Mechanical system comprising a wear part and a support and a bucket comprising at least one such mechanical system

摘要

The present invention relates to a mechanical system (1) comprising a wear part (10) and a support (20) which are included in a heavy construction equipment. The support 20 includes a base 22, a nose 30 extending from the base 22 along the main axis X30, and a plurality of protrusions 30, And a housing (24). The mechanical system 1 is a machine system 1 in which the nose 30 is located in the vicinity of the body end 31 of the nose 30 and has at least six planes arranged such that opposite sides defining the range of regions of the first type are paired. 1 zone 40 and at least six planes located in the vicinity of the distal end 33 of the nose 30 and arranged opposite to each other to define the range of the zones of the second type, Has a second region 80 which is less inclined than the plane of the first region 40 located so as to extend along the body direction D31 with respect to the main axis X30.
