| 摘要 |
The present invention provides a wear element assembly comprising: a wear element comprising an aperture, a fastener configured to be inserted into the aperture of the wear element and also an aperture of a substrate underlying the wear plate such that when the fastener is inserted into the wear plate aperture and the substrate aperture, a first surface of the fastener contacts a wear plate aperture wall and a substrate aperture wall and a space is formed (a) between a second surface of the fastener and the wear plate and substrate aperture walls or (b) between the fastener and another structure within the wear plate or substrate apertures, and urging means configured to be inserted (a) between the second surface of the fastener and the wear plate and substrate aperture walls, or (b) between the fastener and another structure within the wear plate or substrate aperture, or (c) within the fastener, wherein, in use, the urging means exerts a force against the second surface of the fastener to urge the first surface of the fastener to frictionally engage with the wear plate and substrate aperture walls. Also provided is a fastener configured to secure a wear element to a substrate, the fastener comprising a tapered surface and an opposing untapered surface of an upper region, the tapered surface configured to be urged against an aperture wall of a wear element, the untapered surface configured to be urged by an urging means. The wear element and fastener are particularly suitable in mining equipment. |
