TECHNICAL FIELD
[0001] The application belongs to the technical field of conductive ring manufacturing, and particularly relates to a braided conductive ring. BACKGROUND
[0002] The output shaft of a variable frequency motor generates an induced voltage when the current output by a frequency converter is higher than the action of a variable frequency switch, and the induced voltage is released through the current of the output shaft of the variable frequency motor. In the release process, the voltage will break through the oil film between the bearing balls on the output shaft of the variable frequency motor, thereby causing the bearing seat, bearing balls and track of the bearing to be electrically corroded, so a conductive ring needs to be made. The process difficulty of the conductive ring is mainly concentrated in the fixing of the conductive fiber, because the conductive fiber needs to be fixed radially on the inner circumferential surface of the conductive ring. Since the conductive fiber is relatively small and relatively soft, the process of radially arranging the conductive fiber on the circumferential surface of the conductive ring is very complex, the process difficulty is high, and the production efficiency is low, which is not conducive to technology popularization.

[0019] As Figures 1-3 shown, a braid type conductive ring includes an outer ring shell 1, a winding frame 2, and a conductive fiber 3. The winding frame 2 and the outer ring shell 1 are both circular rings. The outer ring shell 1 and the winding frame 2 are made of conductive material. The winding frame 2 is coaxially located in the outer ring shell 1. The inner circumferential surface of the winding frame 2 is radially provided with a support column 4. The outer surface of the support column 4 is wrapped with a braid woven by the conductive fiber 3.
[0020] In this embodiment, after such design, the braid wrapped around the support column 4 plays a role of conducting electricity. Meanwhile, such design increases the contact surface of the support column 4 with the output shaft of the motor during use, and the conducting effect is better. Compared with the mode that the conductive fiber 3 is radially arranged on the conductive ring, the process difficulty of wrapping the braid woven by the conductive fiber 3 on the support column 4 is smaller, so that the production rate is improved.
[0021] Preferably, the winding frame 2 is provided with a plurality of support columns 4 on the inner circumferential surface, the length of each support column 4 is equal, and the braided fabric is wrapped around each support column. In this way, the contact area between the conductive ring and the output shaft of the motor is larger.
[0022] Preferably, the winding frame 2 is in interference fit with the outer ring shell 1. In this way, the installation of the outer ring shell 1 and the winding frame 2 is more stable, and the winding frame 2 is not easy to fall off the outer ring shell 1.
[0023] Preferably, the distance between any two adjacent support columns 4 on the winding frame 2 is equal. In this way, the overall structure is more beautiful.
[0024] Preferably, the outer ring shell 1 includes a shell bottom 1-1 and a side wall 1-2, the shell bottom 1-1 is a circular ring, the side wall 1-2 surrounds the outer circumferential surface of the shell bottom 1-1, and the outer circumferential surface of the winding frame 2 is in interference fit with the inner circumferential surface of the side wall 1-2. By providing the side wall 1-2, the winding frame 2 is protected.
[0025] Preferably, it further includes an end cover 6, the end cover 6 is annular, the inner diameter of the end cover 6 is equal to the inner diameter of the shell bottom 1-1, the end cover 6 covers the side of the winding frame 2 away from the shell bottom 1-1, and the outer circumferential surface of the end cover 6 is in interference fit with the inner circumferential surface of the side wall 1-2. After providing the end cover 6, the winding frame 2 and the braided fabric are covered, and the protection effect is achieved.
[0026] Preferably, the outer circumferential surface of the winding frame 2 is provided with a plurality of notches 5. In this way, the braided fabric can be bundled on the winding frame 2 by bundling during manufacturing, and at the same time, the rope around the outer circumferential surface of the winding frame 2 passes through the notches 5, so as not to affect the fit between the winding frame 2 and the outer ring shell 1.
[0027] Specifically, each notch 5 corresponds to the gap between two adjacent support columns on the winding frame.
