Title:
METHOD FOR ASSEMBLING AND DEVICE FOR ASSEMBLING ROLLER BEARING
Document Type and Number:
WIPO Patent Application WO/2013/125393
Kind Code:
A1
Abstract:
When assembling a roller bearing, the present invention effectively prevents rollers (R) assembled to the inside of an outer race (W) from tilting or dropping out from the state immediately after assembly. After arranging the rollers (R) in an annular shape by means of an arrangement jig (14), the roller group (G) arranged in an annular shape is ejected from the arrangement space (26) of the arrangement jig (14), and is pressed into a guide hole (39) of an insertion jig (15). As a result, in the state of inhibiting the diameter of the roller group (G) from widening by means of the inner peripheral surface of the guide hole (39), a holding member (36) made from an elastic material is inserted within the roller group (G) in the state of the holding member (36) being elastically compressed in diameter. Thereafter, an ejection tube (38) configuring the insertion jig (15) is displaced in the axial direction, simultaneously ejecting the roller group (G) and the holding member (36) from the guide hole (39), simultaneously assembling same within the outer race (W).
