    摘要： A chain guide and a chain tensioner device using the chain guide. A roller, brought into contact with a chain, comprises a support shaft supported by an opposing guide base provided along the running direction of the chain, and roller bearings each having a steel outer ring on the outer peripheral surface of the support shaft so as to be brought into contact with the chain. The roller is also configured to be assembled by inserting opposite ends of the support shaft into support recesses on facing wall surfaces of the guide base. The roller has a vibration damping material between the support shaft and the support recess of each of the plate members.

    摘要： An object of the present invention is to provide a chain guide which has low noise and low vibration even when being brought into contact with a chain running at high speed, and to provide a chain tensioner device using the chain guide. A chain guide base provided along the running direction of a chain is integrally attached to a tensioner plunger that presses the chain guide base against the chain side so as to increase the weight of the chain guide itself to reduce vibration.

    摘要： A positioning protrusion 14 is provided in a center of an outer diameter surface of a halved outer ring 11a in both circumferential and axial directions. The positioning protrusion 14 is configured to engage with a housing, which is placed on an outer diameter side of the halved outer ring, to position the halved outer ring 11a with respect to the housing. A protruding portion 17a and a recessed portion 17b are provided in each abutting portions 16a, 16b where a pair of the halved outer rings 11a abut on each other when fitted on a rotary shaft that is supported by a roller bearing. The protruding portion 17a and the recessed portion 17b are configured to mesh with each other to restrict axial movement of both halved outer rings 11a. The protruding portion 17a and the recessed portion 17b are point-symmetric with respect to a center 20 of the positioning protrusion 14.

    摘要： Provided are a gear and a gear drive unit which allow oil film formation to a sufficient degree between tooth surfaces of gears rotating at high-speed and which help to prevent generation of pitting, abrasion, and prevent scoring, temperature rise, and wear to thereby achieve an improvement in terms of durability. A tooth surface is provided with a multitude of minute recesses arranged at random, in which an axial surface roughness parameter Ryni of the surface thus provided with the recesses is set to a range: 0.8 μm≦Ryni≦2.3 μm. As a result, the tooth surface is endowed with a high oil film formation performance, and it is possible to attain a long service life even under a low-viscosity/thin-lubrication condition in which the oil film is extremely thin.
