Description

Technical Field

[0001] This utility model relates to the field of electric gun drill technology, and in particular to a gear ring for a reducer in an electric gun drill. Background Technology

[0002] The gear ring of a reducer used in electric drills, simply put, is the largest ring gear in the reducer. It is one of the key core components of the reducer, responsible for transmitting power from one transmission stage to the next, or to the output mechanism, while simultaneously achieving the core functions of deceleration and torque increase.

[0003] Most existing gear rings adopt a plain plate structure, that is, the gear is only machined on the ring base, which has weak structural strength and rigidity. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a reducer gear ring for electric gun drills.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A gear ring for an electric gun drill reducer includes a gear ring base, which is integrally formed from a gear ring ring and a reinforcing ring. The inner ring of the gear ring ring has a number of teeth arranged in an annular array, and the bottom end face of the reinforcing ring has an annular groove. Three sets of main reinforcing ribs are arranged at equal intervals in the annular groove, and six sets of auxiliary reinforcing blocks are fixedly arranged in an annular array in the annular groove. I-shaped reinforcing blocks that connect with the annular groove are fixedly installed on the bottom end face of the reinforcing ring between two adjacent sets of auxiliary reinforcing blocks.

[0006] In addition, a preferred structure is that both sides of the bottom end of the I-shaped reinforcing block are provided with inclined surfaces.

[0007] Furthermore, in a preferred configuration, the bottom end face of the auxiliary reinforcing block is flush with the bottom end face of the reinforcing ring.

[0008] Furthermore, in a preferred configuration, the end face of the inner ring of the reinforcing ring is flush with the end face of the tooth portion.

[0009] Furthermore, in a preferred configuration, an extended reinforcing ring is fixedly installed on the inner side of the bottom end face of the reinforcing ring, and the thickness of the extended reinforcing ring is less than the thickness of the I-shaped reinforcing block.

[0010] Furthermore, a preferred structure is that the cross-section of the annular groove is arc-shaped.

[0011] The beneficial effects of this utility model are as follows: In this invention, a gear ring is formed by combining a gear ring base and a gear section. Furthermore, the overall structural rigidity and strength of the gear ring can be enhanced by the coordinated arrangement of I-shaped reinforcing blocks, main reinforcing ribs, auxiliary reinforcing blocks, and extended reinforcing rings.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-3 The gear ring of the reducer for electric gun drills includes a gear ring base 11, which is integrally formed from a gear ring ring 111 and a reinforcing ring 112. The inner ring of the gear ring ring 111 has a plurality of teeth 12 arranged in an annular array, and the bottom end face of the reinforcing ring 112 has an annular groove 13 with a circular arc cross-section. The annular groove 13 reduces the weight of the reinforcing ring 112, and the circular arc transition effectively avoids stress concentration at right angles or sharp corners. The specific structure and connection method of the gear ring base 11 and the teeth 12 are currently publicly available technologies.

[0016] Three sets of main reinforcing ribs 15 are evenly spaced within the annular groove 13, and six sets of auxiliary reinforcing blocks 16 are fixedly arranged in a ring array within the annular groove 13. The auxiliary reinforcing blocks 16, along with the main reinforcing ribs, provide distributed support and ensure the structural rigidity of the gear ring. I-shaped reinforcing blocks 14, which connect to the annular groove 13, are fixedly installed on the bottom surface of the reinforcing ring 112 between adjacent sets of auxiliary reinforcing blocks 16. Inclined surfaces are provided on both sides of the bottom end of the I-shaped reinforcing blocks 14. The inclined surfaces ensure that the I-shaped reinforcing blocks 14 reduce weight while increasing the structural strength of the gear ring.

[0017] Since the bottom end face of the auxiliary reinforcing block 16 is flush with the bottom end face of the reinforcing ring 112, the gear tooth end face is provided with axial support, especially when subjected to axial impact force, preventing minor axial bending or deformation of the teeth. Furthermore, the end face of the inner ring of the reinforcing ring 112 is flush with the end face of the tooth 12, providing a stable and complete mounting reference surface for the gear ring. An extended reinforcing ring 17 is fixedly installed on the inner side of the bottom end face of the reinforcing ring 112, and the thickness of the extended reinforcing ring 17 is less than the thickness of the I-shaped reinforcing block 14. Three sets of main reinforcing ribs 15 are provided within the annular groove 13 to enhance the structural strength of the reinforcing ring 112. In this invention, a gear ring is formed by combining a gear ring base 11 and a gear portion 12. Furthermore, the overall structural rigidity and strength of the gear ring can be enhanced by the coordinated arrangement of an I-shaped reinforcing block 14, a main reinforcing rib 15, an auxiliary reinforcing block 16, and an extended reinforcing ring 17.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
