Furthermore, the conventional differential cry wheel and the output shaft form a differential gear set; however, 'the differential gear set only needs to be equipped with additional The gearbox needs to reduce the speed. Therefore, the structure of the conventional differential is more complicated during assembly. It can achieve the effect of differential speed. The action of the input shaft can meet the requirements of various types of vehicles. It needs to be equipped with an additional reduction gear box. It also has no integrity and cannot reach the user. As can be seen from the above, the conventional differential has its own characteristics.

The helical gear is provided with a shaft hole at an intermediate position, and the helical gear drives two == shafts and the second helical gear. In addition, the The fourth gear of the differential wheel 4 can rotate in the helical gear and form the teeth of a "man" head, and the two bevel gears are meshed with the end faces of the first bevel gear on opposite sides of the tooth surface, and the second bevel gear shaft Yifeng 1 ^ " is pivoted to an appropriate position. The gear shaft is arranged in the shaft hole; the combination of reduction gears in the reverse gear set can achieve the function of deceleration differential. Next, a comparison will be enumerated. The best example, with the illustrations and figure numbers, will further explain the other purposes and effectiveness of this creation, with a view to enabling the review committee to have a more detailed understanding of this creation and to enable those familiar with the technology to implement it. The following is only to explain the preferred embodiment, not to limit the scope of the original creation. Therefore, any form of modification or modification based on the creative spirit of this creation is a part of it. This creative intention [Embodiment] As shown in the second to fourth figures, this creation is a reduction differential (1) ', which is mainly composed of a reduction gear set (10) and a differential gear set (20 ); The reduction gear set (10) comprises a first gear shaft (11) having a first helical gear (1 1 1), the first helical gear (111) meshes with a shaft 6 M281092 direction perforation The second helical gear (12) of (121), and a second gear shaft (13) with a helical gear (131) is inserted into the perforation (121) of the second helical gear (i2). In addition, the differential gear The group (20) includes a helical gear (21) 'that meshes with the helical gear (131). The helical gear (21) is provided with a shaft hole (211) at an axial intermediate position, and the helical gear (21) drives two A first bevel gear (22), which can be rotated in a helical gear (21) to form opposite tooth surfaces, and is engaged on both end surfaces of the opposite bevel gear of the first bevel gear (22) There is a second bevel gear (23), and a gear shaft (24) is pivotally arranged at a proper axial position of the second bevel gear (23) and the gear shaft (24) is threaded on the shaft (211). Among them, a keyway (122) is formed in the perforation (ι21) of the second helical gear (12) to link the second gear shaft (13) with the helical gear (131). Among them, the first As shown in the figure, the reduction differential (1) can be provided with a shell cover (2). With the above combination, as shown in the second to fourth figures, the first gear shaft of the reduction gear set (丨 〇) (11) It can be driven by a transmission mechanism, so that the first helical gear (111) drives the second helical gear (12), and then the second helical gear (12) through which the second helical gear (12) perforates (1 2 1) (丨 3) Drive the helical gear (; [3 丨) to make the helical gear (131) and the second helical gear (12) rotate synchronously. In this way, the distance between the first helical gear (111) and the second helical gear (12) is used. Cooperate, and then make the helical gear (1 3 1) synchronously rotate to achieve the effect of deceleration '. Moreover, the helical gear (1 3 1) can rotate the helical gear (2 1) of the differential gear set (2 0). The helical gear (21) drives two first bevel gears (22). The first bevel gear (22) can rotate on the helical gear (21), and the first bevel gear (22) 7 M281092 The second bevel gear (23) is meshed on the end faces of both sides, so when the helical gear (21) is turned, the first bevel gear (2 2) will be driven and transmit air & ^ Le second bevel gear (23), and because the first bevel gear (22) revolves horizontally around the mandrel of the inclined TW wheel (2 1), the second bevel gear (2 3) will rotate vertically to the first bevel gear (22) Therefore, the second bevel gears (23) on both sides can provide the gear shafts (24) on both sides at different speeds in poor reading conditions to convey the bite wheels for different road surfaces or turning needs. In summary, we can understand that this creation has the following advantages and practical values: 1) The reduction gear set (1 〇) of this creation uses the _ helical gear (1 1 1) and the first helical gear (12 ), And then make Jingjing go to Dan to make the square gear (131) rotate synchronously, you can achieve the effect of deceleration. 2) The differential gear set (20) Li Shao of this creation _ | the helical gear (21) and the first bevel gear (22) and the second bevel gear (23) are mutually. Straight, so that the second bevel gears (23) on both sides can provide different speeds according to different road sizes. In this way, the function of differential speed can be achieved. Summarizing the above, this creation has the above-mentioned numerous values and can effectively improve the overall economic benefits. Therefore, this creation is indeed an excellent creation, and no identical or similar products are publicly used in the same technical field.
