Abstract

A transmission system comprising at least two wheels and a belt wound around the wheels with an unambiguous transmission ratio in that the transmission system is free from clearance and is comparatively stiff, while geometric errors, such as the polygon effect, and manufacturing errors and the occurrence of slip are neutralized in that the wheels are subdivided into segments, which can separately perform a tangential displacement. The belt has spaced opening for receiving the segments, which tangentially displace in case of misalignment of the segments to the belt openings. The belt has spaced opening for receiving the segments, which tangentially displace in case of misalignment of the segments to the belt openings.

Independent Claims | See all claims (17)

  1. 1. A transmission system comprising:a first wheel;a second wheel; andan endless belt wound about the wheels for driving one wheel in response to the rotation of the other wheel;each wheel being subdivided into a plurality of radially extending segments, each segment being secured for resilient tangential displacement relative to an adjoining segment, each segment having an outer peripheral running surface from which a radially directed projection extends, said belt having a plurality of recesses dimensioned to engage said projections, said running surface being dimensioned relative to said projection such that power is primarily transmitted to and from the belt by friction with the running surfaces.
  2. 17.17. A wheel for a transmission system having a pair of wheels and an endless belt wound about the wheels for driving one wheel in response to the rotation of the other wheel, said belt having a plurality of recesses, said wheel comprising:a plurality of radially extending segment; andmeans for securing each segment for resilient tangential displacement relative to an adjoining segment, each segment having an outer peripheral running surface from which a radially directed projection extends, said projection for engagement with a belt recess and dimensioned such that power is primarily transmitted to and from the belt by friction with the running surfaces.
