Description

Technical Field

[0001] This utility model belongs to the field of differential gear technology, specifically relating to a differential gear with a lightening groove. Background Technology

[0002] A gear is a mechanical component with teeth on its rim that continuously meshes to transmit motion and power. Gears have been used in power transmission for a long time. With the development and progress of science and technology, the smoothness of gear operation has become increasingly important.

[0003] The differential is a core component of a car's transmission system. Its main function is to allow the left and right drive wheels to rotate at different speeds when the car is turning, ensuring pure rolling and reducing tire wear and driving resistance. As a key transmission component of the differential, the performance of the differential gears directly affects the differential's transmission efficiency, operating noise, and service life.

[0004] Existing differential gears typically use a solid structure, resulting in significant weight and increased inertial losses during transmission. These increased inertial losses negatively impact a vehicle's range. Therefore, it is necessary to provide a differential gear with a weight-reducing groove. Utility Model Content

[0005] The purpose of this invention is to overcome the technical problems existing in the prior art and to provide a differential gear with a lightening groove.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a differential gear with a weight reduction groove, comprising: a gear body, wherein a weight reduction structure is provided on the outer wall of the gear body, and a reinforcement structure is installed inside the weight reduction structure;

[0007] The weight reduction structure includes a recessed groove on the outer wall of the gear body, a weight reduction groove on the inner wall of the recessed groove, and multiple through grooves on the weight reduction groove.

[0008] The gear body has an annular groove in the middle and a dividing groove at intervals on the gear body.

[0009] Furthermore, the annular groove and the dividing groove have a triangular structure, and the through groove has a circular structure.

[0010] Furthermore, the reinforcement structure includes multiple reinforcement frames integrally formed with the surface of the gear body. The reinforcement frames are hollow and have an overall triangular pyramidal structure.

[0011] Furthermore, the inner wall of the weight-reducing groove is integrally formed with multiple reinforcing strips. The reinforcing strips have an arc-shaped structure and can reinforce the weight-reducing groove to avoid the problem of reduced strength of the gear body due to insufficient thickness.

[0012] Furthermore, chamfers are provided at both ends of the outer wall of the weight-reducing groove, which can increase the strength of the inner and outer ends of the weight-reducing groove of the gear body.

[0013] Furthermore, a central groove is installed and fixed inside the gear body. The two ends of the central groove are in the same plane as the teeth of the gear body, and the central groove is used to connect with the shaft.

[0014] Compared with the prior art, this utility model has the following beneficial effects: In use, by opening a recessed groove inward on the outer wall of the gear body, the teeth on the gear body protrude outward, thereby reducing the overall weight of the gear body. Further opening a weight-reducing groove inward on the outer wall of the recessed groove can greatly reduce the overall weight of the gear. The annular groove in the middle of the gear body, combined with the opening of the dividing groove, can effectively reduce the weight of the gear body teeth. Moreover, the spaced opening can enhance the overall strength of the gear body by using gear body teeth without dividing grooves. In addition, the reinforcement frame with triangular pyramid structure connected to the protruding teeth can strengthen the strength of the teeth. While ensuring the overall strength of the gear body, the weight of the gear body is reduced to the maximum extent, avoiding the impact of inertia caused by excessive weight on the vehicle's range during transmission.

[0025] Example 1

[0026] Figure 1 A differential gear structure diagram with a light-reducing groove is provided for an embodiment of this utility model, as shown below. Figure 1 , Figure 2 As shown, the gear body 1 has a weight-reducing structure 2 on its outer wall, and a reinforcing structure 3 is installed and fixed inside the weight-reducing structure 2. The weight-reducing structure 2 includes a recessed groove 21 on the outer wall of the gear body 1, a weight-reducing groove 22 on the inner wall of the recessed groove 21, and multiple through grooves 23 on the weight-reducing groove 22. An annular groove 24 is provided in the middle of the gear body 1, and a dividing groove 25 is provided at intervals on the gear body 1.

[0027] The annular groove 24 and the dividing groove 25 have a triangular structure, while the through groove 23 has a circular structure. The triangular structure of the annular groove 24 and the dividing groove 25 can increase the stability of the groove.

[0028] The reinforcement structure 3 includes multiple reinforcement frames 31 integrally formed with the surface of the gear body 1. The reinforcement frames 31 are hollow structures and the overall reinforcement frame 31 is a triangular pyramid structure. The overall triangular pyramid structure of the reinforcement frame 31 can increase the stability of the reinforcement frame 31 and can also provide multi-angle support for the teeth of the gear body 1.

[0029] Example 2

[0030] Based on Embodiment 1, the present invention can be further improved in the following ways, such as... Figure 2 and Figure 3 As shown, the inner wall of the weight reduction groove 22 is integrally formed with multiple reinforcing strips 32. The reinforcing strips 32 have an arc-shaped structure and can reinforce the weight reduction groove 22 to avoid the problem of reduced strength of the gear body 1 due to insufficient thickness.

[0031] Both ends of the outer wall of the weight reduction groove 22 are chamfered, which can increase the strength of the inner and outer ends of the weight reduction groove 22 of the gear body 1.

[0032] A central groove 4 is installed and fixed inside the gear body 1. The two ends of the central groove 4 are in the same plane as the teeth of the gear body 1. The central groove 4 is used to connect with the shaft.

[0033] Working principle: During use, the gear body 1 has an inward recessed groove 21 on its outer wall, causing the teeth on the gear body 1 to protrude outward, thereby reducing the overall weight of the gear body 1. Furthermore, the inward recessed weight-reducing groove 22 on the outer wall of the recessed groove 21 can further reduce the overall weight of the gear. The annular groove 24 in the middle of the gear body 1, together with the dividing groove 25, can effectively reduce the weight of the gear teeth. The spaced grooves can enhance the overall strength of the gear body 1 by using the teeth without dividing grooves 25. In addition, the reinforcing frame 31 with a triangular pyramid structure is connected to the protruding teeth to strengthen the teeth and ensure that the teeth can be well supported at all stress angles. While ensuring the overall strength of the gear body 1, the weight of the gear body 1 is reduced to the minimum. During the operation of the gear body 1, the reinforcing strip 32 can provide sufficient support to ensure the strength of the gear body 1 during operation.
