[0030] 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.

[0031] Example 1

[0032] Figure 1 This is a schematic diagram of the overall structure of a single-head support motor for an I-beam wheel according to this utility model. Figure 2 This is a partial schematic diagram of a single-head support motor for an I-beam wheel according to the present invention. Figure One ,like Figure 1 and Figure 2 As shown, the structure of a single-head support motor of the I-beam wheel according to an embodiment of the present utility model will be described in detail. The structure includes a support base 1, a motor 2 fixedly mounted on one side, and an I-beam wheel 3 coaxially corresponding to the motor 2 on the other side.

[0033] The motor 2 is rotatably provided with a rotating shaft 40. One end of the rotating shaft 40 is rotatably provided inside the motor 2, and the other end passes through the support seat 1 and extends into the I-beam wheel 3 on the other side and is provided with a shaft head 41. A bearing 42 and a fixing member 43 sleeved on the outer wall of the rotating shaft 40 away from the motor 2 are movably provided on the outer wall of the bearing 42 for fixing the bearing 42 and the rotating shaft 40.

[0034] The I-beam wheel 3 has an inner cavity that accommodates the shaft head 41, bearing 42 and fixing member 43. The inner cavity is arranged symmetrically front and back. The shaft head 41, bearing 42 and fixing member 43 are all located in the inner cavity on the rear side, that is, in the inner cavity near the support seat. The inner cavity is also provided with a locking bolt 31, and is connected to the rotating shaft 40 through the locking bolt 31.

[0035] It is to be known that in the embodiment, the direction from the front side to the rear side of the I-shaped wheel 3 to the motor 2 is defined, that is, the I-shaped wheel 3 is located at the front side of the support seat 1, and the motor 2 is located at the rear side of the support seat 1. The support seat 1 is not a traditional distal end bearing seat, which provides a bending moment resisting fulcrum for the motor housing, cooperates with the I-shaped wheel 3, and enhances the ability of the entire motor unit to resist the overturning moment generated by the cantilever load of the winding roller. This design optimizes the system rigidity and stability of the traditional double support structure while retaining the compactness of the single support structure, ensuring stable operation under high-speed heavy load conditions.

[0036] Please refer to Figure 1 , the support seat 1 comprises a support side plate 14 and a support bottom plate 15 arranged perpendicular to each other. Specifically, the support bottom plate 15 is arranged horizontally, and the support side plate 14 is arranged vertically on the support bottom plate 15, and the two are in a perpendicular state. The support bottom plate 15 at the bottom provides stable support force for the support side plate 14 and each component arranged on the support bottom plate 15. The center of the support side plate 14 corresponding to the rotating shaft 40 is provided with a receiving groove 11, which has a depth extending horizontally to the rear side, which can exactly accommodate the fixing member 43. The center of the receiving groove 11 is provided with a rotating hole 12, which communicates on both sides of the support side plate 14. The hole diameter of the rotating hole 12 is matched with the rotating shaft 40, so that the rotating shaft 40 can pass through the rotating hole 12.

[0037] Please refer to Figure 1 , the support side plate 14 is provided with a plurality of fastening bolts 13, and the plurality of fastening bolts 13 are arranged outside the receiving groove 11. Because the motor 2 is arranged at the rear side of the support side plate 14, the fastening bolts 13 are installed and fixed from the left side to the right side of the support side plate 14, so that the motor 2 and the support side plate 14 can be tightly fixed. By fixing and installing through the bolts, the installation steps are reduced, the debugging time is shortened, and the maintenance cost is reduced.

[0038] Please refer to Figure 2The fixing part 43 comprises a cylinder sleeve 431 sleeved on the outer wall of the bearing 42, and a gland 432 is fixedly arranged on the side end face away from the support side plate 14 of the cylinder sleeve 431, that is, the gland 432 is located on the front side of the cylinder sleeve 431 and cooperates with the bearing 42 to prevent the bearing 42 from deviating in the motor. The inner wall of the gland 432 and the outer wall of the rotating shaft 40 are further fixed by arranging a locking nut 433, so that the bearing 42 runs more stably inside. In this embodiment, the locking nut 433 is preferably an F-shaped locking nut, which has excellent corrosion resistance and fatigue resistance, so that the nut is more firm when fastened, effectively preventing loosening caused by vibration. Even in a long-term operating environment, it can also maintain a long service life. In order to prevent leakage of lubricating oil, the rear side of the locking nut 433 is also provided with an oil seal 434, so that the motor can maintain a relatively sealed state when it is running or not running.

[0039] Please refer to Figures 2-3 The cylinder sleeve 431 is adapted to the accommodating groove 11, that is, the cylinder sleeve 431 can be installed in the accommodating groove 11, and the side of the cylinder sleeve 431 close to the support side plate 14 is fixed with the support side plate 14 in the support seat 1 by arranging a plurality of first bolts 435, and the other side of the cylinder sleeve 431 axially corresponding is also provided with a first bolt 435 and a gland 432 for fixation.

[0040] Please refer to Figure 1 In this embodiment, the shaft head 41 is installed at the front end of the rotating shaft 40, and a plurality of first bolts 435 are also arranged between the shaft head 41 and the rotating shaft 40 to fix the shaft head 41 and the rotating shaft 40, so that the bearing 42 and the rotating shaft 40 run more stably in the motor.

[0041] Please refer to Figure 2 The bearing 42 comprises at least one double-row angular contact bearing, and in this embodiment, two double-row angular contact bearings are specifically preferred and arranged side by side in front and back. The double-row angular contact bearing itself can bear a large radial and axial load, and after two double-row angular contact bearings are arranged side by side, the overall load capacity is further enhanced, which can better cope with the large load generated during the operation of the winding motor and effectively improve the stability and reliability of the equipment.

[0042] Please refer to Figures 1-2The I-shaped wheel 3, the shaft head 41 and the rotating shaft 40 are kept in line along the axis, ensuring the stability of the motor during operation, the axial alignment design significantly reduces the vibration and noise of the motor due to eccentricity, and improves the winding accuracy and quality, and the motor body is precisely positioned and fixed by the support seat arranged on one side, and all intermediate links such as the shaft coupling and the additional bearing seat are omitted in the entire power transmission path, thereby fundamentally eliminating the concentricity deviation problem caused by the cumulative installation error of multiple components, wherein the locking bolt 31 is an internal hexagonal bolt, which is sequentially arranged along the axis of the I-shaped wheel 3 and the shaft head 41, and is fixed to the front end of the rotating shaft 40, this design facilitates installation and disassembly in space-limited occasions, provides uniform locking force, ensures the close connection of the I-shaped wheel 3 and the shaft head 41, prevents the parts from loosening under high-speed operation or complex working conditions, and guarantees the stability and reliability of the entire winding device, and is particularly suitable for high-speed winding and small-sized equipment, and improves the applicability and durability of the motor in industrial winding applications.
