[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0019] Example:
[0020] See Figure 1 A general-purpose planetary carrier includes a connecting frame and several telescopic components 4 disposed thereon. The telescopic components 4 include a fixed arm 41 and a telescopic arm 42 that can extend and retract on the fixed arm 41. The connecting frame is provided with several connecting parts that can connect to the fixed arm 41. The fixed arm 41 is provided with a fixing member 49 for locking the relative position between the fixed arm and the telescopic arm. The telescopic arm 42 is provided with a connecting column for connecting to the planetary gear 1.
[0021] Among them, see Figure 2 The fixed arm 41 / telescopic arm 42 has a guide telescopic groove 43 on one side and a slider 44 that slides in the guide telescopic groove 43 on the other side. In this embodiment, the guide telescopic groove 43 is opened on the fixed arm 41 and the slider 44 is arranged on the telescopic arm 42.
[0022] The guide telescopic groove 43 / slider 44 has a connecting hole 47 on one side and an oblong hole 48 on the other side, which is arranged along the movement direction of the telescopic arm 42. The fixing member 49 is used to connect the connecting hole 47 and the oblong hole 48. In this embodiment, the guide telescopic groove 43 is a groove with an opening on one side in the movement direction of the telescopic arm 42. The oblong hole 48 is opened on the fixed arm 41, the connecting hole 47 is opened on the telescopic arm 42, and the fixing member 49 is a long bolt that passes through the oblong hole 48 and the connecting hole 47. The telescopic arm 42 is fixed on the fixed arm 41 by means of a nut. Preferably, there are two connecting holes 47 and two fixing members 49.
[0023] The fixed arm 41 and the telescopic arm 42 are provided with anti-loosening parts 45, which are fixed by a connector 46. In this embodiment, the anti-loosening part 45 is a block fixed on the fixed part and the telescopic arm 42, and a threaded hole is opened on the block. The connector 46 is a bolt that can be threadedly connected to the threaded hole on the anti-loosening part 45 on both the fixed arm 41 and the telescopic arm 42.
[0024] Among them, see Figure 3 The connecting frame includes a connecting plate 3 and a clamping plate 2. The connecting part is placed on the connecting plate 3 and / or the clamping plate 2. The fixing arm 41 is placed between the connecting plate 3 and the clamping plate 2. Specifically, the connecting plate 3 / clamping plate 2 has a limiting groove 31. The fixing arm 41 is provided with a locking block 410 that fits into the limiting groove 31. In this embodiment, the limiting groove 31 is an annular groove. The locking block 410 fits into the annular wall of the limiting groove 31. Both the connecting plate 3 and the clamping plate 2 have several through holes 1 that penetrate the limiting groove 31. The locking block 410 also has through holes 2 that can communicate with the through holes on the connecting plate 3 and the clamping plate 2. The connection between the connecting plate 3, the fixing arm 41, and the connecting plate 3 is achieved by passing through the through holes 1 and the through holes 2. The connection between the connecting plate 3, the fixing arm 41, and the connecting plate 3 is also fixed by fixing the long connecting bolt 5 to the power output shaft in the planetary gear mechanism.
[0025] The telescopic arm 42 has a connecting through hole 411, and the connecting column can be detachably connected to the connecting through hole 411. This is a conventional structure and will not be described in detail here.
[0026] Working principle and process:
[0027] When using the planetary carrier of this solution, the through hole 2 on the fixed arm 41 is connected to the through hole 1 on the connecting plate 3 and the clamping plate 2 at appropriate positions using long connecting bolts 5, according to the number and position of the planetary gears 1. Then, it is fixed to the power output shaft in the planetary gear mechanism. Next, the planetary gears 1 are connected to the connecting column, and the fixing member 49 is pre-fixed on the fixed arm 41 and the telescopic arm 42. After adjusting the position, the fixing member 49 is tightened on the fixed arm 41 using nuts. Then, the connecting member 46 is connected to the anti-loosening part 45 to prevent loosening between the fixed arm 41 and the telescopic arm 42. Then, the planetary gears 1 are assembled with the sun gear, etc. Through the above structure, this product can install a corresponding number of telescopic components 4 according to the required number of planetary gears 1 and adjust them to match the mutual spacing of the planetary gears 1. When assembling the planetary gear mechanism, the matching degree between the planetary gears 1 and the sun gear or gear ring is finely adjusted by the telescopic components 4 and fixed by the fixing member 49, realizing the versatility of this product.
