Document Type and Number:
WIPO Patent Application WO/2015/156705
Kind Code:
A3
Abstract:
The present invention relates to a roller reducer comprising a transmission gear having an externally threaded shaft having at least one left-handed thread portion, at least one right-handed thread portion, and at least one shaft flange ring, and a plurality of rollers, each roller having a plurality of thread portions, comprising at least one left-handed thread portion and at least one right-handed thread portion, each thread portion arranged to engage with the respective thread portions of the shaft, and at least one roller flange ring arranged adjacent to the roller thread portions to rotationally slide against the corresponding at least one flange ring of the shaft. Diameters of the flange rings of the rollers and the flange rings of the shaft are each equal to the respective effective thread diameters of the engaged thread portions of the rollers and the shaft, respectively. Advantageously, the inventive roller gear eliminates, at least in part, bending of the rollers and the threaded shaft, lessens slip while increasing efficiency of the reducer.
