SPECIAL RADIAL CLEARANCE BETWEEN ROLLER TRACK AND ROLLER IN SPHERICAL ROLLER BEARING FOR 160 - 180MM TAPPER BORE

摘要

A bearing is a device to allow constrained relative motion between two or more parts, typically rotation or linear movement. The bearing makes many of the machines we use every day possible. Vibrating screen, Stone crusher and Compactor have inherent eccentric motion, a range of strong and robust spherical roller bearings are developed for these application. The Special Radial Clearance between roller track and roller in Spherical Roller Bearing for 160 - 180mm Tapper Bore comprises smooth rollers present in between the inner and outer metal surface in order to reduce the friction between the surfaces along with thermal expansion. The minimum clearance developed for special spherical roller bearing of diameter 160 - 180mm between the inner ring, outer ring and roller is 230 whereas in normal case it is 140 and the maximum clearance between the inner ring, outer ring and roller is 250 whereas its 200 in normal case. This shows that there is an increment of 6428% in minimum clearance and 25% increment in maximum clearance. Both extended clearances may be varied further upto ±25%.
