WEARING PART OF BUCKET OF LOADING OR EARTH-MOVING MACHINE, ITS FASTENING ELEMENT AND SYSTEM OF WEARING PART, BUCKET AND LOADING OR EARTH-MOVING MACHINE Russian patent published in 2013 - IPC E02F9/28 

FIELD: construction.

SUBSTANCE: wearing part for a bucket of a loading or an earth-moving machine equipped with at least one front edge plate with an engaging edge directed forward, having a forward direction (F) and a backward direction (B) and comprising a fastening section for fixation of a wearing part to the bucket, having a section of a tightening surface for interaction in the field of the contact surface with a section of the pressing surface on the fastening element, capable of installation and pressing in the opening in the front edge plate. The section of the tightening surface is arranged in the groove of the fastening section and stretches at the angle (α) to the specified direction so that whenever the fastening element is used during pressing, a force is created, which acts at the wearing part in the backward direction (B). The part comprises a facility for connection with the engaging edge, representing a hook section, which includes an inner surface of the hook, designed for arrangement oppositely to and interaction with a slant inclined upwards and directed forwards on the edge plate during usage. The slant and the inner section of the hook form an angle (β), making 35-60° with the horizontal plane stretching via the front edge plate, and the section of the tightening surface stretches at the angle (α), making 35-60° to the specified forward direction. The fastening element has a forward direction (F), which is capable of installation and pressing in the hole in the front edge plate of the bucket and having a section of the pressing surface on the first part that acts at the wearing part and stretches at the angle α to the forward direction so that when the fastening element is used in pressing, a force is created, which acts at the wearing part in the backward direction (B). It includes two parts interacting by means of a threaded joint, the first part is equipped with a threaded section and a fastening head, on which there is a section of the pressing surface. The first part of the fastening element is equipped with the first section and the second section of the pressing surface, arranged at different distances relative to the axis (A), stretching via the first part of the fastening element. The system of the wearing part comprising at least one wearing part. The bucket for the loading or earth-moving machine, including the system of the wearing part.

EFFECT: increased operational reliability.
