Description

Technical Field

[0001] The utility model relates to the field of reducer flange shaft connection structures, in particular to a reducer flange shaft connection structure. Background Art

[0002] The reducer flange shaft is an important component in the mechanical transmission system. It is mainly used to connect the reducer and load equipment (such as motors, pumps, conveyor belts, etc.) to achieve torque transmission and speed regulation.

[0003] For example, Chinese patent CN211423192U discloses a precision planetary reducer flange shaft connection structure. This patent aims to solve the problem that the flange seat of the existing planetary gear reducer is mainly assembled through the flange at the end during assembly and application, and lacks a structural side installation structure, making it inconvenient to assemble and strengthen support and difficult to improve stability.

[0004] The solution of the above patent is: by setting four mounting support plates on the side surface of the bearing seat mounting frame, and opening mounting through holes on the plate surface of the mounting support plates, the overall structure is easy to assemble with the external structure through the mounting support plates; and by setting an assembly right-angle plate frame with mounting circular holes and fixing it on the end face of the flange, the assembly right-angle plate frame is connected to the external structure to provide lateral support to the flange, thereby providing a lateral support installation structure.

[0005] However, although the above patent introduces a side mounting structure, it lacks additional locking and anti-loosening design, which makes the device prone to displacement or loosening in a high-vibration environment, because it mainly relies on the end flange and the mounting support plate to fix the entire device. For this reason, a reducer flange shaft connection structure is designed. Utility Model Content

Locking rods 4 are staggered on both sides of the output end of the reducer 1. A limiting groove is provided in the flange 3 on the output end. The limiting groove rotates with a number of locking rods 4 and forms a lock, realizing the locking function of the output end of the reducer 1 to prevent relative rotation during operation. The output end and the input end of the reducer 1 are circumferentially provided with a number of assembly parts 6. Both sides of the upper part of the assembly part 6 are provided with a bent The limit block 7 is provided, and a cover plate 8 is provided at the center of the top of the assembly part 6 for sliding and rotating. The two ends of the cover plate 8 are designed to protrude, and the protruding part is against the lower part of the limit block 7. A spring 9 is provided at the lower part of the assembly part 6. A wedge rod 10 is provided to slide through the upper part of the assembly part 6. The lower part of each wedge rod 10 slides in the corresponding output end or input end. The upper end of the wedge rod 10 is connected to the bottom of the cover plate 8. The spring 9 surrounds the upper part of the wedge rod 10, and the bottom end of the spring 9 is connected to the upper end of the wedge-shaped part of the wedge rod 10. The spring 9 provides a restoring force so that the wedge rod 10 can slide up and down during operation, and through The cover plate 8 is rotated to achieve a locked or unlocked state, thereby ensuring the safety and reliability of the connection. A tapered rod 11 is commonly inserted between the two flanges 3 and the corresponding output end or input end. The tapered portion of the tapered rod 11 is inserted into the corresponding output end or input end. The end of each tapered rod 11 is provided with a groove corresponding to the wedge-shaped portion of the wedge-shaped rod 10, and the two are abutted to ensure a good bite effect. The end of each tapered rod 11 extends outward and passes through the corresponding flange 3, and the end of the protruding portion is provided with a torsion piece, and the end of the torsion piece abuts against the corresponding end of the flange 3.

[0024] like Figure 4-Figure 5 As shown, it also includes a wedge washer 12 and a wedge washer 2 13. The outer side of the protruding part of each tapered rod 11 is rotatably sleeved with a wedge washer 12 and a wedge washer 2 13 that are engaged with each other, and each wedge washer 12 and wedge washer 2 13 are located between the corresponding flange 3 and the end of the torsion piece, so as to achieve stability; both ends of the wedge washer 12 and the wedge washer 2 13 are provided with a plurality of circumferentially and equidistant helical teeth, and the helical teeth of the two are matched, which enhances the anti-loosening performance of the connection part, especially in a high vibration environment, and can effectively prevent the connection from loosening.

[0025] like Figure 2 As shown, a sealing ring 5 is also included. A sealing ring 5 is embedded in the outer side of the output end and the input end of the reducer 1 to enhance the sealing. The sealing ring 5 is used to enhance the sealing of the output end and the input end of the reducer 1 to prevent lubricating oil leakage or external impurities from entering.

[0026] like Figure 1 As shown, a rubber sleeve 14 is also included. The outer surfaces of the assembly parts 6 at the output end and the input end of the reducer 1 are covered with a protective rubber sleeve 14 to protect the internal parts from the influence of the external environment.

[0027] like Figure 1 As shown, auxiliary parts 15 are also included. Several auxiliary parts 15 for providing stability are circumferentially arranged on the outside of the joints between the flange 3 and the corresponding output end or input end. The auxiliary parts 15 increase the stability of the joints between the flange 3 and the end of the reducer 1, thereby improving the strength of the entire connection structure.

[0028] During installation, first align the reducer 1 and motor 2 to ensure the subsequent accurate docking of the output shaft of motor 2 and the input end of reducer 1. Before installing the flange 3, first rotate the cover 8 90 degrees so that the cover 8 no longer presses against the limit block 7. At this time, the spring 9 will drive the wedge rod 10 to slide up under the action of the restoring force. After completion, rotate the cover 8 back to its original position again so that the cover 8 relies on the restoring force of the spring 9 to press against the upper part of the limit piece to provide space for subsequent operations. Then fix the flange 3 on the installation place of the motor 2 and the input end of the reducer 1, and on the output end of the reducer 1 respectively, gently rotate the flange 3 so that the limit groove on it is aligned with the locking rod 4, and slides smoothly into the limit groove to form a preliminary lock, and then insert the tapered rod 11 between the corresponding flange 3 and the output end or input end, and rotate the cover 8 again. 90 degrees, and press the wedge rod 10 by hand to make it return to the output end or input end and contact the notch of the tapered rod 11, and rotate the cover plate 8 back to its original position again so that the protruding parts at both ends are against the lower part of the limit block 7 to complete the final locking, preventing the wedge rod 10 from popping out accidentally, and further enhancing the reliability of the connection. In addition, it is necessary to put the wedge washer 12 on the outside of the protruding part of the tapered rod 11, and then put on the wedge washer 2 13 to ensure that the helical teeth of the two match each other. The mutual engagement of the wedge washer 12 and the wedge washer 2 13 further enhances the stability and anti-loosening function of the connection. Even in a high vibration environment, the stability of the connection can be maintained to prevent loosening. Finally, a rubber sleeve 14 is put on the outside of the assembly part 6 to provide additional protection to prevent the influence of the external environment.
