HIGHLY-RELIABLE VIBRATION-PROOF TOOTH FOR ROTOR EXCAVATOR BUCKET

摘要

The invention relates to a highly-reliable vibration-proof tooth for rotor excavator bucket. According to the invention, the tooth is cast from the same material as the entire mass of the body and is defined by an apex having a sharpening angle ( α ) of 40...44°, by the self-wedging zone (c2) of the tooth which is profiled in the shape of a fir-tree, with two rows of three protuberances (1) symmetrically placed against a central crest (2), which is built-up with two layers of hard material up to a third of an active zone (a).
