Description

Technical Field

[0001] This utility model relates to the field of gear technology, specifically to a double spur gear backlash elimination and synchronization device. Background Technology

[0002] The double spur gear backlash elimination synchronization device mainly consists of two spur gears and a backlash elimination mechanism. Through the action of the backlash elimination mechanism, the backlash between the driving gear and the driven gear can be eliminated, thereby realizing backlash-free transmission.

[0003] Currently, existing double spur gear backlash elimination synchronization devices are complex to operate when fixed. The installation of the fixing parts requires ensuring a tight fit between the gear shaft and the fixing parts to avoid loosening or gaps. This requires the use of special installation tools and methods, which also increases the complexity of operation and technical requirements. In view of this, we propose a double spur gear backlash elimination synchronization device. Utility Model Content

[0004] The main objective of this invention is to provide a double spur gear backlash elimination and synchronization device that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a double spur gear backlash elimination and synchronization device, including a synchronization transition plate, a bracket mounted on the synchronization transition plate, an encoder mounted on the bracket, an orientation synchronization shaft mounted on the synchronization transition plate, screws threadedly connected to the synchronization transition plate, a coupling below the encoder, a backlash elimination gear one and a backlash elimination gear two respectively mounted on the coupling, a spring one installed between the backlash elimination gear one and the backlash elimination gear two, an auxiliary mechanism mounted on the backlash elimination gear one, the auxiliary mechanism including a retaining ring, the retaining ring being fixedly connected above the backlash elimination gear one.

[0006] Preferably, a fixing plate is fixedly connected to the inner wall of the bracket, and a square plate is fixedly connected above the fixing plate.

[0007] Preferably, the fixed plate is provided with a sliding groove, the sliding groove is also connected to a connecting plate, the connecting plate is fixedly connected to an arc-shaped toothed plate, and the side wall of the connecting plate is fixedly connected to a connecting rod.

[0008] Preferably, a locking block is fixedly connected to the side wall of the fixing plate.

[0009] Preferably, connecting blocks are fixedly connected to both side walls of the connecting plate, auxiliary blocks are fixedly connected to the connecting blocks, and sliding grooves are provided on the connecting blocks.

[0010] Preferably, the slide groove is slidably connected to a locking block, and a second spring is fixedly connected to the side wall of the locking block. The end of the second spring away from the side wall of the locking block is fixedly connected to an auxiliary block. An elastic telescopic rod is fixedly connected to the connecting plate, and a long plate is fixedly connected to the end of the elastic telescopic rod away from the connecting plate, and the long plate is fixedly connected to the fixed plate. By pulling the connecting rod upwards, the arc-shaped locking plate is moved away from the locking ring, thereby releasing the position limit on the backlash-eliminating gear one. As the connecting rod moves upwards, it also drives the locking block upwards simultaneously. With the cooperation of the slide groove and the second spring, the locking block engages with the locking block, thus completing the process. The position of the connecting plate is fixed, thereby fixing the position of the arc-shaped toothed plate. Then, the position between the backlash-eliminating gear one and the backlash-eliminating gear two is controlled by the encoder, the azimuth synchronous shaft and the coupling. The preload of the spring one between the backlash-eliminating gear one and the backlash-eliminating gear two eliminates the backlash in the transmission with the main shaft gear. After the backlash elimination is completed, the connecting rod is released and pushed down to release the locking block from the locking block. Under the elastic reset action of the elastic telescopic rod, the connecting plate will be driven to reset downward, so that the arc-shaped toothed plate is re-locked into the toothed ring, thus completing the position fixing of the backlash-eliminating gear one. The operation is simple and convenient.

[0011] This invention provides a double spur gear backlash-eliminating synchronization device. It has the following beneficial effects:

[0012] (1) The double spur gear backlash elimination synchronization device moves the arc-shaped toothed plate away from the toothed ring by pulling the connecting rod upward, thereby releasing the position limit of the backlash elimination gear one. When the connecting rod moves upward, it will drive the locking block to move upward at the same time. With the cooperation of the slide groove and the second spring, the locking block will be locked on the locking block, thereby completing the fixation of the position of the connecting plate, and then completing the fixation of the position of the arc-shaped toothed plate. Then, the position between the backlash elimination gear one and the backlash elimination gear two is controlled by the encoder, the azimuth synchronous shaft and the coupling. The backlash is eliminated by the pretension of the spring one between the backlash elimination gear one and the backlash elimination gear two and the transmission of the main shaft gear. After the backlash elimination work is completed, the connecting rod is released and pushed down to release the locking block from the locking block. Under the elastic reset action of the elastic telescopic rod, the connecting plate will be driven to reset downward, thereby making the arc-shaped toothed plate re-locked into the toothed ring, thus completing the fixation of the position of the backlash elimination gear one. The operation is simple and convenient.

[0013] (2) The double spur gear backlash elimination synchronization device can better connect with the tooth ring by setting two sets of arc-shaped tooth plates, thereby making the fixing effect of the backlash elimination gear one better. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4This utility model proposes a double spur gear backlash elimination synchronization device, including a synchronization transition plate 1, a bracket 2 mounted on the synchronization transition plate 1, an encoder 3 mounted on the bracket 2, an orientation synchronization shaft 9 mounted on the synchronization transition plate 1, a screw 8 threadedly connected to the synchronization transition plate 1, a coupling 10 below the encoder 3, a backlash elimination gear 4 and a backlash elimination gear 5 respectively mounted on the coupling 10, a spring 6 installed between the backlash elimination gear 4 and the backlash elimination gear 5, an auxiliary mechanism 7 mounted on the backlash elimination gear 4, the auxiliary mechanism 7 including a retaining ring 71, the retaining ring 71 being fixedly connected above the backlash elimination gear 4.

[0024] In the embodiments of this utility model, in order to assist the mechanism 7 to operate better, specifically, a fixing plate 72 is fixedly connected to the inner wall of the bracket 2, a square plate is fixedly connected above the fixing plate 72, a sliding groove is provided on the fixing plate 72, a connecting plate 73 is also connected to the sliding groove, an arc-shaped locking plate 74 is fixedly connected to the connecting plate 73, a connecting rod 75 is fixedly connected to the side wall of the connecting plate 73, a locking block 76 is fixedly connected to the side wall of the fixing plate 72, connecting blocks 77 are fixedly connected to both side walls of the connecting plate 73, an auxiliary block 78 is fixedly connected to the connecting block 77, and a sliding groove 79 is provided on the connecting block 77.

[0025] Furthermore, a locking block 710 is slidably connected to the slide groove 79. A second spring 711 is fixedly connected to the side wall of the locking block 710. The end of the second spring 711 away from the side wall of the locking block 710 is fixedly connected to the auxiliary block 78. An elastic telescopic rod 712 is fixedly connected to the connecting plate 73. A long plate 713 is fixedly connected to the end of the elastic telescopic rod 712 away from the connecting plate 73, and the long plate 713 is fixedly connected to the fixed plate 72. By pulling the connecting rod 75 upward, the arc-shaped toothed plate 74 is moved away from the toothed ring 71, thereby releasing the position limit on the backlash-free gear 4. As the connecting rod 75 moves upward, it will drive the locking block 710 to move upward at the same time. With the cooperation of the slide groove 79 and the second spring 711, the locking block 710 will lock into the locking plate 78. The position of the connecting plate 73 is fixed on block 76, thereby fixing the position of the arc-shaped toothed plate 74. Then, the position between the backlash-eliminating gear 1 4 and the backlash-eliminating gear 2 5 is controlled by the encoder 3, the azimuth synchronous shaft 9 and the coupling 10. The pre-tension of the spring 1 6 between the backlash-eliminating gear 1 4 and the backlash-eliminating gear 2 5 eliminates backlash in the transmission with the main shaft gear. After the backlash elimination is completed, the connecting rod 75 is released and pushed down to release the locking block 710 from the locking block 76. Under the elastic reset action of the elastic telescopic rod 712, the connecting plate 73 will be driven to reset downward, thereby allowing the arc-shaped toothed plate 74 to re-lock into the toothed ring 71, thus completing the position fixation of the backlash-eliminating gear 1 4. The operation is simple and convenient.

[0026] In this utility model, during use, the connecting rod 75 is first pulled upwards to move the arc-shaped toothed plate 74 away from the toothed ring 71, thereby releasing the position limit on the backlash-free gear 4. Simultaneously, the connecting rod 75 moves upwards, causing the locking block 710 to move upwards as well. With the cooperation of the sliding groove 79 and the second spring 711, the locking block 710 engages with the locking block 76, thus fixing the position of the connecting plate 73, and subsequently fixing the position of the arc-shaped toothed plate 74. Then, the encoder 3, the azimuth synchronous shaft 9, and the connecting rod... The shaft assembly 10 controls the position between the backlash-eliminating gear 4 and the backlash-eliminating gear 5. The preload of the spring 6 between the backlash-eliminating gear 4 and the backlash-eliminating gear 5 eliminates the backlash in the transmission with the main shaft gear. After the backlash elimination is completed, the connecting rod 75 is released and pushed down to release the locking block 710 from the locking block 76. Under the elastic reset action of the elastic telescopic rod 712, the connecting plate 73 will be driven to reset downward, so that the arc-shaped locking plate 74 will be re-locked into the locking ring 71, thus completing the position fixation of the backlash-eliminating gear 4.
