摘要: It is aimed to prolong the life of a rocker arm in which rollers are housed in a full type form between a ring and a pin from a viewpoint completely different from the idea of improving the material. It is proposed to suitably control the relation between clearances in circumferential and radial directions for the rollers housed in a roller housing space formed between the outer peripheral surface of the pin and the inner peripheral surface of the ring.

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.

摘要: A needle roller bearing comprises an outer ring having a plurality of outer ring members split by split lines extending in an axial direction of the bearing, a plurality of needle rollers arranged on an orbit surface of said outer ring so that they can roll thereon, and a cage holding the needle rollers at intervals. The outer ring member has a projection serving as a positioning engaging part which engages with a housing for positioning, and an engaging click protruding from an axial end of the outer ring member inward along a diameter to prevent the cage from moving in an axial direction, in positions shifted from its circumferential center.

摘要: Provided are a gear in which oil film formation between the tooth surfaces of gears rotating at high speed can be effected to a sufficient degree, in which generation of pitting, abrasion, and scoring is prevented, and which helps to prevent an increase in temperature and wear to achieve an improvement in durability, and a gear drive unit. A multitude of minute concave recesses are provided at random on a tooth surface, and an average area of the recesses is set to a range of 160 to 740 μm2. Accordingly, the tooth surface can obtain a high oil film forming capacity. Thus, even under a low-viscosity/thin-lubrication condition in which the thickness of the oil film is extremely small, it is possible to achieve a long service life.
