Embodiment Construction

[0012] The drawings show a preferred embodiment of the present invention. In this embodiment, the coaxial cam continuously variable pulse transmission of the present invention includes a housing, an input shaft 1, an output shaft 11, a gear train composed of a pinion 8 and an internal gear 9, an overrunning clutch 5, and a cam 2 and a set of speed ratio adjustment components, the input shaft 1 and the output shaft 11 are respectively rotatably mounted on the housing, and the two shafts are on the same straight line. The cam 2 is fixed on the input shaft 1. In this embodiment, the cam 2 is an oblique cylindrical cam. A slip ring 3 is fitted on the outer edge of the cam. In this embodiment, the slip ring 3 is sleeved on the side surface of the inclined cylinder of the cam, and the center hole of the slip ring 3 matches the shape of the side surface of the inclined cylinder. That is, the central hole is an inclined hole with the same inclination as the inclined cylinder.

Abstract

The invention includes a casing, an input shaft, an output shaft, a gear train, an overdrive clutch, a cam and a set of speed ratio regulating assemblies. The input shaft and the output shaft are mounted on the casing separately, and on the input shaft is fixed a cam. On the other edge of the cam is interlinked a slip-ring, and the axial relative position of the cam and the slip-ring can be regulated to change the gear ratio. The periphery of the slip-ring is inserted inside the groove of a swing link, and the number of the swing link is different according to the need of the pulsing amplitude. The internal ring of each overdrive clutch and a pinion are mounted in the same sleeve outside the arbor. Each pinion is engaged with a common internal gear coaxial connected firmly with the output shaft.

Description

Technical field [0001] The invention relates to a coaxial continuously variable pulsating transmission, which can be used in many occasions requiring continuously variable transmission, such as mechanical equipment in textile machinery, printing machinery, light industry machinery and other industries. Background technique [0002] The coaxial continuously variable pulsation transmission has many technical solutions in the prior art, and the prior art closest to the present invention is represented by the Chinese patent CN89201734.1. This patent discloses a pendulum-type pulsating mechanical continuously variable transmission, which realizes a pulsating continuously variable gear transmission by means of an eccentric disc and an overrunning clutch. This kind of transmission overcomes the problems that the stroke speed ratio coefficient of the main mechanism changes with the change of the frame or crank length during speed regulation, the pulsation curve of the output shaft speed ...
