Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout.
As shown in fig. 1, the mute gear with a cushioning effect comprises a base gear 1, a movable gear 2 and a fixing member 3, wherein the base gear 1 and the movable gear 2 have the same tooth profile parameters.
As shown in fig. 2, the base gear 1 includes a base gear body 101 and a connecting portion 102 disposed at the center of the base gear body 101, a fixing portion 103 is disposed at the center of the connecting portion 102, a through connecting hole 104 is disposed at the center of the base gear 1, the connecting hole 104 is a spline hole, the connecting portion 102 and the fixing portion 103 are both cylindrical structures, and the diameter of the fixing portion 103 is smaller than that of the connecting portion 102. The side of the connecting part 102 is evenly distributed with protruding positioning parts 105.
