This embodiment is specially designed for heavy-load roller adjustment transmission and is suitable for use in heavy-duty roller equipment. First, the module uses the base plate 1 as the structural basis, and the through groove 11 cleverly arranged on it not only provides a flexible crossing path for the transmission roller 2, but also ensures the compactness and integration of the entire transmission system. This design enables the module to adapt to complex and changeable installation environments, and is convenient for subsequent maintenance and upgrading, greatly improving the space utilization and system flexibility. Secondly, the transmission roller 2 is connected to the through groove 11 on the base plate 1 through the roller connection component 5, realizing effective transmission and conversion of force. The connection component is made of high-strength material, ensuring good stability and durability under high load conditions, effectively avoiding loosening or damage caused by long-term heavy-load use, and further improving the service life and reliability of the module. The lifting transmission component 3 realizes efficient power transmission through the seamless connection between the lifting drive device 31 and the linkage device 32, ensuring the rapid response and smooth operation of the lifting action. The two sets of lifting and moving devices 33 are respectively placed on both sides of the through groove 11, which not only enhances the load-bearing capacity of the module, but also realizes synchronization and stability during the lifting process through the coordination of the linkage device 32, effectively preventing the occurrence of eccentric load and vibration. The setting of the lifting support device 34 further strengthens the supporting capacity of the module during the lifting process, ensuring that the roller can remain stable at any height, thus meeting the needs of high-precision adjustment. At the same time, the introduction of the lifting locking device 35 provides additional safety protection for the module. After lifting in place, the locking device can quickly and firmly fix the lifting and moving device 33, effectively preventing the roller from sliding down or moving due to unexpected situations, and ensuring the safety and stability of the entire transmission system.

[0040] In this embodiment, the addition of the lateral fine-tuning component 4 enables the module to achieve more precise transmission control through fine-tuning when dealing with different working environments and load conditions. This function not only improves production efficiency and product quality, but also provides users with greater operational flexibility and convenience. The present invention solves many problems in the transmission of heavy-duty roller adjustment. Its efficient, precise and stable transmission characteristics, as well as the advantages of easy maintenance, upgrading and high space utilization, make the module have broad application prospects and huge market potential in the fields of industrial automation, heavy machinery manufacturing, etc.

[0041] The lifting drive device 31 includes a driving motor 311 and a driving reducer 312. The linkage device 32 includes a gear box 321 and a plurality of linkage gears (not shown in the figure) arranged in the gear box 321.

The output shaft 322 is connected to the input end of the lifting and moving device 33. The driving reducer 312 is connected to the linkage gear (not shown in the figure) to drive the linkage gear (not shown in the figure) to drive the lifting and moving device 33 to drive. In this embodiment, the coordinated work of the driving motor 311 and the driving reducer 312 provides a strong and precise power source for the entire transmission system, ensuring the stable operation of the module under high load conditions. The driving reducer 312 effectively improves the efficiency and reliability of power transmission by slowing down the speed and increasing the torque, so that the module can still maintain a stable lifting action when facing a large mass load. The design of the gear box 321 in the linkage device 32 realizes efficient transmission and distribution of power through multiple precision meshing linkage gears (not shown in the figure) inside. This structure not only enhances the stability of the transmission, but also significantly reduces noise and vibration, and prolongs the service life of the module.

Secondly, the locking drive element 352 is arranged on one side of the substrate 1, and the lifting screw 333 is firmly locked by driving the locking pin 353 to be inserted into the locking socket 3511. This mechanism is particularly important in a high-load environment, as it can effectively prevent the screw from loosening or falling off due to excessive load, thereby improving the load-bearing capacity and safety of the module. In addition, the multiple locking sockets 3511 arranged circumferentially on the outer periphery of the locking disk 351 provide a variety of insertion options for the locking pin 353, thereby enhancing the reliability and flexibility of the locking.

The ingenious combination of the rolling groove 3325 and the sliding roller 3326 further reduces the wear of the contact surface, prolongs the service life, and ensures smooth operation under high load. In addition, the lifting screw 333 is made of high-strength and high-hardness materials such as SKD11 or DC53, and is quenched to a hardness of 56 to 60HRC. This feature enables the lifting screw 333 to maintain excellent mechanical properties and wear resistance under high-load and high-intensity working environments, thereby ensuring the long-term stable operation of the transmission module. The design of the frame-type thread groove 3331, combined with the appropriate pitch (2 to 4mm), not only optimizes the transmission efficiency of the lifting transmission seat 334, but also improves the response speed and accuracy of the system.

The introduction of the roller assembly enables the module to achieve more flexible and efficient control of the load during transmission, positioning and fine-tuning, especially in high-precision operation scenarios that require precise control of the load position and posture, and its technical advantages are particularly significant.

The lateral fine-tuning transmission device 43 comprises a lateral sliding block 431, and the lateral sliding block 431 is provided with a lateral sliding guide shaft 432, which is slidably arranged in the lateral adjustment cavity 411. The lateral sliding block 431 is connected to the lateral fine-tuning screw 422, and the lateral fine-tuning screw 422 is used to drive the lateral sliding block 431 to slide along the lateral sliding guide shaft 432 to push the lateral fine-tuning platform 44 to slide in the lateral adjustment cavity 411. In this embodiment, the lateral fine-tuning frame 41 provides a precise sliding track for the lateral fine-tuning platform 44 through its built-in lateral adjustment cavity 411, ensuring that the platform can still maintain stable and smooth lateral movement under high load conditions. This greatly enhances the adaptability and flexibility of the module in a complex working environment. Secondly, the design of the lateral fine-tuning transmission device 43, especially the combination of the lateral fine-tuning motor 421 and the lateral fine-tuning screw 422, realizes high-precision drive of the lateral sliding block 431. The efficient output of the motor is converted into the linear motion of the sliding block through the screw. This process is not only precisely controllable, but also responsive, meeting the strict requirements for fine-tuning speed and position accuracy under high load. Furthermore, the lateral sliding guide shaft 432 set on the lateral sliding block 431 further optimizes the friction and wear problems during the sliding process, ensuring long-term stability and durability. This design effectively reduces the heat and noise generated by friction and improves the operating efficiency of the entire transmission module.

When the lateral guide roller 433 rolls on the lateral adjustment groove 441, it drives the lateral fine-tuning platform 44 to move along the lateral adjustment cavity 411. In this embodiment, firstly, the rolling motion of the lateral guide roller 433 in the inclined lateral adjustment groove 441 provides an efficient and accurate lateral fine-tuning mechanism. This design not only simplifies the adjustment process, but also significantly improves the adjustment accuracy, so that the high-load linear transmission module can achieve more delicate lateral positioning and adjustment while maintaining a high load capacity. Secondly, the cooperation between the lateral guide roller 433 and the lateral adjustment groove 441 effectively disperses the stress generated by the module during the lateral fine-tuning process, and enhances the stability and durability of the system. Especially under high load conditions, this design can prevent the module from being deformed or damaged due to excessive lateral force, thereby extending the service life of the module. In addition, this structure also optimizes the adaptability of high-load linear transmission modules in complex working environments. Whether it is for precise adjustment in a small space or in application scenarios where the working direction needs to be frequently changed, the combination of the lateral sliding block 431 and the lateral fine-tuning platform 44 can provide stable and reliable lateral transmission support.

In scenarios where complex posture adjustments of the load are required, such as precision machining, optical positioning, automated assembly, etc., this component can ensure that the load object reaches the predetermined tilt angle with extremely high precision, thereby meeting specific process requirements. Secondly, the synergy between the tilt fine-tuning platform 64 and the tilt fine-tuning transmission device 63 significantly improves the stability of the load object during the tilt adjustment process. Driven by the tilt fine-tuning motor 621, the tilt fine-tuning screw 622 can smoothly and continuously push the tilt sliding block 631 to slide in the tilt adjustment cavity 611, thereby driving the tilt fine-tuning platform 64 to move along a predetermined trajectory.This smooth transmission method effectively avoids vibration and impact caused by rapid changes, ensuring the stability and safety of the load object during fine-tuning. In addition, the matching design of the tilt guide roller 633 and the tilt adjustment slot 641 not only further improves the movement accuracy of the tilt fine-tuning platform 64, but also significantly reduces friction resistance and extends the service life of the transmission system. The rolling of the tilt guide roller 633 on the tilt adjustment slot 641 makes the tilt fine-tuning platform 64 smoother and more flexible during movement, while reducing the heat and wear caused by friction and improving the transmission efficiency. In particular, the tilt adjustment of the roller shaft allows the roller shaft to tilt.
