Replaceable wearable part for machinery - has hard wear-resistant segments fitting onto softer support elements having two slits

摘要

The wear-resistant segments (4) are made of a hard material and have an inner recess (9) which opens towards the surface facing the support element (2). The outer edge area (6) of the support element can be fitted into the recess with positive engagement through relative movement. The support element whose outer edge can be made of a relatively soft material has for each wear resistant segment two slits (11,12) in which can be inserted a material section (9,10) which connects the walls of the recess (9) together. Each slit can have an insert slit with radial extension and a circumferential locking slit. ADVANTAGE - For rotors, mixing elements etc.. Longer service life. Locking keyed engagement avoids the need for fixing bolts which wear down quicker.
