Description

Technical Field

[0001] This utility model relates to the technical field of claw pole structures, specifically a generator claw pole that is easy to install. Background Technology

[0002] The claw pole is a core component in the rotor assembly of an automotive alternator. Its main function is to convert the axial magnetic field generated by the excitation coil in the rotor into a radial magnetic field, so that the rotor can obtain an alternating magnetic field distributed in three dimensions in space when it rotates, thereby generating alternating current.

[0003] An existing automotive generator claw pole, such as the one with patent publication number CN209462109U, features an arc-shaped structure on both the inner and outer surfaces of the claw feet, reducing the resistance and friction generated when air flows over the claw pole surface during rotor rotation, thus effectively reducing the noise generated during generator operation. The arc-shaped annular groove structure on the base increases the internal space of the claw pole while ensuring that the claw feet are not easily deformed, which can reduce the resistance generated when air flows over the rotor. The increased internal space of the rotor can also effectively improve the heat dissipation performance of the rotor and reduce the internal temperature of the generator. The rounded chamfer design of each part can further reduce the airflow resistance and reduce the generator operating noise.

[0004] However, the windings in the generator claw poles have not been further improved, which makes it inconvenient to replace the excitation coils on the windings. Utility Model Content

Multiple sets of claw feet 2 are evenly connected to the top circumferential side of the claw pole base 1. A groove 3 is provided on the inner side of the middle of the claw pole base 1. A limiting groove 4 is provided on the upper side of the groove 3 of the claw pole base 1. Three sets of tightening screw grooves 8 are evenly arranged laterally inside the circumferential side of the claw pole base 1. Each set of tightening screw grooves 8 communicates with the interior of the groove 3. The tightening bolt rod 9 is detachably screwed into the inner side of the tightening screw groove 8. The bottom center of the limiting block 5 is connected to the insert block 6. The top ends are connected, and the bottom end of the insert 6 is connected to the winding block 7. During installation, the limiting block 5 is in the upper position, the insert 6 is inserted downward into the groove 3, and the limiting block 5 is placed inside the upper side of the limiting groove 4 for limiting. Then, a set of tightening bolt rods 9 are screwed into each set of tightening screw grooves 8. By turning the bolt head 10, the tightening bolt rod 9 is rotated, and through the screw engagement with the tightening screw groove 8, it acts inward to tighten the insert 6 at that position on the outside, forming the fixation of the claw pole seat 1 and the winding block 7. Subsequently, with the cooperation of the external claw feet 2, the winding block 7 is driven to rotate by the claw pole seat 1, forming a rotating magnetic field to assist in power generation.

[0025] It also includes a tightening contact groove 11, which is provided in the middle of the outer ring side of the insert 6; the tightening contact groove 11 can tighten the tightening bolt rod 9 inward and limit its movement in the upper and lower directions, thereby improving stability.

[0026] It also includes countersunk grooves 14. Each set of tightening screw grooves 8 on the outer ring side of the claw pole seat 1 is provided with a set of countersunk grooves 14. The countersunk grooves 14 can conceal the external bolt head 10 after the tightening bolt rod 9 is tightened, so that it is inside the outer side of the claw pole seat 1 and avoids abruptness.

[0027] It also includes anti-loosening washers 12. Each set of anti-loosening washers 12 is connected to the inner side of the countersunk groove 14 on the outer side of the tightening screw groove 8. The anti-loosening washers 12 can provide internal support for the bolt head 10 after the bolt rod 9 is screwed and tightened, increase static friction, prevent it from rotating and loosening, and improve reliability.

[0028] The claw feet 2 are set into six evenly spaced groups, and the extension angle of each group relative to the center and the interval angle are both 30 degrees. This setting makes it easy to fit and clamp with other claw poles, and has better stability.

[0029] It also includes rounded corners 13. Both the claw base 1 and the claw foot 2 are provided with rounded corners 13 on their outer sides. The rounded corners 13 can reduce friction with the outside air, reduce noise, and improve reliability.

[0030] In summary, when using a generator claw pole that is easy to install, the limiting block 5 is positioned in the upper position, the insert 6 is inserted downwards into the groove 3, and the limiting block 5 is placed inside the upper side of the limiting groove 4 for limiting. Then, a set of tightening bolts 9 are screwed into each set of tightening screw grooves 8. By turning the bolt head 10, the tightening bolts 9 rotate, and through their engagement with the tightening screw grooves 8, they act inwards to tighten the insert 6 at that position. The tightening contact groove 11 allows for inward tightening contact with the tightening bolts 9, providing vertical limiting. The countersunk head... The groove 14 can conceal the external bolt head 10 after the tightening bolt rod 9 is tightened, so that it is inside the outside of the claw pole seat 1 to avoid protrusion. The anti-loosening washer 12 can provide internal support for the bolt head 10 after the tightening bolt rod 9 is screwed on, increase static friction, and prevent it from rotating and loosening, thus fixing the claw pole seat 1 and the winding block 7. Subsequently, with the cooperation of the external claw foot 2, the winding block 7 is driven to rotate by the claw pole seat 1 to form a rotating magnetic field to assist in power generation. At this time, the rounded corner 13 can reduce friction with the external air, reduce noise, and improve reliability.
