摘要： A high capacity radial-fit coupling bolt (or “expanding sleeve bolt”) has a pair of tapered sleeves about a shank of a bolt to which can be applied a tensioning load. An extrudable ring, or a compression ring, is interposed between a head nut or head flange at one end of the shank, and one end of an inner sleeve. A tensioning load is applied to the shank, the inner sleeve causing the outer sleeve to expand diametrically. At a preset load limit, the extrudable ring is extruded through at least one bore in a drive piston between the head nut and the extrudable ring, to allow shank to move relative to the inner sleeve until the tensioning load is fully applied. Alternatively, a drive member is provided between the head nut or head flange and the compression ring, and at a preset limit, the compression ring allows the shank to move relative to inner sleeve until the tensioning load is fully applied. The preset limit will typically correspond to the force required to fully expand the outer sleeve.

摘要： A hydraulic mantle system for a gyratory rock crusher enables the safe, quick and efficient replacement of a worn or deformed mantle. The system includes a main shaft, an annular nut, an annular hydraulic piston and an annular mantle. The main shaft has a flange and external threads adjacent the flange. The annular nut body has side surfaces and internal threads that are threaded onto the external threads of the main shaft. The annular hydraulic piston has side surfaces that slidingly engage the side surfaces of the annular nut body. The annular mantle has an upper neck portion and a lower edge portion. The main shaft extends through the upper neck portion. The upper neck portion of the annular mantle is compressed between the flange of the main shaft and the annular hydraulic piston.

摘要翻译： 高容量径向配合联接螺栓（或“膨胀套筒螺栓”）具有围绕可以施加张紧载荷的螺栓的柄部的一对锥形套筒。 可挤压环或压缩环插入在柄的一端处的头部螺母或头部凸缘和内部套筒的一端之间。 张紧载荷施加到柄部，内套筒使外套筒沿径向扩张。 在预设的负载极限下，可挤压环通过头部螺母和可挤压环之间的驱动活塞中的至少一个孔挤出，以允许柄相对于内套筒移动，直到张紧负载被完全施加。 或者，驱动构件设置在头螺母或头部凸缘和压缩环之间，并且在预设限制下，压缩环允许柄相对于内套筒移动，直到张紧负载被完全施加。 预设极限通常对应于完全展开外套筒所需的力。

摘要： A high-pressure sealing ring for hydraulic assemblies has a substantially—“L”-shaped body with a leg and foot, where an external heel-portion is designed to provide a “rolling” line of sealing contact with the seat in the cylinder or piston in which it is seated.
