A chain type pin wheel transmission device

Abstract

The invention relates to a chain-type pin wheel transmission device which comprises a chain-type pin wheel, a gear (1) and a guide device (4). The chain-type pin wheel is formed by at least 10 pin wheel units; the pin wheel units are sequentially connected in series; the pin wheel units which are connected in series and hinged are arranged along the guide device (4) to form the chain-type pin wheel; drive pins (201) which are fixed on the pin wheel units and are used for being meshed with the gear (1) are also particularly arranged in the chain-type pin wheel; the distances between each two drive pins (201) in the chai-type pin wheel are equal; and a multi-section movement pin tooth transmission structure is formed between the gear (1) and the chain-type pin wheel by the drive pins (201). According to the invention, a fixed mode that the pin wheel needs to move according to a round path is broken through, so that in the pin tooth driving process, the pin wheel can operate according to an oval path or a sealed or unsealed path formed by sequentially and smoothly connecting any one of combinations of curves and straight lines and a combination of curves. The chain-type pin wheel transmission device has foreseeable huge economic value and social value.

Description

technical field [0001] The invention relates to the technical field of transmission device structure design, and in particular provides a chain type pin wheel transmission device. Background technique [0002] So far, in pin-tooth transmissions at home and abroad, the pin wheels that cooperate with the gears have fixed structural shapes. Its shape is circular in the literature; driven by the gear, the pin wheel rotates in a fixed circular path. [0003] According to the editor-in-chief of Cheng Daxian, the third volume 14-555 of the fifth edition of the "Mechanical Design Manual" published by the Chemical Industry Press, the pin gear transmission belongs to a special form of gear transmission in the prior art, and the large gear with round pin teeth is called a pin wheel (circular one-piece rigid structural form), while another pinion with a general gear tooth profile is usually called a gear (see figure 1 , figure 2 ). [0004] Pin-tooth transmission has three transmis...

Problems solved by technology

[0007] Although the existing pin-tooth transmission has its advantages, the fixed mode of the pin wheel rotating in a circular path limits the scope of use of the pin-tooth transmission, especially in large-scale applications, because it can only run circular paths. The layout of the site is not conducive to the effective use of the site and the expansion of the transportation function

[0008] Although the chain transmission in the prior art can run a limited non-circular path, there are defects such as the range of the sprocket wrap angle should not be too small, heavy load and continuous long-term operation, and large transmission impact;
