This planetary roller type power transmission device includes an input shaft 1 made of a round bar, and a plurality of (for example, 4) arranged on the outer peripheral surface of the input shaft 1 at equal intervals around the circumference.
Individual carrier rollers 3 and a plurality of carrier pockets 3a (equal to the number of planet rollers) provided in the cylindrical portion at equal intervals around the circumference of the carrier 3 for rotatably holding the planet rollers 2 respectively.
And a fixed ring 4 concentrically fixed to the input shaft 1 and interposing each planetary roller 2 in a rolling frictional contact state with the input shaft 1. When the input shaft 1 rotates, The planetary roller 2 rotates and revolves due to the rolling frictional contact with the input shaft 1, whereby the carrier 3 rotates at the revolution speed of the planetary roller 2 due to the sliding contact with the planetary roller 2.

５の間の摩擦損失が増大し、ひどい場合には作動が困難
となる。Most of the power loss of the planetary roller type power transmission device in which the planetary roller 2 and the carrier 3 shown in FIG. 6 make sliding contact is due to the contact between the planetary roller 2 and the carrier 3. . Therefore, the temperature of the planetary roller 2 rises more easily than that of the fixed ring 4, and the planetary roller 2
And a difference occurs in the thermal expansion of the fixed ring 4. However, since the clearance H between the planetary roller 2 and the side plate 5 is the difference in width between the fixed ring 4 and the planetary roller 2, if the clearance H between the planetary roller 2 and the side plate 5 is too small, the clearance between the planetary roller 2 and When a difference occurs in the thermal expansion of the fixed wheel 4, the clearance H between the planetary roller 2 and the side plate 5 becomes negative. As a result, the friction loss between the side surface of the planetary roller 2 and the side plate 5 increases, and in severe cases, the operation becomes difficult.

It is necessary to secure a certain clearance H between them. However, when a certain clearance H is secured between the planet roller 2 and the side plate 5, the clearance H allows the planet roller 2 to move.
Skew is possible. When the skew of the planetary roller 2 becomes large, the axial force acting on the planetary roller 2 becomes large, the surface pressure between the planetary roller 2 and the side plate 5 rises, and the heat generated between the planetary roller 2 and the side plate 5 increases. Will increase.

る。Further, the side plate has good friction and wear characteristics,
Plating or solid lubricant coating with a hardness lower than that of the planetary roller was applied, and this plating or solid lubricant coating was used to reduce the friction coefficient at the contact area between the side surface of the planetary roller and the side plate. By suppressing heat generation at the contact portion, it is possible to prevent a decrease in transmission efficiency and a large abrasion or damage to the side surface or side plate of the planetary roller.
【００３７】さらに、側板にショットピーニングを施
