Description

Technical Field

[0001] This utility model belongs to the field of linkage shaft technology, and in particular relates to a torque-balanced linkage shaft. Background Technology

[0002] A torque-balancing linkage shaft is a mechanical structure used to achieve uniform torque distribution among multiple power output ends or rotating parts. It is commonly used in transmission systems requiring smooth power transmission and load balancing. Torque-balancing linkage shafts are typically used in conjunction with couplings, synchronization mechanisms, or differential mechanisms to achieve their function. Due to their complex structure and susceptibility to damage, the torque-balancing effect deteriorates after prolonged use. Repair costs are high after damage, and they are essentially rendered unusable after failure. Utility Model Content

[0003] The purpose of this invention is to provide a torque balancing linkage shaft, which locks the balance disc by pressing the torque balancing component against the balance disc, and allows the balance disc to slide by pushing the torque balancing component against the balance disc with the upper push rod. This solves the problems of existing linkage shafts being complex in structure, easily damaged, and having poor torque balancing effect after long-term use.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a torque balancing linkage shaft, comprising a drive disc, a torque balancing sleeve, a torque balancing assembly, and a driven shaft disc. The drive disc has a snap-fit ​​connector at its front end and a drive shaft connected to its rear end. The torque balancing sleeve has an insertion groove on its side corresponding to the drive disc. The insertion groove has four limiting blocks evenly distributed on its inner wall, forming a fan-shaped groove between adjacent limiting blocks. A rubber gasket is inserted into the fan-shaped groove. The snap-fit ​​connector is snapped into the insertion groove and abuts against the rubber gasket. The torque balancing sleeve has a disc cavity on its side corresponding to the driven shaft disc. The driven shaft disc includes a driven shaft and a balancing disc. One end of the driven shaft is fixedly connected to the axis of the outer side of the balancing disc. A sealing plate is movably fitted on the driven shaft. The balancing disc is inserted into the disc cavity and seals the sealing plate on one side of the torque balancing sleeve on the side of the disc cavity. The torque balancing sleeve has four assembly slots evenly distributed on its outer wall corresponding to the limiting blocks. The torque balancing assembly is installed in the assembly slot and a slot cover is sealed at the slot opening.

[0005] The present invention is further configured such that the component slot is a square slot, and mounting platforms are provided on both side walls of the slot opening; upper top member insertion holes are provided on both side walls of the limiting block and extend into the component slot; a square through hole communicating with each component slot is provided on the inner side wall of the disc cavity; the torque balancing component includes an elastic compression locking disc component, an elastic limiting component, and an upper top rod; the elastic compression locking disc component is installed in the square through hole and presses against the balancing disc; the elastic limiting component is installed in the component slot; the top of the elastic compression locking disc component is fixedly connected to the bottom of the elastic limiting component; the upper top rod is inserted from the upper top member insertion hole and abuts against the bottom of the elastic limiting component; and the slot cover is fixed to the mounting platform with bolts.

[0006] The present invention is further configured such that the elastic limiting member includes a limiting plate and multiple limiting springs, the upper surface of the limiting plate having multiple limiting springs arranged in an array, the limiting plate being inserted into the component groove, and the bottom of the groove cover pressing the limiting springs so that the limiting plate abuts against the bottom of the component groove.

[0007] The present invention is further configured such that one end of the upper push rod is a wedge-shaped head, and the two side walls of the limiting plate 7 are provided with oblique cuts at the corresponding upper push member insertion holes, and the wedge-shaped head is inserted into the oblique cuts.

[0008] The present invention is further configured such that the elastic compression locking disc component includes a mounting block, a first arc plate, a second arc plate, and compression springs. The first arc plate is fixed to the bottom of the mounting block, and the first arc plate and the second arc plate are connected by multiple compression springs arranged in an array. The top of the mounting block is fixedly connected to the bottom of the limiting plate, and the mounting block is inserted into a square through hole. The lower surface of the second arc plate is in contact with the side wall of the equalizer disc.

[0009] The present invention is further configured such that a friction pad is attached to the lower surface of the equalizer, and the equalizer is a steel disc.

[0010] This utility model has the following beneficial effects: This utility model features a snap-fit ​​connector with four push blocks that engage within a sector-shaped groove to apply balanced force to the drive disc. The presence of rubber pads prevents the drive disc from generating a large instantaneous pulling force. The equalizing disc is not fixedly connected to the drive disc but rather elastically connected to the torque equalization component. When the driving force is below a certain value, the equalizing disc locks, driving the driven shaft to rotate. When the driven shaft becomes stuck, the snap-fit ​​connector creates significant resistance, squeezing the rubber pad. At this point, the upper push rod pushes into the component groove, causing the elastic limiting component to move upwards. This reduces the pressure on the equalizing disc, allowing relative sliding between the equalizing disc and the elastic squeezing locking component, preventing the equalizing disc from locking and reducing the likelihood of the linkage shaft jamming. The design is simple, durable, and has a long service life.

[0011] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-8 This utility model relates to a torque-balancing linkage shaft, comprising a drive disc 1, a torque-balancing sleeve 2, a torque-balancing assembly 100, and a driven shaft disc. The drive disc 1 has a snap-fit ​​connector 11 at its front end and a drive shaft connected to its rear end. The torque-balancing sleeve 2 has an insertion groove 21 on its side corresponding to the drive disc 1. The insertion groove 21 has four equally spaced limiting blocks 22 on its inner wall, forming a fan-shaped groove 211 between adjacent limiting blocks 22. A rubber pad 6 is inserted into the fan-shaped groove 211. The snap-fit ​​connector 11 is engaged within the insertion groove 21 and abuts against the rubber pad 6. The torque-balancing... The sleeve 2 has a cavity on the side corresponding to the driven shaft disk. The driven shaft disk includes a driven shaft 4 and an equalizing disk 41. One end of the driven shaft 4 is fixedly connected to the axis of the outer side of the equalizing disk 41. A sealing plate 5 is movably sleeved on the driven shaft 4. The equalizing disk 41 is inserted into the cavity and the sealing plate 5 is sealed on one side of the torque equalizing sleeve 2 on the cavity side. Four component slots 23 are evenly distributed on the outer wall of the torque equalizing sleeve 2 at the position corresponding to the limiting block 22. The torque equalizing component 100 is installed in the component slot 23 and the slot cover 3 is sealed at the slot opening of the component slot 23.

[0024] During connection, the snap-fit ​​connector 11 is snapped into the insertion slot 21. The side wall of the snap-fit ​​connector 11 contacts the side wall of the rubber pad 6 and the limiting block 22. Driven by the drive disc 1, the four protrusions of the snap-fit ​​connector 11 press against the rubber pad 6 on the side of the limiting block 22, thereby pushing the limiting block 22. The four limiting blocks 22 are evenly stressed, causing the drive disc to rotate. Because the torque balancing component 100 locks the balancing disc under a certain small driving force, the balancing disc 41 is driven to rotate, thereby causing the driven shaft 4 to rotate.

[0025] When the driven shaft 4 gets stuck or cannot rotate normally, the drive disc will experience greater resistance. The clamping joint will squeeze the rubber pad 6, which will drive the torque balancing component, reducing the degree of locking of the balancing disc 41. As a result, the balancing disc 41 will slide and rotate, thus preventing the linkage shaft from getting stuck.

[0026] The component slot 23 is a square slot. Mounting platforms 25 are provided on both sides of the slot opening of the component slot 23. The upper pusher insertion holes 221 are provided on both sides of the limiting block 22, and the insertion holes extend into the component slot 23. The inner side wall of the disk cavity is provided with a square through hole 24 communicating with each component slot 23. The torque equalization component 100 includes an elastic compression locking disc component 8, an elastic limiting component, and an upper pusher rod 9. The elastic compression locking disc component 8 is installed in the square through hole 24 and presses against the equalization disc 41. The elastic limiting component is installed in the component slot 23. The top of the elastic compression locking disc component 8 is fixedly connected to the bottom of the elastic limiting component. The upper pusher rod 9 is inserted from the upper pusher insertion hole 221 and abuts against the bottom of the elastic limiting component. The slot cover 3 is fixed to the mounting platform 25 with bolts.

[0027] The elastic limiting member limits the position of the elastic compression locking disc 8, so that the elastic compression locking disc 8 tightly holds the equalizer disc 41. When the upper push rod 9 is squeezed and pushed into the component groove 23, it lifts the elastic limiting member to a certain height. The elastic compression locking disc 8 will move a certain distance toward the component groove 23, so that the elastic compression locking disc 8 holds the equalizer disc 41 less tightly, and the equalizer disc 41 will slip to drive the rotation.

[0028] The elastic limiting component includes a limiting plate 7 and multiple limiting springs 71. Multiple limiting springs 71 are arranged in an array on the upper surface of the limiting plate 7. The limiting plate 7 is stuck in the component groove 23. The bottom of the groove cover 3 presses the limiting springs 71 so that the limiting plate 7 abuts against the bottom of the component groove 23.

[0029] The compressive force of the multiple limiting springs 71 is greater than the upward displacement force of the elastic compressive locking disc 8. Only when the upper push rod 9 is inserted into the component groove and pushes the limiting plate 7 up to a certain height will the multiple limiting springs 71 deform, and the top of the elastic compressive locking disc 8 will move slightly upward.

[0030] One end of the upper push rod 9 is a wedge-shaped head, and the two side walls of the limiting plate 7 are provided with oblique cuts 72 at the positions corresponding to the upper push member insertion holes 221, and the wedge-shaped head is inserted into the oblique cuts 72.

[0031] The wedge head tilt angle and the oblique cut angle 72 are both 45°. Pushing the upper push rod 9 inward will cause the limiting plate 7 to move upward. When the upper push rod 9 is not under force, the wedge head will be pressed down again, causing the upper push rod 9 to be retracted to its initial position.

[0032] The elastic compression locking disc component 8 includes a mounting block 81, a first arc plate 811, a second arc plate 83, and compression springs 82. The first arc plate 811 is fixed to the bottom of the mounting block 81. The first arc plate 811 and the second arc plate 83 are connected by multiple compression springs 82 arranged in an array. The top of the mounting block 81 is fixedly connected to the bottom of the limiting plate 7 and the mounting block 81 is inserted into the square through hole 24. The lower surface of the second arc plate 83 is in contact with the side wall of the equalizer 41.

[0033] When the mounting block 81 moves slightly upward, the first arc plate 811 moves upward synchronously, the compression degree of the compression spring 82 decreases, the compression friction of the second arc plate 83 on the balance plate 41 decreases, and the balance plate 41 will slip. Thus, when the driven shaft 4 encounters resistance, it will not generate a large torque on the drive plate 1, reducing damage to the drive plate 1.

[0034] A friction pad is attached to the lower surface of the balance disc 41, which is a steel disc. The friction pad, similar to a brake pad, rubs against the balance disc 41. Normally, it is locked. Moving the mounting block 81 upward reduces the degree of locking.
