Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of belt connection devices, and in particular to a quick-release flexible joint for a transmission belt. Background Art
[0002] A transmission belt is a commonly used transmission component in industrial production and is widely used in various mechanical equipment. In practical applications, the connection method of the transmission belt has an important impact on the operating efficiency and maintenance cost of the equipment.
[0003] In traditional transmission systems, especially in equipment where a round belt rotates in an "8" shape with the two ends of the round belt pulleys in a vertical state, when the transmission belt breaks and needs to be replaced, it is usually necessary to stop the machine and disassemble the support structure of the equipment. This not only involves cumbersome operations but also causes the entire production line to shut down, resulting in significant economic losses. To solve this problem, some technical solutions have been proposed in the industry.
[0004] Currently, there are mainly two temporary solutions for dealing with a broken transmission belt: one is to pre-install a spare transmission belt, but this method has the problem of a limited number of spare belts. Once they are used up, it is still necessary to stop the machine and disassemble the shaft; the other is to use the method of hot melting and splicing the broken transmission belt. However, this method not only takes a long time and involves cumbersome operations, but also the strength of the joint after melting is insufficient and it is easy to break again, affecting the normal operation of the equipment.
[0005] The above-mentioned existing technical solutions have the following defects: Although pre-installing a spare round belt and hot melting and splicing a broken round belt solve the problem of replacing the transmission belt without stopping the machine and disassembling the shaft to a certain extent, there are still defects such as cumbersome operation processes, long time consumption, and poor belt strength, and they cannot meet the requirements for rapid replacement of transmission belts in industrial production. Summary of the Invention
[0006] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a quick-release flexible joint for a transmission belt, which has the advantages of quick disassembly and assembly, dynamic multi-directional adaptive adjustment, and high reliability, solves the pain points such as cumbersome disassembly and assembly of traditional joints and easy loosening, wear, etc., effectively ensures the stable operation of the equipment, reduces the production stoppage time caused by belt replacement, and greatly improves production efficiency.
[0007] The above invention purpose of the present invention is achieved through the following technical solutions:
[0008] A quick-release flexible joint for a transmission belt includes a convex flexible joint component and a concave flexible joint component. One end of the convex flexible joint component and one end of the concave flexible joint component are detachably connected in a ball hinge manner, and the other end of the convex flexible joint component and the other end of the concave flexible joint component are respectively fixedly connected to the transmission belt.
[0009] The detachable ball-joint connection allows the flexible joint to rotate flexibly in the connected state, solving the problems of fixed angles and time-consuming assembly and disassembly of traditional rigid joints.
[0010] Furthermore, the convex flexible joint assembly includes an integrally formed convex flexible joint, a prismatic connecting platform and a first threaded rod, the convex flexible joint has a spherical structure; one end of the prismatic connecting platform is connected to the convex flexible joint, and the other end is connected to the first threaded rod; the prismatic connecting platform is fixedly connected to the conveyor belt, and the first threaded rod is inserted in the transmission belt.
[0011] The overall strength and stability of the male flexible joint assembly are ensured by the one-piece structure; the spherical male flexible joint facilitates the flexibility of the ball joint connection; the design of the prismatic connecting platform increases the contact area with the transmission belt, making the fixation more reliable, and the prismatic shape is convenient for positioning during installation; the first threaded rod is inserted into the transmission belt to further strengthen the firmness of the connection and prevent the male flexible joint assembly from detaching from the transmission belt.
[0012] Furthermore, the concave flexible joint assembly includes an integrally formed concave connecting seat and a second threaded rod; the concave connecting seat is prismatic; a accommodating cavity is provided inside it, and the accommodating cavity is connected to the convex flexible joint ball joint; the concave connecting seat is fixedly connected to the conveyor belt, and the second threaded rod is inserted in the transmission belt.
[0013] The strength of the concave flexible joint assembly is ensured by an integrated design; the prismatic concave connecting seat is convenient for installation and positioning and can increase the stability of the connection with the transmission belt; the accommodating cavity can adopt a spherical accommodating cavity, and the spherical structure accommodating cavity is adapted to the spherical structure of the convex flexible joint to achieve a flexible ball joint connection; the second threaded rod is inserted into the transmission belt to tightly connect the concave flexible joint assembly to the transmission belt to prevent it from falling off during the transmission process.
[0014] Furthermore, the accommodating cavity is provided with a top opening and a side opening, the top of the side opening is provided with a notch, the notch is connected to the top opening, the width of the top opening is smaller than the ball head diameter of the convex flexible joint, the width of the side opening is larger than the ball head diameter of the convex flexible joint, and the height of the accommodating cavity is larger than the ball head diameter of the convex flexible joint.
[0015] This technical solution forms a mechanical limit through the coordinated design of multiple openings in the accommodating cavity to prevent the ball head from axially dislodging. Through the side opening and notch guiding design, it achieves rapid guided assembly and allows the ball head to retain dynamic freedom.
[0016] Furthermore, the neck of the convex flexible joint is provided with a cylinder, and the outer surface of the cylinder is provided with two symmetrical rectangular grooves in a direction perpendicular to the axial direction, and the distance between the two rectangular grooves is adapted to the width of the notch; the lateral width of the cylinder is greater than the radial dimension of the top surface opening.
[0017] Through the width adaptation of the rectangular groove and the notch, assembly guidance and initial positioning are achieved. The dimensional difference between the groove wall and the top opening after rotation realizes two-way anti-disengagement limit. At the same time, the symmetric double-groove design of the rectangular groove realizes the universality of assembly at any angle.
[0018] Furthermore, an arc inclined surface that rotates in cooperation with the surface of the rectangular groove is provided at the top edge of the top opening of the accommodation cavity.
[0019] The arc inclined surface serves as a guiding structure to smoothly guide the ball head of the convex connector into the accommodation cavity, avoiding jamming or difficult alignment caused by right-angle edges. At the same time, the arc inclined surface forms a curved surface contact with the surface of the cylinder (including the rectangular groove), allowing the convex connector to rotate at multiple angles within the accommodation cavity, thus adapting to the steering requirements of the transmission belt in complex paths.
[0020] Furthermore, at least two symmetric sides of the prismatic connecting platform and the concave connecting seat are planes.
[0021] Through the design of the prismatic symmetric plane, it is convenient to perform positioning and fixing operations during installation.
[0022] Furthermore, the edges of the upper and lower surfaces of the prismatic connecting platform and the concave connecting seat are in an arc transition shape.
[0023] Through the design of the arc-shaped edges of the prismatic connecting platform, stress concentration is alleviated and the structural strength is enhanced. The arc-shaped edges are in smooth contact with the transmission belt, eliminating sharp edges that do not cut hands, avoiding assembly damage, and being safer and easier to install.
[0024] Furthermore, the radial dimension of the prismatic connecting platform is larger than the outer diameter of the first threaded rod; the radial dimension of the concave connecting seat is larger than the outer diameter of the second threaded rod.
[0025] By optimizing the radial dimension difference of the connecting seat (larger than the outer diameter of the threaded rod), based on the interference fit effect between the threaded rod and the transmission belt, the deformation of the transmission belt can be further restricted, significantly enhancing the anti-pull-off ability, anti-rotation ability, and fatigue resistance of the quick-release connector.
[0026] Furthermore, the outer diameters of both the first threaded rod and the second threaded rod are larger than the hole diameter of the transmission belt, and they are connected by interference fit.
[0027] Through the design that the outer diameter of the threaded rod is larger than the hole diameter of the transmission belt, interference fit connection is achieved, eliminating the need for additional fastening devices and simplifying the connection structure. At the same time, the frictional force generated by the interference fit can effectively prevent relative displacement between the threaded rod and the transmission belt, ensuring the reliability of the connection between the connector and the transmission belt and enabling stable power transmission during the transmission process.
[0028] Further, the first threaded rod and the second threaded rod have the same structure; the first threaded rod includes a first cylindrical rod body, and a first spiral thread is provided on the outer circumference of the first cylindrical rod body; the second threaded rod includes a second cylindrical rod body, and a second spiral thread is provided on the outer circumference of the second cylindrical rod body.
[0029] Through the design of interference fit plus spiral threads, the stress distribution between the threaded rod and the transmission belt is made more uniform.
[0030] Further, a first taper guiding portion is provided at one end of the first cylindrical rod body away from the convex type live joint, and a second taper guiding portion is provided at one end of the second cylindrical rod body away from the concave type connecting seat.
[0031] Through the design of the first taper guiding portion and the second taper guiding portion, it plays a guiding role when inserting the threaded rod into the transmission belt, making the insertion process smoother, reducing the installation difficulty, reducing the possibility of damage to the transmission belt and the threaded rod caused by forced insertion, and improving the installation efficiency.
[0032] Further, anti-slip threads are provided on the surfaces of the first threaded rod and the second threaded rod.
[0033] The anti-slip threads increase the contact area between the threaded rod and the inner wall of the installation hole of the transmission belt, thereby significantly increasing the friction force between the two.
[0034] In summary, the present invention includes at least one of the following beneficial technical effects:
[0035] 1. The present invention discloses a quick-release live joint for a transmission belt, which realizes the quick disassembly and assembly of the transmission belt joint through the spherical joint of the convex component and the spherical hinge connection of the concave component.

[0049] Embodiment 1:
[0050] Referring to Figure 1 、 Figure 2 , a quick-release flexible joint for a transmission belt disclosed in the present invention includes a convex flexible joint assembly 1 and a concave flexible joint assembly 2. One end of the convex flexible joint assembly 1 and one end of the concave flexible joint assembly 2 are detachably connected in a ball hinge manner.
[0051] Referring to Figure 7 , the other end of the convex flexible joint assembly 1 and the other end of the concave flexible joint assembly 2 are respectively fixedly connected to the transmission belt 5. The transmission belt 5 is a round belt made of a flexible material, such as rubber or polyurethane, so that the transmission belt 5 meets the deformation requirements and has a rebound characteristic.
[0052] Referring to Figure 1 、 Figure 2 , the ball hinge connection between the convex flexible joint assembly 1 and the concave flexible joint assembly 2 allows multi-degree-of-freedom rotation and is detachable at the same time, which is convenient for the installation, maintenance and replacement of the transmission belt 5 and improves work efficiency.
[0053] Referring to Figure 3 、 Figure 4 and Figure 7 , the convex flexible joint assembly 1 includes an integrally formed convex flexible joint 11, a prismatic connecting platform 12 and a first threaded rod 13. The convex flexible joint 11 has a spherical structure, and the surface of the spherical structure is roughened; one end of the prismatic connecting platform 12 is connected to the convex flexible joint 11, and the other end is connected to the first threaded rod 13; the prismatic connecting platform 12 is fixedly connected to the conveyor belt 5, and the first threaded rod 13 is inserted into the transmission belt 5, further strengthening the firmness of the connection and preventing the convex flexible joint assembly 1 from detaching from the transmission belt 5.
[0054] Referring to Figure 2 and Figure 4 , a cylinder 14 is provided at the neck of the convex flexible joint 11. Two symmetric rectangular grooves 141 are formed on the outer surface of the cylinder 14 in a direction perpendicular to the axial direction. The transverse width of the cylinder 14 is greater than the radial dimension of the top surface opening 2111.
[0055] Referring to Figure 2The distance between the two rectangular grooves 141 matches the width of the notch 212, and the rectangular grooves 141 and the notch 212 are aligned with each other with zero clearance, so that the male flexible joint 11 quickly slides into the accommodating cavity 211 from the notch 212 of the side opening 2112. The two rectangular grooves 141 are 180° symmetrical in the circumferential direction, and no matter the male flexible joint 11 is inserted at 0° or 180°, it can form an effective stop after rotating 90°, thus avoiding the directional limitation of the traditional single-groove design.
[0056] Reference Figure 2 , Figure 4 and Figure 6 During installation, align the notch of the rectangular groove 141 with the notch 212, quickly complete the preliminary docking, avoid misalignment and jamming during blind installation, and then slide it in axially. After the male flexible joint 11 enters the accommodating cavity 211, rotate the male flexible joint assembly 1 at a certain angle, the rectangular groove 141 and the notch 212 are misaligned, so that the male flexible joint 11 cannot be disengaged from the side; the lateral width of the cylinder 14 is greater than the radial dimension of the top surface opening 2111, which further prevents the male flexible joint 11 from being disengaged from the top surface opening 2111, thereby enhancing the firmness of the connection.
[0057] Reference Figure 5 and Figure 6 The concave flexible joint assembly 2 includes an integrally formed concave connecting seat 21 and a second threaded rod 22; the concave connecting seat 21 is prismatic; a receiving cavity 211 is provided inside the concave connecting seat 211, and the receiving cavity 211 can be a spherical receiving cavity, and the receiving cavity 211 is connected to the ball head and ball joint of the convex flexible joint 11; the concave connecting seat 21 is fixedly connected to the conveyor belt, and the second threaded rod 22 is inserted into the transmission belt 5.
[0058] Reference Figure 5 and Figure 6 The accommodating cavity 211 is designed with a top opening 2111 and a side opening 2112. A notch 212 is provided at the top of the side opening 2112. The accommodating cavity 211 forms an L-shaped connecting opening structure of "top opening 2111+side opening 2112+notch 212".
[0059] The width of the top opening 2111 is smaller than the ball head diameter of the male flexible joint 11, which prevents the male flexible joint 11 from falling off the top surface during normal use, thereby ensuring the reliability of the connection; the width of the side opening 2112 is larger than the ball head diameter of the male flexible joint 11, and the height of the accommodating cavity 211 is larger than the ball head diameter of the male flexible joint 11, thereby providing sufficient space for the male flexible joint 11 to rotate in the accommodating cavity 211, thereby ensuring the flexibility of the connection.
[0060] Reference Figure 5The top edge of the top opening 2111 of the accommodating cavity 211 is provided with an arc slope 213 that rotates with the surface of the rectangular groove 141. When the ball head of the male flexible joint 11 is inserted from the side opening 2112, the arc slope 213 serves as a guiding structure to guide the ball head of the male flexible joint 11 to smoothly enter the accommodating cavity 211, avoiding jamming or alignment difficulties caused by right-angle edges; the arc slope 213 rotates with the surface of the rectangular groove 141 to provide an unobstructed contact surface for rotation, increase the steering angle of the male flexible joint assembly 1, avoid the restriction of the right-angle edge on the rotation angle, allow the male flexible joint 11 to rotate at multiple angles in the accommodating cavity 211, and at the same time reduce the friction resistance between the two, prevent wear caused by friction, and extend the service life of the male flexible joint 11.
[0061] Reference Figure 3 and Figure 5 The prismatic connecting platform 12 and the concave connecting seat 21 are both polyhedral structures, each with at least two symmetrical sides being planes, and the remaining sides can be inclined surfaces or curved surfaces. The plane sides are symmetrically distributed along the axis to form a clamping surface similar to a bolt head or a nut, which is convenient for positioning and fixing operations during installation and can be used with tools such as wrenches and pliers.
[0062] Reference Figure 3 and Figure 5 The upper and lower surface edges of the prismatic connecting platform 12 and the concave connecting seat 21 are in an arc transition shape; the radial dimension of the prismatic connecting platform 12 is larger than the outer diameter of the first threaded rod 13; the radial dimension of the concave connecting seat 21 is larger than the outer diameter of the second threaded rod 22.
[0063] Reference Figure 7 and Figure 2 When the first threaded rod 13 and the second threaded rod 22 are respectively inserted into the transmission belt 5, the hole wall of the transmission belt 5 is stretched open, and the boss structure of the prismatic connection platform 12 and the concave connection seat 21 limits the excessive expansion of the hole wall, ensuring the long-term effectiveness of the interference fit and avoiding loosening due to vibration or wear. The outer diameters of the first threaded rod 13 and the second threaded rod 22 are both larger than the hole diameter of the transmission belt 5, and are connected to the transmission belt 5 by interference fit. The interference fit makes the first threaded rod 13 and the second threaded rod 22 tightly connected to the transmission belt 5. At the same time, the friction force generated by the interference fit can effectively prevent the relative displacement between the threaded rod and the transmission belt 5, ensuring the reliability of the connection between the convex flexible joint assembly 1 and the concave flexible joint assembly 2 and the transmission belt 5, and can stably transmit power during the transmission process.
[0064] Reference Figure 1 and Figure 2, the first threaded rod 13 and the second threaded rod 22 have the same structure; the first threaded rod 13 includes a first cylindrical rod body 131, and a first spiral thread 132 is provided on the outer periphery of the first cylindrical rod body 131; the second threaded rod 22 includes a second cylindrical rod body 221, and a second spiral thread 222 is provided on the outer periphery of the second cylindrical rod body 221. The first spiral thread 132 and the second spiral thread 222 play an important role when in interference fit with the transmission belt 5, increasing the contact area and friction force between the first threaded rod 13 and the second threaded rod 22 and the transmission belt 5, making the connection tighter and more secure.
[0065] The interference fit combined with the design of the spiral thread makes the stress distribution between the threaded rod and the transmission belt 5 more uniform. When the transmission belt 5 is subjected to tensile force, the spiral thread can disperse the stress over a larger area, avoiding local stress concentration, thereby reducing the possibility of the transmission belt 5 being damaged due to excessive stress. In a transmission system with a large load, the uniform stress distribution can extend the service life of the transmission belt 5. In a high-speed rotating transmission system, this reliable connection can ensure the stability of the transmission and avoid failures caused by loose connections.
[0066] Refer to Figure 1 and Figure 2 , at one end of the first cylindrical rod body 131 away from the convex joint 11, a first taper guiding portion 3 is provided, and at one end of the second cylindrical rod body 221 away from the concave connecting seat 21, a second taper guiding portion 4 is provided.
[0067] The first taper guiding portion 3 and the second taper guiding portion 4 usually adopt a taper angle, and the end diameter is slightly smaller than the aperture diameter of the transmission belt 5. They play a guiding role when inserting the first threaded rod 13 and the second threaded rod 22 into the transmission belt 5 respectively, making the insertion process smoother, reducing the installation difficulty, and reducing the possibility of damage to the transmission belt 5 and the first threaded rod 13 and the second threaded rod 22 caused by forced insertion, and improving the installation efficiency.
[0068] The first taper guiding portion 3 and the second taper guiding portion 4 form a wedge-shaped guide when inserting into the conveyor belt, elastically expanding the orifice of the transmission belt 5, which is especially suitable for transmission belts 5 made of elastic materials such as rubber.
[0069] Anti-slip threads are provided on the surfaces of the first threaded rod 13 and the second threaded rod 22. The anti-slip threads increase the contact area between the threaded rod and the inner wall of the installation hole of the transmission belt 5, thereby significantly increasing the friction force between the two. For example, in a high-speed rotating transmission system, without anti-slip threads, the first threaded rod 13 and the second threaded rod 22 may gradually loosen due to vibration, affecting the stability and reliability of the transmission; with anti-slip threads, the risk of such loosening can be greatly reduced.
[0070] The installation process of a quick-release joint for a transmission belt:
[0071] First, pre-align the openings at both ends of the transmission belt 5, and respectively sleeve the two ends of the transmission belt 5 on the first threaded rod 13 of the convex flexible joint assembly 1 and the second threaded rod 22 of the concave flexible joint assembly 2. Use the self-centering function of the first tapered guide portion 3 and the second tapered guide portion 4 to ensure that the first threaded rod 13 and the second threaded rod 22 are preliminarily aligned with the aperture of the transmission belt 5, respectively. Use tools such as wrenches to clamp the flat parts of the prismatic connecting platform 12 and the concave connecting seat 21 to tighten or fix them.
[0072] Next, the first threaded rod 13 and the second threaded rod 22 are pressed into the interior of the transmission belt 5. The interference fit design allows the transmission belt 5 to elastically deform to form a sealed and anti-loose connection. The anti-slip grooves on the surface of the threaded rods enhance the friction of manual operation.
[0073] Next, align the ball head of the male flexible joint 11 with the side opening 2112 of the female connector 21, and use the notch 212 to guide the cylinder 14 to slide into the accommodating cavity 211. Push the male flexible joint assembly 1 in the horizontal direction, so that the male flexible joint 11 enters the accommodating cavity 211 through the notch 212 of the side opening 2112, and then rotate the male flexible joint 11 so that the rectangular groove 141 is misaligned with the notch 212. At this time, the lateral width of the cylinder 14 is larger than the radial dimension of the top opening 2111, forming a mechanical interlock and completing the circumferential limit.
[0074] The ball head of the convex movable joint 11 contacts the arc slope 213 of the edge of the top surface opening 2111, achieving low-friction rotation and allowing the transmission belt 5 to be adaptively adjusted in pitch of ±15° and deflection of ±10°.
[0075] A disassembly process of a quick-release flexible joint of a transmission belt: first, rotate the convex flexible joint assembly 1 to realign the rectangular groove 141 with the notch 212, and pull out the convex flexible joint 11 horizontally along the side opening 2112. The ball head of the convex flexible joint 11 can be easily disengaged through the wider side opening 2112. The disassembly process does not require tools and is time-saving.
[0076] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, material, and principle of the present invention should be included in the protection scope of the present invention.
