Description

Technical Field

[0001] The utility model relates to the technical field of transmission auxiliary equipment, in particular to an oil-unloading swing arm capable of reducing transmission power consumption. Background Art

[0002] The transmission system is the core component used to transmit power and motion in mechanical equipment. In a variety of equipment such as automobiles and industrial machinery, these systems transmit power and motion through belts or chains. The efficiency, reliability and life of these systems directly affect the performance of the entire mechanical equipment. Tensioners play a vital role in keeping transmission systems (such as chains and belts) properly tensioned. They ensure that the transmission system maintains stable tension under different operating conditions and prevents slipping, tooth jumping or shedding. This is essential to maintain transmission efficiency and prevent early wear. The swing arm is a key part of the tensioner and is in direct contact with the belt or chain. Its design needs to take into account wear resistance, stability and the ability to effectively transmit tension. The design and material selection of the swing arm are crucial to reducing the overall wear of the system and maintaining stable tension.

[0003] However, the tensioner in the prior art has the following technical problems:

[0004] Long-term operation will cause eccentric wear on the contact surface between the swing arm and the tensioner piston, especially when the contact surface is designed to be a straight surface. Eccentric wear will cause uneven wear of these components, thus affecting the performance of the entire system.

[0005] This causes additional energy loss and reduced transmission efficiency due to friction between the swing arm and the belt or chain. Friction also increases wear on components, resulting in more frequent maintenance and replacement.

[0006] In these systems, proper lubrication is critical to reduce wear and maintain operating efficiency. However, in traditional designs, lubricant is often not evenly distributed, especially in the contact area of ​​the swing arm and chain. This leads to insufficient lubrication, further increasing wear and failure rates.

[0007] Due to the above problems, especially eccentric wear and insufficient lubrication, traditional transmission systems may have stability and reliability problems in long-term operation. These problems may lead to sudden failure of the transmission system, affecting the safety and performance of the entire mechanical equipment.

[0008] To this end, the utility model provides an oil-unloading swing arm that can reduce transmission power consumption to solve the above-mentioned problems of significant efficiency decline, increased wear and maintenance requirements, as well as stability and reliability during long-term use. Utility Model Content

[0009] The purpose of the utility model is to provide an oil-unloading swing arm that can reduce transmission power consumption, and solves the technical problems that the contact surface between the swing arm and the piston is a flat surface, and long-term eccentric wear will form a depression, resulting in a large lateral force, and even tensioning failure in severe cases, and there is also friction between the swing arm and the belt and chain, which will cause wear and high power consumption of the transmission system.

[0010] The above technical objectives of the utility model are achieved through the following technical solutions:

[0011] An oil-unloading swing arm capable of reducing transmission power consumption comprises a rocker arm, wherein the rocker arm is located between a tensioner piston and a chain, the top surface of the tensioner piston is a plane, and a convex surface is formed at a contact position between the plane and the tensioner piston, at least one through hole is connected between the convex surface and a side of the rocker arm away from the tensioner piston, so that the tensioner piston can inject oil through the through hole, side guard edges are fixed on both sides of the convex surface, and the spacing between the two side guard edges is consistent with the diameter of the tensioner piston.

[0012] Beneficial effects: The buffered oil-unloading swing arm has a process in which the contact position between the flat surface and the convex surface is constantly changed during the rotation of the swing arm around a center of a circle, which can prevent eccentric wear and increase the stability of the tensioning system. The side guard can prevent the lateral displacement of the swing arm, making it difficult for the tensioning system to break away and fail. When the tensioning system is running, the tensioner piston movement can spray oil, and the sprayed oil acts on the chain through the through hole, which can reduce the friction between the chain and the swing arm and reduce the transmission power consumption.

[0013] Furthermore, when the rocker arm swings around a center of a circle, the flat surface and the convex surface always maintain a fitting state.

[0014] Furthermore, the rocker arm has an arc-shaped structure so that the chain can slide along the outer diameter of the rocker arm during transmission.

[0015] Furthermore, the through hole is in a strip-shaped structure, and the distance between the end walls on both sides gradually increases from the convex surface to the side of the rocker arm away from the tensioner piston.

[0016] Furthermore, the cross-section of the through hole is arranged in a rectangular or trapezoidal structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] See Figures 1 to 8 As shown, an oil-unloading swing arm capable of reducing transmission power consumption comprises a rocker arm 1, wherein the rocker arm 1 is located between a tensioner piston 2 and a chain, and the rocker arm 1 is in an arc-shaped structure so that the chain can slide along the outer diameter of the rocker arm 1 during transmission;

[0027] Specifically, the arc-shaped structure of the rocker arm matches the natural path of the chain during transmission. This design allows the chain to slide smoothly along the outer diameter of the rocker arm, reducing the additional friction and resistance caused by turning or changing the path.

[0028] In a traditional flat swingarm design, the chain encounters more resistance during turns, especially with large angle changes. The curved swingarm reduces resistance during turns by reducing these angle changes.

[0029] This curved design of the rocker arm provides a smoother sliding surface, which reduces friction when the chain is in motion, because the contact between the chain and the rocker arm is more closely aligned with its natural curvature.

[0030] Due to the reduced steering resistance and friction, the power consumption of the entire drive system is significantly reduced. This means that the system requires less energy, thereby improving energy efficiency.

[0031] Reduced friction and drag not only reduces power consumption, but also reduces wear on the chain and rocker arms. This helps extend the life of the drivetrain and reduces maintenance and replacement costs.

[0032] By reducing friction and resistance in chain movement, the drive train is able to operate more smoothly and efficiently. This improves the overall performance and reliability of mechanical equipment.

[0033] Furthermore, the top surface of the tensioner piston 2 is a plane 3, and a convex surface 4 is formed at the contact position between the plane 3 and the tensioner piston 2. When the rocker arm 1 swings around a center of a circle, the plane 3 and the convex surface 4 always keep in contact.

[0034] Specifically, the cross-section of the convex surface 4 is arc-shaped. When the rocker arm 1 rotates, the convex surface 4 is relatively displaced. The contact position between the plane 3 and the convex surface 4 remains unchanged, while the contact position between the convex surface 4 and the plane 3 changes continuously, which can prevent eccentric wear and increase the stability of the tensioning system.

[0035] The combination of flat and convex surfaces is designed to solve the problem of eccentric wear of the contact surface between the swing arm and the tensioner piston during long-term use. In traditional designs, the contact surface between the swing arm and the piston is usually flat. After long-term operation, this contact surface gradually forms a depression due to uneven friction, resulting in eccentric wear, which in turn affects the stability and efficiency of the entire system.

[0036] In this embodiment, a portion of the swing arm forms a convex surface that contacts the flat surface of the tensioner piston. Due to the curvature of the convex surface, the point of contact between the swing arm and the flat surface changes continuously during movement. This dynamically changing contact pattern means that the friction force is more evenly distributed across the contact surface, significantly reducing excessive wear in any particular area.

[0037] Therefore, through this combination of flat and convex surface design, the phenomenon of eccentric wear and concavity can be effectively reduced, the service life of the swing arm can be extended, and the stability and efficient operation of the transmission system can be ensured. In general, this design improves the durability and stability of the entire transmission system, reduces maintenance requirements, and improves overall efficiency.

[0038] Furthermore, at least one through hole 5 is connected between the convex surface 4 and the side of the rocker arm 1 away from the tensioner piston 2, so that the tensioner piston 2 can inject oil through the through hole 5. The through hole 5 is a strip-shaped structure, and the distance between the end walls on both sides gradually increases from the convex surface 4 to the side of the rocker arm 1 away from the tensioner piston 2.

[0039] Specifically, the main function of the through hole is to allow the tensioner piston to spray oil through and directly lubricate the swing arm and chain. This direct lubrication method effectively reduces the friction between the swing arm and the chain and reduces wear. The strip design of the through hole and the gradual increase in the distance between the end walls on both sides allow the lubricating oil to spread outward along the swing arm, forming a wider lubrication coverage area.

[0040] Through the carefully designed through-holes, the lubricating oil can be more evenly and widely distributed on the contact surface of the swing arm and the chain. This uniform lubrication greatly reduces friction and wear. Effective lubrication reduces energy loss in the transmission system, thereby improving the working efficiency of the entire system. This is very important for reducing energy consumption and improving the overall performance of mechanical equipment. Due to the reduction of friction and wear, this design helps to extend the service life of key components such as the swing arm and chain, reduce the frequency of maintenance and replacement, and thus reduce long-term operating costs. Uniform and effective lubrication not only reduces wear, but also helps to improve the stability of the entire transmission system and reduce the possibility of failure.

[0041] Furthermore, the cross-section of the through hole 5 is arranged in a rectangular or trapezoidal structure.

[0042] Specifically, the inner wall of the through hole 5 is straight, which is conducive to the oil directly passing through or contacting the inner wall of the through hole 5 and then being reflected and sprayed out, ensuring the oiling effect of the chain. The rectangular or trapezoidal through hole design provides a regular and controllable path, allowing the lubricating oil to pass through the swing arm in a more stable and effective manner.

[0043] Specifically, the rectangular through-holes can evenly distribute the lubricating oil. The rectangular through-holes have right-angled edges, which make it easier for the lubricating oil to be evenly distributed on the contact surface. This uniform lubrication helps reduce friction and wear, and improve the efficiency and life of the transmission system. Since the rectangular through-holes have clear boundaries, the flow of lubricating oil can be more easily controlled. This allows the operator to adjust the amount of lubricating oil as needed to meet the needs of different working conditions. The rectangular through-holes usually have a larger area and can provide a more stable lubrication effect. This design is suitable for scenarios that require a large amount of lubricating oil, such as mechanical equipment under high load, high speed or high temperature environments.

[0044] The through-holes set in a trapezoidal shape can be adjusted according to actual needs, and their characteristic is that they can be widened or narrowed. The flexibility of this design means that it can adapt to swing arms and chains of different shapes or sizes. For example, in the lubrication system, the swing arms and chains have different shapes or sizes, and the through-holes with a trapezoidal design can be adjusted according to their characteristics, ensuring that the lubricant can accurately cover the contact surface and achieve the best lubrication effect. The through-holes with a trapezoidal design can be customized according to the movement trajectory of the chain and the shape of the swing arm, thereby achieving a more precise lubrication effect. This means that the lubricant can be evenly distributed in the contact area of ​​the swing arm and the chain, effectively reducing friction and wear. In contrast, traditional circular through-holes cannot adapt to contact surfaces of different shapes, resulting in poor lubrication or waste of lubricant.

[0045] Preferably, the through hole 5 is of a structure that is wide at the top and narrow at the bottom, which can reduce the dead angle of oil injection of the tensioner piston 2.

[0046] Furthermore, side ribs 6 are fixed on both sides of the convex surface 4, and the distance between the two side ribs 6 is consistent with the diameter of the tensioner piston 2;

[0047] Specifically, the side guard 6 can prevent the rocker arm 1 from shifting sideways, making it difficult for the tensioning system to fail;

[0048] The main function of the side guard is to limit the lateral displacement of the rocker arm. During the operation of the transmission system, the rocker arm may move sideways due to uneven forces or vibrations. The side guard physically limits this movement and ensures that the rocker arm and the tensioner piston remain correctly aligned. The spacing between the side guards is consistent with the diameter of the tensioner piston. This precise match ensures that when the rocker arm rotates around the tensioner piston, the side guard can effectively prevent any unnecessary lateral movement of the rocker arm.

[0049] By preventing the lateral displacement of the rocker arm, the side flange enhances the stability of the entire transmission system. This stability is essential to maintaining transmission efficiency and reducing wear. Under high load or vibration conditions, the rocker arm without the side flange may shift, causing the tensioner to fail. The design of the side flange effectively prevents this situation and ensures the continuous and stable operation of the transmission system. By reducing the additional wear caused by lateral displacement, the presence of the side flange prolongs the service life of the rocker arm and tensioner piston and reduces long-term maintenance costs. In automated or high-speed mechanical systems, the stability of the transmission system is essential to operational safety. The design of the side flange provides additional protection to prevent accidents caused by rocker arm displacement.

[0050] The beneficial effect of this embodiment is that when the rocker arm rotates around the center of the circle, the contact position between the flat surface and the convex surface continues to change. This dynamic contact method effectively prevents the problem of eccentric wear. In the traditional design, the contact surface between the rocker arm and the piston is in a fixed position for a long time, which is prone to local wear over time, thereby affecting the stability and life of the entire system. This new design evenly disperses the pressure and wear by continuously changing the contact point, greatly increasing the stability and durability of the system.

[0051] On the other hand, the design of the side ribs also plays a vital role. They effectively prevent the lateral displacement of the rocker arm, which is a common problem in traditional systems, especially in high-load or high-vibration working environments. By limiting the unintended movement of the rocker arm, these side ribs ensure the stability of the tensioner and prevent the risk of system failure.

[0052] In addition, the tensioner piston in this design has an oil injection function, which is achieved through the through hole on the rocker arm. When the piston moves, it can directly spray oil to the contact area between the rocker arm and the chain, effectively reducing the friction between the two parts. This direct and uniform lubrication method not only reduces the friction between the chain and the rocker arm, but also significantly reduces the power consumption of the entire transmission system. Reduced friction means reduced energy loss and improved efficiency of the entire system.

[0053] In summary, this buffer oil unloading swing arm design not only improves the stability and efficiency of the entire transmission system, but also extends the service life of the equipment. It effectively solves multiple problems in traditional designs, such as eccentric wear, excessive friction and lateral displacement, thereby optimizing the performance of the entire transmission system.
