METHOD FOR DESIGNING THRUST NEEDLE BEARING, THRUST NEEDLE BEARING AND METHOD FOR MANUFACTURING THRUST NEEDLE BEARING

摘要

PROBLEM TO BE SOLVED: To provide a thrust needle bearing that has high quietness and reduced cost of manufacture relative to those of existing thrust needle bearings.;SOLUTION: A method for designing a thrust needle bearing includes: a step of providing a plurality of thrust needle bearings 100 having different first lengths L1 in a second direction of a back face 12 and inspecting acoustic property of the provided thrust needle bearings 100; and a step of determining design values of the first lengths L1 so that the acoustic property is within an allowable range.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2018,JPO&INPIT
