Brief introduction: eccentric bearing ring is a size thrust needle roller bearing, bearing of knowledge

Thrust needle roller bearing eccentric bearing ring is a size at the same time of bearing ring is a size structure, by adopting the following measures to realize the long life (3 1) In order to prevent the lubricating oil to reduce the surface damage caused by the design guide in the bearing ring grooves. In addition, it is through the adoption of a shape structure bearing ring crank arm structure and embedded structure and implementation. By the decrease in the number of components to a minimum, not only control the rising costs, but also facilitate customer assembly operations. :( 2) In order to make the bearing retainer and the clearance between the bearing ring radius direction set is larger than of eccentricity, the internal structure is improved; ( 3) Using fem analysis, through optimize the shape and thickness, improve the retainer strength; In use the shape of the structure of the bearing rings at the same time, by improving the internal structure, at 0. Within 5 mm under the condition of eccentric life extension to the old products of more than four times. For torque converter under the condition of eccentric use purpose, such as Japan bearings manufacturer has developed and launched the 'thrust needle roller bearing eccentric bearing ring is a size'. Thus, there are on the market ( 1) Allow large eccentric, long life; ( 2) For the sake of embeddedness, bearing and retainer ring in order to realize the integration of the two requirements. But the old structure bearing cannot satisfy these two functions. Or even allow large eccentricity, but the structure is still the separation type; Either adopted a body structure, but does not allow large eccentricity. Use in the installation of the engine and torque converter parts of thrust bearing, usually in the engine and torque converter under the condition of eccentric installation. If do not allow the eccentric, bearing and retainer ring cover after contact, heat, wear and tear.
