摘要： PROBLEM TO BE SOLVED: To provide a power transmission device to perform power transmission through a rolling contact of a troidal type CVT (a transmission with continuously variable gear ratio) whereby the area in the neighbourhood of the contacting point can be cooled efficiently.
SOLUTION: The power transmission device includes a roller 16 which makes rolling contact both with an input and an output discs for performing power transmission between the two discs. The surface 22 of the roller 16 confronting the two discs includes an abutting part 24 as an area actually contacting with the discs and an adjacent part 26 adjoining the abutting part 24 and not contacting with the discs. The adjacent part 26 is furnished with grooves 28 stretching from near the abutting part 24 in the direction going apart therefrom. Along the grooves the lubricating oil near the abutting part 24 is exhausted, which assures an increase in the circulating amount of the lubricating oil and allows efficient performance of cooling with the lubricating oil.

摘要： PROBLEM TO BE SOLVED: To provide a processing method of a rolling member capable of providing the toroidal type continuously variable transmission of long service life.
SOLUTION: This processing method comprises a plastic forming process for plastically forming a rolling part of the rolling member by actually operating the whole gear change range by not less than one time by changing an inclination angle of a gear change roller while applying the pressing load corresponding to the processing stress of more than 1.1 times of the elastic limit hertz stress and not more than shake-down limit of a metallic material composing the rolling part of the rolling member between the input disc and the output disc holding the gear change roller, in a state that input discs 11, 12, output discs 21, 22 and gear change rollers 31, 32 are assembled. Whereby the rolling part of the rolling member increases its resistance to deformation by being hardened in processing and is imparted with compression residual stress, and its fatigue strength increases.

The method for manufacturing the member comprises a precipitation step for precipitating fine precipitates, a normalizing step for controlling Vickers hardness to 250-350, and a surface layer hardening step for controlling the Vickers hardness of the surface layer in a range from the surface receiving high bearing pressure to at least 1.5 times deeper part than the distance between the surface and a portion of producing the maximum shearing stress amplitude, to 700-850. The member can be applied to an input disc 1, an output disc 2, and a driving roll 3 of a toroidal continuously variable transmission. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a power transmission device to perform power transmission through a rolling contact of a troidal type CVT (a transmission with continuously variable gear ratio) in which the durability is enhanced.
SOLUTION: The power transmission device includes a roller 16 which makes rolling contact both with an input and an output discs for performing power transmission between the two discs. The surface 22 of the roller 16 confronting the two discs has a contacting part 26 which contacts actually with the input and output discs for performing power transmission. The width B of the surface 24 exceeds three times as large as the width 2b of the contacting part 26. This lessens the influence of the end face upon the internal shearing stress generated in the neighnourhodd of the contacting part to drop the stress. This drop of the stress lessens the amount of heat emission. The heat capacity of the roller 16 can be made greater by enlarging the width B of the confronting surface, and also the area of heat emission is widened. The drop of stress and the drop in temperature result in enhancement of the durability.

摘要翻译：要解决的问题：提供一种动力传递装置，通过具有耐久性提高的齿轮式CVT（无级变速器的变速器）的滚动接触进行动力传递。解决方案：动力传递装置包括一个与输入和两个盘之间进行动力传递的输出盘滚动接触的辊16。面对两个盘的辊16的表面22具有接触部26，该接触部实际上与用于进行动力传递的输入和输出盘接触。表面24的宽度B超过接触部分26的宽度2b的三倍。这减小了端面对接触部分的相邻部分产生的内部剪切应力的影响，以降低应力。这种应力的下降会减少散热量。通过扩大相对表面的宽度B，能够使辊16的热容变大，并且散热面积也扩大。应力的下降和温度的降低导致耐久性的提高。

摘要： PROBLEM TO BE SOLVED: To increase torque that can be outputted from a power transmitter without causing the upsizing of the power transmitter.
SOLUTION: A motor 60 assembled with a rotor 62 is arranged at a ring roller 22 that operates together with an input shaft 16 at a rotation speed lower than that of the input shaft 16. A planetary roller mechanism 12 can transmit power generated by the rotor 62 of the motor 60 to an output shaft 18 by synchronizing the power with power from a motor 10 that is decelerated and transmitted to each pinion roller 23 from a sun roller 21 by the pinion roller 23. By this, the torque that can be outputted from the planetary roller mechanism 12 can be increased without increasing the torque transmission capacity of the planetary roller mechanism 12.

摘要： PROBLEM TO BE SOLVED: To provide a planetary roller mechanism capable of preventing macro slip properly without increasing normal force into a contact part excessively.
SOLUTION: Since a recessed part 26 is formed at a position opposing to an outer peripheral face 33 of a pinion roller 23 on an inner peripheral face 32 of a ring roller 22, length Lr (=L1+L2) of the contact part 28 of each pinion roller 23 and the ring roller 22 in the direction vertical to the direction of tangential line and the direction of normal line of the contact part 28 is set to be shorter than length Ls of the contact part 27 of a sun roller 21 and each pinion roller 23 in the direction vertical to the direction of tangential line and the direction of normal line of the contact part 27. Consequently, an area of the contact part 28 can be reduced, a surface pressure of the contact part 28 can be increased, and difference between the surface pressure of the contact part 27 and the surface pressure of the contact part 28 can be reduced.
