Wear-protective sleeve

摘要

A sleeve is configured to be fitted onto a rotating shaft and the sleeve includes a tubular portion extending in an axial direction and having a cylindrical-shaped sealing guide surface configured to contact a radial shaft seal. A flange extends outward from the tubular portion at least substantially in a radial direction that is perpendicular to the axial direction. A first target break line is defined between the tubular portion and the flange and is configured to facilitate separation of the flange from the tubular portion. Further, a second target break line is defined in or on the flange and is configured to facilitate tearing of the flange at least substantially in the radial direction of the flange up to the first target break line.

1. A wear-protective sleeve including:
a sleeve section extending axially and having a cylindrical sealing guide surface, a flange section having a first portion extending radially away from the sleeve section and a second portion, a target break section connecting the sleeve section to the flange section and being configured to facilitate separation of the flange section from the sleeve section, the second portion of the flange section extending axially between the first portion of the flange section and the target break section, and a tearing apparatus defined in or on the flange section and having a plurality of reduced-wall-thickness paths and a plurality of cutouts in the flange section, wherein the plurality of reduced-wall thickness paths alternate with the plurality of cutouts such that no portion of the tearing apparatus has a thickness equal to a flange thickness, the tearing apparatus extends continuously between a circumferential edge of the flange section and the target break section such that the tearing apparatus opens into the target break section, the tearing apparatus being a spiral-shape path such that the tearing apparatus extends in a direction having a circumferential dimension, the tearing apparatus being configured to facilitate tearing of the flange section in a radial direction, an axial direction, and a circumferential direction up to the target break section to facilitate tearing of the flange from the sleeve section.
