Embodiment Construction
[0011] specific implementation
[0012] Such as figure 1 As shown, the outer contour curve of the non-circular fully meshing shock wave disk is a curve tangent to the outer contour lines (circles) of all movable teeth that are equiangularly distributed on the cycloidal contour of the center wheel.
[0013] Such as figure 2 As shown, the outer contour of the non-circular fully meshing shock wave disc 2 is in contact with the outer contours of all movable teeth 4, that is, they are fully meshed. Due to the conjugation, the outer contour of the shock wave disk is in contact with the outer contours of all movable teeth during the movement, and the movable teeth are continuously driven.
[0014] Compared with the prior art, the present invention has the following positive effects: the hysteresis is small, and the service life of the bearing on the shock wave disk shaft is long.

The invention discloses a non-circular completely-conjugated shock wave disc which enables a cycloid oscillating tooth speed reducer to operate stably and accurately. The non-circular completely-conjugated shock wave disc takes a curve tangential to all oscillating tooth outlines as a shock wave disc outline; and due to conjugacy, all the outlines are tangential to oscillating teeth when the shock wave disc rotates, so that each oscillating tooth is continuously driven to move along a central outline. The non-circular completely-conjugated shock wave disc has the advantages that 1 the non-circular completely-conjugated shock wave disc is conjugated with all the oscillating teeth, radial pressure of a bearing on a shock wave disc shaft is balanced and the service life of the bearing is long; and 2 the non-circular completely-conjugated shock wave disc is conjugated with all the oscillating teeth so that the movement precision is improved.
Description
technical field [0001] The invention relates to a shock wave disk of a cycloid movable gear reducer; specifically, the invention replaces an eccentric circular shock wave disk or an elliptical shock wave disk with a non-circular fully meshing curve shock wave disk. Background technique [0002] At present, when the cycloid movable tooth reducer has one tooth difference, the outer contour of the shock wave disk is an eccentric circle (one peak); when the movable tooth reducer has two tooth differences, the outer contour of the shock wave disk is an ellipse (two peaks ). When the movable teeth are distributed equiangularly on the center wheel, the inscribed line is a corresponding non-circular curve (must not be a circle or an ellipse), and the existing shock wave disc can only mesh with part of the movable teeth. Its disadvantages are: the bearing on the shock wave disc shaft bears unbalanced radial force and is easily damaged; the meshing area is small and the hysteresis is...
