Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a precise positioning follow-up balance transmission shaft support device. Background Technology

[0002] In modern mechanical transmission systems, the drive shaft is a crucial component connecting the power source and the working machinery. The stability and efficiency of its torque transmission directly affect the overall system performance. Drive shafts typically consist of multiple shaft segments and couplings, and during operation, factors such as speed, load, and vibration can cause eccentricity and imbalance. This imbalance not only increases energy loss but can also lead to equipment malfunctions or even damage, affecting the reliability and lifespan of the equipment.

[0003] Currently, some traditional drive shaft support devices mainly rely on rigid support structures. Although this method is simple, under high-speed or high-load operation, traditional support devices are prone to imbalance, which leads to increased vibration and noise of the drive shaft and further affects the stability of the entire system.

[0004] Therefore, this utility model provides a precise positioning follow-up balancing transmission shaft support device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a precise positioning follow-up balancing transmission shaft support device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a precise positioning follow-up balance transmission shaft support device, comprising a fixed seat and a movable seat; the movable seat is internally slidably connected with a pressure connection component;

[0007] The self-balancing component includes an outer ring fixedly connected to the inner side of the fixed seat and the movable seat. The outer ring has a groove inside, and multiple balance beads are slidably connected to the outer side of the groove. A connecting ring is slidably connected inside the multiple balance beads. Limit blocks are fixedly connected to both sides of the connecting ring near the balance beads. A slider is fixedly connected to the outer side of the balance beads.

[0008] In a preferred embodiment, the pressure connection assembly includes a screw slidably connected inside the movable seat, a spring sleeved on the outside of the screw, and washers fixedly connected to the four corners of the top of the movable seat.

[0009] In a preferred embodiment, one end of the spring is fixedly connected to the screw, and the other end of the spring is rotatably connected to the washer.

[0010] In a preferred embodiment, the outer thread of the screw is connected to the mounting base.

[0011] In a preferred embodiment, an inner ring is slidably connected to the inner side of the plurality of sliders, and a bearing is fixedly connected inside the plurality of inner rings.

[0012] In a preferred embodiment, the outer ends of the balance bead are in contact with the limiting block.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] This invention utilizes the compression of a spring, with the screw in the pressure connection assembly threaded onto the fixed seat, ensuring the movable seat returns to its original position when the drive shaft is under stress. At this time, the stress on the drive shaft causes the balance beads to slide within the groove, automatically adjusting their position according to the stress, thus achieving drive shaft balance. A connecting ring links multiple balance beads together, ensuring coordinated movement within the groove and enhancing overall balance. The slider moves the inner ring, thereby adjusting the bearing position; this design allows the balance beads to automatically adjust their position within the groove, dynamically adapting to changes in drive shaft stress, maintaining stable system operation, and reducing vibration and noise. Furthermore, the cooperation of the spring and pressure connection assembly allows for rapid restoration of the movable seat to its original position relative to the fixed seat, ensuring the stability of the support structure. This effectively reduces imbalances caused by vibration or uneven stress, significantly lowering drive shaft vibration and noise. Attached Figure Description

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.

[0026] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a precise positioning follow-up balance transmission shaft support device, including a fixed seat 1 and a movable seat 2; a pressure connection component 3 is slidably connected inside the movable seat 2, the pressure connection component 3 includes a screw 31 slidably connected inside the movable seat 2, the outer side of the screw 31 is threadedly connected to the fixed seat 1, a spring 32 is sleeved on the outer side of the screw 31, and washers 33 are fixedly connected to the four corners of the top of the movable seat 2, one end of the spring 32 is fixedly connected to the screw 31, and the other end of the spring 32 is rotatably connected to the washer 33;

[0027] The fixed seat 1 serves as the fixed base of the entire device, installed on the vehicle chassis or other fixed structure, providing a stable support point for the drive shaft and ensuring that the drive shaft will not experience excessive displacement or shaking during operation. The movable seat 2 works in conjunction with the fixed seat 1 and can move or adjust within a certain range to adapt to the slight changes or vibrations of the drive shaft during operation, thereby achieving precise positioning and dynamic balance of the drive shaft. The screw 31 connects the movable seat 2 and the fixed seat 1 tightly together through a threaded connection. At the same time, the position of the movable seat 2 can be adjusted by rotating the screw 31, thereby achieving precise positioning of the drive shaft. The spring 32 is sleeved on the outside of the screw 31, with one end fixed to the screw 31 and the other end connected to the washer 33. It can provide elastic support and buffering when the drive shaft is under force, reducing the vibration and impact of the drive shaft. The washer 33 is fixed at the four corners of the top of the movable seat 2 and rotatably connected to one end of the spring 32, playing a supporting and limiting role, while also dispersing the pressure of the spring 32 and protecting the connection between the movable seat 2 and the spring 32.

[0028] Self-balancing component 4; Self-balancing component 4 includes an outer ring 41 fixedly connected to the inner side of the fixed base 1 and the movable base 2. The outer ring 41 has a groove 42 inside. Multiple balance beads 43 are slidably connected to the outer side of the groove 42. A connecting ring 44 is slidably connected inside the multiple balance beads 43. Limiting blocks 45 are fixedly connected to both sides of the connecting ring 44 near the balance beads 43. The outer ends of the balance beads 43 are in contact with the limiting blocks 45. A slider 46 is fixedly connected to the outer side of the balance beads 43. An inner ring 47 is slidably connected to the inner side of the multiple sliders 46. A bearing 5 is fixedly connected inside the multiple inner rings 47.

[0029] The outer ring 41 is fixedly connected to the inner side of the fixed seat 1 and the movable seat 2, providing external support and a fixed foundation for the entire self-balancing assembly 4, ensuring the stability and integrity of the assembly. The slide groove 42 is formed inside the outer ring 41, providing a track and guide for the sliding of the balance beads 43, allowing the balance beads 43 to move along a specific path, thereby achieving the self-balancing function. Multiple balance beads 43 are slidably connected within the slide groove 42, automatically adjusting their position according to the force applied to the drive shaft to achieve the purpose of balancing the drive shaft, reducing vibration and offset of the drive shaft. The connecting ring 44 slides... The balance beads 43 are connected inside the balancing beads 43, allowing them to move in a coordinated manner within the slide groove 42, thus enhancing the overall balance of the self-balancing assembly 4. Limiting blocks 45 are fixedly connected inside the connecting ring 44, near both sides of the balance beads 43, limiting their movement and preventing excessive movement or derailment within the slide groove 42. Slider blocks 46 are fixedly connected to the outside of the balance beads 43, and inner rings 47 are slidably connected to the inner sides of multiple sliders 46. The sliding of the sliders 46 drives the inner rings 47 to move, achieving... The internal movement of the self-balancing component 4 involves multiple inner rings 47 slidably connected to the inner side of sliders 46. Bearings 5 ​​are fixedly connected inside the inner rings 47. The position of the bearings 5 ​​is adjusted by moving the inner rings 47, further optimizing the balance of the drive shaft. The bearings 5, fixedly connected inside the inner rings 47, provide support and rotation for the drive shaft. Simultaneously, the adjustment of the inner rings 47 maintains the stability and balance of the drive shaft. The number of balance beads 43 is between four and eight. This number provides sufficient balancing effect while avoiding excessive complexity and cost. For smaller devices, only four to six balance beads 43 are needed, while for larger devices or those requiring higher precision balancing, six to eight or more may be necessary. The number of sliders 46 typically matches the number of balance beads 43. Each balance bead 43 is fixedly connected to the outside of a slider 46, thus the number of sliders 46 is the same as the number of balance beads 43. The number of inner rings 47 also typically matches the number of balance beads 43 and sliders 46. Each slider 46 is slidably connected to the inside of an inner ring 47, thus the number of inner rings 47 is the same as the number of sliders 46.

[0030] like Figure 1 - Figure 4 As shown:

[0031] In use: First, the fixed seat 1 is installed on the vehicle chassis or other fixed structure to provide a stable support base for the drive shaft. Then, the movable seat 2 works in conjunction with the fixed seat 1, allowing it to move or adjust within a certain range to accommodate minor changes or vibrations in the drive shaft during operation. When the spring 32 is compressed, the screw 31 in the pressure connection assembly 3 is threaded onto the fixed seat 1, ensuring that the movable seat 2 and the fixed seat 1 can quickly return to their original positions. When the drive shaft is under force, the balance ball 43 slides within the groove 42, automatically adjusting its position according to the force applied to the drive shaft to achieve balance. The connecting ring 44 connects multiple balance balls 43 together, allowing them to move in a coordinated manner within the groove 42, enhancing the overall balance effect of the self-balancing assembly 4. The limiting block 45 limits the movement of the balance ball 43, preventing it from moving excessively within the groove 42 or leaving the track. The sliding of the slider 46 drives the inner ring 47 to move, adjusting the position of the bearing 5 and further optimizing the balance of the drive shaft.
