摘要： PROBLEM TO BE SOLVED: To provide a toroidal continuously variable transmission preventing a reduction in pressing force of a disk on a side separated from a pressing device against a power roller caused by frictional force between a trunnion and an outer ring. SOLUTION: The trunnion 15 is formed with a pair of guide surfaces 45, 45 juxtaposed along the direction of a pivot 14, opposed to each other in order to sandwich the outer ring 28, and also opposed to the peripheral surface of the outer ring 28. The guide surfaces 45, 45 are brought into contact with the peripheral surface of the outer ring 28 to thereby support tangential force acting on the power roller 11, and also guide the outer ring 28 along the direction of the rotating center shaft of each of the discs 2, 3. The pair of guide surfaces 45, 45 is inclined to the direction of the rotating center shaft of each of the discs 2, 3 so that a clearance between the pair of guide surfaces is increased toward the end side of the pressing force acting direction of the pressing device 12.

摘要： PROBLEM TO BE SOLVED: To provide a structure capable of reducing a torque loss of a thrust ball bearing by reducing an agitating resistance with a lubricating oil. SOLUTION: In a toroidal continuously variable transmission, the wall thickness of a subject 11a forming a retainer 10a is greater than that of an inner peripheral edge part 18a of the subject 11a at an outer peripheral edge part 19a. The sum (b in +b out =W o ) of the axial thickness of a clearance formed in the outer peripheral edge part 19a of the subject 11a is set greater than the sum (a in +a out =W i ) of the axial thickness of the clearance formed in the inner peripheral edge part 18a (W o >W i ). Thereby, the rotation resistance is easily increased due to the increased size of rotation radius, so that the rotation resistance acting between the outer peripheral edge part 19a and both the outer diameter side shoulders 20b, 21b is suppressed smaller.

摘要： PROBLEM TO BE SOLVED: To provide a toroidal type continuously variable transmission capable of avoiding drop of lifetime accompanying poor backup by preventing insufficient backup of a power roller by a bearing accompanying oscillation of the power roller around a support shaft.
SOLUTION: In this toroidal type continuously variable transmission, a thrust needle bearing 25 allowing oscillation of the power roller 11 and an outer ring 28 around a displacement shaft 23 is fitted and retained in the outer ring 28. Therefore, the thrust needle bearing 25 also moves together with the power roller 11 when the power roller 11 oscillates around the displacement shaft 23 and keeps offset against a trunnion 15 to transmit pressing force from an input side disk 2 to an output side disk 3. Consequently, a backup condition of the thrust needle bearing 25 against a raceway surface of a thrust ball bearing 24 does not change.

摘要翻译：要解决的问题：提供一种环形无级变速器，其能够通过防止由于支撑轴周围的动力辊的振荡的轴承而使动力辊的不充分的备用而避免由于备用不良引起的寿命的下降。解决方案：在这种环形无级变速器中，允许动力辊11和位于容置轴23周围的外圈28摆动的推力滚针轴承25被装配并保持在外圈28中。因此，推力针当动力辊11围绕位移轴23摆动时，轴承25也与动力辊11一起移动，并且保持抵靠耳轴15偏移，以将压力从输入侧盘2传递到输出侧盘3.因此，备用条件推力滚针轴承25抵靠推力球轴承24的滚道面不发生变化。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a troidal-type continuously variable transmission excellent in workability capable of smoothly conducting the rolling guide of a power roller with an outer ring for a trunnion with small abrasion resistance without using a displacement shaft for a shaft part for supporting the power roller by using an inexpensive and simple structure.
SOLUTION: A pair of guide faces facing each other, extending vertical to a rotation center shaft of the power roller 11 and vertical to a pivot 14 are provided at the trunnion 15. An outer ring body (outer ring) 28a of a thrust ball bearing 24 for rotatably supporting the power roller is provided between the pair of guide faces. An annular rotation member 120b is rotatable along the outer circumference of the outer ring body by a radial bearing 120 provided at the outer circumference of the outer ring body. When the outer ring body moves together with the power roller in the above direction, in the case that the rotation member contacts with either of the pair of guide faces, the rotation member contacts with the guide face and rolls.

摘要： PROBLEM TO BE SOLVED: To realize a structure capable of threading and tightening a trunnion 4 with a rod 8 even if the supporting strength of the support portions of support plates 16 and 16 and a casing is not so high.
SOLUTION: The threading directions of both male and female screw parts 24 and 25 of multiple sets of trunnions 4 and rods 8 supported on the same support plates 16 and 16 are reversed to each other. In assembling, both the male and female parts 24 and 25 of the multiple sets of trunnions 4 and rods 8 having threading directions reversed to each other are simultaneously threaded and tightened with each other. By this configuration, forces based on tightening forces applied to the support plates 16 and 16 can be offset each other.

摘要： PROBLEM TO BE SOLVED: To dispense with forming a supply/discharge hole in an input shaft 5 to supply/discharge pressurized oil into the hydraulic pressure chamber 38 of a pressing device 37, reduce size and weight by preventing the diameter of the input shaft 5 from becoming large, and reduce cost.
SOLUTION: The supply/discharge of the pressurized oil into and from the hydraulic pressure chamber 38 are performed through an oil passage 49 formed in a support post 17a for supporting an output side disk 9. Since the support post 17a does not receive a large force, it must not be increased in size by forming the oil passage 49 therein. The hole for supplying/discharging the pressurized oil into and from the hydraulic pressure chamber 38 must not be formed in the input shaft 5 receiving a large force.

摘要： PROBLEM TO BE SOLVED: To prevent fretting abrasion between outside surface of an input side disk 4b and one side surface of a first connecting plate 43a and to prevent a transmission efficiency of a planetary gear type transmission 2b from being deteriorated if required. SOLUTION: The stepless transmission is configured to abuts one side surface of the first connecting plate 43a and outside surface of the input side disk 4b with respect to radial directions of the first connecting plate 43a and the input side disk 4b on inner diameter side and simultaneously to oppose them via clearance on outer diameter side as well. Thereby, an elastic deformation of the input side disk 4b is hard to transmit to the first connecting plate 43a. In addition, both of the side surfaces between one another abut only with a portion of low rigidity in axial direction of a carrier 7a, and form film for preventing abrasion on both of the side surfaces, and form a recess for storing lubricant.
