Gear　transmission　systems　are　one　of　the　most　frequently　used　systems　for　power　transmission.　The　characteristics　of　a　gear　transmission　system　have　important　guiding　significance　in　the　design,　manufacture　and　application　of　transmissions.　This　paper　focuses　on　the　influence　of　system　parameters　on　the　characteristics　of　a　specific　type　of　gear　transmission,　the　nutation　drive　with　double　circular　arc　spiral　bevel　gears.　Based　on　the　transmission　ratio　analysis　of　single-stage　and　two-stage　nutation　drive　systems,　the　system　parameters,　including　nutation　angle,　gear　spiral　angle,　pitch　angle　and　cone　distance,　were　defined.　An　analysis　of　the　influence　of　system　parameters　on　transmission　efficiency　was　performed.　Furthermore,　the　influence　of　system　parameters　on　axial　misalignment　and　cone　displacement　error　was　investigated.　Finally,　by　changing　the　input　frequency,　input　load,　nutation　angle,　and　spiral　angle,　variation　regularity　of　the　dynamic　meshing　force　was　obtained.　A　transmission　performance　analysis　based　on　the　influence　of　system　parameters　was　achieved　and　provides　the　theoretical　basis　for　better　design　of　the　nutation　drive　with　double　circular　arc　spiral　bevel　gear.
