Abstract
The invention relates to the assembly of a shaft bearing (,) in the end section (,) of a guide tube (,) of a brushcutter (,). The guide tube (,) accommodates a drive shaft. The bearing (,) is axially inserted into the end section (,) and is held so that it cannot separate therefrom. The outer diameter (D,) of the outer surface (,) of the bearing (,) is configured smaller than the inner diameter (D,) of the end section (,) in order to facilitate assembly and to ensure a force-tight inseparable seating of the bearing 16 in the end section. Several axial ribs (,) are distributed uniformly over the periphery of the outer surface (,). The radial elevation (H) of the axial ribs is slightly greater than approximately half the difference between the inner diameter (D,) of the end section (,) and the outer diameter (D,) of the surface (,) of the bearing (,). To mount the bearing (,), the end section is elastically deformed so far until the diameter (D,) is slightly greater than the axial maximum outer diameter (,) of the bearing (,). The diameter (D,) is measured from a corner (,) and the maximum outer diameter (,) is determined by the radial height (H) of the axial ribs (,). The end section (,) returns elastically in the direction toward its initial form after the axial insertion of the bearing (,). The bearing (,) is then surrounded force tight by the end section (,).
