Problems solved by technology

[0004] In view of the above problems, the present invention innovatively proposes a three-chord movable tooth transmission mechanism. Compared with the structure of the existing string-line movable tooth transmission, that is, the centerline of the tooth profile where the center of the movable tooth is located is two chord lines and a straight line, the three-chord The movable tooth transmission adopts a new structural form, that is, the center line of the tooth profile where the center of the movable tooth is located is three chord lines, and the movable tooth is also three parts, but its transmission principle is different from the existing string movable tooth transmission. It is more complicated than the calculation method, but when the reduction ratio is constant, the number of movable teeth of the single-stage mechanism is much larger than that of the existing string-line movable tooth transmission mechanism, which greatly improves the carrying capacity and makes the output Torque is more stable

Abstract

The invention discloses a three-string oscillating tooth transmission mechanism and a speed reducer thereof. The three-string oscillating tooth transmission mechanism comprises a driving shaft, a fixed string wheel, a shock wave string wheel, a movable string wheel and oscillating teeth; and tooth profile center lines where the centers of the oscillating teeth of the three-string oscillating tooth transmission mechanism are located are three strings, the multiple oscillating teeth are arranged among the string tooth profiles on the fixed string wheel, the shock wave string wheel and the movable string wheel, and the centers of the oscillating teeth are all arranged on the tooth profile center lines corresponding to the three string tooth profiles at the same time. The transmission principle of the three-string oscillating tooth transmission mechanism is different from that of existing string oscillating tooth transmission, and a reduction ratio calculation expression can be accurately determined; and under the condition that the reduction ratio is constant, the number of oscillating teeth of a single-stage mechanism is increased compared with the number of the oscillating teeth in an existing string oscillating tooth transmission mechanism, so that the bearing capacity is improved, and the output torque is more stable.

Description

technical field [0001] The invention relates to the technical field of movable tooth transmission, in particular to a three-chord movable tooth transmission mechanism and a reducer thereof, in particular to a single-stage three-chord movable tooth transmission mechanism, a double-stage three-chord movable tooth transmission mechanism, a two-stage A series reducer and a two-stage parallel reducer. Background technique [0002] There are many branches of movable tooth transmission, and the two commonly used ones are cycloidal movable tooth transmission and chord movable tooth transmission. The soul of these two transmission forms lies in the centerline of the tooth profile meshing with the movable tooth. At the same time, it moves in different tooth profile centerlines to complete the conversion of mechanism motion. The centerline of the tooth profile can be a cycloid, a chord, a straight line, or a line with a length of zero, that is, a point; for example, the patent No. 202...
