Embodiment approach 1

[0056] Such as figure 1 , Figure 2-1 to Figure 2-8 As shown, the mechanism includes an input shaft 1, an input disc 5, an inner steel ball 6, an outer steel ball 7, a movable rack 8, a swing disc 9, a rotary disc 11, a rotary shaft 16, and a swing shaft 17. The input shaft 1 and the input disc 5 are fixedly connected to form a shock wave; the movable rack 8 is fixedly connected to the frame, and the inner steel balls 6 and outer steel balls 7 are evenly distributed on the movable rack 8 along the circumferential direction in the radial groove of the input disc 5 and the staggered area between the end profile groove of the input disc 5 and the end profile groove of the rotary disc 11 and the staggered area between the input disc 5 end profile groove and the oscillating disc 9 end profile groove; the rotary disc 11. The oscillating disk 9 is fixedly connected with the rotating shaft 16 and the oscillating shaft 17 provided with flat keys respectively. The shock wave is suppor...

Embodiment approach 2

[0060] This embodiment is the same as Embodiment 1 in terms of the transmission principle of the mechanism, and the difference is that the swing law of Embodiment 2 is a trapezoidal curve without stop correction. The outline of the component is Figure 3-2 to Figure 3-5 shown.

Embodiment approach 3

[0062] This embodiment is the same as Embodiment 1 in terms of the transmission principle of the mechanism, except that the swing angle of Embodiment 3 is 30°. The outline of the component is Figure 4-2 to Figure 4-5 shown.

Abstract

The invention relates to a uniaxial-uniform-speed-input-coaxial-output rotation and pendulum motion oscillating-tooth cam mechanism, belonging to the field of machinery. The mechanism comprises an input shaft, an input disk, inner and outer layer steel balls, an oscillating tooth rack, a rotary disk, a pendulum disk, a rotating shaft, a pendulum shaft and a machine frame, wherein the input shaft and input disk are fixedly connected and integrated to constitute a shock wave device; the oscillating tooth rack is fixedly connected to the machine frame; the inner and outer layer steel balls are respectively uniformly distributed in inner and outer layer radial slots which are distributed in the circumferential direction on the oscillating tooth rack, and always respectively positioned in a staggered region of the input disk contrate tooth outline slot, rotary disk and pendulum disk contrate tooth outline slot; and the rotary disk and pendulum disk are respectively fixedly connected with the rotating shaft and pendulum shaft. The mechanism implements uniaxial uniform-speed input and simultaneously outputs rotation and pendulum motions; and the transmission ratio, the rotation direction of the rotating shaft, and the initial pendulum direction, pendulum angle, pendulum rules and carrying capacity of the pendulum shaft can be combined according to practical application, thereby achieving the goal of outputting multiple motions by a single device and widening the application range of the mechanism.

Description

technical field [0001] The invention relates to a movable-tooth cam mechanism with single-axis uniform-speed input and coaxial output rotation and swing motion, belonging to the technical field of mechanical transmission. Background technique [0002] At present, the motion output by a single mechanism is mostly a single type such as rotary motion or swing motion. With the continuous improvement of the performance of textile machinery, printing machinery, agricultural machinery and automated office equipment, the demand for motion types has become more and more diverse, and the existing equipment with a single output motion type is gradually unable to meet the needs of modern industries. Therefore, it is particularly important to design a mechanism that can simultaneously output a uniform motion with a strong load-carrying capacity and a wide range of transmission ratios and an oscillating motion with a large range of swing angles and high transmission precision.
