如圖1至圖4所示，本創作所提供動力工具的緩衝式齒輪組件，動力工具包括一馬達10與一傳動組件14，緩衝式齒輪組件設於馬達10與傳動組件14之間，傳動組件14可為衝擊式打擊組或非衝擊式的轉動組件。As shown in Figures 1 to 4, the buffer gear assembly of the power tool provided by this author. The power tool includes a motor 10 and a transmission assembly 14. The buffer gear assembly is arranged between the motor 10 and the transmission assembly 14. The transmission assembly 14 can be an impact-type percussion group or a non-impact-type rotating component.

緩衝式齒輪組件包含一外環座20，外環座20具有一基部22與環設於基部22的外周壁24，外周壁24的內面25設有至少一定位部28，於本較佳實施例的定位部28是以四個凹陷於外周壁24內面25的凹槽作為舉例。The buffer gear assembly includes an outer ring seat 20. The outer ring seat 20 has a base 22 and an outer peripheral wall 24 surrounding the base 22. The inner surface 25 of the outer peripheral wall 24 is provided with at least one positioning portion 28. In this preferred embodiment The positioning portion 28 of the example is four grooves recessed in the inner surface 25 of the outer peripheral wall 24 as an example.

The outer peripheral surface 32 of the inner ring seat 30 is provided with at least one fixing portion 34. The convex part is taken as an example. The inner circumference of the inner ring seat 30 is in the shape of ring teeth and is combined with a planetary gear set 36, and the output shaft 12 of the motor 10 and the transmission assembly 14 are connected through the planetary gear set 36.

外環座20的各定位部28與內環座30的各固定部34相互嵌合，由於定位部28的寬度大於固定部34的寬度，使得外環座20的定位部28在內環座30的固定部34兩側皆形成一可設置緩衝件40的容置空間38，容置空間38位於外環座20與內環座30相互鄰接的圓周位置且沿著外環座20的徑向呈間隔狀排列，緩衝件40介於外環座20與內環座30之間，於本較佳實施例的緩衝件40是以具有彈性材料製成的圓柱體作為舉例，例如橡膠等類似物，當外環座20與內環座30之間受到外力，各緩衝件40即可吸收掉傳遞於外環座20與內環座30之間的部份部份外力。The positioning portions 28 of the outer ring seat 20 and the fixing portions 34 of the inner ring seat 30 are fitted with each other. Since the width of the positioning portion 28 is greater than the width of the fixing portion 34, the positioning portion 28 of the outer ring seat 20 is made to fit into the inner ring seat 30. Both sides of the fixing portion 34 are formed with an accommodating space 38 in which the buffer member 40 can be disposed. The accommodating space 38 is located at a circumferential position where the outer ring seat 20 and the inner ring seat 30 are adjacent to each other and is formed along the radial direction of the outer ring seat 20 Arranged at intervals, the buffer 40 is located between the outer ring seat 20 and the inner ring seat 30.
