Description

Technical Field

[0001] The utility model relates to the technical field of output shafts and gear rings, in particular to an integrated output shaft and gear ring structure. Background Art

[0002] The output shaft, also known as the secondary shaft, is a shaft in a vehicle's transmission. It connects directly to the drive shaft (transmission shaft), outputting torque and speed, which then propel the vehicle through the differential. When the vehicle's starter is cranked, the drive gear and the engine's flywheel ring gear produce a clashing, idling sound, which can cause deformation of the transmission structure or increase the gap between them. Therefore, the output shaft often requires the ring gear to work in conjunction with it to avoid the impact caused by this gap.

[0003] However, the existing output shaft and ring gear are usually split structures. The ring gear and output shaft are processed and installed separately, so the processing accuracy, installation accuracy and installation process requirements are also relatively high; and the installation stability between the two is general, which to a certain extent affects the stability of the related product device and poses a risk of use.

[0004] To this end, we propose an integrated output shaft gear ring structure to overcome the above problems. Utility Model Content

[0006] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: an integrated output shaft gear ring structure, including a gear ring connector, a first mold assembly, an output shaft connector, a second mold assembly and a flange. The gear ring connector, the first mold assembly, the output shaft connector, the second mold assembly and the flange are arranged in sequence along the length direction of the output shaft gear ring structure.

The first end of the output shaft connector is connected to the first mold assembly, and the second end of the output shaft connector is connected to the second mold assembly. The flange is integrally fixedly connected to the output shaft connector through the second mold assembly.

[0007] In order to further improve the usability of the integrated output shaft gear ring structure, the solution adopted by the present invention is that a gear ring for transmitting power is sleeved on the inner side wall of the gear ring connector.

[0008] In order to further improve the usability of the integrated output shaft gear ring structure, the present invention adopts a solution in which a plurality of assembly holes are provided on the outer edge of the end surface of the gear ring connector.

[0009] In order to further improve the usability of the integrated output shaft gear ring structure, the present invention adopts a solution in which an annular inner cavity for meshing connection is formed inside the gear ring connector.

[0010] In order to further improve the usability of the integrated output shaft gear ring structure, the present invention adopts a solution in which the first mold assembly is fixedly connected to the gear ring connector via an outer edge support sleeve.

[0011] In order to further improve the usability of the integrated output shaft gear ring structure, the present invention adopts a solution in which a plurality of shaft spline grooves are evenly arranged on the second mold assembly around its central axis.

[0012] In order to further improve the usability of the integrated output shaft gear ring structure, the solution adopted by the present invention is: the position and size of the first mold assembly are correspondingly adapted to the output shaft connector, and the length of the first mold assembly is smaller than the length of the output shaft connector.

[0013] In order to further improve the usability of the integrated output shaft gear ring structure, the present invention adopts the solution that the second mold assembly is adapted to the position and size of the output shaft connector, and the length of the second mold assembly is smaller than the length of the output shaft connector.

The first end of the output shaft connector 3 is connected to the first mold assembly 2, and the second end of the output shaft connector 3 is connected to the second mold assembly 4. The flange 8 is integratedly fixed with the output shaft connector 3 through the second mold assembly 4. The gear ring connector 1 of the utility model is integrated and fixed with the output shaft connector 3, and the gear ring connector 1 can be directly connected to the transmission disconnection of the automobile starter, thereby completing the drive connection between the output shaft connector 3 and the automobile starter.

[0025] In summary, the output shaft gear ring 6 structure is set up through an integrated compact structure to maintain high torque and high load, while reducing the corresponding volume, facilitating installation, saving space, and effectively expanding the installation application range. This integrated output shaft gear ring 6 structure also improves the overall accuracy and rigidity of the output shaft and gear ring 6.

This integrated output shaft gear ring 6 structure reduces the cost of in-stock materials by setting up an integrated output shaft gear ring 6, and also improves the stability of the product device, reduces consistency risks, and effectively improves the strength of the integrated output gear ring 6, solving the problem that the existing output shaft and gear ring 6 are usually split structures, and the gear ring 6 and the output shaft are processed and installed separately, so their processing accuracy, installation accuracy, and installation process requirements are also relatively high; and the installation stability between the two is general, which affects the stability of the related product device to a certain extent and has a use risk.

The inner circle and outer circle of the gear ring 6 are divided into small gears, and the transmission function of the mechanical device is realized through the meshing between the teeth of the gears. The gear ring 6 is usually made of steel or cast iron, and has high hardness and wear resistance. When power is transmitted through the gear ring 6, it can withstand a certain load and be used for speed regulation and speed change of mechanical equipment; the outer edge of the end face of the gear ring connector 1 is provided with several assembly holes 7 (that is, the assembly holes 7 include but are not limited to positioning holes, screw holes, etc.); the interior of the gear ring connector 1 forms an annular inner cavity 10 for meshing connection, which is connected to other gear structures through the gear ring connector 1, and has sufficient idling gap to improve the meshing effect.

[0027] Furthermore, the first mold assembly 2 (the first mold assembly 2 can be a sleeve structure, and the sleeve structure is a straight-through sleeve series) is fixedly connected to the ring gear connector 1 through an outer edge support sleeve 9.

The second mold assembly 4 is adapted to the position and size of the output shaft connector 3, and the length of the second mold assembly 4 is less than the length of the output shaft connector 3.
