Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tooling, in particular to an oiling tooling. Background Art

[0002] Bearings are installed at both ends of the roller and are key components for smooth roller operation. However, during actual use, if impurities enter the bearings, they will cause wear and damage, significantly affecting the normal operation and service life of the roller. To effectively prevent impurities from entering the bearings, it is necessary to install a cover on the outside of the bearing. This can block external impurities such as dust and particles, providing a relatively clean working environment for the bearings.

[0003] To ensure the bearings remain well lubricated during operation, lubricating oil can be filled into the grooves of the cover. Once the cover is installed, as the roller rotates, the lubricating oil in the grooves gradually reaches the bearings, providing continuous lubrication. This design effectively reduces bearing friction loss and improves their operating efficiency and lifespan.

[0004] However, filling the cap with lubricant currently relies primarily on manual labor. This method has several significant drawbacks. First, manual filling is inefficient and requires significant time and labor. Second, manual filling often results in uneven distribution of lubricant, potentially resulting in excessive lubrication in some areas and insufficient lubrication in others. This prevents adequate lubrication of all bearing components, impacting overall bearing performance. Utility Model Content

[0041] Reference Figures 1 to 8 , which is the first embodiment of the utility model, proposes a roller, including a roller body 1; a rotating shaft 2 is arranged in the roller body 1 and coincides with the axis of the roller body 1; there are two bearings 3, which are sleeved outside the rotating shaft 2 and located at both ends of the roller body 1.

[0042] In this embodiment, the roller body 1 is mated with a rotating shaft 2, which is located inside the roller body 1 and aligns with its axis. Bearings 3 are installed at both ends of the roller body 1, ensuring a tight fit between the bearings 3 and the rotating shaft 2. When assembling the roller, first insert the rotating shaft 2 into the roller body 1, aligning its axis with the axis of the roller body 1. Then, install the bearings 3 at both ends of the roller body 1, using specialized installation tools to ensure a secure fit.

[0043] The advantages are simple structure, ease of manufacture and installation. The combination of roller body 1, shaft 2, and bearing 3 effectively transmits power, enabling the roller to operate stably while conveying materials. This ensures stable and reliable operation of the roller, extends its service life, and reduces maintenance costs.

[0044] A sealing cover for a roller includes two sealing plates 4, which are respectively arranged at both ends of the roller body 1 and arranged opposite to each other. The sealing plate 4 has a first groove 401 and a second groove 402. The first groove 401 and the second groove 402 form a protective space with one side of the bearing 3.

[0045] In this embodiment, the cover includes two sealing plates 4, one at each end of the roller body 1 and positioned opposite each other. The sealing plates 4 are bolted to the roller body 1 to ensure a secure fit. When installing, the sealing plates 4 are placed at each end of the roller body 1, ensuring close contact with the bearing 3.

[0047] A lubricating tool is used for a sealing cover. The sealing plate 4 also has a first positioning portion 403, including a mounting seat 5, and the mounting seat 5 has a first oil filling hole 501; one end of the oil filling sleeve 6 is set on the mounting seat 5, coinciding with the axis of the mounting seat 5, and an oil filling space is formed between the oil filling sleeve 6 and the mounting seat 5. The oil filling sleeve 6 has several second oil filling holes 601 and third oil filling holes 602. The other end of the oil filling sleeve 6 also has a positioning groove 603. After the first positioning portion 403 abuts the positioning groove 603, the several second oil filling holes 601 are aligned with the first groove 401, and the several third oil filling holes 602 are aligned with the second groove 402.

[0048] In this embodiment, the mounting base 5 has a first oiling hole 501. One end of the oiling sleeve 6 is positioned on the mounting base 5 and coincides with the axis of the mounting base 5, forming an oiling space between the two. The oiling sleeve 6 has a plurality of second oiling holes 601 and third oiling holes 602, and a positioning groove 603 at the other end. The first positioning portion 403 of the sealing plate 4 is brought into contact with the positioning groove 603 of the oiling sleeve 6, so that the second oiling holes 601 are aligned with the first groove 401, and the third oiling holes 602 are aligned with the second groove 402. Lubricating oil is injected through the first oiling hole 501, and the lubricating oil flows through the oiling holes of the oiling sleeve 6 into the groove of the sealing plate 4.

[0049] The advantage lies in providing a tool specifically designed for filling lubricating oil into the cap, ensuring that the lubricating oil is evenly filled into the groove of the sealing plate 4, providing good lubrication for the bearing 3. This avoids the problem of uneven manual filling, improving the lubrication effect and the service life of the bearing 3. This improves the efficiency and accuracy of lubricating oil filling, reduces the uncertainty of manual operation, and ensures the lubrication effect and service life of the roller. It also facilitates operation and maintenance, reducing operating costs.

[0050] Furthermore, one end of the mounting seat 5 has a plurality of first plug-in portions 502, and the oil filling sleeve 6 has a plurality of first slots 604. The first slots 604 have an insertion section 6041 and a clamping section 6042.

[0054] In this embodiment, the first sliding rod 7 has a first step 701 at one end, which is vertically slidably mounted on the top wall of the first slot 604. After the oiling sleeve 6 is connected to the mounting base 5, the first sliding rod 7 slides under the action of gravity, so that its other end is located in the first slot 604 and abuts against the first plug portion 502, preventing the oiling sleeve 6 from rotating.

[0055] The advantages are that the oil filling sleeve 6 is prevented from rotating during the oil filling process, the alignment accuracy of the oil filling hole is guaranteed, and the accuracy and stability of the oil filling are improved. The operation is simple and convenient, and the use efficiency of the oiling tool is improved.

[0056] Furthermore, it also includes a second sliding rod 8, which is vertically slidably set in the mounting seat 5. After the second sliding rod 8 slides, one end extends out of the mounting seat 5 and abuts against one end of the first sliding rod 7 located in the insertion section 6041, pushing the first sliding rod 7 to slide out of the insertion section 6041.

[0057] In this embodiment, the second sliding rod 8 is vertically slidably disposed within the mounting seat 5. To remove the oiling sleeve 6, the second sliding rod 8 is slid so that one end thereof extends out of the mounting seat 5 and abuts against the end of the first sliding rod 7 located in the insertion section 6041, thereby pushing the first sliding rod 7 out of the insertion section 6041 and releasing the rotation restriction between the oiling sleeve 6 and the mounting seat 5.

[0058] The advantage is that a convenient method is provided for disassembling the oiling sleeve 6, and the oiling tool is convenient for maintenance and servicing. The operation is simple and easy, and the oiling sleeve 6 can be quickly disassembled, thereby improving work efficiency.

[0059] Furthermore, the second sliding rod 8 has a first abutting surface 801 at one end away from the oil injection sleeve 6, and the first abutting surface 801 forms a first angle with the horizontal plane, the first angle being α, and further comprising:

[0060] The third sliding rod 9 is slidably arranged in the mounting seat 5. The third sliding rod 9 has a second abutting surface 901. The second abutting surface 901 abuts against the first abutting surface 801. After the third sliding rod 9 slides, the other end of the second sliding rod 8 extends out of or retracts the mounting seat 5.

[0061] In this embodiment, the second sliding rod 8 has a first abutment surface 801 at the end facing away from the oil injection sleeve 6, which forms a first angle α with the horizontal plane. A third sliding rod 9 is slidably disposed within the mounting base 5, with a second abutment surface 901 abutting against the first abutment surface 801 of the second sliding rod 8.

Manual or mechanical operation is simple and convenient, improving efficiency. The guide mechanism enhances the motion precision and stability of the third sliding rod 9, ensuring accurate control of the sliding of the second sliding rod 8 for connection and removal.

[0063] Furthermore, the plurality of second oil injection holes 601 and the third oil injection holes 602 are evenly distributed along the circumference of the axis of the oil injection sleeve 6 .

[0064] In this embodiment, the plurality of second and third oil holes 601, 602 on the oiling sleeve 6 are evenly distributed along the circumference of the axis of the oiling sleeve 6. This ensures that the lubricating oil is evenly injected into the groove of the sealing plate 4, providing comprehensive lubrication for the bearing 3. The number and diameter of the oiling holes are carefully designed to meet the lubrication requirements of sealing plates 4 and bearings 3 of different specifications. During the oiling process, the lubricating oil enters the oiling sleeve 6 through the first oiling hole 501 of the mounting base 5 and flows evenly into the groove of the sealing plate 4 through the evenly distributed oiling holes. A diverter plate can be installed within the oiling sleeve 6 to improve oiling uniformity.

[0065] The advantage is that the lubricating oil is evenly distributed, the lubrication effect of the bearing 3 is improved, and the wear and damage of the bearing 3 are reduced. The design of the oil filling holes evenly distributed around the circumference makes the oil filling process more stable and reliable, ensuring that each part of the bearing 3 can be fully lubricated.
