Description

Technical Field

[0001] This utility model is a double-headed support motor with an I-beam wheel, belonging to the field of motors. Background Technology

[0002] With the development of industrial automation, electric motors are increasingly used in various mechanical equipment, especially in the field of material handling and processing. In these applications, electric motors not only need to provide power, but also need to precisely control the tension and position of materials.

[0003] Traditional single-support motors may experience instability in the I-beam winding process due to the lack of a single support point. This instability can cause fluctuations in material tension, affecting the uniformity and quality of material winding. Furthermore, single-support structures may vibrate under high loads or high speeds, further impacting material processing accuracy and motor lifespan. Therefore, the double-support motor design was developed. By placing support points on both sides, the double-support motor provides more stable and uniform support force. This design significantly reduces vibration and misalignment of the I-beam winding process, thereby improving material winding accuracy and motor operational stability.

[0004] However, existing dual-head support motors still present some design and implementation challenges. For example, how to ensure the synchronization and coordination of the two support points, and how to achieve efficient tension control while maintaining stability. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a double-headed support motor for I-beam wheels, so as to solve the technical problems of poor synchronization and adaptability of existing double-headed support motors.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a double-headed support motor for an I-beam wheel, comprising:

[0007] The base includes a horizontally arranged base plate and vertically arranged mounting bases at the left and right ends;

[0008] A transmission assembly includes a motor fixedly mounted on a base, a pull shaft connected to the output end of the motor, a main and driven shaft sleeved on the outside of the pull shaft, and an I-beam wheel sleeved on the outside of the main and driven shafts.

[0009] A support assembly located inside the mounting base includes a shaft head for clamping the pull shaft and a nut for fastening the connection, the nut being used to fix the relative position between the shaft head and the pull shaft.

[0010] Furthermore, the shaft head includes a first shaft head and a second shaft head. One end of the first shaft head is connected to the output end of the motor, and the other end is provided with a groove. The second shaft head has a through hole inside.

[0011] Furthermore, the mounting base includes a first mounting base and a second mounting base. The motor is fixedly connected to the base via a motor mounting end located on the right side of the first mounting base. One end of the pull shaft is connected to the first shaft head via a groove, and the other end passes through a through hole and is fastened to the second mounting base via a nut.

[0012] Furthermore, each shaft head is equipped with a double-row angular contact bearing, and both ends of the driving and driven shafts are supported on the mounting base by the double-row angular contact bearings.

[0013] Furthermore, the driving shaft passes through the inner hole of the I-beam wheel, and the I-beam wheel is located between the first mounting base and the second mounting base, and is fixed to the middle of the driving shaft by a spline connection.

[0014] Furthermore, the spline connection includes at least two pairs of meshing spline teeth to ensure torque transmission and synchronous rotation between the I-beam and the driving and driven shafts.

[0015] Furthermore, the motor also includes a tension control component, which includes grinding blocks symmetrically arranged on both sides of the I-beam wheel. The grinding blocks are connected to a tension sensor, which can feed back the tension signal to the motor in real time.

[0016] Furthermore, the driving and driven shafts coincide with the central axis of the I-beam wheel.

[0017] Furthermore, the double-row angular contact bearing is an adjustable bearing.

[0018] The beneficial effects of this utility model are:

[0019] The support assembly of this application provides accurate positioning for the motor and pull shaft through the cooperation between the double mounting bases, double shaft heads and nuts. The design of the double-head support structure can effectively reduce the vibration and offset of the motor during operation, improve the stability and reliability of the entire system, and compared with the stress concentration of a single support, it can make the load evenly distributed at both ends of the motor, greatly extending the service life of the motor and related components.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 , Figure 2 As shown, this utility model provides a technical solution for a double-headed support motor for an I-beam wheel, which includes:

[0026] The base 1 includes a horizontally arranged base plate 11 and vertically arranged mounting bases 12 at the left and right ends;

[0027] The transmission assembly 2 includes a motor 21 fixedly mounted on the base 1. The output end of the motor 2 is connected to a pull shaft 22. A main and driven shaft 23 is sleeved on the outside of the pull shaft 22. An I-beam wheel 24 is sleeved on the outside of the main and driven shaft 23.

[0028] The support assembly 3 is located inside the mounting base 12 and includes a shaft head 31 for clamping the pull shaft 22 and a nut 32 for fastening the connection. The nut 32 is used to fix the relative position between the shaft head 31 and the pull shaft 22.

[0029] To improve the stability of the connection between the pull shaft and the shaft head, the shaft head 31 includes a first shaft head 311 and a second shaft head 312. One end of the first shaft head 311 is connected to the output end of the motor 21, and the other end is provided with a groove. The second shaft head 312 has a through hole inside. This design allows the pull shaft 22 to be stably clamped through the groove and the through hole, while also facilitating installation and adjustment.

[0030] To ensure precise alignment of the motor and the pull shaft, the mounting base 12 includes a first mounting base 121 and a second mounting base 122. The motor 21 is fixedly connected to the base 1 via a motor mounting end 13 located on the right side of the first mounting base 121. One end of the pull shaft 22 is connected to the first shaft head 311 via a groove, and the other end passes through a through hole and is fastened to the second mounting base 122 via a nut 32. This structure makes the installation of the motor 21 more stable and ensures the accurate positioning of the pull shaft 22.

[0031] The second mounting base 122 is equipped with a front cover for the main and driven shafts on the right side and a rear cover for the main and driven shafts on the left side. At least a portion of the rear cover of the main and driven shafts that connects to the second shaft head is provided with a K-type locking nut to ensure the stable fixation of the main and driven shafts 23 and prevent the shaft head from loosening due to vibration or external impact during motor operation. This further improves the reliability and durability of the entire motor system. Especially under high load or high speed operating conditions, the cooperation between the K-type locking nut and its opposite nut 32 provides stronger fixing stability, ensuring efficient and safe operation under various working conditions.

[0032] To enhance the support stability of the master and driven shafts, each shaft head 31 is equipped with a double-row angular contact bearing 33. Both ends of the master and driven shaft 23 are supported on the mounting base 12 by the double-row angular contact bearings 33. The double-row angular contact bearings 33 can provide high-precision support to ensure the smooth operation of the master and driven shaft 23.

[0033] To ensure effective connection and torque transmission between the I-beam and the driving shaft, the driving shaft 23 passes through the inner hole of the I-beam 24. The I-beam 24 is located between the first mounting base 121 and the second mounting base 122, and is fixed to the middle of the driving shaft 23 by a spline connection.

[0034] To improve the stability of torque transmission, the spline connection includes at least two pairs of meshing spline teeth to ensure torque transmission and synchronous rotation between the I-beam 24 and the driving and driven shafts 23.

[0035] To achieve precise control of material tension, the motor also includes a tension control component, which includes grinding blocks 25 symmetrically arranged on both sides of the I-beam wheel 24. The grinding blocks 25 are connected to a tension sensor, which can feed back the tension signal to the motor 21 in real time. The introduction of the tension sensor enables the system to monitor and adjust the tension in real time, thereby improving the quality of material winding.

[0036] To ensure the uniformity and stability of material winding, the driving shaft 23 is aligned with the central axis of the I-beam 24. This alignment helps to reduce offset and unevenness during the winding process and improve the winding quality.

[0037] To accommodate different loads, the double-row angular contact bearing 33 is an adjustable bearing, which allows the preload to be adjusted according to actual working conditions, thereby optimizing performance and extending service life.

[0038] Example 1:

[0039] The working principle of this application is as follows:

[0040] When motor 21 starts, it generates torque through its output end. This torque is transmitted to pull shaft 22 via first shaft head 311, which is directly connected to the motor. The torque is then transmitted to driving shaft 23 via pull shaft 22. Driving shaft 23 passes through the inner hole of I-beam 24 and is fixed to I-beam 24 via a spline connection located in the middle of driving shaft 23. At least two pairs of meshing spline teeth ensure torque transmission and synchronous rotation between I-beam 24 and driving shaft 23.

[0041] Once the H-beam 24 receives the torque transmitted from the driving and driven shafts 23, it begins to rotate and wind up the wire. During the winding process, to reduce tension fluctuations in the wire, abrasive blocks 25 located on both sides of the H-beam 24 regulate the pressure of the H-beam 24 via pneumatic cylinders. Tension sensors on the abrasive blocks 25 monitor the wire tension in real time and feed the signal back to the motor 21. Based on the feedback signal, the controller inside the motor adjusts the speed of the motor 21 or the pressure of the abrasive blocks 25 in real time to maintain stable wire tension.

[0042] Example 2:

[0043] The tension adjustment in this application is achieved through closed-loop control between the motor 21, the grinding block 25, and the sensor. The specific steps are as follows:

[0044] During normal operation of motor 21, the tension sensor on grinding block 25 monitors the tension of the wire in real time. The sensor converts the tension data into an electrical signal and sends it to the controller. The controller calculates the required adjustment based on the deviation between the preset tension reference value and the actual tension value. If the actual tension is lower than the reference value, the controller will instruct motor 21 to increase its speed, thereby increasing the rotational speed of the I-beam 24 and the tension of the wire; conversely, if the actual tension is higher than the reference value, the controller will instruct motor 21 to decrease its speed to reduce the tension of the wire.

[0045] When an abnormal situation is detected, such as the tension value fed back by the tension sensor exceeding the preset safety range, the controller will trigger an emergency response mechanism to quickly reduce the speed of the motor 21, or even temporarily stop the motor operation and issue an alarm signal. This emergency response helps to prevent wire breakage or equipment damage, and protects the safety of operators and the normal operation of the equipment.

[0046] Example 3:

[0047] In this application, the key to achieving double-head fastening lies in using two mounting bases (first mounting base 121 and second mounting base 122) and mating shafts (first shaft 311 and second shaft 312) and corresponding fasteners (nut 32 and K-type lock nut).

[0048] First, the motor 21 is fixed to the right side of the first mounting base 121 on the base 1 via the motor mounting end 13. Then, one end of the pull shaft 22 is inserted into the groove of the first shaft head 311, ensuring it is tightly connected to the output end of the motor. Next, the second shaft head 312 is mounted on the second mounting base 122, and the other end of the pull shaft 22 passes through the through hole of the second shaft head 312. The pull shaft 22 is then tightened from the left side of the second mounting base 122 using the nut 32, ensuring the relative position between the pull shaft and the shaft head is fixed. To further enhance the stability, a K-type locking nut is installed at the part where the rear end cover of the main and driven shafts meets the second shaft head. Utilizing the wedge locking principle of the K-type locking nut, a locking force is provided to prevent the main and driven shafts 23 from loosening due to vibration or external impact during motor operation.

[0049] Finally, by adjusting the double-row angular contact bearing 33 to ensure the correct position and preload of the master and driven shafts 23, and then fixing the bearings, the motor is securely installed and the master and driven shafts are precisely fixed, providing a stable foundation for material winding.

[0050] This embodiment demonstrates how the double-headed support motor of this application achieves efficient and stable material winding through double-head fastening. This design not only improves the quality and efficiency of material winding but also extends the service life of the motor, reduces maintenance costs, and brings significant economic and operational benefits to users.
