DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] As Figures 1 to 6As shown in the figure, a combined reduction gearbox gear includes a first gear body 1 and a second gear body 2, which are combined to form this gear structure. At the center position of the outer end face of the second gear body 2, there is an integrally formed first fitting and mounting post 3. On the end face of the second gear body 2 adjacent to the first gear body 1, there is a cylindrical second fitting and mounting post 4 that completely penetrates from the outer end face of the first gear body 1, and they are used for connection and cooperation during installation. On the outer cylindrical surface of the second fitting and mounting post 4, there are fitting stability limiting posts 5, which make the combined stability during fitting better. On the outer cylindrical surface of the first gear body 1, there is a first gear fitting groove, and on the outer cylindrical surface of the second gear body 2, there is a second gear fitting groove 7. They are the fitting gear grooves at various positions and can be fitted with different gear structures together. On the end face of the first gear body 1 adjacent to the second gear body 2, there is a cylindrical safety lubrication fitting groove 6 with the same central axis as the second gear body 2. It can ensure that the lubricating fluid can be fully coordinated at the fitting position between the two gear structures during use. The projection of the second gear fitting groove 7 on the end face of the first gear body 1 intersects with the safety lubrication fitting groove 6. The inner cylindrical surface of the safety lubrication fitting groove 6 is located outside the inner side surface of the second gear fitting groove 7, and the outer cylindrical surface of the safety lubrication fitting groove 6 is located in the outer area outside the outer side surface of the second gear fitting groove 7, making the structural strength at the central position better. When coordinating with the lubricating fluid, the lubrication can fully cooperate with the second gear fitting groove 7 and does not affect the strength of the end face of the first gear body. It has better heat dissipation cooperation during use and can drive more heat for dissipation during the lubrication process, ensuring better overall structural durability. On the outside of the safety lubrication fitting groove 6, there are evenly distributed circumferential heat dissipation and lubrication transition holes 8, which completely penetrate the two end faces of the first gear body 1. It can perform lubricating fluid transition and delivery cooperation for the first gear structure and can dissipate heat more efficiently, ensuring reliable heat resistance during later use. It adopts a new structural design, directly combines the two gears during production, and by setting a safety lubrication structure at the fitting position, it can effectively improve the fitting safety between the gear sets, ensure the fitting accuracy between the gears, make the installation operation more convenient, have more comprehensive cooperation of the lubricating fluid between adjacent gears during use, and at the same time ensure the heat resistance of the structure between the gears, having a more reliable durability effect during use, effectively improving the service life of the gear set and the safety during use.
[0020] Preferably, on the outer edge positions of the first fitting and mounting post 3 and the second fitting and mounting post 4 respectively, there are fitting chamfer structures for convenient installation, which are more convenient for installation and cooperation operations, have the function of fitting guidance, and make the fitting efficiency during assembly combination higher.
[0021] Preferably, the heat dissipation and lubrication transition hole 8 has a cylindrical structure, and the central axis of the heat dissipation and lubrication transition hole 8 is located on the outer cylindrical surface of the safety lubrication fitting groove 6, making this structure more convenient for production and processing, the reference points during the production process are easier to align, and the position accuracy of the processing structure is higher.
[0022] Preferably, the number of the heat dissipation and lubrication transition holes 8 is the same as the number of the second gear fitting grooves 7, so that the overall fluidity during the lubricating fluid fitting can be better, and a more comprehensive lubricating fit can be carried out on the gear combination.
[0023] Preferably, the heat dissipation and lubrication transition hole 8 is located in the outer region corresponding to the second gear fitting groove 7, so that the lubricating fluid will not affect the second gear structure during fitting, ensuring better strength of the main structure and stronger durability during later use.
[0024] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements or substitutions can be made, and these improvements or substitutions should also be regarded as the protection scope of the present invention.
