

[0011] When the rotating shaft rotates counterclockwise, the lubricating oil can be driven to flow downward into the oil flow channel through each second guide surface, and then transported to the first bearing through the oil flow channel.

[0012] Furthermore, both ends of the rotating shaft are provided with steps, and the steps can form a mounting section, and the first bearing and the second bearing are both sleeved on the mounting section.

[0013] Furthermore, a cooling channel is provided on a side of the shell away from the oil flow channel, and the cooling channel is extended along the height direction of the shell.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] Example 1

[0036] This embodiment relates to a bearing lubrication structure that can fully lubricate the components above the oil level, thereby ensuring the normal operation of the device. Figure 1 As shown in the figure, the bearing lubrication structure of this embodiment includes a housing 1, a rotating shaft 2 arranged on the housing 1, the rotating shaft 2 extends along the height direction of the housing 1, the upper end of the rotating shaft 2 is provided with a first bearing 3, and the lower end of the rotating shaft 2 is provided with a second bearing 4.

[0037] At the same time, a plurality of stirring blades 21 are provided at intervals along the circumference of the rotating shaft 2 near the second bearing 4. The second bearing 4 and each stirring blade 21 are located below the level of the lubricating oil 5, and each stirring blade 21 is arranged at an angle. When the rotating shaft 2 is driven to rotate, the lubricating oil 5 is transported to the first bearing 3 through each stirring blade 21.

[0038] At this time, as set above, by arranging a stirring blade 21 on the rotating shaft 2, when the rotating shaft 2 is driven to rotate, the lubricating oil 5 can be transported to the first bearing 3 located above the liquid surface of the lubricating oil 5 through the stirring blade 21, so that the first bearing 3 is fully lubricated. At the same time, the second bearing 4 and the stirring blade 21 are immersed in the lubricating oil 5, which can ensure that the second bearing 4 and the stirring blade 21 are fully lubricated, thereby ensuring the normal operation of the device.

[0039] In the specific structure, the inclination angle of each stirring blade 21 (i.e., the angle between each stirring blade 21 and the vertical plane) can be set between 10° and 15°. In specific implementation, the inclination angle of each stirring blade 21 can be set to 10°, thereby effectively increasing the delivery amount of lubricating oil 5 and thereby improving the lubrication efficiency of the first bearing 3. In addition, the stirring blades 21 in this embodiment can be set to four. Of course, in addition to being set to four, corresponding designs and adjustments can also be made according to actual needs, such as five or six.

[0040] Based on the above overall introduction, in this embodiment, as a preferred implementation form, as Figure 1 As shown, the housing 1 is provided with a cavity 11 for containing lubricating oil 5, and an oil flow channel 12 is opened on one side of the housing 1 in the width direction, and the oil flow channel 12 is connected to the cavity 11, and the inner walls of the oil flow channel 12 and the cavity 11 are used to guide the lubricating oil 5 to flow to the first bearing 3.

[0041] The advantage of such an arrangement is that, through the arrangement of the cavity 11 and the oil flow channel 12 , the flow of the lubricating oil 5 can be guided, thereby facilitating ensuring that the lubricating oil 5 can be stably delivered to the first bearing 3 .

[0042] In the specific structure, the oil flow channel 12 is concave in shape and has a conveying section 121 extending along the height direction of the shell 1, and a connecting section 122 connected at both ends of the conveying section 121. Each connecting section 122 extends along the width direction of the shell 1, and the connecting section 122 can connect the conveying section 121 with the cavity 11.

[0043] Specifically, as a preferred embodiment, refer to Figure 1 As shown in the figure, each stirring blade 21 of this embodiment is provided with a first guide surface 211 on one side along its own thickness direction, and each stirring blade 21 is provided with a second guide surface 212 on the other side along its own thickness direction, and the first guide surface 211 is used to guide the lubricating oil 5 to flow upward through the inner wall of the cavity 11 to the first bearing 3, and the second guide surface 212 is used to guide the lubricating oil 5 to flow downward into the oil flow channel 12.

[0044] It can be understood that the stirring blade 21 includes a first guide surface 211 and a second guide surface 212. When the driving shaft 2 is rotated, the lubricating oil 5 can be transported to the first bearing 3 through the guiding action of the first guide surface 211 and the second guide surface 212 respectively, thereby ensuring that the first bearing 3 is fully lubricated and avoiding damage to the first bearing 3.

[0045] Furthermore, in this embodiment, as a preferred implementation form, Figure 1 As shown, when the rotating shaft 2 rotates clockwise, the lubricating oil 5 can be driven to flow upward along the inner wall of the cavity 11 to the first bearing 3 through each first guide surface 211 .

[0046] At the same time, as another preferred embodiment, when the rotating shaft 2 of this embodiment rotates counterclockwise, the lubricating oil 5 can be driven to flow downward into the oil flow channel 12 through each second guide surface 212 and transported to the first bearing 3 through the oil flow channel 12.

[0047] With this arrangement, by driving the rotating shaft 2, it can rotate in two directions respectively, and the lubricating oil 5 can be delivered to the first bearing 3, so that the first bearing 3 can be lubricated in two different ways, which can improve the operability of the device. At the same time, there is no need to add additional devices, which is conducive to cost reduction.

[0048] During specific implementation, the driving shaft 2 rotates clockwise and drives each stirring blade 21 to centrifugally stir the lubricating oil 5. At this time, the lubricating oil 5 can flow upward along the first guide surface 211 and, through the guiding effect of the inner wall of the cavity 11, the lubricating oil 5 is transported to the first bearing 3 to lubricate the first bearing 3. The rising lubricating oil 5 falls back into the cavity 11 under the action of gravity, forming a cycle, effectively ensuring that the first bearing 3 is fully lubricated.

[0049] It should be understood that in other embodiments, the driving shaft 2 rotates counterclockwise and drives each stirring blade 21 to centrifugally stir the lubricating oil 5. At this time, the lubricating oil 5 can flow downward along the second guide surface 212 into the oil flow channel 12. At the same time, when the rotating shaft 2 drives each stirring blade 21 to rotate, the second guide surface 212 can generate downward pressure on the lubricating oil 5, thereby pushing the lubricating oil 5 in the oil flow channel 12 to flow upward to the first bearing 3 through pressure to lubricate the first bearing 3.

[0050] In addition, in this embodiment, as a preferred implementation form, as shown in the figure, steps 22 are provided at both ends of the rotating shaft 2. The steps 22 can form a mounting section, and the first bearing 3 and the second bearing 4 are both mounted on the mounting section. Here, by providing the steps 22 to form the mounting section, the first bearing 3 and the second bearing 4 can be axially positioned. At the same time, the step 22 at the lower end of the rotating shaft 2 can support the rotating shaft 2, and the step 22 at the upper end of the rotating shaft 2 can support the first bearing 3.

[0051] It should be noted that the first bearing 3 and the second bearing 4 of this embodiment can be mounted on the mounting section by means of interference fit. Of course, in addition to the interference fit, other common connection forms such as spline connection, threaded connection, etc. can also be used.

[0052] In addition, in this embodiment, as a preferred implementation form, as shown in the figure, a cooling channel 13 is provided on the side of the housing 1 away from the oil flow channel 12. The cooling channel 13 extends along the height direction of the housing 1. Therefore, by providing the cooling channel 13, the flowing working fluid can readily remove the heat generated by the first bearing 3 and the second bearing 4 during use, thereby ensuring the stability and service life of the device during operation.

[0053] It should be noted that the working fluid in this embodiment can be a coolant product well known to those skilled in the art, such as alcohol, water, etc.

[0054] At the same time, as a preferred embodiment, as shown in the drawings, the bearing lubrication structure of this embodiment further includes a circulation device 6. Here, by providing the circulation device 6, the consumption of the working fluid can be reduced, thereby saving energy.

[0055] Among them, the circulation device 6 includes a circulating water tank 61 arranged on the shell 1, and a liquid inlet pipe 62 and a liquid outlet pipe 63 arranged on the circulating water tank 61, and the liquid inlet pipe 62 is connected to one end of the cooling channel 13, and the liquid outlet pipe 63 is connected to the other end of the cooling channel 13.

[0056] By setting up the circulating water tank 61, the liquid inlet pipe 62 and the liquid outlet pipe 63, the working fluid can enter the cooling channel 13 through the liquid inlet pipe 62 and complete heat exchange with the first bearing 3 and the second bearing 4, and then flow into the circulating water tank 61 again through the liquid outlet pipe 63, thereby ensuring that the first bearing 3 and the second bearing 4 can dissipate heat in time.

[0057] Furthermore, it is worth mentioning that the bearing lubrication structure of this embodiment can also lubricate other components on the rotating shaft 2, such as gears, clutches, etc., through the above design.

[0058] When the bearing lubrication structure of this embodiment is in use, the driving shaft 2 rotates clockwise, which can drive each stirring blade 21 to centrifugally stir the lubricating oil 5 in the clockwise direction, and under the guidance of the first guide surface 211, the lubricating oil 5 flows downward along the inner wall of the shell 1 to the first bearing 3 to lubricate the first bearing 3.

[0059] Furthermore, the rotating shaft 2 can be driven to rotate counterclockwise, which can drive each stirring blade 21 to centrifugally stir the lubricating oil 5 in the counterclockwise direction, so that under the guiding action of the second guide surface 212, downward pressure can be generated, and then the lubricating oil 5 can be pushed into the conveying section 121 through the connecting section 122 at the lower end, and transported to the first bearing 3 through the connecting section 122 at the upper end to lubricate the first bearing 3.

[0060] Example 2

[0061] This embodiment relates to an anchor drilling rig, which is provided with the bearing lubrication structure in the first embodiment.

[0062] The anchor drilling rig of this embodiment, by setting up the bearing lubrication structure in Example 1, drives each stirring blade 21 to rotate clockwise or counterclockwise through the rotating shaft 2, and can transport the lubricating oil 5 to the first bearing 3, fully lubricate the first bearing 3, and increase the service life of the first bearing 3, which is beneficial to ensure the normal operation of the anchor drilling rig.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
