Description

Technical Field

[0001] This utility model relates to the field of permanent magnet motor technology, specifically a connecting device for a permanent magnet motor. Background Technology

[0002] Permanent magnet synchronous motors use permanent magnets for excitation, which simplifies the motor structure, reduces processing and assembly costs, and eliminates the need for slip rings and brushes, which are prone to problems, thus improving the reliability of motor operation. Furthermore, since no excitation current is required, there is no excitation loss, which improves the efficiency and power density of the motor. The connection device of the permanent magnet motor is a key part to ensure reliable connection between the motor and the load, power supply, or other mechanical components. When connecting the permanent magnet motor to mechanical components, a flange and bolt connection method is used, whereby the flange on the rotating shaft of the permanent magnet motor is connected to the flange on the mechanical component by bolts.

[0003] However, when connecting a permanent magnet motor to a mechanical component, the threaded holes on the flange of the permanent magnet motor must be aligned with the threaded holes on the flange of the mechanical component before bolts are passed through the threaded holes on the flange of the permanent magnet motor and the mechanical component. This completes the connection between the permanent magnet motor and the mechanical component. However, due to the smooth surface of the flanges, when workers use bolts to connect two flanges, it is very easy for adjacent flanges to slip, causing misalignment of the threaded holes on the two flanges. This makes it inconvenient to align the threaded holes on the two flanges. Furthermore, with the continuous increase in the usage time of the permanent magnet motor, the vibration generated by the permanent magnet motor during use can easily drive the bolts to move, causing the bolts to loosen in the threaded holes, thus affecting the tightness of the connection between the two flanges.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 3 and Figure 8A connecting device for a permanent magnet motor includes a motor body 1. A rotating shaft 2 is fixedly installed on the left side of the motor body 1, connecting the motor body 1 to a first flange 3. The end of the rotating shaft 2 away from the motor body 1 is fixedly connected to the first flange 3. The first flange 3 is connected to a second flange 5 via fastening bolts 4. The fastening bolts 4 connect the first flange 3 and the second flange 5. The second flange 5 is connected to an external mechanical component. By changing the connection method of the first flange 3 or the second flange 5 via the fastening bolts 4, the first flange 3 and the second flange 5 can be separated or connected. A lower clamp 6 is movably installed at the lower end of the first flange 3 and the second flange 5. The upper end of the lower clamp 6 is connected to an upper clamp 7 via spring clips 12 on the front and rear sides. Installed on the upper ends of flange 3 and flange 5, spring clip 12 connects upper clamp 7 and lower clamp 6, thus installing upper clamp 7 and lower clamp 6 at the connection between flange 3 and flange 5. A housing 8 is fixedly installed on both lower clamp 6 and upper clamp 7. A first baffle 9 located to the left of flange 5 is movably connected to the lower left side of housing 8, limiting the position of flange 5. A second baffle 10 located to the right of flange 3 is movably connected to the lower right side of housing 8, limiting the position of flange 3. An active component 11 is provided inside housing 8 for adjusting the horizontal position of baffles 9 and 10.

[0025] Positioning grooves 13 are respectively provided at the upper and lower ends of the left side of flange 3, and protrusions 14 located on the right side of flange 5 are respectively fixedly installed at the front and rear ends of the left side of flange 3.

[0026] Please see Figure 2 , Figure 4 and Figure 5 Positioning blocks 15 are fixedly installed at the upper and lower ends of the right side of the fastening bolt 4, and the outer wall of the positioning block 15 is movably engaged with the inner wall of the positioning groove 13. Grooves 16 are respectively opened at the front and rear ends of the right side of the fastening bolt 4, and the inner wall of the groove 16 is movably engaged with the outer wall of the protrusion 14. The positioning block 15 is engaged with the positioning groove 13, and the groove 16 is engaged with the protrusion 14, which restricts the installation position of flange 3 and flange 5 and prevents flange 3 and flange 5 from slipping against each other before installation.

[0027] The lower clamp 6 has locking blocks 17 fixedly installed on its front and rear sides respectively, and the inner wall of the outer side of the locking block 17 is movably engaged with the outer wall of the spring buckle 12. The middle of the locking block 17 is movably sleeved with a fixing rod 18, which provides a platform for the installation of the spring buckle 12. The spring in the spring buckle 12 is installed inside the fixing rod 18. The upper end of the fixing rod 18 is fixedly installed with a support plate 19. The support plate 19 is set to connect the fixing rod 18 and the upper clamp 7, and the inner end of the support plate 19 is fixedly connected to the outer wall of the upper clamp 7.

[0028] Please see Figure 6 and Figure 7 The movable component 11 includes a spur gear 111, a first ruler strip 112, and a second ruler strip 113. The front side of the spur gear 111 meshes with the rear teeth of the first ruler strip 112. This meshing connection allows the spur gear 111 to rotate circumferentially while simultaneously driving the first ruler strip 112 and the second ruler strip 113 to move horizontally. The movement of the first ruler strip 112 and the second ruler strip 113 respectively drives the first baffle 9 and the second baffle 10 to move in the same direction. The inner end of the first ruler strip 112 is fixedly connected to the outer end of the first baffle 9. The rear side of the spur gear 111 meshes with the front teeth of the second ruler strip 113. The inner end of 3 is fixedly connected to the outer end of the second baffle 10. The outer sides of the first ruler strip 112 and the second ruler strip 113 are respectively fixedly installed with sliding rods 20, and the outer wall of the sliding rod 20 is slidably connected to the inner wall of the outer shell 8. The inner wall of the spur gear 111 is fixedly sleeved with a rotating rod 21, and the upper and lower ends of the rotating rod 21 are respectively movably sleeved with the inner walls of the upper and lower sides of the outer shell 8. The rotating rod 21 provides power for the rotation of the spur gear 111. The upper end of the rotating rod 21 is fixedly installed with a knob 22 located outside the outer shell 8. The outer wall of the rotating rod 21 is fixedly sleeved with a limiting component 23 located inside the knob 22. The limiting component 23 restricts the movement state of the rotating rod 21.

[0029] The limiting component 23 includes a limiting gear 231 and a triangular locking block 232. The left side of the triangular locking block 232 is engaged between two teeth on the right side of the limiting gear 231. When the triangular locking block 232 is engaged with the limiting gear 231, the rotating rod 21 cannot rotate. When the triangular locking block 232 is separated from the limiting gear 231, the rotating rod 21 can rotate. A threaded rod 24 is movably connected to the right side of the triangular locking block 232. A mounting plate 25 is threaded onto the outer wall of the threaded rod 24, and the inner end of the mounting plate 25 is fixedly connected to the outer wall of the outer casing 8.

[0030] Working principle: In use, first, insert the protrusion 14 into the groove 16. At this time, the positioning block 15 is inserted into the positioning slot 13, which can limit the connection between flange 3 and flange 5. Then, use the fastening bolts 4 to fasten flange 3 and flange 5. Next, install the lower clamp 6 below flange 3 and flange 5, press the spring clip 12 to move it into the fixing rod 18, and install the upper clamp 7 on top of flange 3 and flange 5. Next, insert the fixing rod 18 into the locking block 17. As the fixing rod 18 moves downwards within the locking block 17, the spring in the spring clip 12 returns to the outside of the locking block 17, thus connecting the spring clip 12 to the fixing rod 18 and the locking block 17, achieving the connection between the upper clamp 7 and the lower clamp 6. Finally, hold the knob 22 and rotate the rotating rod 21. The rotation of the rotating rod 21 simultaneously drives the rotation of the spur gear 111. Since the spur gear 111 is connected to both the first ruler strip 112 and the second ruler strip 112... When the teeth of ruler strip 113 mesh, the spur gear 111 rotates in a circular motion, driving the horizontal movement of ruler strips 112 and 113. The movement of ruler strips 112 and 113 respectively drives the movement of baffles 9 and 10 in the same direction, until the right side of baffle 9 is tightly against the left side of flange 5, and the left side of baffle 10 is tightly against the right side of flange 3. At this point, the rotation of knob 22 can be stopped. Then, by rotating the threaded rod 24, the threaded rod... The threaded connection between the threaded rod 24 and the mounting plate 25 allows the threaded rod 24 to rotate circumferentially while also moving horizontally. As the threaded rod 24 moves, it drives the triangular locking block 232 to engage between two adjacent teeth of the limiting gear 231, thereby limiting the movement of the movable component 11. This, in turn, limits the first flange 3 and the second flange 5 to the first flange 9 and the second flange 10, thus improving the tightness of the first flange 9 and the second flange 10 on the first flange 3 and the second flange 5.
