Embodiment 1

[0043] Such as figure 1 As shown, an 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.

[0044] The elastic structure includes two shrapnel groups symmetrical to each other, and each shrapnel group includes a number of shrapnels 21 distributed on the outer ring wall or half of the inner ring wall of the annular ring.

[0045] The annular ring body is correspondingly provided with a thickened area 22; the thickened area is located on the outer ring wall or the inner ring wall of the annular ring to form a corresponding arc surface; the thickened area is located on the inner ring of the annular ring The wall forms the inner horizontal line of the circle, and the outer ring wall of the annular circle forms the outer arc line of the circle.

[0046] Each shrapnel group includes a first shrapnel starting from one end of the outer ring wall of the annular ring or one half of t...

Embodiment 2

[0069] Such as figure 2 As shown, an 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.

[0070] In this embodiment, the elastic structure includes an elastic limiting boss 23 and shrapnel groups distributed symmetrically along both sides of the elastic limiting boss, and each shrapnel group includes a number of first shrapnel distributed on the outer ring wall of the annular ring Grouping and second shrapnel grouping, the first shrapnel grouping and the outer ring wall of the annular ring form an angle that is biased toward the elastic limit boss, and the second shrapnel grouping and the outer ring wall of the annular ring form a reverse elastic limiting The included angle of the boss.

[0071] Each shrapnel grouping includes the first shrapnel starting from the middle section of the half side of the outer ring wall of the annular ring, N middle shrapnel and the N+2th...

Embodiment 3

[0094] This embodiment discloses an extrusion-type deformation ring. The extrusion-type deformation ring includes an annular ring body. One of the differences between this embodiment and Embodiment 1 is that the inner ring wall of the annular ring body is provided with Elastic structure.

[0095] The 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.

[0096] Each shrapnel group includes a first shrapnel starting from one half of the outer ring wall or the inner ring wall of the annular ring, two middle shrapnels and a fourth shrapnel ending at the other end of the inner ring wall half of the ring ring.

[0097] The root of each shrapnel is integrally connected with the outer ring wall or the inner ring wall of the annular ring, and the tail of each shrapnel forms an included angle with the inner ring wall of the annular rin...

Abstract

The invention discloses an extrusion type deformation ring which comprises an annular ring body. The outer ring wall and/or the inner ring wall of the annular ring body are/is provided with an elasticstructural member. The elastic structural member comprises two mutually symmetrical elastic piece groups, and each elastic piece group comprises a plurality of elastic pieces distributed on the halfside of the outer ring wall or the inner ring wall of the annular ring body; or the elastic structural member comprises an elastic limit boss and elastic piece groups symmetrically distributed along the two sides of the elastic limit boss, each elastic piece group comprises a plurality of first elastic piece sub-groups and second elastic piece sub-groups distributed on the outer ring wall or the inner ring wall of the annular ring body, the first elastic piece sub-groups and the outer ring wall or the inner ring wall of the annular ring body form included angles toward the elastic limit boss,and the second elastic piece sub-groups and the outer ring wall or the inner ring wall of the annular ring body form included angles opposite to the elastic limit boss. The extrusion type deformationring is applied to an elastic speed reducer, can effectively avoid errors and eliminate abnormal vibration waves, has high precision and rigidity, and enables the elastic speed reducer to be simplified in structure and to be easy to process and produce.

Description

technical field [0001] The invention relates to the technical field of elastic reducers, in particular to an extrusion-type deformation ring. 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, t...
