The first and second cone-pulley pairs each have a first cone pulley movable in an axial direction and a second cone pulley stationary in the axial direction. A flexible transmission means may be arranged between the first and second cone-pulley pairs for torque transmission. The first and second shafts may be rotatably supported by a bearing. The bearing of the first shaft or the second shaft may be a fixed bearing. The fixed bearing may include an inner bearing ring arranged on an outer circumferential surface of a corresponding shaft and an outer bearing ring fastened to a transmission housing by a sleeve extending through a wall of the transmission housing. ## Claims ### Claim 1 A cone-pulley flexible transmission, comprising: a first shaft having a first cone-pulley pair; a second shaft having a second cone-pulley pair, wherein the first and second cone-pulley pairs each have a first cone pulley movable in an axial direction and a second cone pulley stationary in the axial direction; a flexible transmission means arranged between the first and second cone-pulley pairs for torque transmission; wherein the first and second shafts are each rotatably supported by a bearing; wherein the bearing of the first shaft or the second shaft is a fixed bearing and includes: an inner bearing ring arranged on an outer circumferential surface of a corresponding shaft; an outer bearing ring fastened to a transmission housing by a sleeve, the sleeve extending through a wall of the transmission housing; wherein the sleeve is cylindrical in shape, at least in a first axial region, and has wall sections that are spaced apart in a circumferential direction; and wherein the wall sections extend through a wall of the transmission housing. ### Claim 2 (depends on 1) The cone-pulley flexible transmission of claim 1, wherein the sleeve extends in the axial direction over the outer bearing ring and surrounds the outer bearing ring in a radial direction on a first side facing away from the transmission housing. ### Claim 3 (depends on 1) The cone-pulley flexible transmission of claim 1, wherein the sleeve is formed integrally with the outer bearing ring. ### Claim 4 (depends on 1) The cone-pulley flexible transmission of claim 1, further comprising a cylindrical element arranged on an outer side of the wall of the transmission housing to support the wall sections of the sleeve in a radial direction. ### Claim 5 (depends on 1) The cone-pulley flexible transmission of claim 1, further comprising: a fixing element having a mating thread arranged on an outer side of the wall of the transmission housing; wherein the mating thread cooperates with a thread formed on the wall sections of the sleeve; and wherein the sleeve is fastened to the transmission housing by the fixing element. ### Claim 6 (depends on 5) The cone-pulley flexible transmission of claim 5, wherein the fixing element surrounds an outside of the wall sections in a radial direction and has an internal thread, and the wall sections have an external thread. ### Claim 7 (depends on 6) The cone-pulley flexible transmission of claim 6, wherein the fixing element has a sealing ring that forms a sealing surface running around in the circumferential direction with the outer side of the wall. ### Claim 8 (depends on 1) The cone-pulley flexible transmission of claim 1, wherein the transmission housing has a cylindrical flange extending into the transmission housing in the axial direction, wherein the outer bearing ring is supported in the axial direction on one end of the cylindrical flange. ### Claim 9 A cone-pulley flexible transmission, comprising: a shaft having a cone-pulley pair, the cone-pulley pair including a first cone pulley movable in an axial direction and a second cone pulley stationary in the axial direction; a bearing rotatably supporting the shaft, the bearing including an outer bearing ring fastened to a transmission housing, wherein the bearing is fixed in the axial direction; and a sleeve comprising wall sections spaced apart in a circumferential direction that extend through a wall of the transmission housing to fasten the outer bearing ring to the wall of the transmission housing. ### Claim 10 (depends on 9) The cone-pulley flexible transmission of claim 9, wherein the bearing further includes an inner bearing ring arranged on an outer circumferential surface of the shaft. ### Claim 11 (depends on 9) The cone-pulley flexible transmission of claim 9, wherein the sleeve is configured to extend in the axial direction over the outer bearing ring and surround the outer bearing ring in a radial direction on a first side of the bearing. ### Claim 12 (depends on 9) The cone-pulley flexible transmission of claim 9, wherein the sleeve is fastened to the transmission housing via a fixing element arranged on an outer side of the wall of the transmission. ### Claim 13 (depends on 9) The cone-pulley flexible transmission of claim 9, further comprising a flange extending into the transmission housing in the axial direction, wherein the outer bearing ring is supported in a fixed manner in the axial direction on one end of the flange.
