1. Patentansprak: 1:o) Utvaxlingsanordning med foranderligt utvaxlingsfOrhillande, bestiende av en planetvaxel, som bar vilka som heist tvd av sina element forbundna genom en variationsvaxel, bestaende av en primar, konisk Tulle och en eller flera sekundara, koniska rullar saint ett mellan den fOrstnamnda och den eller de sistnamnda koniska rullarna anbragt rorligt averfOringsorgan, kannetecknacl darav, att kamanordningar (23, 24 eller 35, 36) Oro inrattad.e att under inverkan ay drivkraften automatiskt Ova ett axialtryck pa en eller flora av de koniska rullarna for att halla den primara och den eller de sekundara koniska rullarna samt overforingsorganet eller -organen i intim drivande beroring med varandra. 2:o) Utvaxlingsanordning enligt patentanspraket 1:o), kannetecknad darav, att de sekundara rullarna uppbaras av lampliga lager (44) och aro forsedda med profilerade delar (42, 46) omgivna a svavande friktionsringar (45, 47), vilkas insidor an) profilerade for samverkan med de profilerade delarna av rullarna. 3:o) Utvaxlingsanordning enligt patentansprilret 1:o), kannetecknad ddrav, att, da. planetvaxeln är utformad som friktionsvaxel, denna och kamanordningarna for utovande av axialtrycket aro sa:inrattade, att reaktionen av axialtrycket pa. rullen eller rullarna i variationsvaxeln verkar till forstarkning av friktionsingreppet mellan elementen i planetfriktionsvaxeln. (Hartill en ritning.) Stockholm 1930. Kungl. Boktryckerlet 21 oktober 1930. 4(30008() Generalstabens Lito1. Patent claim: 1: o) Gear unit with variable gear ratio, consisting of a planetary gear, which carried which heist tvd of its elements connected by a variation shaft, consisting of a primary, conical Tulle and one or more secondary, conical rollers saint one between the former and the latter or the latter conical rollers are provided with movable transfer means, characterized in that cam devices (23, 24 or 35, 36) are arranged to, under the influence of the driving force, automatically exert an axial pressure on one or more of the conical rollers in order to keeping the primary and secondary conical roller (s) and the transfer member or members in intimate driving contact with each other. 2: o) Gear unit according to claim 1: o), characterized in that the secondary rollers are supported by lamp bearings (44) and are provided with profiled parts (42, 46) surrounded by floating friction rings (45, 47), the insides of which ) profiled for interaction with the profiled parts of the rollers. 3: o) Gear unit according to patent application 1: o), can be drawn ddrav, att, da. the planetary shaft is designed as a friction shaft, this and the cam devices for exerting the axial pressure are so arranged that the reaction of the axial pressure pa. the roller or rollers in the shaft of variation acts to reinforce the frictional engagement between the elements of the planetary shaft of friction.
