Description

Technical Field

[0001] This utility model relates to the technical field of gear lubrication and filtration equipment, specifically to a special tool for removing gearbox filter elements. Background Technology

[0002] During gearbox operation, the lubricating oil is constantly contaminated with metal particles, dust, moisture, and other impurities. If these impurities are not removed promptly, they will severely affect the lubricating oil's performance and reduce its cleanliness. A filtration system can effectively remove these contaminants, maintaining oil cleanliness and preventing damage to internal gearbox components. Clean lubricating oil can better perform its lubrication function, reducing wear on internal gearbox components and thus lowering equipment failure rates. Simultaneously, the filtration system can also remove aging products and additive decomposition products from the lubricating oil, maintaining its optimal performance. Therefore, a filtration system can extend the service life of the lubricating oil, reduce replacement frequency, and lower maintenance costs.

[0003] Current gearbox lubricating oil filtration systems circulate the lubricating oil in the gearbox through a filter element for filtration and purification. The filter element will become clogged after a long period of filtration and needs to be replaced regularly. The filter element is located inside the filter cartridge, and due to its tight fit, it is difficult to remove by hand. Therefore, we propose a special tool for removing gearbox filter elements. Utility Model Content

[0004] In view of the above-mentioned technical problems in related technologies, this utility model provides a special tool for removing gearbox filter elements, which can solve the above problems.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:

[0006] A special tool for removing gearbox filter elements includes an outer cylinder and a long rod fitted inside the outer cylinder. Several grooves are vertically and equidistantly opened on both sides of the outer cylinder's circumference. Each groove is hinged with a stop block by a pin. When the long rod is inserted into the outer cylinder, the stop block rotates towards the outside of the groove.

[0007] Furthermore, the side of the abutment block facing the inside of the outer cylinder is integrally formed with a sloping surface.

[0008] Furthermore, handles A are fixedly installed on both sides of the outer circumference of the top of the outer cylinder.

[0009] Furthermore, handles B are fixedly installed on both sides of the top circumference of the long rod.

[0010] Furthermore, the diameter of the long rod is 2mm smaller than the inner diameter of the outer cylinder.

[0011] Furthermore, the length of the long rod is 5cm longer than the inner cavity length of the outer cylinder.

[0012] The beneficial effects of this utility model are as follows: The outer cylinder of the device is inserted into the channel hole in the middle of the gearbox filter element, and then the long rod is inserted into the inner cavity of the outer cylinder. During the process, the long rod will push the abutment block to rotate outward, so that the abutment block is pressed against the inner wall of the channel hole. Subsequently, the gearbox filter element can be taken out by lifting the outer cylinder. The gearbox filter element can be taken out easily and quickly. After removing the long rod, the outer cylinder and the gearbox filter element can be easily separated. The operation is simple and quick. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0022] like Figure 1-4As shown, this utility model discloses a special tool for removing gearbox filter elements, including an outer cylinder 1 and a long rod 4 sleeved inside the outer cylinder 1. Several grooves 101 are vertically and equidistantly opened on both sides of the circumferential surface of the outer cylinder 1. Each groove 101 is hinged with a stop block 2 by a pin. When the long rod 4 is inserted into the outer cylinder 1, the stop block 2 rotates towards the outside of the groove 101.

[0023] Example 1: The outer cylinder 1, the stop block 2, and the long rod 4 are made of polyamide (PA), which is high-strength, high-toughness, wear-resistant, and fatigue-resistant, capable of withstanding large tensile, compressive, and bending stresses. Several grooves 101 are vertically and equidistantly formed on both sides of the outer cylinder 1's circumference. A pin is inserted through each groove 101, and the pin engages with the stop block 2, allowing the stop block 2 to rotate within the groove 101. Clamps are fitted at both ends of the pin to limit its movement and prevent it from falling off. The stop block 2 is located close to the inside of the outer cylinder 1. One end of the cavity is provided with a ramp surface 201, which can be linked with the long rod 4. Two abutments 2 at the same horizontal position are symmetrically arranged about the vertical center line of the outer cylinder 1. The outer diameter of the outer cylinder 1 is 10mm smaller than the channel hole 601. When the outer cylinder 1 is fully inserted into the channel hole 601, the long rod 4 is then inserted into the outer cylinder 1. The long rod 4 pushes the abutments 2 to rotate outward adaptively, so that the abutments 2 are pressed against the inner wall of the channel hole 601. By pulling out the outer cylinder 1, the gearbox filter element 6 can be taken out of the filter cylinder.

[0024] In the preferred technical solution, the side of the abutment block 2 facing the inside of the outer cylinder 1 is integrally formed with a ramp surface 201. The ramp surface 201 is set to facilitate linkage with the long rod 4. The abutment block 2 can be pushed to rotate by the long rod 4 and the ramp surface 201.

[0025] In the preferred technical solution, handles A3 are fixedly provided on both sides of the outer circumference of the top of the outer cylinder 1. The handles A3 are made of the same material as the outer cylinder 1, and the handles A3 facilitate the pulling of the outer cylinder 1.

[0026] In the preferred technical solution, handles B5 are fixedly installed on both sides of the top circumference of the long rod 4. The handles B5 are made of the same material as the long rod 4, and the handles B5 facilitate the removal of the long rod 4.

[0027] In the preferred technical solution, the diameter of the long rod 4 is 2mm smaller than the inner diameter of the outer cylinder 1, which facilitates the insertion of the long rod 4 into the inner cavity of the outer cylinder 1.

[0028] In the preferred technical solution, the length of the long rod 4 is 5cm longer than the inner cavity length of the outer cylinder 1, so that after the long rod 4 is inserted into the outer cylinder 1, the top end still has 5cm protruding outside, thus making it easy to remove the long rod 4.

[0029] In practical use, the outer cylinder 1 is fully inserted into the channel hole 601, and the long rod 4 is then inserted into the outer cylinder 1. The long rod 4 contacts the top of the inclined surface 201 of the abutment 2, so that the long rod 4 pushes the abutment 2 to rotate outward adaptively, so that the abutment 2 is pressed against the inner wall of the channel hole 601. Pulling out the outer cylinder 1 can remove the gearbox filter element 6 from the filter cylinder. Then, the long rod 4 and the outer cylinder 1 are pulled out in sequence to remove the gearbox filter element 6.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
