Rotation transmission device

Title:

Rotation transmission device

Document Type and Number:

Japanese Patent JP6159212

Kind Code:

B2

Abstract:

When a control retainer (16A) and a rotary retainer (16B) rotate relative to each other, a plurality of pairs of rollers (15) received in respective pockets (31) are pushed by pillars (25, 29) so as to move to their disengaged position. An anti-rotation means (60) is provided between an outer ring (11) and the control retainer (16A). The anti-rotation means (60) prevents the control retainer (16A) from rotating relative to the outer ring (11) when the rollers (15) are engaged, so that that the rollers (15) does not move to their neutral position. This increases reliability. The anti-rotation means (60) includes a plurality of first protrusions (61) formed on the surface of the outer ring (11), and a plurality of second protrusions (63) formed on the surface of the control retainer (16A) axially opposed to the surface of the outer ring (11). Heat treatment is performed to the first and second protrusions (61, 63) so as to increase the hardness thereof. Therefore, due to the impact generated when two of the second protrusions (63) collide with two of the first protrusions (61), respectively, the first and second protrusions (61, 63) are never damaged.
