Description

Technical Field

[0001] This utility model relates to the field of magneto equipment technology, and in particular to a magneto that is easy to install on magnet tiles. Background Technology

[0002] A magneto typically includes a rotor housing. One end of the rotor housing has a rotor mounting slot for accommodating the magnets and stator, while the other end is the mounting end. The method of fixing the permanent magnets inside the rotor housing is one of the key factors affecting rotor performance. In the existing technology, the magnets are mostly fixed by adhesive bonding, that is, the magnets are directly pasted to the inner wall of the rotor mounting slot using adhesive. This adhesive bonding method has many inherent defects: First, when the rotor rotates at high speed, the adhesive is prone to fatigue failure, causing the magnets to fall off; second, the adhesive bonding method has high requirements for the working environment and personnel operation, and it is difficult to ensure the stable and accurate circumferential distribution uniformity and axial position accuracy of multiple magnets, which directly affects the performance of the magneto. Therefore, there is an urgent need in this field for a magneto that improves assembly accuracy and efficiency and facilitates the installation of magnet tiles. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a magneto motor that improves assembly accuracy and efficiency and facilitates the installation of magnet tiles.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A magneto motor for easy installation of magnetic tiles includes a rotor housing. One axial end of the rotor housing has a rotor mounting groove, and the opposite end is a mounting end. A retainer and a magnetic tile are disposed in the rotor mounting groove. The outer side wall of the retainer abuts against the inner side wall of the rotor mounting groove. The retainer includes a connecting ring and a plurality of supports distributed circumferentially along the connecting ring. The supports extend axially along the connecting ring, and their distal ends have support portions arranged parallel to the connecting ring. An installation cavity for inserting a magnetic tile is formed between two adjacent supports.

[0005] The working principle and advantages of this technical solution for a magneto that is easy to install on magnetic tiles are as follows: During assembly, the magnetic tiles are placed one by one into the convex mounting cavity formed by two adjacent supports on the cage. The cage provides precise positioning of the magnetic tiles from all directions. The outer wall of the cage is in close contact with the inner wall of the rotor mounting slot, achieving initial positioning of the entire cage within the rotor housing. The two opposite sidewalls of the magnetic tiles are constrained between two adjacent supports, which laterally constrain the magnetic tiles, achieving radial and circumferential positioning. One end face of the magnetic tile contacts the inner side of the connecting ring, while its opposite end face contacts the support portion at the far end of the support. The magnetic tiles are positioned from both ends by the connecting ring and the support portion. The magnet is clamped to achieve axial positioning. After the cage and magnet are installed on the rotor housing, adhesive is applied to firmly connect the cage, magnet, and rotor housing together. The mounting cavity of the cage guides and limits the magnet, making the installation operation simple and intuitive. It can ensure that all magnets are evenly distributed circumferentially and have consistent axial position without complicated tooling, thus improving production efficiency and product consistency. The cage provides mechanical support for the magnet, effectively resisting centrifugal force and vibration under high-speed rotation, reducing the risk of magnet detachment, and improving the operational reliability and service life of the magneto.

[0006] Furthermore, the cross-section of the support column is triangular, which includes two contact slopes, and the side edge of the magnetic tile that contacts the contact slope is provided with a chamfer.

[0007] Furthermore, an annular groove is provided on the bottom side of the rotor mounting groove for the support to be embedded.

[0008] Furthermore, the connecting ring has a hollow hole corresponding to the support column.

[0009] Furthermore, the connecting ring, the pillar, and the support are integrally formed.

[0010] Furthermore, a central hole is provided at the center of the mounting end, and a connecting plate is detachably connected to the central hole; the mounting end is provided with multiple connecting through holes that connect it to the rotor mounting slot, and the connecting plate is provided with multiple connecting screw holes that correspond one-to-one with the connecting through holes, and the connecting bolts pass through the connecting through holes and are threadedly connected to the connecting screw holes.

[0011] Furthermore, the mounting end is provided with a plurality of first positioning holes that connect it to the rotor mounting slot, and the connecting plate is provided with a plurality of second positioning holes that correspond one-to-one with the first positioning holes, and a positioning post passing through the second positioning hole is fixedly connected in the first positioning hole.

[0014] Refer to together Figures 1 to 7This embodiment provides a magneto that facilitates the installation of the magnet tile 300, including a rotor housing 100. One axial end of the rotor housing 100 has a rotor mounting groove 101, and the other end is a mounting end 102. A retainer 400 and a magnet tile 300 are disposed in the rotor mounting groove 101. The outer side wall of the retainer 400 abuts against the inner side wall of the rotor mounting groove 101. The retainer 400 includes a connecting ring 410 and a plurality of supports 420 distributed circumferentially along the connecting ring 410. The supports 420 extend axially along the connecting ring 410, and their distal ends have a support portion 430 arranged parallel to the connecting ring 410. An installation cavity 401 for the magnet tile 300 to be installed is formed between two adjacent supports 420.

[0015] In this embodiment, during assembly, the magnetic tiles 300 are placed one by one into the convex mounting cavity 401 formed by two adjacent pillars 420 on the retainer 400. The retainer 400 provides precise positioning of the magnetic tiles 300 in all directions. The outer wall of the retainer 400 is in close contact with the inner wall of the rotor mounting groove 101, achieving initial positioning of the entire retainer 400 within the rotor housing 100. The two opposite sidewalls of the magnetic tiles 300 are confined between the two adjacent pillars 420, which laterally constrain the magnetic tiles 300, achieving radial and circumferential positioning. One end face of the magnetic tile 300 contacts the inner side of the connecting ring 410, while its opposite end face contacts the support portion 430 at the distal end of the pillar 420. The connecting ring 410 and the support portion 430 provide precise positioning of the magnetic tiles 300 in all directions. The retainer 400 clamps the magnet 300 from both the top and bottom ends to achieve axial positioning of the magnet 300. After the retainer 400 and the magnet 300 are installed on the rotor housing 100, adhesive is applied to firmly connect the retainer 400, the magnet 300 and the rotor housing 100 together. The mounting cavity 401 of the retainer 400 guides and limits the magnet 300, making the installation of the magnet 300 simple and intuitive. It can ensure that all magnets 300 are evenly distributed circumferentially and have consistent axial positions without complicated tooling, thus improving production efficiency and product consistency. The retainer 400 provides mechanical support for the magnet 300, which can effectively resist centrifugal force and vibration under high-speed rotation, reduce the risk of magnets 300 falling off, and improve the operational reliability and service life of the magneto.

[0016] Preferably, such as Figure 2 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7As shown, the cross-section of the support column 420 is triangular, including two contact slopes 421. The side edge of the magnetic tile 300 that contacts the contact slopes 421 has a chamfer 310. When the operator places the magnetic tile 300 into the mounting cavity 401 between two adjacent supports 420, the chamfer 310 on the side edge of the magnetic tile 300 contacts the triangular contact slopes 421 of the support column 420. The contact slopes 421 of the support column 420 and the chamfer 310 of the magnetic tile 300 form a guiding structure. With the cooperation of the contact slopes 421 and the chamfer 310, the magnetic tile 300 can more easily... Smoothly sliding into the mounting cavity 401 avoids rigid collisions or jamming between the right edges of the magnetic tile 300 and the surface of the support column 420, making the installation operation smoother and less labor-intensive, and further improving assembly efficiency. After the magnetic tile 300 is installed in place, its two side walls contact the contact slope 421 of the support column 420, increasing the contact area between the support column 420 and the side walls of the magnetic tile 300, improving the reliability of the limit, and providing a larger bonding area for the adhesive to be applied later, thereby improving the overall strength of the rotor housing 100, the magnetic tile 300 and the cage 400.

[0017] Preferably, such as Figure 2 as well as Figure 3 As shown, the rotor mounting slot 101 has an annular groove 130 on its inner bottom side for the support parts 430 to be embedded in. During assembly, the operator places the retainer 400 axially into the rotor mounting slot 101. When the retainer 400 is in place, all the support parts 430 on it will fall into the annular groove 130. The sidewall of the annular groove 130 provides radial restraint for the support parts 430, while the inner bottom side of the annular groove 130 contacts the lower end face of the support parts 430, thus providing an axial positioning reference for the entire retainer 400. This ensures that the support parts 430 on all the supports 420 are at the same axial height. This ensures that the end faces of all the magnets 300 mounted on the cage 400 are flush; and when the support 430 is embedded in the annular groove 130, it increases the contact area between the cage 400 and the rotor housing 100, providing a larger bonding area for the adhesive applied later, and further improving the overall strength of the rotor housing 100, the magnets 300 and the cage 400; specifically, the outer wall of the annular groove 130 is provided with a stepped surface including at least one step, and the support 430 is provided with a mating surface 431 that fits against the stepped surface, further increasing the contact area between the cage 400 and the rotor housing 100.

[0018] Preferably, such as Figure 6As shown, the connecting ring 410 has hollow holes 411 corresponding to the support column 420. During the assembly process, auxiliary fixtures such as manual tools (e.g., jigs) or automated equipment (e.g., robotic arms) can be precisely inserted into or hooked into these hollow holes 411 to achieve reliable gripping, transportation, positioning, and placement of the cage 400. This allows the cage 400 to be smoothly transferred to the precise position of the rotor mounting slot 101, and in subsequent processes such as applying glue or installing the magnet 300, it can be conveniently positioned and fixed by auxiliary fixtures through the hollow holes 411 to prevent movement. Furthermore, the hollow holes 411 can also be used as glue-filling holes.

[0019] Preferably, the connecting ring 410, the support column 420, and the support part 430 are integrally formed; the connecting ring 410, the support column 420, and the support part 430 of the cage 400 are formed into a complete, interface-free integral structure through one-time molding manufacturing processes such as injection molding or 3D printing, which improves the strength of the cage 400 and eliminates the assembly steps of the cage 400; thereby improving the reliability, durability, and production efficiency of the magneto.

[0020] Preferably, such as Figure 1 , Figure 8 as well as Figure 9 As shown, a central hole 103 is provided at the center of the mounting end 102, and a connecting plate 200 is detachably connected to the central hole 103; the mounting end 102 has multiple connecting through holes 110 that connect it to the rotor mounting groove 101, and the connecting plate 200 has multiple connecting screw holes 220 that correspond one-to-one with the connecting through holes 110. The connecting bolts pass through the connecting through holes 110 and are threaded into the connecting screw holes 220; the rotor housing 100 and the connecting plate 200 are connected by connecting bolts, which facilitates the replacement and maintenance of the connecting plate 200.

[0021] Preferably, such as Figure 1 , Figure 8 as well as Figure 9As shown, the mounting end 102 has multiple first positioning holes 120 communicating with the rotor mounting groove 101. The connecting plate 200 has multiple second positioning holes 210 corresponding to the first positioning holes 120. A positioning post 500 passing through the second positioning hole 210 is fixedly connected in the first positioning hole 120. When installing the connecting plate 200 onto the mounting end 102 of the rotor housing 100, the second positioning holes 210 on the connecting plate 200 must first be aligned with the first positioning holes already fixedly installed on the rotor housing 100. The positioning pin 500 within the 120 is aligned, and under the guidance of the positioning pin 500, the correct installation of the connecting plate 200 is ensured. When the connecting bolts are tightened, the connecting plate 200 is axially pressed, and the positioning pin 500 passes through and fits tightly in the first and second positioning holes 210, effectively preventing relative rotation between the connecting plate 200 and the rotor housing 100. This improves the reliability and durability of long-term operation. Specifically, the positioning pin 500 can be fixed in the first positioning hole 120 by riveting or welding.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
