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 elastic structure includes two shrapnel groups that are symmetrical to each other, and each shrapnel group includes five shrapnels 21 distributed on the half side of the outer wall of the annular ring;

[0048] Wherein, each shrapnel group includes the first shrapnel starting from one end of the half of the outer ring wall of the annular ring, N intermediate shrapnels and the N+2th shrapnel ending at the other end of the half of the outer ring wall of the ring ring, N is equal to or greater than 1. In this embodi...

Embodiment 2

[0076] 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, and the elastic assembly is an extrusion type Deformation ring, the extrusion-type deformation ring includes an annular ring body 2, 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.

[0077] 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 shrapnels distributed on the half side of the inner wall of the annular ring; each shrapnel group includes The first shrapnel at one end of the half side, the N middle shrapnels and the N+2th shrapnel ending at the other end of the inner wall of the annular ring, N is equal to or greater than 1. ...

Abstract

The invention provides an elastic speed reducer which can effectively overcome errors and eliminate abnormal oscillatory waves and is high in precision and rigidity and easy to machine and produce. The elastic speed reducer comprises a power input assembly. The power input assembly comprises an input shaft and an elastic assembly arranged on the input shaft. The elastic assembly is one or more extrusion type deformable rings. Each extrusion type deformable 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 elastic structural body, each elastic structural body comprises two symmetrical elastic slice sets, each elastic slice set comprises a plurality of elastic slices distributed on half side of the outerring wall or the inner ring wall of the annular ring body, each elastic slice set comprises a first elastic slice started at one end of half side of the outer ring wall and the inner ring wall of theannular ring body, N middle elastic slices and an (N+2)th elastic slice stopped at the other end of the half side of the outer ring wall or the inner ring wall of the annular ring body, and N is larger than or equal to 1.

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...
