Embodiment Construction

[0022] This specific embodiment provides a planetary reducer, which can avoid the problem that the gears of the reducer are easily damaged when the torque increases instantaneously.

[0023] Hereinafter, an embodiment will be described with reference to the drawings. In addition, the examples shown below do not limit the content of the invention described in the claims in any way. In addition, all the contents of the configurations shown in the following embodiments are not limited to be essential to the solution of the invention described in the claims.

[0024] see Figure 1-Figure 4 , a planetary reducer provided in this specific embodiment includes an inner ring gear 11 , a planetary gear 12 , a case 13 and an elastic buffer 14 .

[0025] Wherein, the planetary gear 12 meshes with the inner teeth of the inner ring gear 11 and revolves along the inner ring of the inner ring gear 11. The inner ring gear 11 is set inside the box body 13, and the inner ring gear 11 can move ...

Abstract

The invention discloses a planetary reducer which comprises an inner gear ring, a planetary gear and a box body, wherein the planetary gear meshes with the inner teeth of the inner gear ring and can revolve around the inner ring of the inner gear ring; the box body is sheathed on the periphery of the inner gear ring; the inner gear ring is rotatablely arranged in the box body; an elastic cushion is arranged between the box body and the periphery of the inner gear ring; and when the inner gear ring rotates, the elastic cushion generates elastic force opposite the rotation direction of the inner gear ring. Thus, the planetary reducer disclosed by the invention can avoid the problem of high damage tendency of the reducer gear when the torque instantaneously increases.

Description

technical field [0001] The present invention relates to the technical field of reducers, more specifically, to a planetary reducer. Background technique [0002] In recent years, my country's infrastructure construction market has begun to accelerate growth, and planetary reducers have been widely used in construction machinery and equipment. [0003] The planetary reducer is a planetary reduction gear device used to reduce the output speed of the prime mover and increase the output torque. Compared with ordinary cylindrical gear reducers, planetary reducers have the advantages of small size, light weight, high load capacity, large transmission ratio range, and high transmission efficiency. In the application of construction machinery, the rotary operation of the platform rotary reducer is more frequent during the construction process. In the process of acceleration or deceleration, due to the instantaneous increase of the driving torque, the gears of the slewing reducer o...
