Description

Technical Field

[0001] This utility model belongs to the field of wet grinding mill technology, specifically relating to a highly stable linear rotating device for wet grinding mills. Background Technology

[0002] While the grinding devices in current copper foil production machines can meet the requirements for producing ordinary copper foil, when producing high-performance copper foil, the poor stability of the grinding rollers leads to poor polishing effects, and the surface finish of the cathode rollers fails to meet requirements. This results in copper foil tearing, uneven thickness, and poor surface quality, thus affecting product quality and causing a decrease in the pass rate and production efficiency. Existing technology discloses a linear rotary device for wet grinding mills, publication number CN217097176U. The locking nut and spline sleeve are connected by a reverse thread, making the locking nut less prone to loosening. However, it has been found that the support seat contains a single bearing. When the spline sleeve is subjected to uneven force, the bearing will be damaged, requiring frequent bearing replacement. Moreover, when the bearing wears, even with a reverse thread connection, the locking nut will loosen. Summary of the Invention

[0003] To address the problems mentioned in the background section, the purpose of this invention is to provide a highly stable linear rotating device for wet mills.

[0004] This utility model discloses a highly stable linear rotating device for a wet grinding mill, comprising a support base, end cap one, spline sleeve, end cap two, pulley, spline shaft, bearings, grease fitting, and anti-loosening nut body. Bearing mounting holes are provided on both the front and rear sides of the support base, and bearings are fixedly installed in both bearing mounting holes. A grease fitting threaded hole is provided at the top of the support base, with the upper end of the threaded hole connected to the grease fitting via a thread, and the lower end connected to an oil reservoir. The oil reservoir is connected to both bearing mounting holes. The spline sleeve is fixedly connected to the inner rings of the two bearings. A pulley is fixedly connected to the right end of the spline sleeve. The spline shaft is movably connected to the spline groove inside the spline sleeve. Both ends of the support base are fixedly connected to end cap one and end cap two via bolts. A connecting thread is provided on the outer side of the spline sleeve; the connecting thread is a reverse thread, and the anti-loosening nut body is connected to the reverse thread of the spline sleeve.

[0005] As a preferred embodiment: the outer side wall of the anti-loosening nut body is uniformly provided with threaded holes, and a set screw is fixedly connected inside the threaded hole, with the head of the set screw contacting the outer side wall of the spline sleeve.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows: It achieves stable support for the spline sleeve through a support base, end cap one, spline sleeve, end cap two, pulley, spline shaft, bearing, grease fitting, and anti-loosening nut body, ensuring even stress distribution on the bearing and reducing the likelihood of damage. Simultaneously, it enables bearing lubrication, extending its service life, and the anti-loosening nut body prevents the spline sleeve from loosening. Specific advantages include: I. This utility model improves the uniformity of force on the spline sleeve by using two bearings, making the spline sleeve less prone to shaking.

[0007] Second, this utility model uses an oil filler nozzle to supply oil to the oil storage tank, which facilitates lubrication of the bearing and improves the service life of the bearing.

[0008] Third, this utility model uses an anti-loosening nut body to prevent the spline sleeve from loosening, making the spline sleeve less likely to fall off and improving the firmness of the fixation. Attached Figure Description

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. The structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0013] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0014] Specific implementation method one: Combining Figures 1 to 5 The following is a description of this specific embodiment, which adopts the following technical solution: It includes a support base 1, end cap 1 2, spline sleeve 3, end cap 2 4, pulley 5, spline shaft 6, bearing 7, grease fitting 8, and anti-loosening nut body 9. Bearing mounting holes 1-2 are provided on both the front and rear sides of the support base 1. Bearings 7 are fixedly installed in both bearing mounting holes 1-2, and the two bearings 7 can effectively support the spline sleeve 3, making it less prone to damage due to uneven force. A grease fitting threaded hole 1-1 is provided at the top of the support base 1. The upper end of the grease fitting threaded hole 1-1 is connected to the grease fitting 8 via a thread, and the lower end of the grease fitting threaded hole 1-1 is connected to the oil reservoir 1-3. The oil reservoir 1-3 is connected to both bearing mounting holes 1-2. 2. The oil nozzle 8 can inject grease or other lubricants, which can lubricate the bearings in the oil reservoir 1-3, preventing the bearings 7 from wearing or being damaged due to lack of oil. The spline sleeve 3 is fixedly connected to the inner rings of the two bearings 7. The right end of the spline sleeve 3 is fixedly connected to the pulley 5. The spline shaft 6 is movably connected to the spline groove inside the spline sleeve 3. The two ends of the support base 1 are fixedly connected to the end cover 1 2 and end cover 2 4 by bolts, respectively. The end cover 1 2 and end cover 2 4 can fix the two bearings 7. The outer side of the spline sleeve 3 is provided with a connecting thread, which is a reverse thread. The anti-loosening nut body 9 is connected to the reverse thread of the spline sleeve 3. The anti-loosening nut body 9 is used to fix the spline sleeve 3 and prevent the spline sleeve 3 from loosening.

[0015] In this specific embodiment, to prevent the anti-loosening nut body 9 from loosening, threaded holes 9-1 are evenly provided on the outer side wall of the anti-loosening nut body 9. A set screw 9-2 is fixedly connected in the threaded hole body 9-1. The head of the set screw 9-2 contacts the outer side wall of the spline sleeve 3. The set screw 9-2 is used to achieve secondary fixation of the anti-loosening nut body 9, preventing the anti-loosening nut body 9 from loosening due to bearing damage.

[0016] The working principle of this specific embodiment is as follows: During use, the spline sleeve 3 is rotated by the pulley 5, and the spline shaft 6 can move axially within the spline sleeve 3, enabling the spline shaft 6 to rotate and move axially. The axial movement of the spline shaft 6 within the spline sleeve 3 is relatively smooth. At the same time, lubricating oil is added to the spline shaft 6, and when burrs appear on the spline shaft 6, they can be polished smooth by friction, making it less prone to jamming and extending its service life. The force-bearing area between the spline sleeve 3 and the spline shaft 6 is increased, resulting in high stability and smooth operation. When the spline shaft 6 rotates and moves axially, the spline sleeve 3 uses two bearings 7 to distribute the force, making the force even and preventing damage caused by uneven force on the bearings 7. At the same time, the oil reservoir 1-3 is lubricated through the oil nozzle 8, so that the bearings 7 can be lubricated and extend the service life of the bearings 7. Furthermore, the anti-loosening nut body 9 with set screw 9-2 is used to improve the stability of the fixation, making it less likely for the anti-loosening nut body 9 to loosen.

[0017] Specific Implementation Method Two: Combining Figures 6 to 8 The following describes this specific embodiment. The difference between this specific embodiment and the first specific embodiment is that: several locking pieces 9-3 are welded to the outer wall of the anti-loosening nut body 9, and several concave locking grooves 3-1 are evenly opened on the outer wall of the spline sleeve 3. The locking pieces 9-3 are locked with the locking grooves 3-1. Other combinations and connection relationships are the same as in the first specific embodiment.

[0018] In this specific embodiment, after the anti-loosening nut body 9 is tightened, the locking is achieved by the locking piece 9-3 engaging with the locking groove 3-1. This method is less likely to cause damage to the set screw and reverse the thread. At the same time, when the locking piece 9-3 and the locking groove 3-1 cannot be aligned, the locking piece 9-3 can be rotated in the opposite direction when the anti-loosening nut body 9 reaches the fixed torque, so that the locking piece 9-3 engages with the locking groove 3-1.

[0019] A further embodiment of this specific solution is as follows: the spacing between the plurality of snap-fit ​​grooves 3-1 is 15-30cm, and the width of the snap-fit ​​grooves 3-1 is 5-10cm; the width of the snap-fit ​​piece 9-3 is 4-9cm, and the width of the snap-fit ​​piece 9-3 is less than or equal to the width of the snap-fit ​​groove 3-1. In this specific embodiment, it is generally preferred that the width of the snap-fit ​​piece 9-3 is less than the width of the snap-fit ​​groove 3-1, so that the snap-fit ​​piece 9-3 can quickly snap into the snap-fit ​​groove 3-1, and at the same time, the anti-loosening nut body 9 is not prone to loosening.

[0020] Reference Figure 8 As shown, in this specific embodiment, the plurality of snap-fit ​​pieces 9-1 are preferably six, with the distance between the first snap-fit ​​piece and the second snap-fit ​​piece being 1cm, the distance between the second snap-fit ​​piece and the third snap-fit ​​piece being 2cm, the distance between the third snap-fit ​​piece and the fourth snap-fit ​​piece being 3cm, the distance between the fourth snap-fit ​​piece and the fifth snap-fit ​​piece being 4cm, and the distance between the fifth snap-fit ​​piece and the sixth snap-fit ​​piece being 5cm; or the distance between each snap-fit ​​piece increases by 2cm sequentially, such as the distance between the first snap-fit ​​piece and the second snap-fit ​​piece being 2cm, and the distance between the second snap-fit ​​piece and the third snap-fit ​​piece being 4cm.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
