Embodiment Construction

[0012] attached figure 1 , 2 Shown is a preferred embodiment of the present invention. In this embodiment, the space oscillating cam stage speed change transmission device of the present invention comprises a frame 11, an input shaft 4, an output shaft 9, a gear train composed of gears 7 and 8, an overrunning clutch 10, a space cam 5, a speed regulating The mechanism, the slide plate 3, the input shaft 4 and the output shaft 9 are respectively rotatably installed on the frame, and the two shafts are on the same axis. The space cam is fixed on the input shaft 4, and the space cam has the same base circle in the axial direction, and the swing stroke of the space cam increases monotonously from zero to one side of the frame axially (such as Figure 4 shown), the cross-sectional profile of the space cam is designed according to the rule that the thrust motion is a constant speed motion (such as Figure 5 As shown), a slide plate 3 is set on the outer edge of the space cam, and ...

Abstract

The invention provides a spatial swing type stepless pulse transmission, and is characterized in that a main body structure is as follows: an input shaft and an output shaft are coaxially arranged on a frame, a space cam is fixed on the input shaft, the space cam is provided with the same base circle in an axial direction, a swing travel of the space cam is monotonously increased from zero to one side of the frame along an axial direction, and a section outline of the space cam is designed according to a rule that the rise travel movement is uniform movement; the outer edge of the space cam is sheathed with a sliding plate, a plurality of swing rods are uniformly distributed on the outer periphery of the sliding plate, one ends of the swing rods are butted to the space cam for pressing, the other ends of the swing rods are respectively connected with a rotating shaft, wherein the right side of the rotating shaft is connected with an inner ring of an overrunning clutch, an outer ring of the overrunning clutch is respectively connected with a gear, and each gear is engaged with a driven gear on the output shaft; and a speed regulating mechanism and the sliding plate are in transmission connection. According to the invention, the variable-speed drive at zero pulse degree is realized, and the spatial swing cam type stepless variable drive has the advantages of simple and compact structure and wide speed change range.

Description

technical field [0001] The invention relates to a space oscillating cam stepless transmission device, which adopts a cam mechanism with high pair contact, and can be used in many occasions requiring stepless transmission with medium and low loads, such as printing machinery and light industrial machinery. Background technique [0002] The existing pulsating continuously variable transmission device has many schemes, among which the closest prior art to the present invention is the Chinese patent No. ZL 200510132747.3, which discloses an eccentric cam type pulsating continuously variable transmission, which relies on Eccentric cams, swing levers and overrunning clutches realize pulsating continuously variable transmission. The transmission realizes stepless transmission according to the eccentricity of the eccentric cam. The larger the eccentricity, the larger the transmission ratio, and can realize the transmission with zero transmission ratio. Multiple groups are used to al...
