ASSEMBLY METHOD FOR LACE INTEGRAL TYPE THRUST ROLLER BARING AND JIG FOR ASSEMBLY

摘要

PURPOSE:To surely prevent the breakdown of a lace and an abnormal wear and to improve reliability and durability by engaging the short cylindrical part of the jig in L shaped section consisting of the short cylindrical part and a flange part with the erected wall engaged with an assembly part. CONSTITUTION:The projecting part 15 inner-fitted to the erected wall 8 formed on the inner peripheral edge part of a lace 5 is formed on the assembly part 14 assembling a lace integral type thrust roller bearing. The jig 16 for preventing a reverse assembly is fitted to this erected wall 8. The jig 16 is formed in L shaped ring at its section by a short cylindrical part 17 and an outward flange part 18. The jig 16 is deeply engaged to the extent of not carelessly coming out of the lace 5 by inner-fitting from the end edge side of the wall 8 and approaching the end edge of the wall 8 into a gap 20. The assembly in the reverse direction connected to the breakdown and abnormal wear of a lace can surely be prevented.
