DETAILED DESCRIPTION

[0017] The utility model will be further described in detail in combination with the drawings.

[0018] Wherein, same parts are indicated by same reference numerals. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a particular component.

[0019] As shown in the figure, a transmission flange of a high-stability speed reducer includes a first flange shaft sleeve 1 and a second flange shaft sleeve 2. The circumferential surface of the first flange shaft sleeve 1 is provided with a plurality of positioning grooves 3, which are evenly distributed along the circumferential direction of the first flange shaft sleeve 1. The end surface of the second flange shaft sleeve 2 is provided with a plurality of positioning plates 4 inserted into the positioning grooves 3. The end portion of the positioning plate 4 is provided with a clamping portion 5 clamped to the other surface of the first flange shaft sleeve 1.

[0020] When fixing the first flange bushing 1 and the second flange bushing 2, the positioning plate 4 is inserted into the positioning groove 3 and is snapped onto the other end face of the first flange bushing 1 by the snap-fit ​​part 5, thereby completely fixing the two flange bushings, ensuring the stable connection of the two flange bushings, and preventing them from falling off due to the falling of bolts and nuts after long-term use.

[0021] The bottom of the positioning groove 3 is provided with a screw hole 6, and the positioning plate 4 is provided with a through hole 7 corresponding to the screw hole 6. A bolt is provided in the through hole 7 and threaded into the screw hole 6. After the first flange bushing 1 and the second flange bushing 2 are connected, the bolt is used to further improve the stability of the connection between the two flange bushings.

[0022] The first flange bushing 1 has a first external thread 8 on its circumferential surface and a second external thread 9 on its outer surface. It also includes a connecting sleeve 10 fitted onto the circumferential surface of the first flange bushing 1. The inner circumferential wall of the connecting sleeve 10 has an internal thread (not shown in the figure). The first external thread 8 and the second external thread 9 form an external thread that matches the internal thread. A groove 11 for the bolt head to be embedded is provided at the top of the through groove. Thus, when the connecting sleeve 10 is rotated and fitted onto the surface of the first flange bushing 1, the connection stability of the two is further improved, while the bolt can be prevented from falling off.

[0023] The upper surface of the end of the positioning plate 4 is provided with an abutting part 12 that abuts against the connecting sleeve 10. When the connecting sleeve 10 is rotated, it is finally pressed against the abutting part 12, and the two are fixedly connected by bolts, adhesive or other fixing methods, thereby further improving the stability of the connection between the two flange bushings.

[0024] The end of the positioning groove 3 facing the second flange bushing 2 is provided with a first inclined surface 13, and the bottom of the snap-fit ​​part 5 is provided with a second inclined surface 14 parallel to the first inclined surface 13. When the positioning plate 4 is inserted into the positioning groove 3, the first inclined surface 13 abuts against the second inclined surface 14. Under its action, the positioning plate 4 is deformed and tilted outward. When the positioning plate 4 is fully inserted into the positioning groove 3, the positioning plate 4 is reset and the snap-fit ​​part 5 is snapped into the end surface of the first flange bushing 1.

[0025] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
