Description

Technical Field

[0001] This utility model relates to the field of coupling technology, and in particular to a universal encoder coupling. Background Technology

[0002] In automatic control systems, encoders are commonly used counting and control elements. Typically, the encoder input shaft is connected to the output shaft of the equipment via a coupling to ensure synchronous rotation. Encoder couplings are usually rigid structures. However, in practical use, misalignment between the encoder input shaft and the equipment output shaft can occur. This misalignment can lead to the encoder coupling breaking under stress, or even damage to the encoder itself. Utility Model Content

[0003] To address the problems of existing technologies, this utility model provides a universal encoder coupling, comprising:

[0004] Two connecting bushings;

[0005] Two expansion bushings are respectively placed in the holes provided by the connecting bushings through the two open ends of the connecting bushings;

[0006] The universal telescopic assembly is connected between the closed ends of the two connecting bushings.

[0007] Furthermore, the extended bushing, the connecting bushing, and the shaft to be connected are connected by set screws.

[0008] Furthermore, spring dust covers are installed on the two connecting bushings, and the spring dust covers are located between the annular sides on the sidewalls of the open ends of the two connecting bushings.

[0009] Furthermore, the wall thickness of the extended bushing is selected based on the outer diameter of the shaft.

[0010] Furthermore, the universal telescopic assembly includes:

[0011] Two rotating connectors, one end of which is rotatably connected to the closed ends of the two connecting bushings respectively;

[0012] The first connecting shaft and the second connecting shaft are rotatably connected to the other ends of the two rotating connecting bodies, and the first connecting shaft and the second connecting shaft are telescopically slidably connected.

[0013] Furthermore, the closed end of the connecting bushing is connected to two first connecting plates;

[0014] The rotating connector includes a sleeve and a connecting rod. One end of the connecting rod is connected to the side wall of the sleeve. The sleeve is located between two first connecting plates and is rotatably connected to the two first connecting plates by a first pin.

[0015] The other ends of the connecting rods of the two rotating connectors are respectively rotatably connected to the first connecting shaft and the second connecting shaft.

[0016] Furthermore, a through notch is opened at the other end of the connecting rod, dividing the end into two symmetrical cantilever segments;

[0017] Both the first connecting shaft and the second connecting shaft are connected to a second connecting plate at their ends. The second connecting plate is located between the two cantilever sections and is rotatably connected by a second pin.

[0018] Furthermore, the other end of the first connecting shaft is located inside the second connecting shaft and is connected by a spline telescopic sliding connection.

[0019] The beneficial effects of the technical solution provided by this utility model are as follows: the universal encoder coupling includes two connecting bushings and two extension bushings. The two extension bushings are respectively connected to the holes provided in the two connecting bushings. A universal telescopic assembly is connected between the closed ends of the two connecting bushings. The universal encoder coupling can adapt to abnormal situations where the encoder input shaft and the output shaft of the equipment are not concentric.

[0020] Secondly, the wall thickness of the extended bushing is selected according to the outer diameter of the shaft to meet the needs of different shaft diameters and reduce the amount of couplings in stock on site.

[0021] Furthermore, spline couplings of different lengths can be replaced to accommodate the varying distances required by encoders and equipment.

[0022] In addition, spring dust covers are installed on the two connecting bushings to protect the coupling and extend its service life. Attached Figure Description

[0033] See Figures 1-5 A universal encoder coupling includes: a coupling assembly, a universal telescopic assembly, and a spring dust cover.

[0034] The coupling assembly includes two connecting bushings 1 and two extending bushings 2. The connecting bushing 1 is a hollow cylinder with an open end and a closed end. The closed end of the connecting bushing 1 is connected to two first connecting plates 9. The two extending bushings 2 are respectively placed in the holes of the two connecting bushings 1, and connecting holes are opened on the side walls of both the connecting bushing 1 and the extending bushing 2. The extending bushing 2, the connecting bushing 1 and the shaft to be connected are connected by a set screw 3. The wall thickness of the extending bushing 2 is selected according to the outer diameter of the shaft to meet the needs of different shaft diameters and reduce the amount of couplings in stock on site.

[0035] The universal telescopic assembly includes two rotating connecting bodies 6, a first connecting shaft 7, and a second connecting shaft 8. The rotating connecting body 6 includes a sleeve 10 and a connecting rod 11. One end of the connecting rod 11 is connected to the side wall of the sleeve 10, and the other end of the connecting rod 11 has a through notch, dividing the end into two symmetrical cantilever segments 15. Each of the two symmetrical cantilever segments 15 has a connecting hole. The ends of the first connecting shaft 7 and the second connecting shaft 8 are both connected to a second connecting plate 13, which also has a connecting hole.

[0036] During connection, the sleeve 10 of the rotating connecting body 6 is located between the two first connecting plates 9 of the connecting shaft sleeve 1. The first connecting plate 9 has a connecting hole. The first pin 12 passes through the connecting hole of the first connecting plate 9 and the sleeve 10, rotatably connecting the rotating connecting body 6 to the connecting shaft sleeve 1. The second connecting plates 13 of the first connecting shaft 7 and the second connecting shaft 8 are located between the cantilever sections 15 of the two connecting rods 11, respectively. The second pin 14 passes through the connecting hole of the second pin 12 and the connecting hole of the second connecting plate 13, rotatably connecting the first connecting shaft 7 and the second connecting shaft 8 to the two connecting rods 11.

[0037] The end of the second connecting shaft 8 furthest from the second connecting plate 13 has an opening and is hollow inside. The end of the first connecting shaft 7 furthest from the second connecting plate 13 is located inside the second connecting shaft 8 and is telescopically connected via a spline. Spline couplings of different lengths can be replaced to accommodate different distance requirements of encoders and equipment.

[0038] Annular sidewalls 5 are connected to the sidewalls of the open ends of the two connecting bushings 1. Spring dust covers 4 are installed on the two connecting bushings 1. The spring dust covers 4 are fixed between the two annular sidewalls 5. The spring dust covers provide protection for the coupling and improve its service life.

[0039] In use, the encoder input shaft and the power output shaft of the installed encoder equipment are located on two extension bushings 2, and the three are fixed together by set screws 3. This universal encoder coupling can accommodate abnormal situations where the encoder input shaft and the output shaft of the equipment are not concentric.
