Description

Technical Field

[0001] The utility model relates to the field of a rotating shaft concentricity adjusting device, in particular to an automatic rotating shaft concentricity adjusting device. Background Art

[0002] In the conveyor belt system, bearings and traction rollers are crucial components. They carry and transmit materials together to ensure the stable operation and long-term reliability of the conveyor belt. Bearings are devices that support and limit the movement of the shaft and are usually installed in key positions such as the drive shaft and tension shaft of the conveyor belt. They bear the weight and transmission force of the material on the shaft, while reducing friction and wear to ensure smooth rotation of the shaft. The traction roller is the main driving and bearing device on the conveyor belt, and its function is to transmit and support the transported materials. The traction roller on the conveyor belt is usually installed on the belt drum to drive the movement of the conveyor belt, while bearing the weight and transmission force of the material.

[0003] The bearings in traditional shafts are usually installed inside a specially designed seat, which is fixed to the structure of the conveyor belt through mounting holes. The bearings can be fixed inside the seat in various ways, including bolts or specially designed fixing fixtures. The traction roller is usually installed on the roller of the conveyor belt through a special bearing or bearing seat. These rollers are installed in the skeleton structure of the conveyor belt and are usually arranged at a certain distance to support the entire conveyor belt system.

[0004] However, the installation method of the bearing and the traction roller in the traditional shaft may have the problem of eccentricity, resulting in shaft grinding between the bearing and the traction roller, which not only causes serious mechanical wear and affects the stable operation of the shaft but also produces abnormal noise, reducing the practicality of this bearing installation method. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides an automatic adjustment device for the concentricity of a rotating shaft, which aims to improve the problem that the installation method of the bearing and the traction roller in the traditional rotating shaft may be non-concentric, resulting in the shaft grinding phenomenon between the bearing and the traction roller, which not only causes serious mechanical wear and affects the stable operation of the rotating shaft, but also produces abnormal noise, reducing the practicality of this bearing installation method.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an automatic adjustment device for the concentricity of a rotating shaft, comprising a fuselage frame, an active roller is rotatably connected inside the fuselage frame, bearing bodies are rotatably connected at both ends of the active roller, a bearing block A with a seat is arranged at one end of the bearing body, a bearing block B with a seat is arranged at the other end of the bearing body, the bearing body is fixedly connected inside the bearing block A with a seat and the bearing block B with a seat, a motor plate is fixedly connected to the side wall of the fuselage frame, a motor is fixedly connected to the side wall of the motor plate, a synchronous wheel A is fixedly connected to the output end of the motor, a transmission assembly is arranged on the outer wall of the synchronous wheel A, and the transmission assembly is used to transmit rotational force.

[0007] Furthermore, the transmission assembly includes a synchronous belt, and the synchronous belt is slidably connected to the outer wall of the synchronous wheel A.

[0008] Furthermore, a synchronous wheel B is rotatably connected inside the synchronous belt, a side wall of the synchronous wheel B is fixedly connected inside the bearing body, and a motor cover is provided on the side wall of the synchronous belt.

[0009] Furthermore, a passive roller is rotatably connected to the other side of the fuselage frame, and passive fixing blocks are arranged on both sides of the passive roller.

[0010] Furthermore, the passive roller and the outer wall of the active roller are slidably connected with a belt.

[0011] Furthermore, the seat bearing block A and the seat bearing block B can be replaced by active adjustment seats.

[0012] Furthermore, the active adjustment seat is fixedly connected to the outer wall of the bearing body, and a top block is provided on the side wall of the active adjustment seat.

[0013] Furthermore, the passive fixing block can be replaced by a passive adjustment seat, and the passive adjustment seat is slidably connected to both ends of the passive roller.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, firstly, the synchronous wheel A is driven to rotate inside the motor cover by the rotational force output by the motor to the synchronous wheel A, and finally the belt on the outer wall of the active roller can slide and drive the passive roller on the other side to rotate inside the passive fixed block. Thus, the bearing and the traction roller can be installed and run concentrically. In the concentric state, the shaft grinding phenomenon between the bearing and the traction roller is not easy to occur, thereby solving the problems of abnormal noise and damage to the traction roller.

[0016] 2. In the utility model, by replacing the bearing block B with an active adjustment seat and the passive fixed block with a passive adjustment seat, the passive roller is allowed to slide inside the passive adjustment seat, so that the shaft system can autonomously adjust the concentricity of the shaft, thereby improving the adjustability of the shaft system and the optimization efficiency of the working scene.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 2 The utility model provides an embodiment: an automatic adjustment device for the concentricity of a rotating shaft, comprising a fuselage frame 1, an active roller 7 is rotatably connected inside the fuselage frame 1, bearing bodies 12 are rotatably connected at both ends of the active roller 7, a bearing block A2 with a seat is arranged at one end of the bearing body 12, a bearing block B11 with a seat is arranged at the other end of the bearing body 12, the bearing body 12 is fixedly connected inside the bearing block A2 with a seat and the bearing block B11 with a seat, a motor plate 13 is fixedly connected to the side wall of the fuselage frame 1, a motor 5 is fixedly connected to the side wall of the motor plate 13, a synchronous wheel A3 is fixedly connected to the output end of the motor 5, a transmission assembly is arranged on the outer wall of the synchronous wheel A3, and the transmission assembly is used to transmit rotational force.

[0024] Specifically, the motor 5 drives the synchronous wheel A3 to start rotating inside the motor cover 14 by outputting a rotating force. The rotation of the synchronous wheel A3 causes the synchronous belt 6 installed on its outer wall to start sliding. At this time, the movement of the synchronous belt 6 is transmitted to the synchronous wheel B4, causing the synchronous wheel B4 to also start rotating. The rotating force of the synchronous wheel B4 is transmitted to the bearing body 12. The bearing body 12 is installed inside the fuselage frame 1 and the seat bearing block B11. Therefore, as the synchronous wheel B4 rotates, the bearing body 12 starts to rotate. The rotation of the bearing body 12 then drives the active roller 7 to start rotating. The outer wall of the active roller 7 is installed with a belt 8. The belt 8 starts to slide with the rotation of the active roller 7, and drives the passive roller 9 on the other side to rotate inside the passive fixed block 10 through a well-designed transmission structure. Such a structural design ensures the concentric running state between the bearing and the traction roller. In the concentric state, the two screws arranged inside the bearing body 12 are locked in the groove inside the traction roller, thereby effectively reducing the occurrence of wear and abnormal noise problems. The load distribution of the bearing is even, local wear is not prone to occur, and the traction roller will not be damaged, thereby extending the service life of the bearing and the traction roller, and significantly reducing the noise and vibration that may occur during operation.

[0025] Reference Figure 3 The transmission assembly includes a synchronous belt 6, which is slidably connected to the outer wall of the synchronous wheel A3, and the synchronous belt 6 is rotatably connected to the synchronous wheel B4 inside. The side wall of the synchronous wheel B4 is fixedly connected to the inside of the bearing body 12, and a motor cover 14 is provided on the side wall of the synchronous belt 6. The other side of the fuselage frame 1 is rotatably connected to the passive roller 9, and passive fixing blocks 10 are provided on both sides of the passive roller 9. The passive roller 9 and the outer wall of the active roller 7 are slidably connected with a belt 8. The bearing block A2 with a seat and the bearing block B11 with a seat can be replaced by an active adjustment seat 15, and the active adjustment seat 15 is fixedly connected to the outer wall of the bearing body 12. The side wall of the active adjustment seat 15 is provided with a top block 17. The passive fixing block 10 can be replaced by a passive adjustment seat 16, and the passive adjustment seat 16 is slidably connected to both ends of the passive roller 9.

[0026] Specifically, after the seat bearing block B11 is replaced by the active adjustment seat 15, and the passive fixing block 10 is replaced by the passive adjustment seat 16, the concentricity of the rotating shaft can be effectively adjusted by the sliding of the passive roller 9 inside the passive adjustment seat 16 and the limiting of the top block 17. This improvement enables the rotating shaft system to have the ability to autonomously adjust the concentricity, thereby significantly improving the adjustability of the system and the efficiency of optimizing the working scene. The design of the active adjustment seat 15 and the passive adjustment seat 16 allows the calibration and adjustment of the centering state of the bearing and the traction roller during actual operation. The sliding action of the passive roller 9 inside the passive adjustment seat 16, combined with the action of the top block 17 of the limiting device, can fine-tune the positional relationship between the bearing and the traction roller to ensure that they maintain an ideal concentric state. This adjustment mechanism is particularly suitable for rotating shaft systems that need to be frequently adjusted or adapted to different workloads, thereby improving the flexibility and adaptability of the system.

[0027] Working principle: When starting this shaft system, first the motor 5 outputs a rotating force to the synchronous wheel A3 to drive the synchronous wheel A3 to rotate inside the motor cover 14. The rotation of the synchronous wheel A3 drives the synchronous belt 6 on its outer wall to start sliding. At this time, the synchronous belt 6 drives the synchronous wheel B4 to rotate as well. The rotation of the synchronous wheel B4 can be transmitted to the bearing body 12 to make it rotate inside the fuselage frame 1 and the bearing block B11 with a seat and drive the active roller 7 to rotate. At this time, the belt 8 on the outer wall of the active roller 7 can slide and drive the passive roller 9 on the other side to rotate inside the passive fixed block 10. This structure realizes the bearing and the traction roller. After installation, the rollers run concentrically, and the two screws arranged inside the bearing body 12 are locked in the groove inside the traction roller, so that the shaft grinding phenomenon between the bearing and the traction roller is not likely to occur in the concentric state, thereby solving the abnormal noise problem, and replacing the bearing block B11 with an active adjustment seat 15, and the passive fixing block 10 with a passive adjustment seat 16. The concentricity of the rotating shaft can be adjusted by sliding the passive roller 9 inside the passive adjustment seat 16 and limiting the top block 17, thereby achieving the effect that the rotating shaft system can autonomously adjust the concentricity of the rotating shaft, thereby improving the adjustability of the rotating shaft system and the efficiency of optimizing the working scene.
