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, has high precision and rigidity and is easy to machine and produce. The elastic speed reducer comprises a power input assembly which comprises an input shaft and an elastic component arranged on the input shaft, wherein the elastic component is one or more extrusion type deformation rings. Each extrusion type deformation ring comprises an annular ring body, wherein the outer ring wall and / or the inner ring wall of the annular ring body are / is provided with an elastic structural member. Each elastic structural member comprises two mutually symmetrical elastic piece groups, and each elastic piece group comprises a plurality of first elastic piece sub-groups and secondelastic piece sub-groups distributed on the outer ring wall or the inner ring wall of the corresponding annular ring body; an elastic limiting boss is arranged on the outer ring wall or the inner ring wall of each annular ring body, the first elastic piece sub-groups and the outer ring wall or the inner ring wall of the corresponding annular ring body form included angles toward the correspondingelastic limit boss, and the second elastic piece sub-groups and the outer ring wall or the inner ring wall of the corresponding annular ring body form included angles opposite to the corresponding elastic limit boss.

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...
