[0009] Furthermore, a storage groove is provided on the rear side of the guide groove, the storage groove is interconnected with the guide groove, and the storage groove is interconnected with the positioning groove. A guide rod is fixedly connected to the inner wall of the guide groove, and a guide block is slidably connected to the side of the guide rod near the positioning groove. The surface of the guide block is in movable contact with the inner wall of the guide groove.
[0010] Furthermore, the rear side of the guide block penetrates the guide groove and the storage groove and extends into the interior of the storage groove, the surface of the guide block is movably connected to the storage groove, and the front side of the guide block penetrates the guide groove and extends into the exterior of the guide groove.
[0011] Furthermore, the front side of the positioning block movably abuts against the limiting plate. The side of the limiting plate near the storage groove penetrates the storage groove and extends into the interior of the storage groove and is fixedly connected to the guide block. The limiting plate and the storage groove are movably connected. Four fixing plates are fixedly connected around the front side of the drive gear body at equal distances. Two locking holes are symmetrically opened on the side of the fixing plate near the guide block. A threaded locking rod is movably engaged inside one of the locking holes.
[0012] Furthermore, the end of the threaded clasp near the guide block passes through the clasp hole and the guide block in sequence and extends to the outside of the guide block and is fixedly connected with a handle, and the threaded clasp and the guide block are threadedly connected.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] When the gear teeth are damaged, this invention allows for easy disengagement. Simply turn the handle counterclockwise to move the threaded chuck away from the locking hole within the guide block, disengaging it. Then, pull the guide block away from the positioning groove, moving the limiting plate completely into the receiving groove. Align the threaded chuck with another locking hole on the fixing plate, and turn the handle clockwise to insert it into the other locking hole. Pull the drive gear body outward, disengaging the positioning block from the positioning groove and the drive gear body from the mounting sleeve. This allows the drive gear body to be separated from the mounting sleeve, enabling individual replacement of the mounting sleeve and gear teeth instead of the entire assembly, thus reducing replacement costs and minimizing resource waste.

[0023] Please see Figure 1-5 A high-precision drive gear for new energy vehicles includes a drive gear body 1, which is made of high-precision alloy steel. A mounting sleeve 2 is movably fitted on the surface of the drive gear body 1, and several gear teeth 3 are fixedly connected around the outer wall of the mounting sleeve 2 at equal intervals.
[0024] Specifically, a shaft hole 4 is provided at the center of the front side of the drive gear body 1, and four positioning grooves 5 are provided at equal intervals around the front edge of the drive gear body 1. Positioning blocks 6 are movably engaged inside the positioning grooves 5.
[0025] In practice, one side of the positioning block 6 is fixedly connected to the inner wall of the mounting sleeve 2, the rear side of the positioning block 6 is movably abutted against the rear side of the inner wall of the positioning groove 5, and four guide grooves 7 are equally spaced around the front side of the drive gear body 1. The guide grooves 7 are rectangular.
[0026] Specifically, a storage groove 8 is provided on the rear side of the guide groove 7. The storage groove 8 is interconnected with the guide groove 7, and the storage groove 8 is also interconnected with the positioning groove 5. A guide rod 9 is fixedly connected to the inner wall of the guide groove 7. A guide block 10 is slidably connected to the side of the guide rod 9 closest to the positioning groove 5. The surface of the guide block 10 is in movable contact with the inner wall of the guide groove 7, so that the guide block 10 can only slide on the guide rod 9 and cannot deflect on the guide rod 9.
[0027] In practice, the rear side of the guide block 10 passes through the guide groove 7 and the storage groove 8 and extends into the interior of the storage groove 8. The surface of the guide block 10 is movably connected to the storage groove 8. The front side of the guide block 10 passes through the guide groove 7 and extends into the exterior of the guide groove 7.
[0028] Specifically, the front side of the positioning block 6 movably abuts against the limiting plate 11. The side of the limiting plate 11 near the storage groove 8 passes through the storage groove 8 and extends into the interior of the storage groove 8 and is fixedly connected to the guide block 10. The limiting plate 11 and the storage groove 8 are movably connected. Four fixing plates 12 are fixedly connected around the front side of the drive gear body 1 at equal distances. Two locking holes 13 are symmetrically opened on the side of the fixing plate 12 near the guide block 10. A threaded locking rod 14 is movably engaged inside one of the locking holes 13.
[0029] In practical implementation, the end of the threaded rod 14 near the guide block 10 passes through the locking hole 13 and the guide block 10 in sequence and extends to the outside of the guide block 10 and is fixedly connected to the handle 15. The threaded rod 14 and the guide block 10 are threadedly connected.
[0030] In practical applications: When gear tooth 3 is damaged, simply turn handle 15 counterclockwise to move threaded rod 14 away from the locking hole 13 within guide block 10, thus disengaging threaded rod 14 from locking hole 13. Then, pull guide block 10 away from positioning groove 5, causing limiting plate 11 to move completely into receiving groove 8. Align threaded rod 14 with another locking hole 13 on fixing plate 12, then turn handle 15 clockwise to insert threaded rod 14 into the other locking hole 13. Pull drive gear body 1 outward to disengage positioning block 6 from positioning groove 5 and drive gear body 1 from mounting sleeve 2. This allows drive gear body 1 to be separated from mounting sleeve 2. Only mounting sleeve 2 and gear tooth 3 need to be replaced separately, without replacing drive gear body 1, thus reducing replacement costs and minimizing resource waste.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
