Description

Technical Field

[0001] This utility model relates to the field of gear backlash adjustment technology, and in particular to a gear backlash adjustment mechanism. Background Technology

[0002] In existing mechanical equipment, gear backlash adjustment is often a critical and complex step. Traditional gear backlash adjustment methods often rely on manual adjustment or simple mechanical structures, resulting in limited adjustment accuracy and susceptibility to external factors such as vibration and temperature changes, which can cause changes in gear backlash, affecting the operational stability and service life of the mechanical equipment. Furthermore, while some complex adjustment mechanisms can improve adjustment accuracy, they are often structurally complex and difficult to maintain, increasing user costs and complexity.

[0003] Furthermore, many existing gear backlash adjustment mechanisms are overly complex, containing numerous components and connecting structures. This not only increases the failure rate of the mechanism but also raises maintenance costs and time for users. Simultaneously, some mechanisms require users to possess advanced professional skills and operating experience, or to use specialized tools and equipment, undoubtedly increasing the difficulty and limitations of use. In addition, after prolonged use, some mechanisms often experience a decrease in adjustment accuracy or even malfunction due to component wear or aging, further increasing the user's maintenance burden. Therefore, we provide a gear backlash adjustment mechanism. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a gear backlash adjustment mechanism, which more precisely solves the problems mentioned in the background section.

[0005] This utility model is achieved through the following technical solution:

[0006] The utility model proposes a gear backlash adjustment mechanism, including a grooved mounting plate and a threaded rod rotatably connected to the grooved mounting plate via a bearing. A threaded sleeve block is threadedly sleeved around the threaded rod, and the threaded sleeve block is slidably connected to the inner wall of the grooved mounting plate. A placement groove is provided on the front of the threaded sleeve block, and a placement block is placed on the inner wall of the placement groove. The surface of the placement block is rotatably connected to the gear mounting rod via a bearing.

[0007] A mechanical interlock mechanism is connected between the threaded sleeve block and the placement block;

[0008] The mechanical interlocking mechanism includes a rectangular through slot formed on the end wall of the placement groove and a transverse through slot formed on the placement block. An arc-shaped limiting block is inserted into the inner wall of the storage slot for insertion into the inner wall of the rectangular through slot. A reset component is connected between the storage slot and the arc-shaped limiting block.

[0009] The threaded sleeve is connected to push-off components at both ends, which are used to push the arc-shaped limiting block away from the inner wall of the rectangular through groove.

[0010] Furthermore, the reset assembly includes a strip-shaped placement groove formed on the inner side wall of the receiving channel, a horizontal fixing rod fixedly connected between the two end walls of the strip-shaped placement groove, a spring sleeved around the horizontal fixing rod, and a sliding sleeve block slidably sleeved around the horizontal fixing rod.

[0011] Furthermore, the push-off component includes insertion holes formed on the surfaces of both ends of the threaded sleeve block. Insertion rods are inserted into the inner walls of the insertion holes. A spring is fixedly connected between the inner bottom wall of the insertion holes and one end surface of the insertion rods. Overlapping plates are fixedly connected to the ends of the two insertion rods. Pushing blocks are fixedly connected to the surfaces of the overlapping plates relative to the ends of the threaded sleeve blocks.

[0012] Furthermore, the push block is designed to be positioned relative to the rectangular through slot, and the size of the push block is adapted to the size of the rectangular through slot.

[0013] Furthermore, the sliding sleeve blocks are slidably connected to the inner wall of the strip-shaped mounting groove, and the opposing surfaces of the two sliding sleeve blocks are fixedly connected to the two side surfaces of the arc-shaped limiting block.

[0014] Furthermore, one end of the spring is fixedly connected to the end wall of the strip-shaped mounting groove, and the other end of the spring is fixedly connected to one end surface of the sliding sleeve block.

[0015] The beneficial effects of this utility model are:

[0016] This invention achieves precise axial movement control through the cooperation of the threaded rod and the threaded sleeve block; at the same time, the design of the mechanical interlock mechanism ensures the positional stability of the gear mounting rod after adjustment, preventing gap changes caused by vibration or external force; the synergistic effect of the reset component and the push-off component allows the user to easily unlock and relock when adjusting the gear gap, further improving the accuracy and stability of the adjustment.

[0017] This invention, through the design of the push-off component, allows users to easily unlock the mechanical interlock mechanism without the need for complex tools or skills; at the same time, the automatic reset function of the reset component reduces the user's operating steps and improves maintenance efficiency; in addition, the entire mechanism has a compact structure and fewer parts, reducing the failure rate and maintenance costs; this design makes the mechanism easy to maintain and convenient to operate, reducing the difficulty and cost for users.

[0022] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0023] Example

[0024] like Figures 1-3 As shown in the figure, an embodiment of the present invention discloses a gear backlash adjustment mechanism, which mainly includes a grooved mounting plate 1 and a threaded rod 2. The threaded rod 2 is rotatably connected to the grooved mounting plate 1 via a bearing, allowing it to rotate freely. A threaded sleeve block 3 is threadedly sleeved around the outer periphery of the threaded rod 2, and the threaded sleeve block 3 is slidably connected to the inner wall of the grooved mounting plate 1, ensuring that the threaded sleeve block 3 can move axially when the threaded rod 2 rotates. A placement groove 18 is provided on the front side of the threaded sleeve block 3 for placing a placement block 4. A gear mounting rod 5 is rotatably connected to the surface of the placement block 4 via a bearing, allowing the gear to rotate freely on the placement block 4; the mechanical interlocking mechanism consists of a rectangular through groove 6 opened on the end wall of the placement groove 18 and a transverse through groove 7 opened on the placement block 4. An arc-shaped limiting block 12 is inserted into the through groove 7, and when the arc-shaped limiting block 12 is inserted into the rectangular through groove 6, the threaded sleeve block 3 and the placement block 4 are locked. The reset component is used to automatically reset the arc-shaped limiting block 12 into the receiving slot 7 when needed. The push-off component is used to push the arc-shaped limiting block 12 out of the rectangular slot 6 when unlocking is required, thereby allowing the placement block 4 to move relative to the threaded sleeve block 3, and thus adjust the gear clearance. By rotating the threaded rod 2, the gear clearance can be precisely adjusted, while the mechanical interlock mechanism ensures the stability after adjustment.

[0025] Furthermore, the reset assembly includes a strip-shaped placement groove 8 formed in the inner wall of the receiving slot 7, and a horizontal retaining rod 9 is fixedly connected within the strip-shaped placement groove 8. A spring 10 is sleeved around the horizontal retaining rod 9 to provide a reset force. A sliding sleeve 11 is slidably sleeved around the horizontal retaining rod 9 and fixedly connected to the two side surfaces of the arc-shaped limiting block 12. When the arc-shaped limiting block 12 is pushed away from the rectangular slot 6, the spring 10 pushes the arc-shaped limiting block 12 back into the receiving slot 7 via the sliding sleeve 11. The reset assembly ensures that the arc-shaped limiting block 12 automatically returns to its initial position after unlocking, preparing for the next locking.

[0026] Furthermore, the release component includes insertion holes 13 formed on both ends of the threaded sleeve block 3, with insertion rods 14 inserted into the insertion holes 13. A spring 15 is fixedly connected between the inner bottom wall of the insertion hole 13 and one end surface of the insertion rod 14 to provide a pushing force. A lap plate 16 is fixedly connected to the ends of the two insertion rods 14, and a push block 17 is fixedly connected to the surface of the lap plate 16 relative to the end of the threaded sleeve block 3. When unlocking is required, the push block 17 is pulled outward, pushing the arc-shaped limiting block 12 out of the rectangular through slot 6 via the lap plate 16 and the insertion rods 14.

[0027] Furthermore, the design position of the push block 17 matches the relative position of the rectangular through slot 6, and the size of the push block 17 is adapted to the opening size of the rectangular through slot 6. This design ensures that the push block 17 can accurately align with and push the arc-shaped limiting block 12 when moving, thereby achieving unlocking.

[0028] Furthermore, the sliding sleeve 11 is slidably connected to the inner wall of the strip-shaped mounting groove 8, ensuring that the sliding sleeve 11 can move freely along the length of the strip-shaped mounting groove 8. At the same time, the opposing surfaces of the two sliding sleeves 11 are fixedly connected to the two side surfaces of an arc-shaped limiting block 12. This design allows the arc-shaped limiting block 12 to remain stable during movement and is connected to the horizontal fixing rod 9 and the spring 10 through the sliding sleeves 11.

[0029] Furthermore, one end of spring 10 is fixedly connected to the end wall of the strip-shaped mounting groove 8, and the other end is fixedly connected to one end surface of the sliding sleeve block 11. This design ensures that spring 10 can provide a stable reset force, allowing the arc-shaped limiting block 12 to automatically reset into the receiving slot 7 after unlocking. The connection method of spring 10 improves the reset effect and reliability of the reset assembly.
