Abstract:
The effect
of the radial clearance on the life of roller bearing is described. The
larger the radial clearance, the shorter the life of the roller bearing.
The life equation, which is suitable for computing the life of the
roller bearing in mining tri-cone bit, is established. The designer
should consider comprehensively the effect of structure data and radial
clearance on the life of the roller bearing, in order to make optimum
design.
Key words:
Tri-cone bit Radial clearance Dynamic load rating
Roller bearing life
