Abstract

The invention discloses a coaxial type gear rack high speed dividing mechanism, comprising a box body, an input shaft and an output shaft, wherein axial lines of the input shaft and the output shaft are on the same straight line; the input shaft is fixedly connected with a driving ring provided with at least one pair of radial through holes which are symmetrically arranged; the output shaft is fixedly connected with a gear, at least one rack push rod is meshed with the gear, the rack push rod consists of a rack and push rods arranged on both ends of the rack; the push rods pass through radial through holes on the driving ring respectively; end parts of the push rods are provided with rollers; the box body is fixedly connected with internal profile conjugate cam rollers contacting the rollers on end parts of the push rods respectively. The dividing mechanism of the invention is widely applied in automatic machines fields such as the printing, the packaging, the foods, the ceramics, the pharmacy and the military industry, etc., in which the wide range of number of divisions, the compact structure, the strong rigidity, the good bearing capacity, the common axis and the same rotation speed of the input and the output and high speed division intermittent movement are required.

Description

technical field [0001] The invention relates to an indexing mechanism, in particular to an indexing mechanism for realizing high-speed intermittent motion. Background technique [0002] Currently commonly used intermittent mechanism types are: cam indexing mechanism, ratchet, grooved wheel and incomplete gear mechanism, etc. As we all know, ratchet, sheave, and incomplete gear mechanisms can only be used in occasions that do not require high operating speed and indexing positioning accuracy due to their shortcomings such as low indexing accuracy and high impact noise. The cam-type indexing mechanism has been widely used in various automatic machines such as printing, textiles, medicine and food packaging, electronic component assembly, and military machinery due to its high speed and high precision. [0003] There are three types of commonly used indexing cam mechanisms, including arc surface indexing cam mechanisms, cylindrical indexing cam mechanisms and parallel indexing...
