Problems solved by technology

[0007] Next, see Figure 12 , 13 In the JPA-2012251603 diagram shown, the outer contour of the wave generating wheel 14 uses three circular arcs to simulate an ellipse, but because it uses three circular arcs, the α angle of the part of which the radius of the arc is R1 is only 5 degrees, so the strength of the wave generating wheel is limited

Embodiment Construction

[0066] refer to Figure 14A As shown, the harmonic reduction mechanism provided by the first embodiment of the present invention is mainly composed of a rigid internal gear 20, a flexible external gear 30, a flexible bearing 40, and a wave generating wheel 50. composed of:

[0067] The rigid internal gear 20 is hollow, with a number of teeth of 2 (n+1) and a modulus of m; in this embodiment, each tooth shape of the rigid internal gear 20 is an involute tooth shape.

[0068] The flexible external gear 30 is hollow, pierced through the rigid internal gear 20, and is provided with a number of teeth of 2n and a modulus m that is the same as the modulus m of the rigid internal gear 20; in this embodiment, Each tooth profile of the flexible external gear 30 is an involute tooth profile, and the tooth profiles of the flexible external gear 30 and the rigid internal gear 20 are the same in the effective area. The part where the gear 30 and the rigid internal gear 20 mesh and drive e...

Abstract

The invention discloses a harmonic type reducing mechanism. The harmonic type reducing mechanism comprises an inner rigid gear with a tooth number of 2(n+1), an outer flexible gear with the tooth number of 2n, a flexible bearing and a wave generation wheel, wherein the outer flexible gear is arranged in the inner rigid gear in a penetrating manner, and the outer flexible gear has a modulus m which is identical to that of the inner rigid gear; the flexible bearing is arranged in the flexible outer bearing in a penetrating manner; the wave generation wheel is arranged in the flexible bearing in a penetrating manner. By increasing the meshed gear teeth, so that a pitch error of each tooth is reduced by average, the transmission precision is improved, the transmission torque is increased, and the flexible bearing is ensured to rotate smoothly.

Description

technical field [0001] The invention relates to a deceleration mechanism, in particular to a harmonic deceleration mechanism. Background technique [0002] refer to figure 1 As shown, a diagram showing a harmonic reduction mechanism of US7178427B includes a rigid internal gear 11, a flexible external gear 12 passing through the rigid internal gear 11, and a flexible external gear 12 passing through the flexible external gear 12. Flexible bearing 13, and a wave generating wheel 14 passing through the flexible bearing 13, when the wave generating wheel 14 rotates, it pushes the flexible bearing 13 and the flexible external gear 12 to deform to drive the flexible external gear The meshing teeth at different positions of 12 mesh with the corresponding meshing teeth of the rigid internal gear 11 sequentially, and a reduction transmission effect is generated by the designed tooth number difference between the rigid internal gear 11 and the flexible external gear 12 . [0003] Ho...
