<p>The invention provides a method for forming an assembly of a pair of taper roller bearings (15, 16) in which the inner bearing rings (17, 22) are axially spaced apart by a first member such as a shaft (12) of an industrial gear unit and the outer bearing rings (20, 21) are maintained spaced apart by a second member such as a housing (11) with one of the inner or outer ring of each bearing (15, 16) being an axially outer bearing ring which is spaced axially further from the outer bearing than the other ring of that bearing. The method comprises forming an assembly of said two members and bearings (15, 16) in which the axially outer bearing ring of at least one of the bearings (15, 16) is a loose fit on one of the first and second members, and then axially moving said axially outer bearing ring (22) of said one bearing (16) which is loose fit in a direction towards the other bearing (15) to create a pre-load, and then increasing the degree of pre-load by further movement in said direction to effect elastic defamation of that ring (22) which initially was a loose fit and thereby create a shrink fit type interface load between that ring (22) of said one bearing and one of the first and second members.</p> |
