[Prior Art] [0002] According to the development of industry and commerce, locomotives are not only the means of transportation that many people rely on, but also the extreme sports tools for racing, and many young people, for the sake of fashion and racing, have Helping the car to change and change the internal transmission mechanism to make it more powerful, faster and better, and so on, the locomotive modification market is booming. [0003] For the conventional locomotive stepless transmission gearbox transmission system, please refer to the "Renovation of the stepless gearbox structure with reverse gear function" of the Republic of China Bulletin No. M 2 6 7 0 9 5, and please refer to it together. Please refer to the fourth to fifth figures, which mainly consists of a drive shaft (4) that receives the engine power drive, a drive shaft (5) and an output shaft (not shown), and a drive shaft is provided with a The driving gear (4 1 ), the driving gear (4 1) meshes to drive the driven gear (5 1 ), so that the transmission shaft (5) rotates and then drives the reduction gear (not shown) disposed thereon, and then uses the reduction gear Engagement drives the shifting gear on the output shaft (not shown), which in turn drives the output shaft to rotate forward. [〇〇〇4] However, the drive gear (4 1 ) on the drive shaft (4) and the corresponding driven driven gear (5 1 ) have the same width of the two gears, and the drive gear (4 1 ) and the driven gear (5 1 ) The unengaged part adds the form number A0101 Page 3 of 14 [0005] The overall weight of the locomotive affects the performance on the race, in order to make the locomotive lighter and faster, for the locomotive gearbox transmission The gear structure of the system is a subject worthy of further consideration and improvement in the industry. [New content] The reason is that the creators have improved the creation of a locomotive gearbox gear set with the rich experience in design and development and actual production of the relevant industry for many years. The purpose is to provide a reduction in the axial length of the drive gear and The locomotive gearbox gear set is improved by providing perforations on the driven gear toothed disc to reduce the overall weight of the locomotive and enhancing the structural strength of the driven gear. [0006] In order to achieve the above-mentioned implementation purpose, the present author has developed the following implementation techniques. The main shaft of the locomotive is provided with a driving shaft for driving the engine power, a driving shaft and an output shaft, and a driving gear is fixed on the driving shaft, and the driving shaft has a through hole penetrating through the shaft; the driving gear The meshing drive is fixed to the driven gear of the transmission shaft, so that the transmission shaft rotates and then drives the reduction gear fixed thereon, and then the reduction gear meshes to drive the transmission gear fixed on the output shaft, thereby driving the output shaft to rotate; The axial length of the tooth groove of the drive gear is equal to the axial length of the ring groove outside the driven gear And a chamfer is formed between the ring gear groove and the toothed disc in the radial direction of the driven gear, and a convex step is arranged on the toothed disc of the driven gear, and the protruding step is provided with a shaft hole through which the transmission shaft is inserted. Then, a plurality of perforations around the convex step are formed on the tooth plate. Thereby, the mutual meshing of the driving gear and the driven gear not only does not affect the function of the engine to transmit power, but also helps to reduce the weight of the locomotive, and the plurality of perforations of the driven gear toothed disc can also reduce the driven gear. Form No. A0101 Page 4 of 14 [0007] Repetitive, making the locomotive racing more advantageous; in addition, the design of the chamfer between the % cogging and the sprocket outside the driven gear can increase the driven gear The structural strength makes the wheel longer. [Embodiment] _8] The purpose of this creation and its structural and functional advantages will be explained in accordance with the structure shown in the following figure, in conjunction with specific examples, so that the review committee can have a deeper and more specific understanding of the creation. [_9] First, as shown in the first to third figures, the modified locomotive gearbox gear set is mainly installed in the locomotive gearbox, which includes: a drive shaft, which is a receiving engine (not shown) a drive of power, and a drive gear (丄丄) is fixed thereon; Π] a drive shaft (2) on which a driven gear (2 1 ) meshing with the drive gear (Work 1) is respectively fixed And a reduction gear (2 2), the rotation of the driven gear (2 1 ) drives the transmission shaft (2) to rotate, thereby rotating the reduction gear (22); wherein the driven gear (21) has a tooth The disk (212) and the ring are disposed outside the ring gear (2丄2) outside the ring groove (2 1 1 ), and the axial length of the tooth groove of the drive gear (丄i) is equal to the driven gear (2 i The axial length of the outer ring gear groove (211), and the radial gear groove (21 | ) outside the driven gear (2 丄) and the toothed disk (2 1 2) are radially formed with a 隹j angle (2 1 3), in the present embodiment, the chamfer (213) is at an angle of 45 degrees with the axial direction; then, the toothed disc (21 2) of the driven gear (2 i ) is provided with a convex step (2) 14), The axial step of the shaft hole (?, Form No. A0101, page 5/14 pages M413610 convex: (1) 4) relative to the axial length of the toothed disc (212) is provided on the convex step (21 4 ). The length is greater than the axial length of the outer ring cogging (211) relative to the sprocket (212); in addition, a plurality of perforations (2 16) '· and [ around the convex step (214) are formed on the pure (212). 0012] [0013] an output shaft (3) on which a shift gear (31) coupled to a reduction gear (Μ) is fixed, and the output shaft is driven by a reduction gear (22 shift gear (3 1)) (3) (4) Movement 0 In addition, the drive shaft (1) has a through hole (work 2) that penetrates the shaft center to reduce the overall weight of the locomotive. _ According to the locomotive gearbox gear set described above, when it is improved in implementation, when When the engine drive master (i) rotates, the drive gear (11) on which the drive is driven rotates, and drives the driven gear (2 1 ) that meshes with it to rotate, causing the drive shaft (2) to rotate and then drive the fixed gear. The upper reduction gear (2 2) rotates, and the shift gear (3 1 ) that meshes with the reduction gear (2 2) is driven again to finally power Output shaft (3) output; since the axial length of the tooth groove of the drive gear (ii) is equal to the axial length of the ring gear groove (2丄丄) other than the driven gear (21), it does not affect the drive gear (丄丄) and the driven gear (2丄) mesh with each other to transmit power, and compared to the conventional drive gear (41) (please refer to the fifth figure together), the axial length is smaller, which is more advantageous. In order to reduce the weight of the locomotive, and the chamfering (2 1 3) between the ring gear groove (2 1 1) and the toothed disk (2 1 2) outside the driven gear (2 1), the driven gear can be increased ( 2 n structural strength; in addition, the driven gear (21) is provided with a plurality of forms on the chainring (2 i 2) minus A0101 Page 6 / 14 pages [0015] Perforation around the convex step (2 1 4) (2 1 6), it can also reduce the weight of the driven gear (21), thereby reducing the overall weight of the locomotive, which can be more advantageous in racing. It can be seen from the above description that the present invention has the following advantages compared with the prior art: [0016] 1. This creation reduces the axial length of the tooth groove of the drive gear to the outer ring of the driven gear. The axial length of the cogging is equivalent, which not only does not affect the function of the driving gear and the driven gear to reciprocate to transmit power, and is more advantageous for reducing the weight of the locomotive. 2. This design has a chamfered design between the ring gear groove and the toothed disc outside the driven gear, which increases the structural strength of the driven gear and makes the gear life longer. 3. This creation creates a plurality of perforations in the gear plate of the driven gear, which can also reduce the weight of the driven gear, thereby reducing the overall weight of the locomotive, which makes the racing more advantageous.
