Embodiment Construction

[0012] Such as figure 1 , figure 2 and image 3 As shown, a planetary reducer with small tooth difference includes a frame 1, a power input shaft 2, the power input shaft 2 is rotated on the frame 1 through the first bearing 3, and the input shaft 2 is fixed in two opposite directions. The eccentric shaft sections 21, 22 of the two eccentric shaft sections 21, 22 are respectively provided with gears 5 through the second bearing 4, the shapes of the two gears 5 are the same, and the outsides of the two gears 5 are respectively meshed with the same internal gear 6, The meshing parts of the two gears 5 and the internal gear 6 are located on the opposite sides of the internal tooth pattern of the internal gear 6, and a plurality of through holes 51 are evenly distributed around the periphery of the two gears 5, and each through hole 51 is provided with a cross section smaller than The positioning pin 7 of the through hole section is fixedly arranged on the frame 1 . In this em...

Abstract

The invention relates to a planetary reducer with small teeth differences. According to the technical scheme, the planetary reducer with small teeth differences is characterized by comprising a frame and a power input shaft; the power input shaft is rotationally arranged on the frame through a first bearing; two eccentric shaft sections with opposite direction are fixedly arranged on the power input shaft and are provided with gears through a second bearing respectively; the two gears are in the same shape, and the outer portions of the two gears mesh with a same inter gear respectively; the meshing positions of the two gears and the inter gear are located on the corresponding side faces of inter teeth thread of the inter gear; and a plurality of through holes are evenly distributed on the peripheries of the two gears, a positioning pin is arranged in each through hole, a sliding pin sleeve is sleeved on each positioning pin, and the positioning pins rotationally match with the through holes of the gears through the sliding pin sleeves. The novel planetary reducer is reasonable in structure, low in cost and large in output torque.

Description

technical field [0001] The invention relates to a reducer with large output torque. Background technique [0002] At present, there are many types of reducers with various structures on the market, and most of them are decelerated through gear sets. This type of reducer has a small output torque, and its use is limited. In addition, the internal structure is also relatively complicated, and the cost is relatively high. High, poor versatility. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art and provides a novel planetary reducer with less tooth difference with reasonable structure, low cost and large output torque. [0004] To achieve the above object, the present invention adopts the following technical solution: a planetary reducer with small tooth difference, characterized in that: it includes a frame, a power input shaft, and the power input shaft is arranged on the frame through the rotation of the first bearing, and on...
