Embodiment 1

[0046] Such as figure 1 , 2 , 3, this embodiment discloses an elastic reducer, including a power input assembly, the power input assembly includes an input shaft 1, an elastic assembly arranged on the input shaft 1, and the elastic assembly is an extrusion-type deformation The extrusion-type deformation ring includes an annular ring body 2, and an elastic structural member is provided on the outer ring wall of the annular ring body.

[0047] In this embodiment, the above-mentioned elastic structure includes two shrapnel groups symmetrical to each other, and each shrapnel group includes a number of first shrapnel groups and second shrapnel groups distributed on the outer ring wall of the annular ring, and the outer ring of the ring ring The wall is provided with an elastic limit boss 23, the first shrapnel group and the outer ring wall of the annular ring form an angle that is biased toward the elastic limit boss, and the second shrapnel group forms an opposite angle to the ou...

Embodiment 2

[0075] refer to figure 1 , 2 , this embodiment is similar to Embodiment 1, disclosing an elastic reducer, including a power input assembly, the power input assembly includes an input shaft 1, an elastic assembly arranged on the input shaft 1, and the elastic assembly is an extrusion One of the differences from Embodiment 1 is that the inner ring wall of the annular ring body is provided with an elastic structural member.

[0076] In this embodiment, the above-mentioned elastic structure includes two shrapnel groups that are symmetrical to each other, and each shrapnel group includes a number of first shrapnel groupings and second shrapnel groupings distributed on the inner wall of the annular ring. There is an elastic limit boss, the first shrapnel group and the ring wall inside the annular ring form an angle that is biased towards the elastic limit boss, and the second shrapnel group and the inner ring wall of the annular ring form a reverse elastic limit boss angle. Each ...

Abstract

The invention provides an elastic speed reducer which can effectively overcome errors and eliminate abnormal vibration waves and is high in precision and rigidity and easy to process and produce. Theelastic speed reducer comprises a power input assembly, and the power input assembly comprises an input shaft and an elastic assembly arranged on the input shaft. The elastic assembly comprises one ormore extrusion type deformation rings. Each extrusion type deformation ring comprises an annular ring, wherein the outer ring wall and / or the inner ring wall of the annular ring are / is provided withan elastic structure component. Each elastic structure component comprises two symmetrical elastic sheet sets. Each elastic sheet set comprises a plurality of first elastic sheet subsets and a plurality of second elastic sheet subsets, and the first elastic sheet subsets and the second elastic sheet subsets are distributed on the outer ring walls or the inner ring walls of the annular rings; the outer ring walls or the inner ring walls of the annular rings are provided with elastic limiting bosses; and included angles towards the elastic limiting bosses are formed between the first elastic sheet subsets and the outer ring walls or the inner ring walls of the annular rings, and included angles opposite to the elastic limiting bosses are formed between the second elastic sheet subsets and the outer ring walls or the inner ring walls of the annular rings.

Description

technical field [0001] The invention relates to the technical field of elastic reducers, in particular to elastic reducers. Background technique [0002] The deceleration mechanism is widely used in high-load and high-precision industries such as robots and automobiles. As a key mechanical transmission component, the deceleration mechanism is crucial to the performance of robots, automobiles and other products. In particular, the robot industry is developing rapidly, and the market's enthusiasm for more precise, lightweight, and intelligent robots has also put forward higher requirements for the deceleration mechanism that realizes the fine movements of robot joints. [0003] The existing reducer mainly realizes transmission through gears, worm gears or sprocket chains. The commonly used reducers on the market mainly include needle-toothed cycloid reducers and harmonic reducers. However, no matter the pin-toothed cycloid reducer or the harmonic reducer, there are theoretic...
