Description

Technical Field

[0001] This utility model relates to the field of tensioning components, and more particularly to a tensioning assembly mechanism for an air assembly. Background Technology

[0002] In today's industrial sector, air assemblies are widely used in various equipment, such as ventilation systems, air handling equipment, and pneumatic machinery. Their performance directly affects the operating efficiency, stability, and service life of the related equipment. During the operation of air assemblies, the tensioning assembly mechanism, as a key component, plays a crucial role in ensuring the normal operation of the transmission components within the air assembly.

[0003] Existing air component tensioning and assembly mechanisms generally suffer from unreasonable structural design. Some tensioning mechanisms employ simple fixed tensioning methods, failing to automatically adjust the tension force according to changes in the air component under different operating conditions. For example, after prolonged operation, the drive chain or belt may stretch due to wear. Fixed tensioning mechanisms cannot compensate for this stretching in time, leading to chain or belt slack and slippage. This not only reduces transmission efficiency but also accelerates chain or belt wear, increasing equipment maintenance costs and downtime. Based on this, we propose a new air component tensioning and assembly mechanism. Utility Model Content

[0004] To solve the technical problems of tensioning components, this utility model provides a tensioning assembly mechanism for air components.

[0005] This utility model is achieved by the following technical solution: a tensioning assembly mechanism for an air component, including a chain belt, a first chain pulley, a second chain pulley, and a fixed base, wherein the two ends of the chain belt are sleeved on the surfaces of the first chain pulley and the second chain pulley;

[0006] The top of the fixed base is provided with a connecting shaft, and the upper deflection shaft and the lower deflection shaft are rotatably connected to the connecting shaft. The connecting shaft hinges the upper deflection shaft and the lower deflection shaft to the fixed base, and the upper deflection shaft and the lower deflection shaft deflect around the connecting shaft.

[0007] The lower deflection shaft is connected to a lower motion shaft at its top end. One end of the lower motion rod is connected to the lower motion shaft, and the other end of the lower motion rod is connected to a lower tension gear. The top end of the mounting support is fitted onto the surface of the lower motion rod. The upper deflection shaft is connected to an upper motion shaft at its top end. One end of the upper motion rod is connected to the upper motion shaft, and the other end of the upper motion rod is connected to an upper tension gear. The top end of the receiving frame is fitted onto the surface of the upper motion rod, and the threaded part of the nut lock penetrates the surface of the receiving frame. A connecting column connects the mounting support and the receiving frame.

[0008] When the chain belt becomes loose during use, tension can be restored by adjusting the locking part of the nut. The thread of the locking part of the nut passes through the support frame, which is sleeved on the top of the upper moving rod. The mounting column is sleeved on the top of the lower moving rod, and the mounting column and the support frame are connected by a connecting column.

[0009] When the rotating nut locks in place, its threaded engagement with the support frame causes the support frame to move along the upper moving rod. This movement of the support frame, via the connecting column, moves the mounting column, which in turn causes the lower and upper moving rods to rotate around their respective axes. This movement moves the lower and upper tensioning gears closer to or further away from the chain belt. The upper tensioning gear engages with the upper surface of the upper chain belt, and the lower tensioning gear engages with the lower surface of the lower chain belt. Their movement applies tension to the chain belt, compensating for elongation caused by wear and other factors, ensuring the chain belt maintains appropriate tension at all times.

[0010] As a further improvement to the above scheme, both the upper tensioning gear and the lower tensioning gear are provided with raised triangular teeth on their surfaces.

[0011] As a further improvement to the above scheme, the upper tensioning gear is attached to the upper surface of the upper chain belt, and the lower tensioning gear is attached to the lower surface of the lower chain belt.

[0012] As a further improvement to the above scheme, the top of the lower deflection shaft is connected to the lower motion axis, one end of the lower motion rod is connected to the lower motion axis, and the other end is connected to the lower tension gear; similarly, the top of the upper deflection shaft is connected to the upper motion axis, one end of the upper motion rod is connected to the upper motion axis, and the other end is connected to the upper tension gear. This structural design allows the upper and lower tension gears to adjust their positions as the deflection shaft rotates.

[0013] As a further improvement to the above solution, the chain is made of rubber with embedded metal reinforcing wires to improve its wear resistance and tensile strength.

[0014] As a further improvement to the above scheme, the two ends of the chain belt are fitted onto the surfaces of the first and second chain pulleys, which constitute the basic structure of the transmission. The first and second chain pulleys are mounted on a fixed base. During equipment operation, one of the chain pulleys, such as the first chain pulley, is usually driven to rotate by the drive device, which in turn drives the second chain pulley to rotate through the chain belt, thereby realizing the transmission of power and providing power support for the operation of the air assembly.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through its unique structural design, allows for convenient adjustment of the chain when it becomes slack, via a rotating nut locking mechanism. The nut locking mechanism moves the receiving frame, which in turn rotates the upper and lower moving rods, causing the upper and lower tensioning gears to move closer to or further away from the chain. This precisely compensates for chain elongation, ensuring the chain maintains appropriate tension at all times. This effectively prevents chain slippage, improves transmission stability, ensures stable operation of the air assembly under various working conditions, and reduces equipment failures caused by chain problems.

[0017] 2. This utility model features raised triangular teeth on the surfaces of the upper and lower tension gears, which respectively overlap the upper and lower surfaces of the chain belt. These teeth increase the friction and engagement force with the chain belt, making the transmission between the chain belt and the tension gears more reliable and reducing the likelihood of relative slippage. During power transmission, power can be transferred more efficiently from the pulley to the chain belt, reducing energy loss, improving the overall transmission efficiency of the air assembly, and lowering the equipment's operating energy consumption.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] Example 1:

[0024] Please combine Figures 1-2 This embodiment proposes a tensioning assembly mechanism for an air assembly, including a chain belt 1, a first chain pulley 2, a second chain pulley 3, and a fixing seat 4. The two ends of the chain belt 1 are sleeved on the surfaces of the first chain pulley 2 and the second chain pulley 3. The chain belt 1 is made of rubber material and has metal reinforcing wires embedded inside to improve the wear resistance and tensile strength of the chain belt.

[0025] In the specific technical solution, during installation, both ends of the chain belt 1 are fitted onto the surfaces of the first chain pulley 2 and the second chain pulley 3, which constitutes the basic structure of the transmission. The first chain pulley 2 and the second chain pulley 3 are mounted on the fixed base 4. During equipment operation, one of the chain pulleys, such as the first chain pulley 2, is usually driven to rotate by the drive device, which in turn drives the second chain pulley 3 to rotate through the chain belt 1, realizing the transmission of power and providing power support for the operation of the air assembly.

[0026] The top of the fixed base 4 is provided with a connecting shaft 5, and the upper deflection shaft 6 and the lower deflection shaft 7 are rotatably connected to the connecting shaft 5 respectively; the connecting shaft 5 hinges the upper deflection shaft 6 and the lower deflection shaft 7 to the fixed base 4, and the upper deflection shaft 6 and the lower deflection shaft 7 deflect around the connecting shaft 5.

[0027] The lower deflection shaft 7 is connected to the top end of the lower motion shaft 71, one end of the lower motion rod 72 is connected to the lower motion shaft 71, and the other end of the lower motion rod 72 is connected to the lower tension gear 73; the top end of the mounting support 74 is sleeved on the surface of the lower motion rod 72.

[0028] The top end of the upper deflection shaft 6 is connected to the upper motion shaft 8. One end of the upper motion rod 81 is connected to the upper motion shaft 8, and the other end of the upper motion rod 81 is connected to the upper tension gear 82. Both the upper tension gear 82 and the lower tension gear 73 have raised triangular teeth on their surfaces. The upper tension gear 82 rests on the upper surface of the upper chain belt 1, and the lower tension gear 73 rests on the lower surface of the lower chain belt 1.

[0029] Specifically, in this technical solution, the connecting shaft 5 at the top of the fixed base 4 is hinged to the upper deflection shaft 6 and the lower deflection shaft 7, allowing them to deflect around the connecting shaft 5. The top of the lower deflection shaft 7 is connected to the lower motion shaft 71, and one end of the lower motion rod 72 is connected to the lower motion shaft 71, while the other end is connected to the lower tension gear 73. Similarly, the top of the upper deflection shaft 6 is connected to the upper motion shaft 8, and one end of the upper motion rod 81 is connected to the upper motion shaft 8, while the other end is connected to the upper tension gear 82. This structural design allows the upper and lower tension gears to adjust their positions as the deflection shafts rotate.

[0030] The top of the support frame 83 is fitted onto the surface of the upper moving rod 81, and the nut locking part 84 is threaded through the surface of the support frame 83; a connecting column 9 is connected between the mounting column 74 and the support frame 83.

[0031] A more specific technical solution is that when the chain belt 1 becomes loose during use, tension can be achieved by adjusting the nut locking part 84. The nut locking part 84 is threaded through the support frame 83, which is sleeved on the top of the upper moving rod 81. The mounting column 74 is sleeved on the top of the lower moving rod 72, and the mounting column 74 and the support frame 83 are connected by a connecting column 9.

[0032] When the rotating nut locking part 84 is engaged with the threaded part of the receiving frame 83, the receiving frame 83 will move along the upper moving rod 81. The movement of the receiving frame 83 drives the mounting support 74 to move through the connecting column 9, which in turn causes the lower moving rod 72 and the upper moving rod 81 to rotate around the lower moving axis 71 and the upper moving axis 8, respectively, causing the lower tension gear 73 and the upper tension gear 82 to move closer to or away from the chain belt 1. The upper tension gear 82 is engaged with the upper surface of the upper chain belt 1, and the lower tension gear 73 is engaged with the lower surface of the lower chain belt 1. Through their movement, tension is applied to the chain belt 1 to compensate for the elongation of the chain belt due to wear and other reasons, ensuring that the chain belt always maintains a suitable tension.

[0033] The working principle of the tensioning assembly mechanism of this air assembly is as follows:

[0034] Initial Installation and Transmission Foundation: During installation, the two ends of the chain belt 1 are fitted onto the surfaces of the first chain pulley 2 and the second chain pulley 3, forming the basic transmission structure. The first chain pulley 2 and the second chain pulley 3 are mounted on the fixed base 4. During equipment operation, one of the chain pulleys, such as the first chain pulley 2, is usually driven to rotate by the drive device, which in turn drives the second chain pulley 3 to rotate through the chain belt 1, realizing the transmission of power and providing power support for the operation of the air assembly.

[0035] Tension adjustment mechanism: The connecting shaft 5 at the top of the fixed base 4 is hinged to the upper deflection shaft 6 and the lower deflection shaft 7, allowing them to deflect around the connecting shaft 5. The top of the lower deflection shaft 7 is connected to the lower motion shaft 71, and one end of the lower motion rod 72 is connected to the lower motion shaft 71, while the other end is connected to the lower tension gear 73. Similarly, the top of the upper deflection shaft 6 is connected to the upper motion shaft 8, and one end of the upper motion rod 81 is connected to the upper motion shaft 8, while the other end is connected to the upper tension gear 82. This structural design allows the upper and lower tension gears to adjust their positions as the deflection shafts rotate.

[0036] Tension Adjustment Mechanism - Tensioning Process: When the chain belt 1 becomes slack during use, tension can be achieved by adjusting the nut locking part 84. The nut locking part 84 is threaded through the support frame 83, which is sleeved on the top of the upper moving rod 81. The mounting support 74 is sleeved on the top of the lower moving rod 72, and the mounting support 74 is connected to the support frame 83 by a connecting post 9. When the nut locking part 84 is rotated, due to its threaded engagement with the support frame 83, the support frame 83 will move along the upper moving rod 81. The movement of the support frame 83 drives the mounting support 74 to move through the connecting post 9, thereby causing the lower moving rod 72 and the upper moving rod 81 to rotate around the lower moving axis 71 and the upper moving axis 8, respectively, driving the lower tension gear 73 and the upper tension gear 82 to move closer to or away from the chain belt 1. The upper tensioning gear 82 is engaged with the upper surface of the upper chain belt 1, and the lower tensioning gear 73 is engaged with the lower surface of the lower chain belt 1. Through their movement, tension is applied to the chain belt 1 to compensate for the elongation of the chain belt due to wear and other reasons, and to ensure that the chain belt always maintains a suitable tension.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
