Description

Technical Field

[0001] This application relates to the field of universal joints, and more particularly to a novel universal joint. Background Technology

[0002] Universal joints, also known as universal joints, are key components for transmitting power at varying angles. Through internal ball joints or cross joints, they allow power to be transmitted between two shafts at different angles and on different planes, effectively addressing the needs of shaft misalignment and angular transmission. Their core advantages lie in enhancing the flexibility of mechanical systems, such as adapting to angle changes caused by steering and vertical movement in automotive transmission systems; and in improving reliability, such as ensuring a stable connection between engines and propellers in the aerospace field. Depending on the application, universal joints can be categorized into cross universal joints (suitable for high torque transmission) and ball joints (achieving constant velocity transmission, commonly used in steering systems), and are widely used in industries such as automotive, construction machinery, and aerospace, becoming indispensable "joint" components in mechanical transmissions.

[0003] Currently, when installing universal joints with mounting shafts, most methods use multiple bolts for installation. This requires workers to screw multiple bolts into the installation position one by one, which is cumbersome, increases the workload of workers unnecessarily, and is not conducive to the use of the equipment. Therefore, we propose a new type of universal joint. Utility Model Content

[0004] The purpose of this invention is to provide a novel universal joint to solve the problems mentioned in the background art.

[0005] This utility model provides a novel universal joint, comprising:

[0006] The universal joint body has connecting shafts fixedly connected to both sides, outer shells fixedly connected to one side of each of the two connecting shafts, inner shells fixedly connected to one side of the inner wall of each of the two outer shells, and a common cover plate fixedly connected between the outer shells and the inner shells.

[0007] Multiple threaded sleeves are rotatably mounted on the outside of two housings, one end of each threaded sleeve extends into the inside of the two housings, and a threaded rod is rotatably mounted inside each threaded sleeve.

[0008] Two sets of rotating components are respectively disposed inside two housings and are used to drive multiple threaded sleeves to rotate.

[0009] By adopting the above technical solution, when it is necessary to connect the mounting shaft to the universal joint body, firstly, the mounting shaft is inserted into the inner shell. Then, the handle is held and rotated. The rotation of the handle drives the rotating shaft and the second gear to rotate. Since the second gear is meshed with the rack, the rotation of the second gear drives the rack to rotate. Since the rack is meshed with multiple first gears, the rotation of the rack drives multiple first gears and the threaded sleeve to rotate. The rotation of the threaded sleeve drives the threaded rod and the clamping block to move. At this time, the clamping block can fix the mounting shaft. The rubber pads prevent damage to the mounting shaft during fixing. With the above structure, the mounting shaft can be connected to the universal joint body. The installation operation is simple and quick, avoiding the drawbacks of the traditional method of using multiple bolts to install the mounting shaft, reducing unnecessary workload for workers, and making it more convenient for workers to use.

[0010] Preferably, the two outer shells are circular in shape, and the two inner shells are annular in shape.

[0011] By adopting the above technical solution, the outer shell and the inner shell are more compatible with the device through the use of a circular outer shell and an arc-shaped inner shell.

[0012] Preferably, a rotating shaft is rotatably mounted on the exterior of both housings, the bottom of each rotating shaft extends into the interior of the housing, and a second gear is fixedly connected to one end of each rotating shaft located inside the housing.

[0013] By adopting the above technical solution, the second gear can be driven to rotate by rotating the shaft.

[0014] Preferably, the rotating assembly includes a rack, the rack being circular in shape, the rack being rotatably mounted on one side of the inner wall of the housing, and a first gear being fixedly sleeved on the outside of a plurality of threaded sleeves, the plurality of first gears being meshed with the rack, and a second gear being meshed with the rack.

[0015] By adopting the above technical solution, since the second gear is meshed with the rack, the rotation of the second gear can drive the rack to rotate. Since the rack is meshed with multiple first gears, the rotation of the rack can drive the multiple first gears and the threaded sleeve to rotate.

[0016] Preferably, a handle is fixedly connected to the top of each of the two rotating shafts, and the handle is made of rubber.

[0017] By adopting the above technical solution and using a rubber grip, the rotating shaft can be made more stable when rotating.

[0018] Preferably, the inner walls of both inner shells are provided with multiple circumferentially distributed through holes, and the multiple threaded rods move within the multiple through holes respectively.

[0019] By adopting the above technical solution and through the multiple through holes, the threaded rod can be moved to the other side of the inner shell.

[0020] Preferably, one end of each of the plurality of threaded rods is fixedly connected to a clamping block, and one side of each of the plurality of clamping blocks is fixedly connected to a rubber pad.

[0021] By adopting the above technical solution and using the rubber pad, damage to the mounting shaft during fixing is avoided.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] Rotating the handle causes the shaft and second gear to rotate, which in turn drives the rack to rotate, causing multiple first gears and threaded sleeves to rotate. The rotation of the threaded sleeves causes the threaded rod and clamping block to move, thus fixing the mounting shaft in place. The rubber pads prevent damage to the mounting shaft during fixing. This structure allows the mounting shaft to be easily installed on the universal joint body, simplifying the installation process and reducing the time required. It avoids the drawbacks of traditional installations that require multiple bolts, reducing unnecessary workload for operators and making the machine easier to use. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0030] This application discloses a novel universal joint.

[0031] Reference Figure 1 , Figure 2 and Figure 3 A novel universal joint, comprising:

[0032] Universal joint body 1, with connecting shafts 2 fixedly connected to both sides of the universal joint body 1. The connecting shafts 2 are used to connect the universal joint body 1. A housing 3 is fixedly connected to one side of each of the two connecting shafts 2. The housing 3 is used to support the threaded sleeve 5. An inner shell 14 is fixedly connected to one side of the inner wall of each of the two housings 3. The inner shell 14 is used to divide the internal space of the housing 3. The same cover plate 15 is fixedly connected between the housing 3 and the inner shell 14. The cover plate 15 is used to seal between the housing 3 and the inner shell 14.

[0033] Multiple threaded sleeves 5 are rotatably installed on the outside of two housings 3. One end of each threaded sleeve 5 extends into the inside of the two housings 3. The threaded sleeves 5 are used for threaded connection with threaded rods 8. Threaded rods 8 are rotatably installed inside each of the multiple threaded sleeves 5. The threaded rods 8 are used to drive the clamping block 9 to move.

[0034] Two sets of rotating components are respectively housed inside the two outer shells 3 and are used to drive the rotation of multiple threaded sleeves 5. When it is necessary to connect the mounting shaft to the universal joint body 1, first insert the mounting shaft into the inner shell 14, then grasp and rotate the handle 12. The rotation of the handle 12 drives the rotating shaft 11 and the second gear 13 to rotate. Since the second gear 13 is meshed with the rack 4, the rotation of the second gear 13 drives the rack 4 to rotate. Since the rack 4 is meshed with multiple first gears 6, the rotation of the rack 4... The circular motion of the screw drives multiple first gears 6 and threaded sleeves 5 to rotate. The rotation of the threaded sleeves 5 drives the threaded rod 8 and clamping block 9 to move. At this time, the clamping block 9 can fix the mounting shaft. The rubber pad 10 prevents damage to the mounting shaft during fixing. With the above structure, the mounting shaft can be installed on the universal joint body 1. The installation operation is simple and quick, avoiding the drawbacks of traditional installation that requires multiple bolts, reducing unnecessary workload for workers, and making it more convenient for workers to use.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The two outer shells 3 are circular in shape, and the two inner shells 14 are annular in shape. By using the circular outer shells 3 and the arc-shaped inner shells 14, the outer shells 3 and the inner shells 14 can be more compatible with this device.

[0036] Reference Figure 1 , Figure 3 and Figure 4 Two rotating shafts 11 are rotatably mounted on the outside of the two outer shells 3. The bottom of the two rotating shafts 11 extends into the inside of the outer shell 3. A second gear 13 is fixedly connected to one end of the two rotating shafts 11 inside the outer shell 3. By rotating the rotating shafts 11, the second gear 13 can be driven to rotate.

[0037] Reference Figure 1 , Figure 2 and Figure 4 The rotating assembly includes a rack 4, which is circular in shape and is rotatably mounted on one side of the inner wall of the housing 3. Multiple threaded sleeves 5 are each fixedly fitted with a first gear 6, which meshes with the rack 4. A second gear 13 meshes with the rack 4. Because the second gear 13 meshes with the rack 4, the rotation of the second gear 13 can drive the rack 4 to rotate. Because the rack 4 meshes with the multiple first gears 6, the rotation of the rack 4 can drive the multiple first gears 6 and the threaded sleeves 5 to rotate.

[0038] Reference Figure 3 and Figure 4 Each of the two rotating shafts 11 has a handle 12 fixedly connected to its top. The handle 12 is made of rubber. The rubber handle 12 makes the rotating shaft 11 more stable when it rotates.

[0039] Reference Figure 4 The inner walls of both inner shells 14 are provided with multiple circumferentially distributed through holes 7. Multiple threaded rods 8 are respectively movable inside the multiple through holes 7. Through the multiple through holes 7, the threaded rods 8 can be moved to the other side of the inner shell 14.

[0040] Reference Figure 3 and Figure 4 Each of the multiple threaded rods 8 has a clamping block 9 fixedly connected to one end, and a rubber pad 10 fixedly connected to one side of each of the multiple clamping blocks 9. The rubber pad 10 is used to prevent damage to the mounting shaft during fixing.

[0041] The implementation principle of a novel universal joint according to an embodiment of this application is as follows: When it is necessary to connect the mounting shaft to the universal joint body 1, firstly, the mounting shaft is inserted into the inner shell 14. Then, the handle 12 is held and rotated. The rotation of the handle 12 drives the rotating shaft 11 and the second gear 13 to rotate. Since the second gear 13 is meshed with the rack 4, the rotation of the second gear 13 drives the rack 4 to rotate. Since the rack 4 is meshed with multiple first gears 6, the rotation of the rack 4 drives the multiple first gears 6 and the threaded sleeve 5 to rotate. The rotation of the threaded sleeve 5 drives the threaded rod 8 and the clamping block 9 to move. At this time, the clamping block 9 can fix the mounting shaft. The rubber pad 10 is provided to avoid damage to the mounting shaft during fixing. With the above structure, the mounting shaft can be connected to the universal joint body 1. The installation operation is simple and time-saving, avoiding the disadvantages of the traditional method that requires multiple bolts for installation, reducing unnecessary workload for workers, and making it more convenient for workers to use.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
