无级变速器
Abstract:
无级变速器具备：由轴（50）上的第一及第二旋转构件（10、20）夹持的多个行星球（40）；使各行星球（40）偏转的限制板（80）及蜗杆（81）；具备第一太阳辊（31）和第二太阳辊（32）的太阳辊（30），第一太阳辊具备具有与行星球（40）接触的第一接触点（P1）的第一筒状部（31a）及外径小于第一筒状部（31a）的外径的第二筒状部（31b），能相对于轴（50）相对旋转，第二太阳辊具有与行星球（40）接触的第二接触点（P2），能在第二筒状部（31b）的外周面上相对于第一太阳辊（31）相对旋转；及推力轴承（TB），该推力轴承配置在第一太阳辊（31）和第二太阳辊（32）之间，承接从行星球（40）传递至第一太阳辊（31）及第二太阳辊（32）的轴线方向的推力负荷。
Abstract(English):

The present invention comprises a plurality of planet balls (40) sandwiched between first and second rotating members (10, 20) on a shaft (50); an iris plate (80) and a worm gear (81) spinning each of the planet balls (40) at a slope; a sun roller (30) comprising a first sun roller (31) which includes a first cylindrical portion (31a) that has a first contact point (P1) with the planet ball (40) and a second cylindrical portion (31b) that has a smaller outer diameter than the first cylindrical portion (31a) to be capable of relative rotation with the shaft (50), the sun roller (30) also comprising a second sun roller (32) which includes a second contact point (P2) with the planet ball (40) to be capable of relative rotation with the first sun roller (31) on an outer circumferential surface of the second cylindrical portion (31b); and a thrust bearing (TB) disposed between the first sun roller (31) and the second sun roller (32) to receive a thrust load in a shaft line direction transmitted from the planet ball (40) to the first sun roller (31) and the second sun roller (32).
